Last updated: September 2026 dataAcrylic and modacrylic content falls below the 85% threshold in these industrial-grade yarns, meaning the blend's character is partly defined by the secondary fiber mix — a classification distinction that separates them from the higher-concentration acrylic yarn headings. Sold in bulk form not put up for retail, these yarns feed weaving and knitting mills producing apparel, home textiles, and technical fabrics. South Korea and Taiwan are the leading US suppliers, with China and India also significant sources. The four 10-digit lines under this heading (5509690000, 5509692000, 5509694000, 5509696000) reflect further distinctions by fiber combination and construction that affect duty treatment.

When acrylic or modacrylic fibers constitute 85% or more by weight, the yarn classifies under a different HS heading. Below that threshold, the yarn falls under 550969, and the secondary fiber type (e.g., cotton, wool, or other synthetics) may further determine the correct 10-digit HTS line, making fiber composition documentation critical at entry.
Importers should obtain mill certificates or fiber composition test reports specifying the percentage by weight of each fiber component. The four 10-digit lines under this heading distinguish by secondary fiber type and yarn construction, so a certified blend analysis from the manufacturer is the most reliable basis for selecting the correct tariff line and avoiding reclassification at the port.
