Last updated: May 2026 dataCotton is the dominant secondary fiber in these blended yarns, a combination widely used in mid-weight apparel fabrics, workwear, and home textiles where cotton's comfort properties are paired with the strength and wrinkle resistance of synthetic staple fibers. At under 85% synthetic content by weight, classification hinges on the 'mixed mainly with cotton' qualifier, which requires that cotton outweigh any other non-synthetic fiber present. India and Turkey are the primary US suppliers, reflecting both countries' integrated cotton-spinning and synthetic-blending capacity. This heading resolves to a single 10-digit line, 5509920000.
AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
'Mixed mainly with cotton' means cotton constitutes a greater proportion by weight than any other single non-synthetic fiber in the blend. Importers should secure fiber composition certificates from the spinner showing the percentage breakdown of each component; if cotton does not outweigh other non-synthetic fibers, the yarn may fall under a different subheading such as 550999.
Synthetic staple fiber yarns from certain origins can be subject to antidumping or countervailing duty orders, and the textile sector has also seen Section 301 exposure for Chinese-origin goods. Importers should check the USITC and Commerce Department's active order lists against the specific 10-digit HTS line and country of origin before finalizing sourcing decisions.
