How UK import duty is calculated
Understanding the formula stops you from underpaying — and risking a penalty — or overpaying and losing margin on every order.
UK import duty is charged on the customs value, not just your supplier invoice. The customs value is the CIF value: supplier cost plus international freight plus insurance. If your supplier quotes FOB, you must add freight and insurance before calculating duty.
Worked example: 500 cotton T-shirts from China
The supplier cost was £4.00 per T-shirt. The border alone adds £1.83 per unit before UK delivery. Landed cost — not supplier price — is the only number that matters for your margins.
What if you sourced from Bangladesh instead?
