Analysis
Heading 5101 of the Harmonized Tariff Schedule covers wool, not carded or combed. It divides into 5 six-digit subheadings and 30 eight-digit tariff lines, with 34 ten-digit statistical suffixes below them.
Every one of its 30 tariff lines is duty-free at the general rate, so classification within the heading affects statistics and Chapter 99 measures rather than the base duty.
Its median rate of duty-free sits at the 18th percentile of the headings in chapter 51.
8 of the lines carry specific or compound rates (per kilogram, per dozen and so on) rather than a percentage, so their burden depends on the unit value of the goods.
The largest subheadings are 5101.21 (shorn wool, 7 lines), 5101.29 (other, 7 lines), 5101.30 (carbonized, 6 lines) and 5101.11 (shorn wool, 5 lines).
By Census's concordance, most of its statistical lines are made by Fiber, Yarn, and Thread Mills (313110), Sheep Farming (112410) and Animal (except Poultry) Slaughtering (311611). Those are the NAICS industries a US producer of these goods would report under.
