601 Mailability

1.0 General Standards

1.1 Determining Mail Processing Categories

1.1.1 Processing Categories

There are five mail processing categories for mailpieces: letter, flat, machinable parcel, irregular parcel, and outside parcel. USPS assigns each mailpiece to one of these categories based on the physical dimensions and characteristics of the mailpiece using the longest dimension as the length, regardless of the placement or orientation of the delivery address on the piece. See the physical standards for processing categories in 101 for retail (single-piece price) mail and 201 for Commercial Mail.

1.1.2 Determining Length and Height

Determine the processing category (see 1.1.1) based on the physical dimensions and characteristics of the mailpiece, without regard to address placement. Then, determine length and height as follows:

a. Letter-size pieces. For the purpose of determining mailability or machinability (see 1.1.3), the length is the dimension parallel to the delivery address as read; the height is the dimension perpendicular to the length.

b. Flat-size pieces. The length of a flat-size mailpiece is the longest dimension. The height is the dimension perpendicular to the length.

c. Parcels. The length is the longest dimension.

d. Customized MarketMail pieces. See 705.1.0.

1.1.3 Nonmailable and Nonmachinable Placement of Address

The placement of the address on a letter-size mailpiece may render a piece nonmailable or nonmachinable. If the length (the dimension parallel to the address) of a letter-size mailpiece is not at least 5 inches, it is nonmailable. If the height (the dimension perpendicular to the length) of a letter-size mailpiece is not at least 3-1/2 inches, it is nonmailable. If the aspect ratio (length divided by height) is not within 1.3 to 2.5 (inclusive), the piece is a nonmachinable letter. For example:

a. For a letter-size piece that is 4 inches by 6 inches, if the address is parallel to the 4-inch dimension, it is 4 inches long, which is less than the minimum length of 5 inches required in 201.1.1.1. Therefore, this piece is nonmailable.

b. Following the process in 1.1.2a, a piece that is 5 inches by 8 inches (and within letter-size thickness dimensions) is a letter. If the address is parallel to the 8-inch dimension, the piece is 8 inches long and 5 inches high. The aspect ratio of this piece is 1.6, so it is a mailable letter within machinable dimensions for length and height.

c. For a letter-size piece that is 5 inches by 8 inches, if the address is parallel to the 5-inch (shorter) dimension, the piece is 5 inches long and 8 inches high. The aspect ratio of this piece is 0.625, which is not within 1.3 to 2.5, so it is mailable as a nonmachinable letter.

1.2 General Mailability and Right of Refusal

Articles presented for mailing must be prepared under the general and specific standards in this document. The USPS accepts properly packaged and marked parcels but reserves the right to refuse nonmailable or improperly packaged articles or substances. Additional or other standards can apply to overseas military Post Offices and international mail.

1.3 Mailer’s Responsibility

It is the mailer’s responsibility to refrain from depositing nonmailable matter in the mail. The mailer must comply with applicable postal laws and regulations governing mailability and preparation for mailing, as well as nonpostal laws and regulations on the possession, treatment, transmission, or transfer of particular matter. Information about USPS standards is available from postmasters, business mail entry managers, and the PCSC manager (see 608.8.0).

3.0 Packaging

3.1 General

Mailers must package mailpieces to withstand normal transit and handling without breakage or deterioration of content, package breakage, injury to USPS employees, or damage to other mail. See 3.2 through 3.8 for specific types of items. Mailers must follow these additional standards for packaging:

a. Cushion (see 3.9) fragile items to withstand handling in processing, transportation, and delivery.

b. Package contents so they do not shift within the mailing container.

c. Brace and cushion heavy items to prevent damage to other mailpieces.

3.2 Stationery

Stationery-type items thicker than 1 inch or heavier than 1 pound are not accepted in letter-style envelopes. The contents of these packages must be secured by tying, banding, or using partitions on close-fitting interior containers to prevent shifting.

3.3 Odd-Shaped Items in Paper Envelopes

Pens, pencils, key rings, bottle caps, and other similar odd-shaped items are not permitted in letter-size or flat-size paper envelopes unless they are wrapped within the other contents of the envelope to streamline the shape of the mailpiece and prevent damage during postal processing. If an odd-shaped item is not properly wrapped, it could burst through the envelope and cause injury to employees and damage to USPS processing equipment. Odd-shaped items that are properly wrapped within paper envelopes and sent at letter prices may be subject to the nonmachinable surcharge under 133.1.5 or 233.4.3 for First-Class Mail letters, or the nonmachinable prices under 243.5.6.3 for Standard Mail letters. Certain types of odd-shaped items, when properly wrapped, are permitted as automation price letter-size mail subject to the standards in 201.3.0. Flat-size automation price mail is subject to the uniform thickness requirement in 201.3.0.

3.4 Liquids

Mailers must mark the outer container of a mailpiece containing liquid to indicate the nature of the contents. Mailers must package and mail liquids under the following conditions:

a. Use screw-on caps, soldering, clips, or similar means to close mailpieces containing liquids. Do not use only friction-top closures (push-down types).

b. Liquids in steel pails and drums with positive closures, such as locking rings or recessed spouts under screw-cap closures, may be mailed without additional packaging.

c. Package glass and other breakable containers of liquid with a capacity of more than 4 fluid ounces according to the following requirements:

1. Cushion the primary container with material sufficient to absorb all leakage in case of breakage.

2. Place the primary container inside another sealed, leakproof container (secondary container), such as a can or plastic bag.

3. Use an outer mailing container that is strong enough to protect the contents.

d. As an alternative to 3.4c. above, mailers may use containers certified by the International Safe Transit Association (ISTA) that passed ISTA's Test Procedure 3A. Mailers must provide their ISTA 3A Package-Product Certification Notice at the time of mailing as verification that the mailpieces they are submitting passed the required performance test.

3.5 Aerosols

Aerosols (containers under pressure) are hazardous materials and must be constructed to prevent accidental discharge of the contents during postal handling. Mailable aerosol containers must be packaged under 10.12.

3.6 Perishable, Hazardous, and Restricted Items

Mailpieces containing perishable, hazardous (including infectious substances), biological, or restricted materials are subject to standards in 8.0 through 12.0.

3.7 High-Density Items

High-density items are solid objects (such as tools, hardware, and machine and auto parts) whose weights are comparatively high for their volumes. Package high-density items weighing more than 15 pounds so that the contents do not exert more than 60 pounds per square foot on the smallest side of the mailing container.

3.8 Load Type

The following three terms describe types of loads, based on content, degree of protection, and strength of the mailing container.

a. An easy load contains items of moderate density that either completely fill the mailing container or are packaged in interior containers that completely fill the mailing container. Easy load items are not easily damaged by shock, compression, or puncture.

b. An average load contains moderately concentrated items packaged directly into a mailing container. Mailers can prepackage average load contents by nesting items within partitions or in separate paperboard boxes to stabilize items to prevent shifting and damage.

c. A difficult load contains items that require a high degree of protection to prevent shock, puncture, or distortion to the items or the mailing container. The Postal Service does not accept in paperboard boxes, bags, or wraps difficult loads such as fragile items; delicate instruments; and high-density, small-bulky items.

3.9 General Cushioning Standards

Loose-fill cushioning must overfill the container before closure to hold the item and prevent its movement to an outside surface of the container. When multiple items are inside a single mailing container, mailers must cushion items to protect them from each other as well as from external forces. Do not package high-density heavy items with fragile items unless extreme care is taken to separate them from each other. Mailers must adequately stabilize heavy items within the package.

3.10 Tape and Tape Size

Cellophane and masking tape may not be used for closure or reinforcement of packages but may be used to augment closures on envelopes or to cover staples. Paper tape must be at least 60-pound basis weight kraft. The adhesives on gummed tapes must be adequately activated before application and firmly applied with the tape extending at least 3 inches over the adjoining side of the box. Except for pressure-sensitive filament tape, tapes used for closure and reinforcement should be at least 2 inches (or 48 mm metric) wide. Nonreinforced plastic tapes must be at least as strong in the cross direction as in the machine (long) direction.

