Last updated: April 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.
AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
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.
