About HS Code 540245

This HS code pertains to fine, non-textured, non-high tenacity nylon (polyamide) filament yarns, with a linear density under 67 decitex. These yarns are single, have a low twist (50 turns or less per meter), and are exclusively for industrial use, not retail or sewing. Nylon is prized for its strength, elasticity, abrasion resistance, and smooth feel, making these fine yarns suitable for delicate yet durable fabrics. Importers are typically manufacturers of hosiery, lingerie, lightweight apparel, and technical textiles in countries with developed textile industries, including Italy, Germany, and various Asian manufacturing hubs. Exporters are often large-scale synthetic fiber producers, primarily from China, Taiwan, South Korea, and the USA, where the necessary petrochemical infrastructure and spinning technologies are well-established. The "less than 67 decitex" signifies a very fine yarn, ideal for sheer or lightweight applications, while the "not high tenacity or textured" distinguishes it from more specialized nylon yarns.
