    {
      "q": "How do I calculate customs duty in the UK?",
      "a": "For planning, build the customs value from goods value, international freight, insurance, and dutiable additions, then multiply by the duty rate confirmed from the UK Trade Tariff for the commodity code and origin."
    },
    {
      "q": "How is UK import VAT calculated?",
      "a": "Import VAT is normally calculated on the customs value plus Customs Duty, excise duty or other import charges, and relevant incidental costs such as handling or UK destination transport when they must be included."
    },
    {
      "q": "What VAT rate should I use for UK imports?",
      "a": "The standard UK VAT rate is 20% for many goods, but reduced, zero, exempt, or special valuation treatment can apply. The calculator leaves the import VAT rate editable so you can match the commodity and HMRC treatment."
    },
    {
      "q": "Does this calculator include excise duty?",
      "a": "It includes an editable excise or additional charges field for alcohol, tobacco, fuel, product levies, anti-dumping duty, safeguard duty, or other import charges. It does not classify those charges automatically."
    },
    {
      "q": "Does this replace the UK Global Tariff or HMRC guidance?",
      "a": "No. Use the UK Trade Tariff service to confirm commodity code, origin, duty rate, VAT treatment, suspensions, quotas, reliefs, and trade remedies before making a customs declaration."
    },
    {
      "q": "Is this for Northern Ireland imports?",
      "a": "It is designed for Great Britain planning. Northern Ireland movements can involve different rules depending on whether goods are at risk of moving to the EU, so confirm the route with HMRC or a customs broker."
    },
    {
      "q": "Does the UK charge U.S. MPF or HMF?",
      "a": "No. MPF and HMF are U.S. customs fees. This UK calculator uses duty, import VAT, excise or additional import charges, deferment fees, and broker fees instead."
