5515.99.10.20 - Combed (624) 🖩

This HTS category, 5515.99.10.20, specifically classifies other woven fabrics of synthetic staple fibers that are predominantly or solely mixed with wool or fine animal hair, and critically, are **combed**. This means that the synthetic staple fibers, as well as any wool or fine animal hair components, have undergone a combing process. Combing is a mechanical process that aligns fibers, removes shorter staples, and purifies the fiber stock, resulting in a smoother, finer yarn with improved strength and a more lustrous appearance.

This classification is distinguished from its sibling category, 5515.99.10.10, which covers similar woven fabrics but are *not* combed. The presence or absence of the combing process is the definitive factor for differentiating between these two subcategories. Therefore, when classifying a fabric under 5515.99.10, importers must ascertain whether the constituent fibers have been subjected to this preparatory step.

As this is a leaf node in the HTS, there are no further subcategories. The classification is complete at this level, contingent upon the fabric meeting the criteria of being woven, made from synthetic staple fibers, mixed mainly or solely with wool or fine animal hair, and having undergone the combing process. Examples of such fabrics would include high-quality worsted-spun fabrics with a synthetic staple fiber blend, intended for use in apparel or upholstery where a refined finish is desired.
