UK Customs Duty & Import VAT Calculator
Enter your shipment values in GBP (£). This tool estimates duty, VAT, and total landed cost.
How customs duty is usually calculated in the UK
For many standard imports, the process is straightforward:
- Customs value is often the goods value plus shipping and insurance.
- Customs duty is a percentage of the customs value (based on commodity code and origin).
- Import VAT is usually charged on customs value + duty + certain other costs (such as excise, if applicable).
The calculator follows this typical structure so you can get a fast, practical estimate before purchase or shipment.
Step-by-step: using this customs duty calculator UK
1) Enter your base shipment values
Add the goods price, shipping, and insurance in GBP. If your supplier invoice is in another currency, convert first.
2) Choose or enter your duty rate
The precise duty rate comes from your product’s commodity code and trade origin. You can select a common preset or type your own rate manually.
3) Set VAT and optional charges
The standard UK VAT rate is 20% for many goods, but some goods use reduced or zero rates. If excise applies (for example, alcohol or tobacco), add it. You can also include a courier clearance fee for a fuller landed-cost estimate.
4) Click calculate
You’ll get a breakdown of duty, VAT, and total estimated import charges, plus total landed cost.
Typical duty-rate examples (for orientation only)
| Product type | Example duty rate | Notes |
|---|---|---|
| Books/publications | 0% | Often zero-rated for duty; VAT treatment can vary. |
| General goods | ~2.5% | Common reference rate for simple estimates. |
| Electronics/components | 0–4% | Depends heavily on classification. |
| Clothing/textiles | Can be higher (e.g., around 12%) | Frequently higher duty categories. |
What affects your final import bill?
- Commodity code: wrong code = wrong duty and possible correction.
- Country of origin: trade agreements may reduce duty.
- Incoterms: determines which costs are included and who pays what.
- Reliefs/exemptions: some shipments qualify for reduced charges.
- Carrier handling fees: often charged separately from HMRC taxes.
Example calculation
Suppose you import goods worth £300, shipping is £30, insurance is £0, duty rate is 4%, and VAT is 20%:
- Customs value = £330
- Duty = £330 × 4% = £13.20
- VAT base = £330 + £13.20 = £343.20
- Import VAT = £343.20 × 20% = £68.64
- Total import charges (before courier fee) = £81.84
This is exactly the style of breakdown shown by the calculator.
