If you are sending international shipments with a goods total of £270 or less, you must attach a CN22 customs declaration with your regular shipping label. This document is used for customs clearance at the destination country.
Some international carriers provide paperless customs documents, which remove the requirement for you to complete a CN22 document. If you are not sure if your carrier offers this functionality, please get in touch with us or contact your carrier directly.
Shiptheory can automatically create CN22 documents on your behalf for eligible shipments. To enable, this functionality, please follow this guide here: http://support.shiptheory.com/support/solutions/articles/24000044841
