Customs forms are now mandatory if you were sending gifts or goods outside of the UK, except if posting to the EU from Northern Ireland.

They allow local customs authorities to make sure the goods are permitted and to calculate if there are any duties or taxes to be paid. Items with missing or incomplete are likely to be returned or delayed.

All customs forms are available in Post Office branches, but you can save time in branch by filling in some forms at home. CN22B have unique barcodes and and CP72 forms are multi-layered and therefore both are only available in branch – but you could pick up some spare forms the next time you visit.

Yes, we have blank CN22A customs form and CN23 customs form available to  download, print and fill in by hand.

Currently there are no declaration requirements for goods moved directly between Northern Ireland and the European Union, but customs forms are still needed if posting from Northern Ireland to non-EU destinations.
