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.

Published US duty rates

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.

Schedule footnotes

  • See 9903.88.03.

A reference to Chapter 99 means an additional action — a Section 232 or 301 measure, an exclusion, or a quota — applies on top of the rate above.

This is the listed rate. Antidumping and countervailing duty orders, Chapter 99 actions and preference qualification all change what is actually collected, and classification is a judgement about your goods. Verify with your licensed customs broker before you file.
