Importers of Woven Fabrics of Synthetic Staple Fibers (N.E.S.), Under 85%, Mixed Mainly with Cotton, Over 170 g/m² paid $60K in duties in April 2026 — an effective duty rate of 21% on $288K in dutiable value, based on actual customs collections rather than the published tariff schedule.

Last updated: April 2026 dataCovering synthetic staple fiber blends not elsewhere specified — such as acrylic, modacrylic, or polypropylene staple — mixed mainly with cotton and weighing over 170 g/m², this category captures heavier blended woven constructions that fall outside the dedicated polyester heading. The 'not elsewhere specified' designation means classification here is residual: importers must first confirm the fabric does not qualify under a more specific synthetic-fiber heading before applying this code. Fiber identification testing is particularly important for these residual blends, as misidentification of the dominant synthetic fiber is a common audit finding.
AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
Fibers such as acrylic, modacrylic, polypropylene, and other synthetic staple types that are not polyester are captured here when they are the dominant synthetic component but below 85% by weight. Polyester-dominant blends have their own dedicated heading, so confirming fiber identity through laboratory analysis is the first step in correct classification.
Yes — 'mixed mainly with cotton' means cotton must be the largest single secondary fiber component by weight after the synthetic staple fiber. If another fiber (such as wool or a manmade filament) exceeds the cotton content, the fabric would shift to a different heading covering that predominant secondary fiber.
