Analysis
HTS 1505.00.10 covers wool grease, crude under heading 1505 (wool grease and fatty substances derived therefrom (including lanolin)).
The general rate is 1.3¢/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 GSP, the Australia FTA, the Bahrain FTA, the Chile FTA, the Colombia TPA, and 12 others can enter duty-free instead of paying 1.3¢/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.
The other line in the same group is 1505.00.90 (wool grease and fatty substances derived therefrom…, 2.4%).
Census statistics map these goods to NAICS 313110 (Fiber, Yarn, and Thread Mills), an industry of 250 US establishments employing 18,290 people, the industry a domestic producer of these goods reports under.
Every edition we compared, from Jan 2023 to Oct 2026 (Rev. 22), shows the same general rate of 1.3¢/kg.