3.11 Adhesive

Adhesives used for closure on box flaps or on tapes must remain serviceable from -20 degrees to +160 degrees Fahrenheit. When using hot-melt adhesive, apply adhesive using one of these methods:

a. Apply hot-melt adhesive to 25% of the area where the outer flap lies over the inner flap.

b. Apply at least four strips of hot-melt adhesive on each part of the box flap where the outer flap overlays the inner flap as follows:

1. Use strips at least 3/16 inch wide after compression.

2. Place the strips not more than 1-1/2 inches apart, with the first strip no more than 1/2 inch from the center seam.

3. Place all strips along the full width of the inner flap.

3.12 Banding

When banding is used for closure and reinforcement, it must encircle the length and girth of the package at least once. If twine or cord is used for closure and reinforcement, it must be at least 20-pound tensile strength and secured at an intersection at least once on each side. Loose strapping and metal strapping are not acceptable.

3.13 Staples and Steel Stitching

Mailers may use staples or steel stitching to close boxes as follows:

a. Place the staples or stitching within 1-1/4 inches from the ends of the box.

b. Space staples or steel stitches not more than 5 inches apart for easy and average loads and not more than 2-1/2 inches apart for difficult loads. If placing staples farther apart, apply strips of 3-inch-wide reinforced tape in the gaps between the staples.

Tightly clinch staples to prevent protrusions. Mailers must remove and replace inadequately clinched staples before mailing.

f. Good, rigid, used boxes with all flaps intact are acceptable.

g. Boxes with difficult loads to out-of-town destinations must be reinforced with banding about every 8 inches in each direction around the package.

4.3 Fiberboard Tubes and Similar Long Containers

Mailers may use fiberboard tubes and similar lengthy containers for mailing if the containers meet the following requirements:

a. The length must not exceed 10 times the girth.

b. When using friction slide closures as end caps, reinforce closures by encircling all seams with tape. Crimped or taped end closures are acceptable only for lightweight rolled items (such as posters or charts).

c. The strength of the tube ends must be at least equal to the tube sidewall strength, unless the contents are lightweight rolled items.

d. Sidewall strength of tubes must be equal to solid fiberboard that is:

1. At least 1/16 inch thick for tubes less than 18 inches long.

2. At least 3/32 inch thick for tubes 18 to 32 inches long.

3. At least 5/32 inch thick for tubes more than 32 inches long.

4.4 Paper Bags and Wraps

For easy loads of up to 5 pounds, paper bags and wraps are acceptable when at least of a 50-pound basis weight (the strength of an average large grocery bag) and the items are immune from impact or pressure damage. A combination of plies adding up to or exceeding 50-pound basis weight is not acceptable. For easy and average loads of up to 20 pounds, reinforced bags or bags with a minimum of 70-pound basis weight are acceptable. Nonreinforced loose-fill padded bags are not acceptable as exterior containers, unless the exterior ply is at least 60-pound basis weight.

4.5 Plastic Bags

Plastic bags must be at least 2 mil thick polyethylene or equivalent for easy loads up to 5 pounds; 4 mil thick for easy loads up to 10 pounds.

4.6 Plastic Film

Heat-shrinkable plastic film—either irradiated polyethylene, linear low-density polyolefin, or copolymer—may be used as packaging for mailpieces under the following conditions only:

a. Film must be at least 3/4 (0.75) mil thick for an easy load up to 5 pounds.

b. Film must be at least 1-1/4 (1.25) mil thick for an average load up to 5 pounds.

c. Film must be at least 1-1/2 (1.5) mil thick for an average load parcel up to 10 pounds, only when mailers prepare the parcels on 5-digit/scheme, merged 5-digit/scheme, or finer level pallets.

d. When requested, mailers must provide written certification that these types of film are being used.

4.7 Cloth Bags

Cloth bags are acceptable for easy and average loads of up to 10 pounds, if the seams of the bags equal the strength of the basic material.

4.8 Difficult Load

The USPS does not accept bags, bales, or wraps with difficult loads. The contents in bags, bales, and wraps must be compressed when possible.

4.9 Bales

Bales are acceptable within postal weight limits, if adequately compressed and reinforced to contain the material.

4.10 Cans and Drums

Mailers may mail items in cans and drums with positive closures (such as clips). Friction closures alone are not acceptable. Mailers must shield protruding devices, such as locking rings, with padding material to prevent injury to USPS employees and damage to equipment or other mail.

5.0 Handling, Content, and Extra Service Markings

5.1 Handling, Content, and Extra Service

Certain markings may be used to identify handling, content, and extra service. Unauthorized markings not designating price, class, address, handling, content, or extra service are not permitted. Extraneous information, which can be confused with ZIP Codes, may not be placed next to or directly under the last line of the delivery address. Any obsolete marking on a container to be reused for mailing must be obliterated. The following markings must be placed in an area below the postage and above the addressee’s name in the delivery address and to the right of the return address:

a. Handling markings such as “Fragile” must be applied only to packages containing delicate items such as glass and electrical appliances.

b. Content markings such as “Perishable” must be applied to any package containing items or substances that can degrade or decompose rapidly such as meat, produce, plants, or certain chemical and hazardous materials samples. Restricted and hazardous articles must be marked and labeled under applicable standards. A container improperly identified by content is not acceptable for mailing (e.g., a box marked “Art Supplies” that contains flammable liquid or a box marked “Bleach” that contains clothing).

c. Extra service markings such as “Return Receipt Requested” must use the wording or label required by the applicable extra service standards.

5.2 Method

The mailer must mark the package using material that is not readily water soluble or easily smeared or rubbed off. The marking must be readable at a distance of 30 inches. Marking methods or surfaces must permit application and retention of adhesive stamps, postage meter impressions, and postal endorsements made with hand stamp, ballpoint pen, or Number 2 pencil. Any address label or envelope must be firmly affixed to the mailing container, with no more than an 1/8-inch separation between the ends of the label or envelope and the container.

Back to Top

6.0 Mailing Containers—Special Types of Envelopes and Packaging

6.1 Priority Mail Express and Priority Mail Packaging

Priority Mail Express and Priority Mail packaging provided by the USPS must be used only for Priority Mail Express or Priority Mail, as applicable. Regardless of how the packaging is reconfigured or how markings may be obliterated, any matter mailed in USPS-provided Priority Mail Express or Priority Mail packaging is charged the appropriate Priority Mail Express or Priority Mail price.

6.2 Critical Mail Envelopes

Critical Mail letter-size and flat-size envelopes are provided by USPS and must be used only for Critical Mail. Use of these envelopes is restricted to eligible matter and postage payment methods (see 224.1.1 and 224.1.1). Matter mailed in USPS-produced Critical Mail envelopes that do not meet the criteria for Critical Mail are charged the appropriate Priority Mail Commercial Plus Flat Rate Envelope prices (volume thresholds apply).

6.3 Green Diamond Border Envelope

An envelope or card bearing a green diamond border must be used only for First-Class Mail. Any envelope or card bearing a green diamond border is charged the appropriate First-Class Mail price, regardless of mail content or of requested class or service. When printed on letter-size mail, the border must not enter the OCR read area or barcode clear zone unless a delivery point barcode appears in the address block as described in 202.5.2.

