Same mug. Two codes. Eight points of duty.
Is a glazed coffee mug porcelain or stoneware? It sounds like a detail. To customs, it's a different heading and a different duty rate on every shipment.
Switch between the two codes to see what the difference costs on a £100,000 shipment.
- Shipment value
- £100,000
- Duty rate
- 12%
- Duty paid
- £12,000
UK Global Tariff third-country rates. Mugs from China also carry anti-dumping duty of up to 36.1%, depending on the manufacturer.
What one wrong digit actually costs
You overpay duty
A product entered under a higher-rate heading pays more duty on every shipment, often for years, without anyone noticing.
You underpay, and HMRC notices
Too little duty paid can lead to back-dated demands, interest and penalties, and more checks on future shipments.
You miss trade-deal savings
Preferential rates under UK trade agreements depend on the right code. Get the code wrong and the saving is lost.
You miss anti-dumping and CBAM exposure
Trade remedies and carbon border rules are scoped by commodity code. A wrong code hides the exposure until it's expensive.
Your landed cost is wrong
If the duty is wrong, your margins, pricing and sourcing decisions are built on the wrong number.
Your classification is only as good as its proof
Without reasoning on record, even a correct code is hard to defend in an HMRC audit.

New to tariff classification?
What is an HS or commodity code?
It's the number that identifies your product in the customs tariff. It sets the duty rate you pay, the trade deals you can use and the rules that apply at the border. In the UK, imports need a 10-digit commodity code.
Why not just use the free UK Trade Tariff?
The Trade Tariff lists every code, but it leaves the decision to you. TariffTel tells you which code fits your product and explains why. With TTVerified, a specialist verifies it and keeps an audit trail.
