The CN22 is a customs form used when sending gifts and goods abroad worth less than £270 with Royal Mail.
They are mandatory for all gifts and goods being sent internationally from England, Scotland or Wales anywhere outside the UK, if posting from Northern Ireland they are only needed for posting to non-EU destinations.
If sending items with Royal Mail International Economy and International Standard – you’ll need a CN22B (with a barcode) available in all Post Office branches.
If sending items with Royal Mail International Tracking and Signature services – you’ll need a CN22A. These are available in branch, but you can also complete online or download a blank copy to fill before you visit.
Incomplete or absent customs forms are likely to result in items being returned to the sender.
The forms are scanned by optical character recognition, so it is important to fill them in legibly and in BLOCK CAPITALS.
