About HS Code 550951

This category includes yarns, excluding sewing thread, made from polyester staple fibres blended predominantly or entirely with artificial staple fibres, and not prepared for retail sale. These blended yarns are highly valued in the textile industry for combining the desirable properties of both fiber types – polyester for strength, durability, and wrinkle resistance, and artificial fibers (like rayon or modal) for softness, drape, and moisture absorption. They are widely used by fabric manufacturers for apparel, home textiles, and technical applications where a balance of performance and comfort is desired. Importers are typically textile mills seeking specific aesthetic and performance characteristics for their end products, while exporters are specialized yarn spinners. The trade in these yarns reflects the demand for versatile and comfortable fabrics in the global market.
