Importers of Combed Wool Yarn, Not for Retail Sale, Less Than 85% Wool by Weight paid $42K in duties in April 2026 — an effective duty rate of 18% on $240K in dutiable value, based on actual customs collections rather than the published tariff schedule.
Last updated: April 2026 dataBlended worsted-system yarn with wool content below 85% by weight — frequently combined with polyester, nylon, or fine animal hair for performance or cost reasons — is subdivided in the US schedule by fiber diameter: line 5107203000 covers blends where the wool fiber is 18.5 microns or finer, while 5107206000 captures all other qualifying blended combed yarn. India leads US imports under this heading, with Canada and Italy also significant sources. The dual classification criteria — both wool-content percentage and fiber micron count — mean importers need complete fiber composition and diameter data before filing entry.

Classification depends on which fiber predominates by weight. If wool is the primary fiber but the total wool-plus-fine-hair content is below 85%, heading 510720 may still apply. However, if fine animal hair is the chief weight component, the product may shift to the fine-animal-hair yarn headings in 5108. A detailed fiber-by-fiber weight breakdown from the mill is essential to resolve this.
The US schedule distinguishes blended combed wool yarn made from superfine fibers (≤18.5 microns, line 5107203000) from coarser blended yarn (5107206000). Importers sourcing premium merino-blend yarns should confirm fiber diameter with the spinner, as the applicable 10-digit line — and potentially the duty rate — differs between the two subdivisions.
