China to UK Import Duty Calculator

Estimate UK import duty, import VAT and landed cost for goods bought from China.

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.

How to estimate the landed cost

For a first-pass estimate, add the goods value, freight and insurance to create a simplified customs value. Customs duty is then calculated using the applicable tariff rate. Import VAT is usually calculated on a wider value that includes the customs value and duty, plus certain incidental costs.

Commodity classification comes first

The tariff rate depends on the 10-digit commodity code used for the goods. Search by description above, then compare the returned wording with the actual material, function and construction of the product. A similar-sounding code can lead to a different duty rate or control.

Origin is not the same as dispatch country

Preferential tariff treatment depends on the customs origin of the goods and the relevant agreement or preference scheme, not simply the country the parcel was sent from. BorderMath sends the selected origin to the tariff endpoint to filter measures, but you should still check any origin rules and evidence requirements before claiming preference.

What to verify before declaring

  • the commodity code is correct and declarable;
  • the origin meets any preference rule you plan to claim;
  • any quota, anti-dumping, safeguard, excise or additional-code measure;
  • licences, certificates or documentary conditions;
  • the customs value and import VAT value used on the declaration.
