SITCSection 6
U.S. imports of woven synthetic filament yarn fabric, nes (other blends) (SITC 65319) totaled $2.0M in April 2026, traded with 46 countries.
Importers of Woven Synthetic Filament Yarn Fabric, NES (Other Blends) paid $375K in duties in April 2026 — an effective duty rate of 23% on $1.6M in dutiable value, based on actual customs collections rather than the published tariff schedule. Woven Synthetic Filament Yarn Fabric, NES (Other Blends) imports of $2.0M in April 2026 ran 14% below the year-to-date monthly average of $2.3M.
Last updated: April 2026 dataResidual woven fabrics of synthetic filament yarns — those not captured by the polyester-specific or cotton-blend headings — land in this catch-all classification, which serves as the final sorting point for mixed or specialty synthetic constructions. Fabrics here may combine nylon filaments with wool, viscose, or other non-cotton fibers, or represent novel fiber combinations that don't meet the thresholds of more specific SITC codes. Because this is an NES (not elsewhere specified) category, correct classification requires a systematic process of elimination through the more specific synthetic-filament headings. Trade professionals should document the elimination rationale in their classification records to support any post-entry review.

The classifier should first test whether the fabric meets the ≥85% threshold for textured polyester (65315), non-textured polyester (65316), or other synthetic filaments (65317). If it falls below 85% synthetic content, check whether cotton is the primary secondary fiber (65318). Only after ruling out all those headings — and confirming the fabric is not pile, chenille, or narrow — does SITC 65319 apply.
Yes, a woven fabric of nylon filament mixed mainly with viscose (rather than cotton) and below the 85% synthetic threshold would be a candidate for SITC 65319, provided no more specific heading captures it. The key is that viscose is not cotton, so the cotton-blend heading (65318) would not apply, and the NES residual category becomes the appropriate classification.
