Analysis
Heading 7407 of the Harmonized Tariff Schedule covers copper bars, rods and profiles. It divides into 3 six-digit subheadings and 13 eight-digit tariff lines, with 15 ten-digit statistical suffixes below them.
None of its 13 lines is duty-free at the general rate. Rates run from 1% to 3% with a median of 2.2%, so the line you choose sets the duty.
The largest subheadings are 7407.21 (of copper-zinc base alloys (brass), 5 lines), 7407.29 (other, 5 lines) and 7407.10 (of refined copper, 3 lines).
By Census's concordance, most of its statistical lines are made by Copper Rolling, Drawing, Extruding, and Alloying (331420). Those are the NAICS industries a US producer of these goods would report under.
Its median rate of 2.2% sits at the 45th percentile of the headings in chapter 74.
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.
