Analysis
Heading 7406 of the Harmonized Tariff Schedule covers copper powders and flakes. It divides into 2 six-digit subheadings and 2 eight-digit tariff lines, with 2 ten-digit statistical suffixes below them.
Every one of its 2 tariff lines is duty-free at the general rate, so classification within the heading affects statistics and Chapter 99 measures rather than the base duty.
Its median rate of duty-free sits at the 6th percentile of the headings in chapter 74.
The largest subheadings are 7406.10 (unnamed, 1 line) and 7406.20 (unnamed, 1 line).
By Census's concordance, most of its statistical lines are made by Nonferrous Metal (except Aluminum) Smelting and Refining (331410). Those are the NAICS industries a US producer of these goods would report under.
The heading text decides whether a product belongs here at all (General Rule of Interpretation 1); the subheadings and lines below it only apply once that is settled. Section and chapter notes can override the heading wording, so read them for borderline goods.
