Analysis
Heading 5502 of the Harmonized Tariff Schedule covers artificial filament tow. It divides into 2 six-digit subheadings and 2 eight-digit tariff lines, with 2 ten-digit statistical suffixes below them.
None of its 2 lines is duty-free at the general rate. Rates run from 7.5% to 7.5% with a median of 7.5%, so the line you choose sets the duty.
Its median rate of 7.5% sits at the 23rd percentile of the headings in chapter 55.
The largest subheadings are 5502.10 (unnamed, 1 line) and 5502.90 (unnamed, 1 line).
By Census's concordance, most of its statistical lines are made by Artificial and Synthetic Fibers and Filaments Manufacturing (325220). 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.
