5515.99.05.20 - Combed (410)

This HTS category, 5515.99.05.20, specifically classifies other woven fabrics of synthetic staple fibers that are characterized by being combed. These fabrics are further defined by their composition, containing 36 percent or more by weight of wool or fine animal hair. The "combed" attribute refers to a mechanical process applied to the staple fibers before spinning, which aligns the fibers and removes shorter lengths, resulting in a smoother, stronger, and more uniform yarn that is then used to weave the fabric.

The key differentiator for this subcategory lies in the presence of the combing process. Its sibling, HTS 5515.99.05.10, covers similar fabrics but specifically those that are *not* combed. Therefore, the presence or absence of the combing treatment on the synthetic staple fibers is the primary factor for distinguishing between these two sibling classifications within the "Mixed mainly or solely with wool or fine animal hair" and "Containing 36 percent or more by weight of wool or fine animal hair" context.

As this is a leaf node, there are no further subdivisions under this specific HTS code. Classification is final at this level, determined by the material composition (predominantly synthetic staple fibers mixed with 36% or more wool/fine animal hair) and the finishing process applied to the fibers (combed). Importers and exporters should carefully verify the weight percentages of wool or fine animal hair and confirm whether the synthetic staple fibers used in the fabric's construction have undergone the combing process to ensure accurate classification.