6.4 Window Envelope

For all letter-size and flat-size mail in window envelopes, every character in the delivery address, including any postal barcode, marking, or endorsement, must be completely visible through the window throughout the full range of movement of the insert bearing the delivery address. Any window envelope used for letter-size or flat-size mail claimed at automation prices or for letter-size mail claimed at Enhanced Carrier Route high density or saturation prices must also meet the barcoding standards for letters and flats in 708.4.0. Any window envelope used for letter-size or flat-size mail must meet the following additional standards:

a. The address and any barcode visible through the window must be printed on white paper or paper of a very light color.

b. A clear space of at least 1/8 inch is required between the address block, which includes any optional endorsement line, and the top, bottom, and left and right edges of the address window, and must remain when the insert is moved to its full limits in each direction within the envelope to ensure efficient processing and delivery. See 202.5.2 (letters) or 202.5.3 (flats) for barcode clearances when the address block contains a barcode. For nonautomation price mail, the bottom edge of the address window must not extend more than 1/8 inch into the barcode clear zone as defined in 202.5.1. Any letter-size envelope containing a window that intrudes into the barcode clear zone is not eligible for NCOALinkMPE system processing options for the Move Update standard.

c. Window cover material, if used over the address window, must be made of a nontinted clear or transparent material (e.g., cellophane or polystyrene) and must permit the address, as viewed through the window material, to meet the print contrast ratio (PRC) standards in 708.4.0 to ensure efficient processing and delivery. Glassine may be used for window cover material. All edges of the window cover material must be glued securely to the envelope. The bottom edge of an address window must be at least 1/2 inch from the bottom edge of the envelope.

d. For letter-size mail, the delivery address window must be parallel with the longest edge of the envelope. For flat-size mail, the address window may be parallel with any edge of the envelope.

e. For Registered Mail, the opening on a window envelope must be covered as described in 503.2.3.5.

6.5 Reusable Mailpiece

A reusable mailpiece is an envelope, self-mailer, or similar mailpiece designed for two-way mailing. The recipient removes part of the original mailpiece or refolds the piece to cover the delivery address of the recipient and reveal the delivery address of the originator (sender) for return. Except for reusable mailpieces that originate as permit imprint mailings, the piece must meet these standards:

a. Basic Design. The piece must be designed and constructed to allow the recipient to reconfigure the piece to remove or obscure the address, barcode, postage, and any marking or endorsement applied to the piece when it was originally mailed so that these elements are not mistaken by the USPS as applying to the returned piece. The instructions on the piece must ensure that the recipient can prepare the piece correctly for remailing. If a reusable mailpiece does not meet the applicable standards, the piece must be re‑enveloped and new postage affixed before distribution by the originator.

b. Distribution. When the piece is mailed by the originator, the piece must show only one complete delivery address and, if used, the corresponding barcode; the appropriate postage; and any required marking or endorsement. The originator’s address and barcode for returning the piece and any postage, marking, endorsement, and facing identification mark (FIM) provided for that purpose must be obscured so that they are not mistaken by USPS employees or postal mail processing equipment as applying to the originating piece.

c. Return. When the piece is reconfigured for return from the recipient to the originator, the piece must show only one complete delivery address and, if used, the corresponding barcode; the appropriate postage; and any required marking, endorsement, and FIM. If a reusable mailpiece does not meet the applicable standards, the piece must be re‑enveloped and new postage affixed before return by the recipient.

6.6 Alternative Reusable Mailpieces That Originate as Permit Imprint Mailings

6.6.1 Basic Design

The piece must be designed and constructed so that the recipient may reconfigure or modify it to remove or obscure the address that applied to the piece when it was originally mailed. The instructions on the piece must ensure that the recipient can prepare the piece correctly for remailing. If a reusable piece does not meet the applicable standards, the piece must be re‑enveloped and new postage affixed before distribution by the originator.

6.6.2 Distribution

When reusable mailpieces are originally mailed, postage must be paid with permit imprint and a complete address and corresponding barcode must be located in the address block. Reusable pieces must be entered at a postal facility as part of a permit imprint mailing. On mailpieces other than window envelopes, the address block for return of the piece (including the delivery address and a corresponding barcode) will be located on the reverse side. If included, prepaid reply postage must be located or obscured so that it is not mistaken by postal mail processing equipment or employees as applying to the originating piece.

6.6.3 Return

When the piece is reconfigured for return from the recipient to the originator, only one complete address with a corresponding barcode located in the address block and a FIM must be visible on the piece. If a reusable mailpiece does not meet the applicable standards, the piece must be re‑enveloped and new postage affixed before return by the recipient.

6.6.4 Two-Way Indicia

When the permit imprint indicia for Standard Mail or First-Class Mail is printed on a reusable window envelope intended to be returned as Business Reply Mail (BRM), the imprint “NO POSTAGE NECESSARY IF MAILED IN THE UNITED STATES” must be printed on the envelope directly below the permit imprint indicia. See Exhibit 601.6.6.4 below. These additional conditions apply:

a. The permit imprint indicia must be located in the upper right corner of the address side of the mailpiece.

b. The horizontal bars must be printed directly below the “NO POSTAGE NECESSARY” imprint and must not extend below the delivery line of the address.

c. The other BRM elements as described in 505.1.8, with the exception of the Facing Identification Mark (FIM), must appear on the insert in the envelope window. The FIM C must be printed on the envelope under 708.9.0.

d. The outgoing First-Class Mail portion with two-way indicia must be endorsed “Return Service Requested,” except for mailpieces participating in Address Change Service (ACS). First-Class Mail letters participating in ACS must be endorsed “Change Service Requested” for traditional ACS. Mailpieces with Intelligent Mail barcodes and requesting OneCode ACS must have the printed endorsement “Electronic Service Requested,” but the embedded request must be for “Change Service Requested” (option 1) only. Endorsements must not appear directly below or to the left of the postage area, and must not be visible when the mailpiece is configured for reply purposes (see 507.4.2 and Exhibit 507.1.5.1).

e. Standard Mail with two-way indicia should not be forwarded, and must not be endorsed “Address Service Requested” or “Forwarding Service Requested.”

7.0 Packaging Standards for Mail Processed at Network Distribution Centers

7.1 High-Density Items

High-density items (see 3.7) weighing from 20 to 45 pounds must be packaged in fiberboard boxes constructed of a minimum 200-pound test board or equivalent wood, metal, or plastic containers. Plastic, metal, and similar hard containers must be packaged, treated, or otherwise prepared so that their coefficient of friction or ability to slide on a smooth, hard surface is similar to that of a domestic-class fiberboard box of the same approximate size and weight. Closure must be done by staples, heat-shrinking, adhesives, or tape. Boxes without inner packing or containing loose material must be reinforced or banded with reinforced paper or plastic tape, pressure-sensitive filament tape, or firmly applied nonmetallic banding. Internal blocking and bracing, including the use of interior containers, cut forms, partitions, dunnage, and liners, must be used as required so that packages are capable of maintaining their integrity without damage to the contents if dropped once on one of their smallest sides on a solid surface from a height of 3 feet. These items from 45 to 70 pounds must be similarly packaged, closed, and reinforced, except that exterior containers must be a minimum of 275-pound test fiberboard or equivalent.

7.2 Books

Books and similarly produced printed matter (such as catalogs) fastened together along one edge between hardback, paperback, or self-covers, that are more than one inch thick or one pound must not be accepted in letter-style non-reinforced flat envelopes or without packaging. Envelopes meeting the standards in 4.1b., or other appropriate packaging materials in 4.0, must be used. Void spaces within multiple book containers must be filled with dunnage or otherwise stabilized to prevent shifting or damage to the contents or container. Shipments of books and similarly produced printed matter are packaged according to these weight categories:

a. Up to five pounds, sealing must be by multiple friction closures, completely clinched staples, heat-sealing, adhesives, tape, or nonmetallic banding. Although shrinkwrap is not acceptable as the only packaging for hardback books and similarly produced printed matter exceeding one pound or one inch thick, it may be used on the exterior of otherwise acceptable containers. Shrinkwrap (under 4.6) may be used as the only method of packaging for paperback books and similarly produced printed matter up to three pounds.

b. From 5 to 10 pounds, closure must be by tape, nonmetallic banding, or adhesives. Reinforced tape or nonmetallic banding is adequate for both closure and reinforcement. Nonmetallic banding must be firmly applied to the point that the straps must be tightened until they depress the carton at the edges.

c. From 10 to 25 pounds, reinforced tape or nonmetallic banding is adequate for closure and reinforcement. Nonmetallic banding must be firmly applied to the point that the straps tighten until they depress the carton at the edges.

d. From 25 to 50 pounds, hardbound books and similarly produced printed matter must be packaged in 275-pound test fiberboard boxes and paperback books and similarly produced printed matter must be packaged in 200-pound test fiberboard boxes.

e. From 50 to 70 pounds, hardbound books and similarly produced printed matter must be packaged in 350-pound test fiberboard boxes and paperback books and similarly produced printed matter must be packaged in 275-pound test fiberboard boxes.

