Explore global trade with HS codes

HS Code 5503 covers synthetic staple fibers, not carded, combed or otherwise processed for spinning. The classification is organized by fiber type, with detailed subcategories for nylon/polyamide fibers (5503.11-5503.19), polyester fibers (5503.20), acrylic/modacrylic fibers (5503.30), polypropylene fibers (5503.40), and other synthetic fibers (5503.90). This category provides the raw material inputs for spun yarn production in the synthetic textile sector. Products typically take the form of fiber bundles or tow with specific fiber length, denier (thickness), and crimp characteristics. Technical specifications focus on tenacity, elongation, and dyeability parameters. Unlike continuous filament (HS 5402), these cut fibers are designed for processing on traditional spinning systems originally developed for natural fibers, enabling blending with cotton, wool, or other natural fibers.
