U.S. imports of woven synthetic filament fabric, nes (≥85% by weight, non-polyester) (SITC 65317) totaled $5.6M in April 2026, traded with 38 countries.
Importers of Woven Synthetic Filament Fabric, NES (≥85% by Weight, Non-Polyester) paid $1.1M in duties in April 2026 — an effective duty rate of 22% on $5.1M in dutiable value, based on actual customs collections rather than the published tariff schedule.
Last updated: April 2026 dataNylon, polypropylene, and other synthetic filament yarns not elsewhere specified fall into this residual category when they constitute at least 85% of a woven fabric's weight — capturing constructions that don't qualify as polyester (SITC 65315/65316) or as staple-fiber fabrics. End uses span outdoor gear, industrial filtration, geotextile precursors, and specialty apparel where non-polyester synthetics offer specific performance properties such as abrasion resistance or chemical inertness. The 'NES' designation means classification here is appropriate only after ruling out more specific synthetic-filament headings. Trade remedy exposure varies by fiber type and country of origin, so a tariff engineering review is advisable when sourcing nylon-dominant fabrics.

Nylon (polyamide) and polypropylene filament fabrics at ≥85% fiber content are the most frequent candidates, since polyester filaments have their own dedicated headings (65315 and 65316). Other synthetics such as polyethylene or specialty high-performance filaments may also fall here when no more specific classification applies.
The broker should first determine whether any single synthetic filament type meets the ≥85% by-weight threshold. If polyester qualifies, the fabric belongs in 65315 or 65316 depending on texturing. If a different synthetic meets the threshold and no more specific heading applies, SITC 65317 is appropriate. When no single fiber dominates at 85%, blended-fabric headings apply instead.
