Analysis
Heading 7605 of the Harmonized Tariff Schedule covers aluminum wire. It divides into 4 six-digit subheadings and 4 eight-digit tariff lines, with 4 ten-digit statistical suffixes below them.
None of its 4 lines is duty-free at the general rate. Rates run from 2.6% to 4.2% with a median of 3.4000000000000004%, so the line you choose sets the duty.
The largest subheadings are 7605.11 (unnamed, 1 line), 7605.19 (unnamed, 1 line), 7605.21 (unnamed, 1 line) and 7605.29 (unnamed, 1 line).
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.
Its median rate of 3.4000000000000004% sits at the 52nd percentile of the headings in chapter 76.
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.
