HM Revenue & Customs: Customs Duty, Excise Duty and Import VAT: introduction
Quote:
For goods brought in or sent to the UK from the EU there's no extra VAT to pay unless you're ordering or sending purchased goods from one of the EU Special Territories, such as Jersey or Guernsey, in which case you'll have to pay import VAT.
The EU 'Special Territories' are The Aland Islands (Finland), The Canary Islands (Spain), The Channel Islands (UK), The French Overseas Departments of Guadeloupe, French Guiana, Martinique and Reunion and Mount Athos also known as Agion Poros (Greece).
Goods imported to the UK from outside the EU are subject to import VAT, unless they are brought in as part of your duty free allowances.
