Analysis
Heading 7409 of the Harmonized Tariff Schedule covers copper plates, sheets and strip, of a thickness exceeding 0.15 mm. It divides into 8 six-digit subheadings and 17 eight-digit tariff lines, with 29 ten-digit statistical suffixes below them.
None of its 17 lines is duty-free at the general rate. Rates run from 1% to 3% with a median of 3%, so the line you choose sets the duty.
The largest subheadings are 7409.19 (other, 3 lines), 7409.31 (in coils, 3 lines), 7409.39 (other, 3 lines) and 7409.90 (of other copper alloys, 3 lines).
Its median rate of 3% sits at the 74th percentile of the headings in chapter 74.
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.
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.
