Classifying goods in chapter 84

Start with the chapter and section notes: they are legally binding and often decide what is included or excluded. Then choose the heading whose wording best describes your product (GRI 1), and work down to the six-digit subheading before choosing the national commodity code.

The six-digit code is shared internationally. The UK and EU add digits for their own tariffs and statistics, and the US uses its own 10-digit HTS lines, so always confirm the final code in the tariff of the country you are importing into.
