Analysis
Heading 5108 of the Harmonized Tariff Schedule covers yarn of fine animal hair (carded or combed), not put up for retail sale. It divides into 2 six-digit subheadings and 6 eight-digit tariff lines, with 6 ten-digit statistical suffixes below them.
None of its 6 lines is duty-free at the general rate. Rates run from 4% to 4% with a median of 4%, so the line you choose sets the duty.
The largest subheadings are 5108.10 (carded, 3 lines) and 5108.20 (combed, 3 lines).
By Census's concordance, most of its statistical lines are made by Fiber, Yarn, and Thread Mills (313110). Those are the NAICS industries a US producer of these goods would report under.
Its median rate of 4% sits at the 43rd percentile of the headings in chapter 51.
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.
