You don’t have time to figure out which complicated customs forms are
required for your international packages, let alone fill them out by hand.
And you don’t have to anymore. The next time you ship an International
package, let Endicia choose the correct customs form, pre-fill the
information, and print your declaration along with your postage on one
integrated label. All you need to do is declare the contents, for up to 30 different items.
For First-Class Mail International and the Priority Mail International flat rate envelope, you can print the integrated forms in a convenient, single-copy 4"x6" format. For other services, the correct number of copies will be printed on 8.5"x11" sheets to attach to your packages.

You can also print pre-filled customs forms for your military (APO/FPO) shipments. Even though you use domestic mail classes to send packages to these locations, they are still foreign destinations that require customs forms. Endicia takes care of that too – on standard 8.5"x11" sheets that you can attach to your packages, complete with round stamps and ready for pick-up.
Put International Mail at your fingertips – not a ball point pen.
