How to read chapter 29
Chapter 29 is part of the international Harmonized System, not a US invention — the chapter and heading boundaries are shared with every country that uses HS 2022. The 89 tariff lines below them are where countries diverge: national suffixes, rate levels and quota notes are set locally.
20 of the 89 lines in this chapter carry a general rate of Free. That is a statement about the general column only — Section 301, AD/CVD and quota measures are applied on top and are not reflected here.
