How these numbers were computed

Counts come from the 2026HTSRev19 (Revision 19 (2026), in effect from 09/15/2026) edition of the USITC Harmonized Tariff Schedule, chapters 1-97, read through the USITC API. A tariff line is a code that carries a duty rate; the general column is the normal trade relations (MFN) rate. Section 301 membership is matched from the HTS Chapter 99 U.S. notes 20 and 31 lists. List codes are counted as named in the notes, so they differ from line counts. Per-chapter detail: US tariff rates by chapter.
