Priority Mail International service is governed by the provisions of the Universal Postal Union (UPU) Postal Parcels Agreement. Priority Mail International service is designed to accommodate larger and heavier shipments whose size and/or weight exceed the established limitations for First–Class Mail International items.
The maximum weight limit for Priority Mail International parcels varies by country, ranging from 22 pounds to 70 pounds. See IMM 230 and the Individual Country Listings in the IMM for maximum weight limits. Customers who pay for Priority Mail International postage online through Click-N-Ship or through an authorized PC Postage vendor will pay 5 percent less than retail postage prices. Commercial base prices are also available for postage paid through a permit imprint advance deposit account. See IMM 230 or your local Post Office for details.
Table 3a contains the postage prices for Priority Mail International parcels. See the “Priority Price Group” column in the Country Listing for the specific price groups that are applicable to each destination country.
