How UK import charges work

The duty shown is the standard rate for goods from countries without a trade deal. Goods from a country with a UK trade agreement may pay less, or nothing, if they meet the rules of origin. A few products from certain countries also pay anti-dumping duties. The UK charges import VAT on the customs value plus shipping, insurance and duty.
