The PS 2976 Forms are a set of six documents released by the United States Postal Service (USPS) and used with international shipments. These forms are:
Customs forms are necessary for all international shipments and for all parcels sent to an Army Post Office (APO), a Fleet Post Office (FPO), and for Diplomatic Post Office (DPO) destinations. These forms are a summary of the contents of the shipment, the information about the sender and the addressee. This information is necessary for the border control inspection at the border of the accepting country. The preparation of the customs form is the responsibility of the sender.
The USPS releases several customs forms: the appropriate form (except for the PS Form 2976-R) is determined by the mailing service the sender is using:
Each of these forms requires preparing three copies. The first copy is for the sender, the second is prepared for customs and the third copy should be kept at the post office for 30 days.
PS Form 2976-R serves as a worksheet, that the sender can obtain and fill only at the post office. The information from this form is entered into the retail system or Customs Forms Online and then the appropriate form is generated and affixed to the parcel. The PS 2976-R cannot be used as a stand-alone customs form. PS Form 2976-E and PS Form 2976-ES are envelopes, made of transparent plastic. They are designed to contain the customs forms and other necessary papers and protect them. The difference between the two forms is the size. The PS 2976-ES is a smaller envelope, designed for small parcels, for which the PS 2976-E does not fit.
All customs forms (except for the PS 2976-R) can be filled online. The USPS website offers the Click-N-Ship tool, that generates the completed appropriate customs form after entering all necessary data.
