Customs Forms for USPS | Overview

When you send an international shipment, customs forms are a requirement. Every country's border control agency uses customs forms to help protect their borders and to assign duty fees and tariffs on incoming goods. The recipient of the good(s) typically pays for any duty fees.

ShippingEasy Subscribers

Partners of USPS, including ShippingEasy, will automatically select the correct USPS customs form based on your selection of service and packaging. Learn more about ShippingEasy plans and features.

Once printed, attach the forms to the parcel or place them in an enclosed pouch and attach them to the outside of the box.

Some shipments will only require one copy of the customs form

Regardless of the form type, some shipments only require one copy of the customs form (combined into your shipping label).

These shipments include:

  • Military Mail (APO, DPO, FPO, MPO), US Territories, and the Freely Associated States

  • Select international destinations:

    • Australia

    • Canada

    • Costa Rica

US Postal Service Requirements

When you ship First Class International Mail to any destination or ship Priority Mail International to Military Mail and U.S. Territories, the total value of the shipment cannot be more than $400.

If your total value is over $400, you will see this alert on the READY TO SHIP page.

In this case, you would need to adjust the declared value of the Product's Details in your Inventory Management, or depending on the package details, you could split the order.

USPS International Shipping Update: HS Codes Required

As of September 1, 2025, the U.S. Postal Service will require all international commercial shipments to include a six-digit Harmonized System (HS) code on customs declarations for each item, regardless of mail class.

The HS code system, created by the World Customs Organization, is used by customs authorities worldwide to classify goods and assess tariffs. This update aligns USPS mailing standards with new Universal Postal Union (UPU) regulations, also taking effect Sept 1, requiring all member countries to enforce six-digit HS codes for commercial goods.

For a full list of Harmonization Codes, use the Harmonized Tariff Schedule search.

Retail | Post Office

Post Office customers will now use this downloadable customs information worksheet PS Form 2976-R. You can also obtain PS Form 2976-R at any post office. Once filled out, hand the form to the postal representative, who will print the appropriate electronic customs forms and barcodes.