7.3 Soft Goods

Boxes containing soft goods (e.g., textiles, clothing, sheets, blankets, pillows and pillowcases, draperies, cloth, and any wearing apparel) weighing up to 5 pounds must be filled to capacity. Soft goods between the weight range of 5 to 20 pounds must be packaged in material with a minimum 70-pound outer ply basis weight. Closure of bags must be by completely clinched staples, heat-sealing, adhesives, sewing, or tape. Improperly clinched staples must be removed. Shrinkwrapping is not acceptable as the only packaging. Fiberboard containers must be made of at least 200-pound test board for soft goods weighing from 20 to 45 pounds and at least 275-pound test board for soft goods weighing from 45 to 70 pounds.

7.4 Sound Recordings

Shipments of recordings (e.g., records and cassette tapes in paper sleeves, paperboard, or chipboard shells) weighing up to 10 pounds must be packed in 70-pound basis weight envelopes for weights up to 3 pounds, or outer corrugated, fiberboard containers for weights up to 10 pounds. When shipments weigh from 20 to 40 pounds, multiple shell containers must be packaged in 175-pound test fiberboard containers or equivalent and closed and reinforced by adhesives, kraft paper tape, equivalent plastic tape, or staples. When shipments weigh from 40 to 65 pounds, multiple shell containers up to 65 pounds must be packaged in 200-pound test fiberboard containers or equivalent and closed and reinforced as described for 20- to 40-pound containers, except that containers must be reinforced about every 8 inches around the package. Shipments weighing more than 65 pounds must be packaged in 275-pound test fiberboard containers or equivalent.

7.5 Magnetic Tapes

Shipments of multiple magnetic tapes and cartridges up to 5 pounds must be packed in outer fiberboard containers or chipboard containers (minimum 0.022 mil). Closure must be by multiple friction closures, completely clinched staples, heat-shrinking or adhesives, or by tape. Paper tape must be a minimum of 60-pound basis weight kraft. Shrinkwrapping is acceptable on the exterior of otherwise acceptable boxes of multiple tape shipments. Standards for shipments weighing from 5 to 20 pounds are similar, except that closure must be only by the use of adhesives, tape, or staples. Standards are also similar for shipments weighing from 20 to 40 pounds, except that the contents must be placed in 175-pound test containers that are banded or reinforced at two points with reinforced paper or plastic tape, pressure-sensitive filament tape, or firmly applied nonmetallic banding. Shipments from 40 to 65 pounds must be similarly packaged, except that fiberboard containers of at least 200-pound test board or equivalent must be used. Shipments weighing more than 65 pounds must be packaged in 275-pound test fiberboard containers or equivalent.

8.0 Nonmailable and Restricted Articles and Substances Generally

8.1 Nonmailable Matter—General

Certain potentially undesirable, harmful, or dangerous matter is nonmailable by statute or regulation. The standards for nonmailable articles and substances and the special conditions under which certain of these articles and substances may be mailed are in 8.0 through 10.0 and 12.0. The standards in 13.0, 508.9.0, and 508.10.0, apply to nonmailable matter in written, printed, or graphic form and contain the rules on advising mailers of matter covered in 8.0 through 13.0, 508.9.0, and 508.10.0. The standards in 8.0 through 10.0 and 12.0 apply to the military postal system, its employees, and undelivered mail that is or has been in the official custody of this system and its employees. References to Inspection Service apply to the Postal Inspection Service and authorized employees, not military investigative services.

8.2 Basic Premise

The basic premise of the postal mailability statutes is that anything “which may kill or injure another, or injure the mails or other property...” is nonmailable. Several statutory exceptions to this rule permit mailings of otherwise nonmailable matter under specified conditions. Statutory exceptions apply to live scorpions, poisonous drugs and medicines, poisons for scientific use, switchblade knives, firearms, motor vehicle master keys, locksmithing devices, and abortive and contraceptive devices. The statutes also provide that the USPS may, by regulation, permit the mailing, under required conditions of preparation and packing, of potentially harmful matter not “outwardly or of [its] own force dangerous or injurious to life, health, or property.” The standards in 8.0 summarize the statutory prohibitions and exceptions. The mailability standards that apply to perishable, hazardous, and restricted matter are detailed in 9.0, 10.0, and 12.0, respectively. Publication 52, Hazardous, Restricted, and Perishable Mail, contains additional clarification and further describes the conditions of preparation and packaging under which the USPS accepts for mailing potentially harmful matter that is otherwise nonmailable. Publication 52 also contains detailed information on the mailability of specific hazardous materials.

8.3 Other Nonmailable Matter

Matter is nonmailable also when it cannot be delivered because of an illegible, incorrect, or insufficient address, or when it does not meet USPS standards for mail preparation, classification, postage prices, size, or weight.

8.4 Restricted Matter—General

Restricted matter is an article or substance prohibited or limited by Title 18, U.S. Code (liquors, abortive and contraceptive devices, odd-shaped items in envelopes, motor vehicle master keys, and locksmithing devices). It also includes matter not otherwise described in 8.0 through 10.0 and 12.0 that is restricted by 18 USC 1716(a) because it may, under conditions encountered in the mail, be injurious to life, health, or property (obnoxious odors, liquids, powders, and battery-powered devices).

8.5 Harmful Matter—General

Except as provided in this document, any article, composition, or material is nonmailable if it can kill or injure another or injure the mail or other property. Harmful matter includes, but is not limited to:

a. All types and classes of poisons, including controlled substances.

b. All poisonous animals except scorpions mailed for medical research purposes or for the manufacture of antivenom; all poisonous insects; all poisonous reptiles; and all types of snakes, turtles, and spiders.

c. All disease germs or scabs.

d. All explosives, flammable material, infernal machines, and mechanical, chemical, or other devices or compositions that may ignite or explode.

8.6 Hazardous Materials

Harmful matter also includes regulated hazardous materials as defined in 10.0 that are likely to harm USPS employees or to destroy, deface, or otherwise damage mail or postal equipment. This includes materials such as caustic poisons (acids and alkalies), oxidizers, or highly flammable liquids, gases, or solids; or materials that are likely, under conditions incident to transportation, to cause fires through friction, absorption of moisture, or spontaneous chemical changes or from retained heat from manufacturing or processing, including explosives or containers previously used for shipping high explosives with a liquid ingredient (such as dynamite), ammunition, fireworks, radioactive materials, matches, or articles emitting obnoxious odors.

8.7 Marking of Restricted Articles or Substances

8.7.1 Content

Except for firearms and switchblade knives, controlled substances, radioactive materials, and motor vehicle master keys and locksmithing devices, the identity of the content of anything mailed under 8.0 through 10.0 and 12.0 must be plainly and durably marked on the address side of each mailpiece as a condition of mailing. When the content is a hazardous material as defined in 49 CFR, each mailpiece must be marked as required in 10.0.

8.7.2 Addressing

For any matter mailed under the provisions in 8.0 through 10.0 and 12.0, the recipient’s name and address must be affixed or applied directly to the mailpiece using a material or method that is not water-soluble and not easily smeared or rubbed off. Except for diagnostic specimen mailpieces using a business reply mail format and nonregulated materials, a return address that includes the sender’s name and address must appear on all matter mailed under 8.0 through 10.0 and 12.0. The return address, when required, must be applied using a material or method that is not water-soluble and not easily smeared or rubbed off.

8.7.3 Warning Label

Except for controlled substances mailed under 12.0, any label or other marking required by federal law or the regulation of any federal agency must be securely affixed or applied to the address side of each mailpiece. See 10.0 for the warning label requirements that apply to the mailing of hazardous materials.

8.8 Mailer Responsibility

The mailer must comply with applicable postal laws and regulations governing mailability and preparation for mailing, as well as nonpostal laws and regulations on the shipment of particular matter.

