5515.13.10.20 - Combed (624)

This HTS category, 5515.13.10.20, specifically classifies woven fabrics composed of synthetic staple fibers that are primarily or solely made of polyester staple fibers and have undergone a combing process. The "Combed" designation signifies that the polyester staple fibers have been mechanically treated to align the fibers, removing short fibers and impurities, resulting in a smoother yarn and a higher quality fabric with improved strength and drape. These fabrics are intended for a variety of textile applications where these enhanced characteristics are desired.

This classification is distinguished from its sibling category, 5515.13.10.10, by the presence of the combing process. The "Not combed" category would encompass woven fabrics of polyester staple fibers mixed mainly or solely with wool or fine animal hair where the staple fibers have not undergone this alignment and refinement process. The distinction lies in the physical preparation of the staple fibers before spinning, directly impacting the fabric's finish and performance.

As this is a leaf node, there are no further subcategories within this specific HTS code. Therefore, the focus remains on the precise definition of combed polyester staple fiber woven fabrics mixed mainly or solely with wool or fine animal hair. Classification within this code hinges on confirming the presence of the combing process, the predominant use of polyester staple fibers, and the mixture with wool or fine animal hair.
