For mailings that are not containerized, the shipper must secure the mail to the pallet by shrink wrap prior to delivery to the carrier so that it will be secure, stable, and able to maintain unit integrity during transit.
All pallets must conform to DMM regulations. The overall dimensions of the palletized load may not exceed 40 inches x 48 inches x 77 inches (width x length x height). For compliance with postal safety requirements, the overall height must not exceed 77 inches including the pallet. The weight on a pallet should be uniformly distributed, with denser products on the bottom. The maximum weight of each pallet load is 2,500 pounds.
For each piece of mail on the pallet, the shipper must apply appropriate postage and must indicate the weight and addressee on the label. If more than one piece of mail is banded together, the shipper must attach a label to each piece so that the pieces, if they become separated, can still be identified and delivered. Parcels banded together are considered a single piece and must meet DMM requirements regarding the banding and strapping of parcels (see Addressing and Labeling).
Shippers should ensure that individual labels are turned to the inside of the banded unit so that the single piece address label is visible.
The weight of each shipment must be at least 1,000 pounds. If a shipment is less than the required weight, the Postal Service may consider it unacceptable for bypass acceptance. The shipper must enter the shipment at the appropriate postal facility to effect mailing.
