You must complete a Commercial Invoice if you wish to ship outside the EU.
Shipping within the European Union is not classed as international, so there are no taxes to pay and a Commercial Invoice is not necessary.
If you have an unusual item to send we are more than happy to check the specific judgement on that item with the courier you wish to send it with. Email our Customer Service team with your inquiry.
