When to complete a CN22 customs form

The CN22 is a customs form used when sending gifts and goods abroad worth less than £270 with Royal Mail.

CN22 form guide

Custom forms are mandatory for all gifts and goods sent outside the UK from England, Scotland or Wales. If posting from Northern Ireland, they're only needed for non-EU destinations, except the UK.

If you have a printer, you can complete this form online or download a blank copy to fill in by hand before you visit a branch. If you don't have a printer, you can pick one up in branch.

Customs forms are scanned by optical character recognition, so it's important to fill them in legibly and in BLOCK CAPITALS.

Incomplete or missing customs forms are likely to result in items being returned to the sender.

Example of the CN22 form
  1. Sender's name and address are mandatory – include your full name and address including postcode 
  2. Content type and description of contents are mandatory – include an accurate description of each item enclosed. This will help to avoid delays or customs officials needing to open your item 
  3. Value, quantity and weight of each item are mandatory 
  4. Total quantity is mandatory – add the total number of items within your package 
  5. Total weight is mandatory – this is the total weight of your item. If you don’t know and can’t easily find out, weigh your package and complete in branch

  7. HS tariff number – is mandatory for businesses only – you need to provide the HS tariff code which you can find at GOV.UK

Common questions about customs forms

    They help local customs authorities identify if items you’re sending internationally are allowed into their destination country and calculate any duties or taxes due.

    Incomplete or missing customs forms are likely to result in items being returned to the sender.
