5515.99.10.10 - Not combed (624)

This classification, HTS 5515.99.10.10, pertains to other woven fabrics of synthetic staple fibers that are specifically *not combed*. These fabrics are characterized by their composition of synthetic staple fibers, meaning they are made from short, discontinuous synthetic filaments, and importantly, these fibers have not undergone the combing process. This lack of combing often results in a fabric with a slightly less uniform texture and potentially more fiber irregularities compared to its combed counterpart.

The key differentiator for this category lies in the absence of the combing process for the synthetic staple fibers. It is distinct from its sibling category, 5515.99.10.20, which specifically covers woven fabrics of synthetic staple fibers that *have been combed*. Combing is a process that aligns and removes short fibers, leading to a smoother, more refined yarn and consequently, a fabric with enhanced appearance and feel.

As this is a leaf node within the HTS structure, there are no further subcategories to introduce. Classification within HTS 5515.99.10.10 is final for fabrics meeting the criteria of being woven, composed of synthetic staple fibers, and not combed, within the broader context of "Other woven fabrics of synthetic staple fibers: Other woven fabrics: Other: Mixed mainly or solely with wool or fine animal hair: Other."
