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)

Do You Need A Certificate of Origin too?

In some rare cases, because of the CN23 containing the “country of origin” of the goods you are sending overseas, you may need to ask your buyer (or the ultimate receiver of your goods/consignment) if they need a Certificate of Origin, which basically identifies the country where the goods/consignment originated.  You buyer may need it to authenticate that the goods you’re sending genuinely come from the country you’ve stated.  Don’t just presume and get a Certificate of Origin (C/O), first ask your buyer if they need it and only then go to the trouble and expense of getting a C/O.

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.

How do I complete a CN23?

Simple!  Here’s a field-by-field guide to completing a CN23.  If the package or consignment is worth MORE THAN £270 (GBP) (or 270 Euros) then completing a CN23 is the simplest way to make a Customs Declaration (CN23).  This allows you to inform the Customs authorities on the content of your package and its nature/purpose, origin, value and if known the Customs Tariff (HS Code).   Here’s a field-by-field guide to completing a CN23.  There’s instruction on the back of the CN23, which you can follow to complete a CN23.  However, in this step-by-step guide, we’ve decided to use the 30 day-FREE trials version of the EdgeCTP application (i.e. it’s EdgeDOCS package) to help complete the CN23.

  • Is Package/Item for Commercial = Mandatory, indicate the purpose of the goods being sent are either for commercial or non-commercial usage/resell.  If it is for commercial, then you’ll need to also supply a Commercial (Export/Customs) Invoice with this CN23 declaration.  Learn how to create a commercial invoice if you don’t already have one.
  • Barcode = Optionally, add any Bar Codes that relate to the consignment or package that you are sending; this helps with tracking purposes.

  • Importer’s Reference and Contact Details = Optionally, provide these details to assist with ‘faster’ Customs clearance.

  • Attachment of Supporting Documents (i.e. Invoice) = Optional or Mandatory if goods are of a commercial nature, in which case you need to add a Commercial (Export/Customs) Invoice to clear Customs controls efficiently.  There is an option to electronically create a Commercial Invoice within EdgeDocs and attach it to the CN23, or simply add your own.  In either case, getting a physically print copy and attaching it to one side of the package is advisable
  • Attachment of Supporting Documents (i.e. Certificate) = Optional, and only if your buyer wants a Certificate of Origin or Movement Certificate for the goods you are sending, then go and get a certificate; otherwise, proceed WITHOUT one.  If you do get a certificate, then print + attach a copy to the package
