What USPS Customs form is required for my international shipment?

The Create a USPS Shipment API automatically provides the correct USPS Customs form based on the information included in the label request. The API provides forms for the services listed in the table below. The returned form is used as both the shipping label and the Customs declaration.

A form can be single-ply or multi-ply. Single-ply forms can be attached directly to the parcel. Multi-ply forms require a USPS Customs pouch to hold three copies of the form: two copies labeled “Customs Declaration” and one labeled “Dispatch Note.” For each type of form, the API prints one or more “Continuation Pages” if the shipment contains more items than can be listed in the “Detailed Description of Contents” on the original form.

Customs forms use the DOC_4X6 and DOC_8X11 label sizes, as set in the documents.size field.

The API supports Customs forms for the following services:

Service Form Number Form Name Additional Information
First-Class Mail International (FCMI), or
First-Class Package International Service (FCPIS)
PS Form 2976 Customs Declaration CN 22 – Sender’s Declaration

This is a single-ply form and can be attached directly to the parcel without a Customs pouch.

For FCMI and FCPIS, the declared value for Customs cannot exceed $400.