8.9 Statutory System

18 USC 2510, et seq., constitutes a statutory system of regulating interception of wire, oral, or electronic communications. Any person contemplating the mailing of a device primarily useful for surreptitiously effecting such interception should consider the provisions of 18 USC 2510, et seq., particularly section 2512. This statute makes it a crime, except as otherwise provided in 18 USC 2510, et seq., for a person intentionally to send through the mail any device whose design that person knows, or has reason to know, renders the device primarily useful for surreptitious interception of wire, oral, or electronic communications. The statute does not declare that such a device in itself constitutes nonmailable matter but, as indicated, provides criminal penalties for the act of intentionally mailing it.

8.10 Other Laws and Regulations

Particular matter may be mailable under postal statutes and regulations, but customers may have responsibilities under nonpostal statutes and regulations concerned with possession, treatment, transmission, or transfer of such matter (e.g., 49 CFR 100-185 (Department of Transportation Regulations); the Comprehensive Drug Abuse Prevention and Control Act of 1970 (Public Law 91-513), 21 USC 801, et seq.; and the Gun Control Act of 1968 (Public Law 90-618), 18 USC 921, et seq.).

8.11 Refusal of Nonmailable Matter

USPS employees may refuse an article for mailing if the content of the article is described by the mailer or otherwise revealed to be nonmailable.

8.12 Authorizing Mailability

A postmaster may decide whether articles and substances other than written, printed, or graphic matter are nonmailable and, where appropriate, is authorized to refuse to accept for mailing such matter determined to be nonmailable. The mailer may seek a review of the postmaster’s decision by the PCSC. The mailer may file a written appeal of the PCSC ruling with the USPS Recorder, Judicial Officer, with a copy or description of the determination or ruling. The rules of procedure for the determination of such appeals are in 39 CFR 953.

8.13 Protecting Employees

A postmaster may take any step reasonable and necessary to protect USPS employees and equipment from potentially dangerous or injurious materials or substances found in the mail.

8.14 Applicability to Military Postal System

8.0 through 10.0 and 12.0 applies to the military postal system, its personnel, and undelivered mail that is or has been in the official custody of that system and its personnel. References to the Inspection Service refer to the Postal Inspection Service and its authorized employees, not to military investigative services.

9.0 Perishables

9.1 Time Factor

Mailable perishable matter may be sent through the mail only if it can reach its destination in good condition in the normal transit time between the mailing and address points. Mailable perishable foods that do not rapidly decay or generate obnoxious odors in the mail may be sent at the mailer’s risk.

9.2 Preparation of Perishables

9.2.1 Container

Any container used to mail perishable matter must be constructed to protect and securely contain the contents.

9.2.2 Produce

Fruits and vegetables are not mailable unless presented in dry condition.

9.2.3 Water Ice

9.2.4 Dry Ice

A parcel containing dry ice (carbon dioxide solid) must be packed in a container that allows the release of carbon dioxide gas. If a fiberboard box is used, enough insulation is necessary to prevent condensation and wetting of the mailing carton.

9.3 Live Animals

9.3.1 Prohibition on Animals Intended for Use in an Animal Fighting Venture

An animal is nonmailable if such animal is being mailed for the purpose of having it participate in an animal fighting venture (7 U.S.C. 2156). This standard applies regardless of whether such venture is permitted under the laws of the state in which it is conducted. Violators can be subject to the criminal penalties in 18 U.S.C. 49. See 12.20 for the prohibition on mailing sharp instruments intended for use in an animal fighting venture and 13.5.7 for restrictions on mailing written, printed, or graphic matter related to animal fighting ventures. For this standard:

a. the term animal means any live bird, or any live mammal (e.g., dog), except human;

b. the term animal fighting venture means any event, in or affecting interstate or foreign commerce, that involves a fight conducted or to be conducted between at least two animals for purposes of sport, wagering, or entertainment (excluding any activity whose primary purpose involves using one or more animals in hunting other animals); and

c. the term state means any state of the United States, the District of Columbia, the Commonwealth of Puerto Rico, or any U.S. territory or possession.

9.3.2 Day-Old Poultry

Day-old poultry vaccinated with Newcastle disease (live virus) is nonmailable. Live day-old chickens, ducks, emus, geese, guinea fowl, partridges, pheasants (pheasants may be mailed only from April through August), quail, and turkeys are acceptable in the mail only if:

a. They are not more than 24 hours old and are presented for mailing in the original unopened hatchery box from the hatchery of origin.

b. The date and hour of hatching is noted on the box by a representative of the hatchery who has personal knowledge thereof. (For COD shipments made by a hatchery for the account of others, the name or initials and address of the hatchery or the Post Office box number and address of the hatchery must be prominently shown for this standard.)

c. The box is properly ventilated, of proper construction and strength to bear safe transmission in the mail, and not stacked more than 10 units high.

d. They are mailed early enough in the week to avoid receipt at the office of address, in case of missed connections, on a Sunday, on a national holiday, or on the afternoon before a Sunday or holiday.

9.3.3 Small Cold-Blooded Animals

Small, harmless, cold-blooded animals (except snakes and turtles) that do not require food or water or attention during handling in the mail and that do not create sanitary problems or obnoxious odors are mailable (e.g., baby alligators and caimans not more than 20 inches long, bloodworms, earthworms, mealworms, salamanders, leeches, lizards, snails, and tadpoles).

9.3.4 Adult Birds

Disease-free adult birds, weighing no more than 25 pounds, may be mailed domestically. Mailers must comply with all applicable governmental laws and regulations, including the Lacey Act, the Endangered Species Act (ESA), and regulations of the U.S. Department of Agriculture, U.S. Fish and Wildlife Service, and any state, municipal or local ordinances. Mailings must also be compliant with the guidelines provided in USPS Publication 14, Prohibitions and Restrictions on Mailing Animals, Plants, and Related Matter, Chapter 5. In addition, each container or package must be marked as required by U.S. Fish and Wildlife Service under 50 CFR 14. Adult birds are mailable as follows:

a. The mailer must send adult birds by Priority Mail Express in secure containers approved by the manager, Product Classification (see 608.8.0 for address).

b. The number of birds per parcel must follow the container manufacturer limits and each bird must weigh more than 6 ounces.

9.3.5 Warm-Blooded Animals

Warm-blooded animals, except for adult birds and specified day-old birds under the specific conditions in this section, are not mailable (e.g., hamsters, mice, rats, guinea pigs, rabbits, cats, dogs, and squirrels).

9.3.6 Mailed to the Pacific Islands

Animals mailed to the Republic of Palau, the Republic of the Marshall Islands, and the Federated States of Micronesia require a permit issued by the government of the destination country.

9.3.7 Bees

Bees are acceptable in the continental surface mail when shipped under federal and state regulations to ensure that they are free of disease. Packages of honeybees must bear special handling postage, except those sent at a First-Class Mail price. Only queen honeybees may be shipped via air transportation. Each queen honeybee shipped via air transportation may be accompanied by up to eight attendant honeybees.

9.3.8 Other Insects

Other live, nonpoisonous, and nondisease-conveying insects, including flies of the family Drosophilidae, may be sent through the mail when properly prepared for mailing and when shipped under regulations of the U.S. Department of Agriculture. Such insects mailed to the Republic of Palau, the Republic of the Marshall Islands, and the Federated States of Micronesia are also subject to the regulations of the destination country.

9.3.9 Live Scorpions

Live scorpions that are to be used for medical research or the manufacture of antivenin are accepted only in the continental surface mail when packaged in a double mailing container, both parts of which are closed or fastened to prevent escape of the scorpions. The inner container must be of material that cannot be punctured by the scorpions and must be plainly marked “Live Scorpions.” Cushioning material must be used when necessary to prevent shifting of the inner container. The outer container must be strong enough to prevent crushing of the package or exposure of the contents during normal handling in the mail. The outer container must be plainly marked “Live Scorpions.”

9.3.10 Packaging

[1-26-14] Any mailing container used for mailable animals must be made of at least 275-pound test, double wall, corrugated, weather-resistant fiberboard (W5c) or equivalent and must be adequately ventilated. The container must be constructed to prevent escape of the animals while in the mail and to preclude the container and its contents from being crushed in normal handling. The outside of the container must include a return address and a description of the contents. A container marked “If Undeliverable, Abandon” is not accepted. USPS-produced packaging, including Flat Rate containers, is not eligible for shipping live animals.

