The CN23 form is a customs declaration form that's now needed when returning items to us with via your local post office (please note: orders being returned from the Republic of Ireland don't need this form as they bypass UK customs). 

It's a new requirement since Brexit, and there shouldn't be any issues as long as you follow our simple guide to filling it in.

 All information required can be found on your return label or the invoice for your order. 

The importer’s name is Internetstores GmbH and you will need to sign both the Declaration of origin and the section To be completed by the sender.
