U.S. exports of Woven Fabrics of Synthetic Staple Fibers, Under 85%, Mixed Mainly with Other Fibers (N.E.S.) (SITC 65343) totaled $4.8M in August 2026.
Importers of Woven Fabrics of Synthetic Staple Fibers, Under 85%, Mixed Mainly with Other Fibers (N.E.S.) paid $600K in duties in August 2026, an average duty rate of 15.43% — duty actually collected as a share of the imports that cleared customs, not the published tariff schedule. Woven Fabrics of Synthetic Staple Fibers, Under 85%, Mixed Mainly with Other Fibers (N.E.S.) imports of $3.9M in August 2026 ran 43% above the year-to-date monthly average of $2.7M.
Last updated: August 2026 dataResidual in scope, this heading captures woven fabrics where synthetic staple fibers are below 85% by weight and the dominant secondary fiber is neither cotton, wool, fine animal hair, nor manmade filaments — examples include blends with linen, ramie, or other natural fibers not separately enumerated. Because classification here is by exclusion, importers must systematically rule out each more-specific heading before applying this code, making thorough fiber-content analysis and documentation a prerequisite. Blends incorporating novel or specialty natural fibers increasingly appear in sustainable-textile product lines, and correct classification of these emerging constructions is an active area of customs inquiry.

Blends where linen (flax), ramie, jute, or other natural fibers not covered by the cotton or wool headings constitute the largest secondary component would fall here. As sustainable textile sourcing grows, blends incorporating hemp or bamboo-derived staple fibers are also increasingly classified in this residual category.
A laboratory fiber analysis report identifying each component fiber by type and weight percentage, combined with a supplier's material specification sheet, provides the strongest evidentiary basis. Because this heading is reached by exclusion, the documentation should affirmatively show that the secondary fiber is not cotton, wool, fine animal hair, or a manmade filament.