9.3.11 Acceptance

The USPS does not accept any shipment of animals that the USPS reasonably believes cannot reach its destination in a viable condition. Such a determination is based on factors including the expected temperatures (weather conditions) while the shipment is in the mail; the types of vehicles on which the shipment is to be transported; the expected transit time; and the types of packaging used for protection against suffocation, crushing, and handling.

9.3.12 Disposal

Any parcel of live animals that cannot be delivered to the addressee or returned to the sender within 72 hours (for live day-old poultry) or within the delivery period marked on the parcel (for other animals) is immediately disposed of under the relevant standards. A parcel not marked with the delivery period is disposed of immediately if it reasonably appears that the animals cannot be returned to the sender in a viable condition.

9.4 Dead Wild Animals

The dead bodies, or parts thereof, of any wild animals, wild birds, or eggs are acceptable for mailing only when they are lawfully killed or taken, and their shipment is not prohibited by law of the United States or of the state, territory, district, or foreign country or subdivision thereof in which killed or taken or offered for shipment. Mailing of fresh game is also subject to these standards.

9.5 Furs, Hides, Skins, And Pelts

A parcel containing the fur, hide, skin, or pelt of a wild animal is mailable only if the matter is properly dried or cured and has no offensive odor, and only if the parcel is plainly marked, labeled, or tagged on the outside with the names and addresses of the shipper and addressee. The parcel must bear any endorsement required by state laws. Hides and pelts must be wrapped when necessary to prevent damage to other mail.

9.6 Mailing Plants

9.6.1 Mailability

In general, plants and plant products are mailable within the United States and its territories and possessions, subject to certain prohibitions imposed under U.S. agriculture and conservation statutes. To the extent specified below, when such prohibitions make shipment of plants or plant products unlawful, those articles constitute nonmailable matter. More detailed information is in Publication 14, Prohibitions and Restrictions on Mailing Animals, Plants, and Related Matter.

9.6.2 Nonmailable Quarantined Matter

Under 39 USC 3014(b), any plant, plant product, or other article capable of carrying a dangerous plant disease or insect infestation is nonmailable from a quarantined area, if shipping such item by common carrier is prohibited by a U.S. Department of Agriculture (USDA) quarantine issued under 7 USC 161, except, any such item is mailable from a quarantined area if:

a. Its movement by common carrier is allowed under conditions prescribed in the quarantine notice or in other USDA regulations, issued under 7 USC 161, governing its inspection, disinfection, certification, and other conditions for its movement.

b. Its movement by mail complies with all such conditions.

9.6.3 Additional Quarantined Matter

Any plant, article, or matter, the importation or interstate shipment of which is prohibited under the Act of August 20, 1912 (37 Stat. 315, chapter 308; 7 USC 151 et seq.), commonly known as the Plant Quarantine Act, is made nonmailable by 39 USC 3015(c).

10.0 Hazardous Materials

10.1 Definitions

[4-7-14] The following definitions apply:

a. Hazardous material is any article or substance designated by the U.S. Department of Transportation (DOT) as being capable of posing an unreasonable risk to health, safety, and property during transportation. In international commerce, hazardous materials are known as “dangerous goods.”

b. Limited quantity is the maximum amount of a specific hazardous material that is exempted from the labeling or packaging requirements in 49 CFR. Not every hazardous material is eligible to be shipped as a limited quantity. Almost all limited quantity materials are nonmailable.

c. ORM-D (Other Regulated Material) material is a limited quantity of a hazardous material that presents a limited hazard during transportation due to its form, quantity, and packaging. Not all hazardous materials permitted to be shipped as a limited quantity can qualify as an ORM-D material. The ORM-D category is only applicable for materials intended for ground transportation. Effective January 1, 2021, the ORM-D category will be eliminated for materials intended for surface transportation. After this date, the mailability of materials previously fitting the description of ORM-D must be evaluated based on its eligibility under the applicable consumer commodity or mailable limited quantity categories.

d. Consumer commodity is a hazardous material that is packaged and distributed in a quantity and form intended or suitable for retail sale and designed for consumption by individuals for their personal care or household use purposes. This term can also include certain drugs or medicines. Not all hazardous material permitted to be shipped as a limited quantity can qualify as a consumer commodity. The consumer commodity category will not apply to materials, intended for air transportation, in hazard classes 4, 5, and 8, and portions of hazard Class 9.

e. Mailable Limited Quantity is a hazardous material in hazard Classes 4, 5, 8 or portions of 9 that presents a limited hazard during transportation (specifically air transport), and is mailable in USPS air networks under certain conditions and in limited quantities.

f. Air transportation requirements, for the purposes of 10.0 only, apply to all mailable hazardous materials sent at the First-Class Mail, Priority Mail, or Priority Mail Express prices. All mailable hazardous materials sent at those prices must meet the requirements that apply to air transportation. Mailable hazardous materials sent at any of those prices may or may not be transported via air depending on the distance between the point of origination and the point of destination, and the ability of the USPS to obtain an air carrier between those points.

g. Surface transportation requirements, for the purposes of 10.0 only, apply to all mailable hazardous materials sent at the Standard Mail or Package Services prices. All mailable hazardous materials sent at the Standard Mail or Package Services prices must meet the requirements that apply to surface transportation.

h. Primary receptacle is the container (e.g., tube, vial, bottle) that holds the hazardous material.

i. Secondary container is the packaging component into which the primary receptacle(s) and any required absorbent and cushioning material is securely placed. The packaging of certain mailable hazardous materials does not require the use of a secondary container.

j. Outer shipping container is the exterior packaging component into which a primary receptacle, along with any required absorbent and cushioning material, and the secondary container (if required) are securely placed. The outer shipping container bears the addressing information along with all required markings.

10.2 U.S. Department of Transportation Regulations of Hazardous Material

The U.S. Department of Transportation (DOT) regulates the surface and air carriage of hazardous materials within the United States via any means of transportation. The DOT regulations for the transport of hazardous materials are codified in Title 49, Code of Federal Regulations (49 CFR) 100–185. USPS mailing standards for hazardous materials generally adhere to 49 CFR, but also include many additional limitations and prohibitions.

10.3 USPS Standards for Hazardous Material

[4-7-14] The USPS standards generally restrict the mailing of hazardous materials to ORM-D (category and marking permitted for surface transportation only until December 31, 2020), and consumer commodity or mailable limited quantity materials that meet USPS quantity limitations and packaging requirements. All exceptions are subject to the standards in 10.0. Detailed information on the mailability of specific hazardous materials is contained in Publication 52, Hazardous, Restricted, and Perishable Mail.

10.4 Hazard Class

Every hazardous material is assigned to one of nine hazard classes identified in 49 CFR 172.101 and 173. Some hazard classes are further separated into divisions based on their physical or chemical properties. For postal purposes, Exhibit 10.4 generally summarizes the mailability of hazardous materials by hazard class.

10.5 Mailer Responsibility for Mailing Hazardous Materials

Full responsibility rests with the mailer to comply with all postal and nonpostal laws and regulations regarding the mailing of hazardous materials. Anyone who mails, or causes to be mailed, a nonmailable or improperly packaged hazardous material can be subject to legal penalties, including but not limited to those specified in 18 USC.

10.6 Mailability Rulings for Hazardous Materials

Generally, the acceptability for mailing chemicals and other types of hazardous materials depends on container fluid/vapor capacities, the ability of the complete mailpiece to contain the material, and the method of absorbing and containing the product in case of accidental leakage of the primary receptacle. To determine mailability of a specific material, a mailer must submit a material safety data sheet (MSDS) and the following information to the Pricing and Classification Service Center (PCSC):

a. Name of material, hazard class, and assigned United Nations (UN) or North America (NA) identification number.

b. Chemical composition by percentage of ingredient.

c. Flashpoint.

d. Toxic properties.

e. Irritant action when inhaled, swallowed, or contacted by eyes or skin.

f. Special precautions necessary to permit handling without harm to USPS employees or damage to property or other mail.

g. Explanation of warning labels and shipping papers required by state or federal regulations.

h. Proposed packaging method, including the addressing and required markings.

i. Proposed number of pieces to be mailed, class of mail, and Post Office(s) of mailing.

