Analysis
Heading 7604 of the Harmonized Tariff Schedule covers aluminum bars, rods and profiles. It divides into 3 six-digit subheadings and 7 eight-digit tariff lines, with 13 ten-digit statistical suffixes below them.
None of its 7 lines is duty-free at the general rate. Rates run from 1.5% to 5% with a median of 3%, so the line you choose sets the duty.
The largest subheadings are 7604.10 (of aluminum, not alloyed, 3 lines), 7604.29 (other, 3 lines) and 7604.21 (unnamed, 1 line).
Its median rate of 3% sits at the 37th percentile of the headings in chapter 76.
By Census's concordance, most of its statistical lines are made by Other Aluminum Rolling, Drawing, and Extruding (331318). 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.
