The US tariff schedule, by chapter

Every line of the Harmonized Tariff Schedule of the United States: 0 codes across 0 chapters, with the duty rate on each. Re-checked daily against USITC, because the schedule is revised fifteen to eighteen times a year.

"Covers" shows the chapter's first heading, as published. Chapters 98 and 99 are US special provisions rather than ordinary goods: Chapter 99 is where Section 301, Section 232 and other additional duties live.