10.7 Warning Labels for Hazardous Materials

[4-7-14] With few exceptions as noted in these standards, most hazardous materials acceptable for mailing fall within the current Other Regulated Materials (ORM-D) regulations of 49 CFR 173.144 for materials intended for surface transportation, and the consumer commodity or mailable limited quantity categories for materials intended for air transportation. Mailpieces containing mailable hazardous materials intended for transportation by air are required to bear an approved DOT square-on-point marking under 10.8b. and may also be required to bear a specific DOT hazardous material warning label (if required for the hazard class shipped). Mailpieces containing mailable hazardous materials must be marked as required in 10.8 and must bear DOT handling labels (e.g., orientation arrows, magnetized materials) when applicable. Effective January 1, 2021, the ORM-D category will be eliminated for materials intended for surface transportation, and mailpieces containing hazardous materials intended for surface transportation will be required to be marked using the appropriate DOT square-on-point marking. Also after this date, the mailability of materials previously fitting the description of ORM-D must be evaluated based on its eligibility under the applicable consumer commodity or mailable limited quantity categories.

10.8 Package Markings for Hazardous Materials

[4-7-14] Unless otherwise noted, each mailpiece containing a mailable hazardous material must be plainly and durably marked on the address side with the required shipping name and UN identification number. Mailpieces containing mailable air-eligible hazardous materials intended for air transportation must bear a DOT limited quantity square-on-point marking under 10.8b.. Mailpieces containing mailable hazardous materials intended for surface transportation may be entered and marked under the ORM-D category before January 1, 2021. After this date, all parcels containing mailable hazardous materials must bear the appropriate DOT square-on-point marking and other associated markings when required. The following also applies:

a. The use of DOT limited quantity square-on-point markings are currently required for mailpieces intended for air transportation and are optional (until December 31, 2020) for mailpieces intended for surface transportation (see Exhibit 10.8b). The plain square-on-point marking is used for shipments sent by surface transportation, and the square-on-point marking including the symbol “Y” superimposed in the center is used for shipments sent by air transportation. The following also applies:

1. Markings must be durable, legible and readily visible.

2. The marking must be applied on at least one side or one end of the outer packaging. The border forming the square-on-point must be at least 2 mm (0.08 inch) in width and the minimum dimension of each side must be 100 mm (3.94 inches), unless the package size requires a reduced size marking of no less than 50 mm (1.97 inches) on each side.

3. For surface transportation, the top and bottom portions of the square-on-point and the border forming the square-on-point must be black and the center must be white or of a suitable contrasting background. Surface shipments containing qualifying ORM-D materials and bearing the square-on-point limited quantity marking are not required to be marked with the shipping name and identification number.

4. For transportation by aircraft, the top and bottom portions of the square-on-point and the border forming the square-on-point must be black and the center must be white or of a suitable contrasting background. The symbol ‘‘Y’’ must be black and located in the center of the square-on-point and be clearly visible. Mailpieces intended for transport by air must also be marked with the proper shipping name, identification number, and must also display the appropriate DOT hazardous material warning label (only when required for the hazard class shipped) in accordance with Publication 52.

a. Authorization. Each vendor of a complete regulated medical waste or sharps waste mailing container system (including all component parts required to safely mail such waste to a storage or disposal facility) must obtain authorization from the USPS prior to mailing. Before applying for authorization, each type of mailing container system must be tested and certified under the standards in 10.17.5e by an independent testing facility. The vendor in whose name the authorization is being sought must submit a written request to the manager, Product Classification, USPS Headquarters (see 608.8.0, for address). The request for authorization must contain the following:

1. An irrevocable $50,000 surety bond or letter of credit as proof of sufficient financial responsibility to cover disposal costs if the vendor ceases doing business before all its waste container systems are disposed of or to cover cleanup costs if spills occur while the containers are in USPS possession. The surety bond or letter of credit must be issued in the name of the vendor seeking the authorization and must name the USPS as the beneficiary or obligee. Vendors that market their containers to distributors are responsible for disposal and cleanup costs attributed to those containers. In addition, vendors must provide a list of distributors, including firm names, addresses, and telephone numbers, to the Postal Service on request.

2. Address of the headquarters or general business office of the vendor seeking the authorization.

3. Name, address, and phone number of each storage and disposal site.

f. Testing Criteria. Packages tested for approval as Medical Professional Packages may not be tested using pre-primary containers that are currently, or have previously been, approved as USPS primary containers. Test reports must identify by brand name the pre-primary containers used during testing. Each mailpiece must pass each of the tests described below:

1. Leak-proof test. The test must be conducted on one primary receptacle with the lid in place, without the secondary and outer packaging. The test duration must be at least 5 minutes and must be conducted at 20 kPa (3 psi). The pass/fail criterion is: no air leakage from anywhere other than the closure of the primary receptacle. Air leakage at the closure is not considered a failure if the primary receptacle passes the test for watertightness as determined by placing 50 ml of deionized water into the primary receptacle, securing the closure, and then turning the container on its side and observing for any evidence of leakage. Any evidence of water leaking from the primary receptacle is a failure.

2. Stacking test. One mailpiece must withstand the test in 49 CFR 178.606. The dynamic compression test must be conducted on the empty, unsealed mailpiece assembled for mailing, without the primary receptacle(s). The test mass is the vendor-identified maximum weight, not to exceed 25 pounds, as indicated on the outer shipping container and on the assembly and closing instructions. A compensation factor of 1.5 must be used to compute the test load, based on the vendor-identified weight. The pass/fail criteria are: no buckling of the sidewalls sufficient to cause damage to the contents in the primary receptacle, and in no case does the deflection exceed 1 inch.

3. Vibration test. One mailpiece filled with sharps or other regulated medical waste must withstand the test in 49 CFR 178.608. The test mailpiece is filled with sharps or other regulated medical waste to the vendor-identified maximum weight, not to exceed 25 pounds, as indicated on the outer shipping container and on the assembly and closing instructions. The test sample is prepared as it would be for mailing. The pass/fail criterion is: no rupture, cracking, or splitting of any primary receptacle.

4. Wet drop test. Five mailpieces filled with sharps or other regulated medical waste must withstand the test in 49 CFR 178.609e. Each test mailpiece is filled with sharps or other regulated medical waste to the vendor-identified maximum weight, not to exceed 25 pounds, as indicated on the outer shipping container and on the assembly and closing instructions included with each mailpiece. Each mailpiece is prepared as it would be for mailing and subjected to a water spray as described in the test. A separate, untested mailpiece is used for each drop orientation: top, longest side, shortest side, and corner. The pass/fail criteria are: no rupture, cracking, or splitting of any primary receptacle, and no contents may penetrate into or through the body or lid of any primary receptacle.

5. Cold drop test. Five mailpieces filled with sharps or other regulated medical waste must withstand the test in 49 CFR 178.609f. Each test mailpiece is filled with sharps or other regulated medical waste to the vendor-identified maximum weight, not to exceed 25 pounds, as indicated on the outer shipping container and on the assembly and closing instructions included with each mailpiece. Each mailpiece is prepared as it would be for mailing and chilled as described in the test. A separate, untested mailpiece is used for each drop orientation: top, longest side, shortest side, and corner. The pass/fail criteria are: no rupture, cracking, or splitting of any primary receptacle, and no contents may penetrate into or through the body or lid of any primary receptacle.

6. Impact test. One mailpiece filled with sharps or other regulated medical waste must withstand the test in 49 CFR 178.609h. The test mailpiece is filled with sharps or other regulated medical waste to the vendor-identified maximum weight, not to exceed 25 pounds, as indicated on the outer shipping container and on the assembly and closing instructions included with each mailpiece. The mailpiece is prepared as it would be for mailing. The pass/fail criteria are: no rupture, cracking, or splitting of any primary receptacle, and no contents may penetrate into or through the body or lid of any primary receptacle.

