Import Duty and Tax Calculator UK - Customs Duty and Import VAT
Answer: UK import duty and tax are estimated by applying the confirmed 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
Use this import duty and tax calculator UK page as an exact-match planning variant of the UK customs duty calculator. Enter all values in GBP after converting foreign currency at the exchange rate required for your declaration or planning model.
| Step | Formula |
|---|---|
| Planning customs value | goods value + international freight + insurance + other dutiable additions |
| Customs Duty | planning customs value x UK duty rate |
| Import VAT base | customs value + Customs Duty + excise/additional import charges + relevant UK incidental costs |
| Import VAT | import VAT base x import VAT rate |
| Estimated import duty and tax | Customs Duty + excise/additional charges + import VAT + deferment fee + broker fee |
The duty rate must come from the UK Trade Tariff or UK Global Tariff treatment for the correct commodity code, origin, and preference status. For wider margin planning, compare the result with the landed cost calculator and DDP shipping cost calculator.
FAQ
How do I calculate import duty and tax in the UK?
Start with customs value, multiply it by the duty rate confirmed from the UK Trade Tariff 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 is the standard UK import VAT rate?
The standard UK VAT rate is commonly 20% for many goods. Reduced, zero-rated, exempt, or special valuation treatment can apply, so the calculator keeps the VAT rate editable.
Is import VAT calculated only on the goods value?
No. UK import VAT is normally based on customs value plus Customs Duty, excise duty or other import charges, and relevant incidental costs such as handling, storage, declaration, or UK destination transport when those costs must be included.
What duty rate should I enter?
Use the rate confirmed from the UK Trade Tariff for the commodity code, origin, and tariff treatment. Free trade agreements, preferences, suspensions, quotas, reliefs, and trade remedies can change the rate.
Does this include excise duty or anti-dumping duty?
Yes, as an editable planning input. Use the excise/additional charges field for alcohol, tobacco, fuel, product levies, anti-dumping duty, safeguard duty, or other charges if they apply.
Is this page for Great Britain or Northern Ireland?
It is built for Great Britain planning. Northern Ireland imports can involve different rules depending on route, origin, and whether goods are at risk of moving to the EU, so confirm NI cases with HMRC or a customs broker.
Does the UK use U.S. MPF or HMF?
No. U.S. Merchandise Processing Fee and Harbor Maintenance Fee are not UK import charges. This UK calculator uses Customs Duty, import VAT, excise or additional charges, deferment fees, and broker fees.
Can this replace HMRC or a customs broker?
No. It is a planning calculator. HMRC systems, the UK Trade Tariff, and your customs broker determine the final commodity classification, valuation, origin treatment, reliefs, import VAT base, and declaration amount.
Is this different from the UK customs duty calculator?
The math is the same, but this page is written for the exact search phrase “import duty and tax calculator UK.” Use the UK customs duty calculator when you want the canonical duty-first page.

| Option | Best for | What it handles | Main limitation |
|---|---|---|---|
| Import duty and tax calculator UK | Searchers estimating UK duty, import VAT, and fees together | Customs Duty, import VAT, excise/additional charges, deferment fee, and broker fee | User must supply the correct commodity-code duty and VAT treatment |
| UK customs duty calculator | Duty-first planning for Great Britain imports | Same calculation with customs-duty framing | Still depends on classification, valuation, origin, and reliefs |
| UK Trade Tariff service | Confirming commodity code, duty rate, VAT rate, suspensions, and trade remedies | Official rate lookup route | Requires correct product classification and origin data |
| Customs broker quote | Final pre-entry clearance estimate | Route, valuation, origin, excise, deferment, and document details | Depends on complete shipment documents and broker assumptions |
| Generic landed cost calculator | Margin comparison across markets | Product cost, freight, duty, tax, and selling costs | Less specific to HMRC import VAT rules |

As of May 13, 2026, the UK Trade Tariff service remains the public lookup route for commodity codes, duty rates, VAT treatment, suspensions, and reductions, and actual duty depends on commodity code, origin, and tariff treatment (GOV.UK Trade Tariff).
As of May 13, 2026, HMRC import VAT guidance says the VAT value starts from customs value and adds Customs Duty or levies, excise duty or other import charges, and relevant incidental expenses where required.
