5515.13.10.10 - Not combed (624)

This HTS category, 5515.13.10.10, specifically covers woven fabrics manufactured from synthetic staple fibers, where these fibers are *not combed*. These fabrics are further characterized by being composed primarily or solely of polyester staple fibers and being mixed with wool or fine animal hair. The "not combed" designation refers to the physical state of the synthetic staple fibers before they are spun into yarn and subsequently woven. This implies a less refined fiber preparation process compared to combed fibers.

This classification is distinguished from its sibling category, 5515.13.10.20, by the crucial distinction of the fiber preparation. While both categories deal with woven fabrics of polyester staple fibers mixed with wool or fine animal hair, 5515.13.10.20 applies to fabrics where the synthetic staple fibers have undergone a combing process. Combing is a textile process that aligns fibers, removes short fibers, and results in a smoother, stronger yarn and a finer fabric. Therefore, the key differentiator lies in the degree of processing applied to the synthetic staple fibers.

As this is a leaf node in the HTS classification, there are no further subcategories. The classification is precise at this level, focusing on the combination of synthetic staple fiber origin (polyester), the type of fibers used (staple), the weaving process, the presence of wool or fine animal hair in a mixture, and the specific preparation of the synthetic staple fibers (not combed). Examples of products falling under this classification could include certain types of suiting, outerwear fabrics, or upholstery materials where the uncombed nature of the polyester staple fibers is a defining characteristic.
