HS code 600631 covers: Fabrics; knitted or crocheted fabrics, other than those of headings 60.01 to 60.04, of synthetic fibres, unbleached or bleached. HS 600631 covers unbleached or bleached knitted or crocheted fabrics made from synthetic fibres, excluding those of headings 60.01 to 60.04. These versatile fabrics are foundational for a wide range of applications, from activewear and sportswear to industrial textiles and linings. Major importers include sportswear brands, activewear manufacturers, and producers of technical textiles who value the inherent properties of synthetics like durability, moisture-wicking, and stretch. Exporters are typically large chemical and textile companies in countries with strong petrochemical industries and advanced synthetic fiber production. Key aspects of trade involve the specific type of synthetic fiber (e.g., polyester, nylon, spandex), fabric construction, weight, and technical specifications for various end-uses, often traded as bulk commodities.

Often confused with 5407 (woven fabrics of synthetic filament yarn, unbleached or bleached) or 6005 (warp knit fabrics of synthetic fibres), due to the distinction between knitting/weaving and specific knitting types.
