Except for Flat Rate Packaging (see 1.4), Priority Mail Express postage is charged for each addressed piece according to its weight and zone. The 0.5-pound price is charged for items up to 0.5 pound and items over 0.50 pound are rounded up to the next whole pound. For example, if a piece weighs 0.25 pound, the weight (postage) increment is 0.50 pound. Express all weights in decimal pounds rounded off to two decimal places.
See Notice 123—Price List for applicable Priority Mail Express retail prices.
Postage for parcels addressed for delivery to Zones 1-9 and exceeding 1 cubic foot (1,728 cubic inches) is based on the actual weight or the dimensional weight (as calculated in 1.3.1 or 1.3.2), whichever is greater.
Follow these steps to determine the dimensional weight for a rectangular parcel:
- Measure the length, width, and height in inches. Round off (see 604.7.0) each measurement to the nearest whole inch.
- Multiply the length by the width by the height.
- If the result exceeds 1,728 cubic inches, divide the result by 166 and round up (see 604.7.0) to the next whole number to determine the dimensional weight in pounds.
- If the dimensional weight exceeds 70 pounds, the customer pays the 70-pound price.
Follow these steps to determine the dimensional weight for a nonrectangular parcel:
- 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.
- Multiply the length by the width by the height.
- Multiply the result by an adjustment factor of 0.785.
- If the final result exceeds 1,728 cubic inches, divide the result by 166 and round up (see 604.7.0) to the next whole number to determine the dimensional weight in pounds.
- If the dimensional weight exceeds 70 pounds, the customer pays the 70-pound price.
Only USPS-produced Flat Rate Envelopes are eligible for the Flat Rate price and are charged a flat rate, regardless of the actual weight (up to 70 pounds) of the mailpiece or domestic destination. Customers must only use USPS-produced Flat Rate Envelopes at the applicable Flat Rate Envelope price. USPS-produced packaging, including Flat Rate containers, is not eligible for shipping live animals.
Delivery guaranteed for a Sunday or holiday is charged a premium fee (see Notice 123—Price List), unless paying via a Priority Mail Express Manifesting Agreement. Customers not desiring delivery on a Sunday or a holiday may avoid the premium by opting for guaranteed delivery on the subsequent delivery day.
A Priority Mail Express piece is subject to the nonstandard fees (see Notice 123—Price List) as follows:
- A piece measures more than 22 inches up to 30 inches long.
- A piece measures more than 30 inches long.
- A piece measures more than 2 cubic feet (3,456 cubic inches). Dimensions for rectangular pieces are determined by measuring the length, width, and height in inches, rounding off (see 604.7.0) each measurement to the nearest whole inch and multiplying the length by the width by the height. Dimensions for nonrectangular pieces are calculated as above and the result multiplied by an adjustment factor of 0.785. If either calculation exceeds 3,456 cubic inches, the piece is subject to the nonstandard fee.
- A piece may be subject to both a length (1.6a, 1.6b) and a cube (1.6c) nonstandard fee.
