Analysis
HTS 5101.30.40 covers not processed in any manner beyond the carbonized condition: other under heading 5101 (wool, not carded or combed).
The general rate is 24.4¢/kg, a specific or compound duty rather than a simple percentage, so the effective burden depends on the unit value of the goods: cheap goods pay proportionally more than expensive ones. Importers usually convert it to an ad valorem equivalent to compare it with other lines.
Goods that qualify under the Australia FTA, the Bahrain FTA, the Chile FTA, the Colombia TPA, the Caribbean Basin Initiative, and 10 others can enter duty-free instead of paying 24.4¢/kg. It is also eligible under GSP, the developing-country programme, which Congress has to renew; check whether GSP is in force on the entry date.
Census statistics map these goods to NAICS 313110 (Fiber, Yarn, and Thread Mills), an industry of 250 US establishments employing 18,290 people. That is the industry code a US manufacturer of the same product would normally use.
Every edition we compared, from Jan 2023 to Oct 2026 (Rev. 22), shows the same general rate of 24.4¢/kg.
