Import VAT estimator

UK import VAT calculator

Estimate the import VAT element separately, then see how it contributes to the full landed cost.

UK landed cost calculator

Build the customs value, apply a tariff rate, estimate import VAT and see the total landed cost. You can search the UK Trade Tariff or enter a known 10-digit commodity code.

1. Find the tariff classification

Start with a product description or enter the code if you already know it.
Classification matters: choose the description that actually matches the goods.
Use the customs origin of the goods, not simply the seller, warehouse or dispatch country.

2. Enter the shipment values

Enter a rate manually or check the official tariff above.
20% UK standard-rate planning default. Official commodity data can automatically replace it with a clear reduced or zero rate when applicable.
Enter the customs/tariff weight when the official rate is charged per kg, 100 kg or tonne. BorderMath will use it automatically.
Affects the £135 low-value customs-duty rule. HMRC may detect excise goods automatically. Excise Duty itself is not included in this estimate.
Simplified planning model for Great Britain: customs value = goods + freight + insurance. Import VAT is estimated on customs value + duty + other import costs unless you mark VAT as already accounted for. Current low-value and VAT rules can change and Northern Ireland rules differ.

Do not use this estimate as a customs declaration. Preference eligibility, rules of origin, quotas, anti-dumping duties, excise, additional codes and certificates can change the amount due.

What value is import VAT based on?

This calculator uses a simplified VAT value of goods + freight + insurance + customs duty + other import costs you enter. Actual import VAT valuation can include other incidental expenses and special rules, so the declaration figure may differ.

Postponed VAT Accounting

VAT-registered businesses may be able to account for import VAT through their VAT return rather than paying it at the border. Eligibility and accounting treatment are outside this calculator; check current HMRC guidance for your circumstances.
