Last updated: August 2026 dataWeft-knit and warp-knit fabrics classified under NAICS 313240 are primary inputs for performance apparel, hosiery, swimwear, and medical textile applications where stretch, breathability, and recovery are functional requirements. Warp-knit constructions such as raschel and tricot are widely used in lingerie and sportswear, while circular-knit jersey and interlock fabrics dominate casual and activewear supply chains. HTS classification under Chapter 60 turns on knit type, fiber chief weight, and whether the fabric contains elastomeric yarn — variables that importers must document precisely to avoid reclassification at the port.

Yes. Knit fabrics containing elastomeric yarn (spandex/elastane) may be classified under specific HTS subheadings for fabrics containing rubber or elastomeric filaments, separate from non-elastic knit fabrics of the same fiber type. The percentage of elastomeric yarn by weight and the chief fiber content both factor into the correct subheading determination, so fiber blend certificates from the mill are essential.
Knit fabric lead times are sensitive to yarn availability (particularly for specialty fibers like modal, bamboo, or recycled polyester), dyehouse capacity in the country of manufacture, and minimum order quantities that vary significantly by mill. Seasonal demand spikes for activewear and swimwear fabrics can compress booking windows, making forward purchasing agreements or safety stock strategies important for brands with tight production calendars.
