What is a CN23?

A Customs Declaration (CN23) is a customs document, used during international trade activities when goods are being transported overseas. It contains information about:
• The nature of the goods (including a detailed description and value)
• The country of origin.
• The Customs tariff number (if known)

When is a CN23 Customs Declaration used?

If your goods are being transported outside of the EU and have a value over £270 you must attach a signed and dated CN23. The document informs Customs of the contents of your consignment and helps them to check for banned or restricted items.

Why do I need a CN23 Customs Declaration?

You MUST have a Customs Declaration to send goods outside of the EU. If a declaration is not provided OR is completed incorrectly it can lead to delays or even seizure of the goods by Customs.