7. Puncture-resistant test. Package testing results must show that during all of the previous tests, the contents did not penetrate through the primary receptacle.

8. Temperature test. Package testing results must show that each primary receptacle maintained its integrity when exposed to temperatures as low as 0°F and as high as 120°F.

9. Absorbency test. Package testing results must show that the primary receptacle(s) contain enough absorbent material to absorb three times the total liquid allowed within the primary receptacle in case of leakage. Absorbency is determined by pouring 150 ml of deionized water into the primary receptacle(s), then turning the receptacle(s) upside down and observing for any evidence of free liquid not absorbed on contact. Any evidence of free liquid is a failure.

10. Watertight test. Package testing results must show that no leakage occurred when 50 ml of deionized water was placed into the secondary containment system and the entire system turned upside down for 5 minutes.

g. Suspension of Authorization. The Postal Service may suspend a vendor's authorization based on information that a mailpiece no longer meets the standards for mailing sharps medical waste and regulated medical waste containers, or that the mailpiece poses an unreasonable safety risk to Postal Service employees or the public. The suspension can be made immediately, making the mailpiece nonmailable immediately. The vendor may contest a decision to suspend authorization by writing to the manager, Product Classification (see 608.8.0 for address), within 7 days from the date of the letter of suspension. The appeal should provide evidence demonstrating why the decision should be reconsidered. Any order suspending authorization remains in effect during an appeal or other challenge. When a vendor is notified that its authorization to mail sharps or other regulated medical waste containers has been suspended, the vendor must immediately:

1. Recall all identified containers.

2. Notify all customers that they cannot mail the identified containers.

3. Suspend sales and distribution of all identified containers.

4. Collect the identified containers from distributors, consumers, and the Postal Service without using the mail and in accordance with all federal and state regulations.

11.1 Definitions

For this standard, we define terms as follows:

a. Cigarette: any roll of tobacco wrapped in paper or in any substance not containing tobacco and any roll of tobacco wrapped in any substance containing tobacco which, because of its appearance, the type of tobacco used in the filler, or its packaging and labeling, is likely to be offered to, or purchased by, consumers as a cigarette. The term cigarette includes roll-your-own-tobacco and excludes cigars.

b. Smokeless tobacco: any finely cut, ground, powdered, or leaf tobacco that is intended to be placed in the oral or nasal cavity or otherwise consumed without being combusted.

c. Cigar: any roll of tobacco wrapped in leaf tobacco or in any substance containing tobacco, unless, because of its appearance, the type of tobacco used in the filler, or its packaging and labeling, the product is likely to be offered to, or purchased by, consumers as a cigarette.

d. Roll-your-own tobacco: any tobacco which, because of its appearance, type, packaging, or labeling, is suitable for use and likely to be offered to, or purchased by, consumers as tobacco for making cigarettes or cigars, or for use as wrappers thereof.

e. Consumer testing: testing limited to formal data collection and analysis for the specific purpose of evaluating the product for quality assurance and benchmarking purposes of cigarette brands or sub-brands among existing adult smokers.

f. State: any of the 50 states of the United States, the District of Columbia, and any commonwealth, territory, or possession of the United States.

11.2 Nonmailability

13.0 Written, Printed, and Graphic Matter Generally

13.1 Solicitations in Guise of Bills, Invoices, or Statements of Account (39 USC 3001(D); 39 USC 3005)

13.1.1 General

Any otherwise mailable matter that reasonably could be considered a bill, invoice, or statement of account due, but is in fact a solicitation for an order, is nonmailable unless it conforms to 13.1.2 through 13.1.5. A nonconforming solicitation constitutes prima facie evidence of violation of 39 USC 3005. Compliance with this section does not avoid violation of Section 3005 if any part of the solicitation or any information with it misrepresents a material fact to the addressee (e.g., misleading the addressee about the identity of the sender of the solicitation or about the nature or extent of the goods or services offered may be a violation of Section 3005).

13.1.2 Required Disclaimer

The solicitation must bear on its face either the disclaimer required by 39 USC 3001(d)(2)(A) or the notice: “THIS IS NOT A BILL. THIS IS A SOLICITATION. YOU ARE UNDER NO OBLIGATION TO PAY THE AMOUNT STATED ABOVE UNLESS YOU ACCEPT THIS OFFER.” The statutory disclaimer or the alternative notice must be displayed in conspicuous boldface capital letters of a color prominently contrasting with the background against which it appears, including all other print on the face of the solicitation and that are at least as large, bold, and conspicuous as any other print on the face of the solicitation, but not smaller than 30-point type (see Exhibit 13.1.2). The notice or disclaimer required by this section must be displayed conspicuously apart from other print on the page immediately below each portion of the solicitation that reasonably could be construed to specify a monetary amount due and payable by the recipient. It must not be preceded, followed, or surrounded by words, symbols, or other matter that reduces its conspicuousness or that introduces, modifies, qualifies, or explains the required text, such as “Legal Notice Required by Law.”

Exhibit 13.1.2 Solicitation Disclaimer

Shows the required disclaimer for written, printed, and graphic matter.

13.1.3 Intelligibility

The notice or disclaimer must not, by folding or any other device, be made unintelligible or less prominent than any other information on the face of the solicitation.

13.1.4 Separable Pages

If a solicitation consists of more than one page or if any page is designed to be separated into portions (e.g., by tearing along a perforated line), the notice or disclaimer required by 13.1.2 must be displayed in its entirety on the face of each page or portion of a page that might be reasonably considered a bill, invoice, or statement of account due as required by 13.1.2.

13.1.5 Definitions

For this standard, color prominently contrasting excludes any color, or any intensity of an otherwise included color, that does not permit legible reproduction by ordinary office photocopying equipment used under normal operating conditions, and which is not at least as vivid as any other color on the face of the solicitation; and color includes black.

13.2 Solicitations Deceptively Implying Federal Connection, Approval, or Endorsement (39 USC 3001(H) and 3001(I); 39USC3005)

13.2.1 USPS Endorsement

Any solicitation stating that it is approved by the USPS or the Postmaster General or that it conforms to any postal law or regulation is nonmailable.

13.2.2 Nonmailable by Government Misrepresentation

A solicitation that misrepresents a government entity is nonmailable subject to these conditions:

a. Matter that contains a solicitation for products, services, information, or funds that implies any federal government connection, approval, or endorsement through the use of a seal, insignia, reference to the Postmaster General, citation to a federal statute, name of a federal agency, department, or commission, or program, trade, or brand name, or any other term or symbol; or contains any reference to the Postmaster General or a citation to a federal statute that misrepresents either the identity of the mailer or the protection or status afforded such matter by the federal government is nonmailable unless it conforms to 13.2.3. A nonconforming solicitation constitutes prima facie evidence of violation of 39 USC 3005. Compliance with 13.2.3 does not avoid violation of 39 USC 3005 if the solicitation or accompanying information misrepresents material fact such as the nature, value, quantity, quality, or efficacy of the products or services offered for sale, or of the activities of an organization asking for information or monetary contributions.

b. Such solicitations must not contain a false representation that federal government benefits or services will be affected by whether or not the recipient makes a purchase or contribution.

c. Solicitations for payment for services otherwise available to the recipient free of charge from the federal government are nonmailable unless they contain a clear and conspicuous statement giving notice of that fact.

13.2.3 Permitted Solicitations

A solicitation described in 13.2.2a may be mailable if it meets at least one of these conditions (see Exhibit 13.2.3b):

a. The solicitation is by a nongovernmental entity that actually has the federal government connection, approval, or endorsement implied by the solicitation’s terms or symbols.

b. The solicitation appears in a publication for which the addressee has paid or promised to pay a consideration or which the addressee has otherwise indicated he or she wants to receive, and the solicitation is not on behalf of the publisher of the publication.

The letters for printing these notices must be as large, bold, and conspicuous as any other letters on the face of the solicitation, but never smaller than 30-point type. The notice must be surrounded by a clear space at least 1/2 inch wide.
