USPS Customs Forms

What Are USPS® Customs Forms?

U.S. Postal Service® mail headed to an international destination or sent via Military Mail and weighing more than 16 ounces requires the use of a customs form. Customs forms summarize the contents of the package and identify the value of the shipped items. These forms make it possible for the destination country to examine mail and allow its entry without having to open and inspect each item one-by-one.

The USPS has two different types of customs forms for international mail: PS Form 2976 and PS Form 2976-A. The weight, value, mail class and destination of the package determine which form to use. If you are a customer, the software will automatically determine the appropriate form.
