[1-4-10] Except under 1.3, 1.4, and 1.5, Priority Mail retail prices are charged per pound; any fraction of a pound is rounded up to the next whole pound. For example, if a piece weighs 1.2 pounds, the weight (postage) increment is 2 pounds. The minimum postage amount per addressed piece is the 1-pound price. Priority Mail retail prices are based on weight and zone except for Flat Rate products. Other charges may apply.
[1-4-10] See Notice 123—Price List for applicable Priority Mail retail prices.
Parcels addressed for delivery to Zones 1-4 (including Local) that weigh less than 20 pounds but measure more than 84 inches (but not more than 108 inches) in combined length and girth are charged the applicable zone price for a 20-pound parcel (balloon price).
Postage for parcels addressed for delivery to Zones 5-8 and exceeding 1 cubic foot (1,728 cubic inches) is based on the actual weight or the dimensional weight (as calculated in 1.4.1 or 1.4.2), whichever is greater.
a. Measure the length, width, and height in inches. Round off (see 604.7.0) each measurement to the nearest whole inch.
c. If the result exceeds 1,728 cubic inches, divide the result by 194 and round up (see 604.7.0) to the next whole number to determine the dimensional weight in pounds.
a. Measure the length, width, and height in inches at their extreme dimensions. Round off (see 604.7.0) each measurement to the nearest whole inch.
d. If the final result exceeds 1,728 cubic inches, divide the result by 194 and round up (see 604.7.0) to the next whole number to determine the dimensional weight in pounds.
Any amount of material may be mailed in a USPS-produced Priority Mail Flat Rate Box or Flat Rate Envelope. When sealing a Flat Rate Box or Flat Rate Envelope, the container flaps must be able to close within the normal folds. Tape may be applied to the flaps and seams to reinforce the container, provided the design of the container is not enlarged by opening the sides and the container is not reconstructed in any way.
[1-4-10] Each USPS-produced Priority Mail Flat Rate Envelope is charged a flat rate regardless of the actual weight (up to 70 pounds) of the mailpiece or domestic destination. Only USPS-produced Flat Rate Envelopes are eligible for the Flat Rate Envelope price.
[1-4-10] For shipping convenience, there are multiple Priority Mail Flat Rate Boxes as follows: Small Flat Rate Box to domestic, APO/FPO, and DPO destinations; Medium Flat Rate Boxes (FRB-1) or (FRB-2) to domestic, APO/FPO, and DPO destinations; Large Flat Rate Box or "special version of this box" to APO/FPO and DPO destinations; and large Flat Rate Box to domestic destinations only. The large Flat Rate Box to APO/FPO and DPO destinations or "special version of this box" is priced less than the conventional domestic large Flat Rate Box. Items sent to APO/FPO and DPO destination addresses may be shipped in the Priority Mail large Flat Rate Box or in a special version of the box identified with the additional logo: "Americasupportsyou.mil." If the special version of the APO/FPO Flat Rate Box is used for non-APO/FPO and DPO destination addresses, the domestic or international large Flat Rate Box prices will apply. Only USPS-produced Flat Rate Boxes are eligible for the Flat Rate Box prices. Each USPS-produced Priority Mail Flat Rate Box is charged a flat rate regardless of the actual weight (up to 70 pounds) of the mailpiece or domestic destination. See Notice 123—Price List for applicable prices.

Keys and identification devices weighing more than 1 pound but not more than 2 pounds are mailed at the 2-pound Priority Mail price for zone 4 plus the fee. The key or identification device must bear, contain, or have securely attached the name and complete address of a person, organization, or concern, with instructions to return the key or identification device to that address and a statement guaranteeing payment of postage due on delivery.

To determine single-piece weight in any mailing of nonidentical-weight pieces, weigh each piece individually. To determine single-piece weight in a mailing of identical-weight pieces, weigh a sample group of at least 10 randomly selected pieces and divide the total sample weight by the number of pieces in the sample. Express all single-piece weights in decimal pounds rounded off to four decimal places.
Determine single-piece weight increment for each piece and affix postage to each piece under 124.1.2, Affixing Postage—Single-Piece Mailings (as applicable) or, for permit imprint mailings, multiply the number of addressed pieces at each price increment by the corresponding postage price.
[11-29-09] Priority Mail is an expedited service and may contain any mailable matter weighing no more than 70 pounds except for APO and FPO mail subject to 703.2.0, Overseas Military Mail, 703.4.0, Mail Sent by U.S. Armed Forces, and Department of State mail subject to 703.3.0.
All Priority Mail receives expeditious handling and transportation. The USPS follows uniform guidelines for distributing and delivering mail but does not guarantee delivery within the specified time. Local postmasters can provide more information.
Matter closed against postal inspection includes First-Class Mail, Priority Mail, and Express Mail. The USPS may open mail other than First-Class Mail, Priority Mail or Express Mail to determine whether the proper postage is paid. Material wrapped or packaged so that it cannot be examined easily or examined without destruction or serious damage is closed against postal inspection and is charged the appropriate First-Class Mail, Priority Mail, or Express Mail price.
Unless Express Mail is used, Priority Mail prices are required for a mailpiece that weighs more than 13 ounces when the mailpiece contains matter that must be mailed as First-Class Mail. Complete descriptions of matter requiring the use of First-Class Mail are provided in 133.3.0.
