Analysis
HTS 5101.11.50 covers other: other wool, finer than 44s under heading 5101 (wool, not carded or combed).
There is no general-rate duty on this line, which puts it with roughly 35% of the 82 tariff lines in chapter 51 that are also free. Duty-free at the general rate does not rule out additional duties under Chapter 99, such as Section 301 or Section 232 measures, which depend on the country of origin.
The other lines in the same group are 5101.11.10 (wool for special uses, duty-free), 5101.11.20 (unimproved wool; other wool, not finer than 40s, duty-free), 5101.11.40 (other: other wool, finer than 40s but not finer than 44s, duty-free) and 5101.11.60 (shorn wool: other, 18.7¢/clean kg).
Census statistics map these goods to NAICS 112410 (Sheep Farming), the industry a domestic producer of these goods reports under.
All 4 neighbouring lines carry the same duty-free rate, so a borderline choice between them changes the statistics reported, not the duty paid.
Every edition we compared, from Jan 2023 to Oct 2026 (Rev. 22), shows the same general rate of Free.
