How to read chapter 68
Chapter 68 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 14 tariff lines below them are where countries diverge: national suffixes, rate levels and quota notes are set locally.
9 of the 14 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.
