Common questions

What does HTS Chapter 38 cover?

Chapter 38 of the US Harmonized Tariff Schedule covers miscellaneous chemical products. It contains 27 four-digit headings and 214 tariff lines.

What is the duty rate for Chapter 38 goods?

General duty rates from 0.1% to 6.5%, with 54 duty-free lines; 3 lines carry a specific or compound duty. The rate that applies depends on the specific tariff line and the country of origin — preferential trade agreements can reduce or eliminate the general rate.

How do I find the right HTS code in Chapter 38?

Classification depends on the material, construction, and intended use of the product. Browse the headings on this page, or describe your product in the search box to get a candidate code with its duty rate.
