Staple fiber fabrics are made from short, cut lengths of polyester that are spun into yarn, producing a softer, more matte surface similar to cotton or wool. Filament fabrics use continuous polyester strands, yielding a smoother, often more lustrous finish. The two fabric types serve overlapping but distinct markets — staple fabrics dominate in apparel and bedding applications where a natural-fiber feel is desired, while filament fabrics are preferred for linings, activewear, and applications requiring sheen or moisture management.

Importers should check for active antidumping duty orders and Section 301 tariff applicability based on the country of origin. Polyester woven fabrics from several major Asian producing countries have been subject to trade remedy proceedings. A licensed customs broker or trade attorney can confirm whether a specific origin and HTS subheading combination carries additional duties at the time of entry.
