123 Rates and Eligibility

1.0 Priority Mail Rates and Fees

1.1 Application

Priority Mail rates apply to pieces meeting the standards in 123.

1.2 Priority Mail Rate Application

Except under 1.6, Flat-Rate Envelope, Priority Mail rates are charged per pound or fraction thereof; 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 rate. The Priority Mail rate up to 1 pound is based solely on weight; for pieces weighing more than 1 pound, rates are based on weight and zone.

1.3 Priority Mail Rates

Parcels that weigh less than 15 pounds but measure more than 84 inches in combined length and girth are charged the applicable rate for a 15-pound parcel. The 1-pound rate is charged for matter sent in a Priority Mail flat-rate envelope provided by the USPS, regardless of the actual weight of the piece. See Exhibit 1.3, Priority Mail Rates.

1.9 Determining Single-Piece Weight

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.

1.10 Computing Postage—Priority Mail

Determine single-piece weight increment for each piece and affix postage to each piece under 124.1.2, Affixing Postage—Single-Piece Rate Mailings (as applicable) or, for permit imprint mailings, multiply the number of addressed pieces at each rate increment by the corresponding postage rate.

2.0 Basic Eligibility Standards for Priority Mail

2.1 Definition of Priority Mail

Priority Mail is First-Class Mail weighing more than 13 ounces and, at the mailer's option, any other mailable matter weighing 13 ounces or less. Priority Mail rates are based on zone and weight. The maximum weight is 70 pounds, except for APO and FPO mail subject to 703.2.0, Overseas Military Mail, and 703.4.0, Mail Sent by U.S. Armed Forces, and Department of State mail subject to 703.3.0.

2.2 Service Objectives

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.

2.3 Matter Closed Against Postal Inspection

Matter closed against postal inspection includes First-Class Mail (including Priority Mail) and Express Mail. The USPS may open mail other than First-Class Mail or Express Mail to determine whether the proper rate of 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 or Express Mail rate.

Complete descriptions of matter requiring the use of First-Class Mail are provided in 133.3.0.
