Every HTS Code Covered (215)

The codes the in-force headings list, from the U.S. notes to Chapter 99. A code covers every line under it, and a heading that takes precedence (an exemption, a deal rate) can switch it off for some goods. Whether a product is in scope also depends on the note's written description, which the importer or their customs broker decides.

Yes. On October 26, 2026, 4 of their Chapter 99 headings are in force.

Which HTS codes are subject to the Section 232 truck and bus tariffs?

215 HTS codes are listed under the headings in force on October 26, 2026. This page lists every one, with its heading and rate. A listed code covers every line under it, and whether a product is in scope also depends on the written description in the U.S. notes to Chapter 99.

How do I check whether the Section 232 truck and bus tariffs apply to my import?

Find your HTS code in the tables on this page, or enter it with the country of origin in the free HTS Hero tariff calculator, which applies every Chapter 99 heading in force on the entry date. Scope also depends on the written description of the products covered, which the importer or their customs broker decides.
