U.S. imports of woven synthetic staple fiber fabric, nes (≥85% by weight, non-polyester/non-acrylic) (SITC 65329) totaled $744K in April 2026, traded with 20 countries.
Importers of Woven Synthetic Staple Fiber Fabric, NES (≥85% by Weight, Non-Polyester/Non-Acrylic) paid $198K in duties in April 2026 — an effective duty rate of 26% on $755K in dutiable value, based on actual customs collections rather than the published tariff schedule. Woven Synthetic Staple Fiber Fabric, NES (≥85% by Weight, Non-Polyester/Non-Acrylic) imports of $744K in April 2026 ran 29% below the year-to-date monthly average of $1.1M.
Last updated: April 2026 dataPolypropylene, polyvinyl alcohol, and other synthetic staple fibers not captured by the polyester (SITC 65321) or acrylic/modacrylic (SITC 65325) headings fall here when they constitute at least 85% of a woven fabric's weight. End uses for these specialty constructions include geotextiles, filtration media, and industrial fabrics where specific chemical resistance or thermal properties of non-standard synthetics are required. The NES designation makes systematic classification elimination essential — importers must confirm the fiber is neither polyester nor acrylic before applying this code. As with other synthetic fabric categories, trade remedy applicability depends on both fiber type and country of origin.

Polypropylene (PP) staple fiber fabrics are the most common candidates, as polypropylene is neither polyester nor acrylic. Polyvinyl alcohol (PVA) and certain specialty engineering-fiber staple fabrics may also fall here. The key qualifier is that the fiber must be synthetic (not natural or regenerated/artificial), present at ≥85% by weight, and not covered by a more specific heading.
Best practice is to maintain a written classification rationale that walks through the elimination of more specific headings — confirming the fiber is not polyester (ruling out 65321) and not acrylic or modacrylic (ruling out 65325) — supported by a laboratory fiber-content report. This documentation is valuable in the event of a CBP inquiry or post-entry audit challenging the NES classification.
