Subheading

The specific good, identical worldwide

The first six digits are the same in every country that uses the Harmonized System. The United States adds two more for the tariff rate and, often, two more for statistics — which is why the rates below are listed against 8- and 10-digit numbers rather than against this code.

Duty is set at the 8- or 10-digit line, not at this 6-digit subheading, so more than one rate can sit under this code.
