Import Duty Tax Calculator UK - Duty, VAT, and Clearance Fees
Answer: UK import duty tax is estimated by applying the confirmed UK duty rate to customs value, then applying import VAT, commonly 20%, to the VAT base that includes duty and relevant import charges.
- Use the UK Trade Tariff service or UK Global Tariff guidance to confirm the commodity code, duty rate, origin treatment, suspensions, quotas, and trade remedies.
- Import VAT is normally based on customs value plus duty, excise or other import charges, and relevant UK incidental costs when they must be included.
- This is a planning estimate for Great Britain imports. Northern Ireland, excise goods, reliefs, returned goods, low-value ecommerce, and special customs procedures may need different treatment.
- This UK calculator does not use U.S. MPF, HMF, or CBP entry-fee logic.

How the calculation works
This import duty tax calculator UK page delegates to the same calculation as the Import Duty and Tax Calculator UK and UK Customs Duty Calculator. Enter values in GBP after converting supplier invoices, freight, insurance, and clearance costs using the exchange-rate basis required for your planning model or declaration.
| Step | Formula |
|---|---|
| Customs value | goods value + international freight + insurance + other dutiable additions |
| Customs Duty | customs value x UK duty rate |
| Import VAT base | customs value + Customs Duty + excise/additional charges + relevant UK incidental costs |
| Import VAT | import VAT base x import VAT rate |
| Estimated total import charges | Customs Duty + excise/additional charges + import VAT + deferment fee + broker fee |
Use the landed cost calculator when you also need product margin, destination delivery, or per-unit cost. Use the DDP shipping cost calculator when a seller or forwarder quotes duty-paid delivery.
FAQ
How do I calculate UK import duty tax?
Build the customs value, multiply it by the duty rate confirmed for the commodity code and origin, then calculate import VAT on the VAT base that includes customs value, duty, excise or other import charges, and relevant incidental costs.
What UK VAT rate should I enter?
The standard UK VAT rate is commonly 20% for many goods, but reduced, zero-rated, exempt, and special rules can apply. Keep the rate editable until the product treatment is confirmed.
Is import duty tax calculated only on the invoice value?
No. UK customs value and import VAT value can include freight, insurance, duty, excise, and relevant incidental expenses, depending on the charge and declaration treatment.
Does this page calculate the commodity code?
No. It estimates charges after you enter the duty rate. Use the UK Trade Tariff service, HMRC guidance, or a customs broker to confirm commodity code, origin treatment, and rate.
Does this include excise or anti-dumping duty?
Yes, as an editable additional-charge field. Enter excise, anti-dumping, safeguard, levy, or other import charges when they apply to your goods.
Does this include broker and deferment fees?
Yes. Broker and deferment fees are added after HMRC duty, import VAT, and additional import charges so you can compare statutory charges with operational clearance costs.
Is this for Northern Ireland?
It is built for Great Britain planning. Northern Ireland routing can involve different rules depending on product, origin, and whether goods are at risk of moving to the EU.
Can I use this for imports from China or the United States?
Yes for UK import-charge planning if the shipment is entering Great Britain and you enter the correct UK duty rate, origin treatment, customs value, import VAT rate, and fees. For US-origin wording, use the US import tax to UK calculator.

As of May 13, 2026, the UK Trade Tariff service remains the public lookup route for commodity codes, duty rates, VAT treatment, suspensions, quotas, and reductions, and actual duty depends on commodity code, origin, and tariff treatment (GOV.UK Trade Tariff).
