Customs forms

Customs forms are now mandatory for all gifts and goods sent to a country outside the UK, except when sending items from Northern Ireland to the EU.

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.

Do I need a customs form?

It is mandatory to complete a customs form if:
  • You are sending goods or gifts from England, Wales or Scotland to anywhere outside of the UK

  • You are sending goods or gifts from Northern Ireland to any non-EU destinations (except UK)

You don’t need to complete a customs form if:
  • You are sending goods within the UK

  • You are sending from Northern Ireland to EU destinations
  • You are sending letter or large letters only containing correspondence, commercial invoices or shipping documents

Sending internationally with Royal Mail

You need to make sure you use the right form as this varies based on the value of the item you are sending and the postage service you are using – all forms are available in all Post Offices, just ask at the counter for help.

Save time in branch! Some forms can be filled in online or you can download a blank form to fill in by hand. You’ll need access to printer so you can complete and attach the form before your branch visit.
