U.S. imports of Textured Nylon & Polyamide Filament Yarn (Non-Sewing Thread, Bulk) (SITC 65151) totaled $3.0M in August 2026, imported from 28 countries.
Importers of Textured Nylon & Polyamide Filament Yarn (Non-Sewing Thread, Bulk) paid $335K in duties in August 2026, an average duty rate of 11.12% — duty actually collected as a share of the imports that cleared customs, not the published tariff schedule. Textured Nylon & Polyamide Filament Yarn (Non-Sewing Thread, Bulk) imports of $3.0M in August 2026 ran 16% above the year-to-date monthly average of $2.6M.
Last updated: August 2026 dataTexturing — through false-twist, air-jet, or stuffer-box processes — gives nylon and other polyamide filament yarns the bulk, stretch, and moisture-wicking properties demanded by hosiery, activewear, and technical textile manufacturers. Sold in bulk (not packaged for retail), this yarn is an industrial input rather than a consumer product, and its classification under SITC 65151 requires clear documentation that it is not sewing thread. Section 301 tariff exposure applies to shipments originating from China, making supplier diversification a live cost consideration for US knitters and weavers.

Customs authorities generally recognize false-twist, stuffer-box, air-jet, knit-de-knit, and gear-crimping as texturing methods that impart bulk or stretch. The yarn must exhibit these physical characteristics — not merely be labeled as textured — to support the classification. Lab testing or manufacturer process documentation may be requested during a CBP audit.
Bulk industrial packaging (large cones, cheese packages, or beams) must be clearly described on the commercial invoice and packing list. If a shipment contains any retail-packaged units, those units may fall under a different subheading with a different duty rate. Importers should ensure that packaging specifications are consistent across all shipping documents to avoid split-classification issues at entry.
