Last updated: August 2026 dataRaw nylon and polyamide staple fibers in their unprocessed state — not yet carded, combed, or otherwise prepared for spinning — serve as a foundational input for nonwoven fabrics, technical textiles, and carpet manufacturing. The critical classification distinction here is the absence of any spinning preparation: once these fibers are carded or combed, they shift to a different SITC heading. Importers should note that polyamide fiber trade can intersect with Section 301 measures depending on country of origin, making origin documentation a key compliance step.

Any carding, combing, or other mechanical preparation intended to align fibers for spinning moves the product into the processed staple fiber category. Importers should ensure that fiber bales have not undergone these steps prior to entry if they intend to classify under this heading.
Nonwoven fabric producers, carpet and rug manufacturers, and technical textile converters are the dominant buyers. These sectors value the unprocessed form because they apply their own opening and blending processes tailored to specific product specifications.
