What is a customs form for?

When you send items internationally, you must make sure those items abide by the shipping rules of the destination country. Customs forms allow local customs authorities to make sure the goods are allowed and to calculate if there are any duties or taxes to be paid.

Customs forms need to be attached to the outside of your item with all relevant fields completed. You are responsible for ensuring a fully complete Customs Form is attached to your item. Any items with incomplete or absent customs forms are likely be returned to the sender so it's important you get it right.
