Commodity code
A commodity code is the full country-specific tariff number used to declare goods at import — in the UK it is 10 digits and determines the duty rate that applies.

A commodity code is the complete classification number a country uses on customs declarations. It starts with the international six-digit HS code and adds further national digits. In the UK, the import commodity code is 10 digits: the first six are the HS code, the next two the EU-inherited combined-nomenclature subheading, and the last two a UK-specific extension.
The commodity code is what you actually enter on a UK import declaration. It determines the duty rate, whether import VAT is standard, reduced or zero-rated, and whether measures such as licences, quotas, preferential tariffs or anti-dumping duties apply to your goods.
Because the last digits carry real financial consequences, two products that share the same six-digit HS code can still attract different UK duty once the full 10-digit commodity code is resolved.
How it affects your landed cost
The commodity code is the precise lever for the duty line in your landed cost — it is more specific than the six-digit HS code and can shift the rate that applies. Confirming the full UK commodity code before you order means the duty in your landed-cost estimate matches what customs will actually charge, which is what our calculator is built to reflect.
