USPS® Delivered Duty Paid (DDP) Service
Effective January 18, 2026, the Postal Service is introducing the USPS Delivered Duty-Paid (DDP) fee. DDP involves the mailer prepaying any required applicable customs duties, taxes, and fees on items mailed from certain U.S. possessions and territories and destined to domestic locations within the U.S. customs territory. The fee that the Postal Service will establish for facilitating payment does not include any other applicable taxes and duties, or any non-USPS fees, which are collected separately and passed through to a third party.
The Postal Service provides additional resources to assist customers with this price change for competitive products. These tools include price lists, downloadable price files, and Federal Register Notices, which are available on the Postal Explorer website at pe.usps.com.
