How USPS International Shipping Works

While private carriers like FedEx® and UPS® handle package delivery from the U.S. sender all the way to the international recipient, the USPS does things differently. The USPS delivers a package to customs in the destination country, at which point, the host postal service handles package delivery to the recipient. This means from the international customer’s perspective, the experience of receiving a package from the USPS is identical to the experience of receiving a domestic package. Additionally, the USPS sets itself apart from private carriers in the way it handles surcharges—it doesn’t have any! Private carriers charge additional fees like fuel and peak season surcharges on top of shipping rates, but with the USPS the rate you see is the rate you get.

Do I Need Custom Forms?

Customs forms are used to summarize the contents of your shipment and declare the value of the goods shipped. These forms allow customs officials to examine and approve packages without having to open and inspect each and every shipment. With the exception of envelopes weighing less than 16 ounces, all international shipments require customs forms.

Things to Consider Before Shipping Internationally

Product Restrictions

Product Restrictions

All countries prohibit or restrict certain products from entering their borders. These regulations are often due to cultural reasons, or to protect local industries. Before sending an international package be sure to research the destination county’s prohibited items list.

Customs Fees

Customs Fees

Customs fees are charged by the host country to control the flow of goods entering the country, especially on restrictive goods. These fees are put into place to cover the cost of a package going through the customs process.

Duties and Tariffs

Duties and Tariffs

Like customs fees, duties and tariffs are taxes applied to the value of an item, freight and insurance. Duties and tariffs are put into place to protect local industries within the host country. The final cost will vary depending on the type of good you send.



International taxes can be more complicated than taxes for domestic business. Taxes can be charged at the federal, provincial or city level.
