5408.31.05.10 - Not combed (410)

This HTS classification covers woven fabrics of artificial filament yarn that are specifically characterized by being *not combed*. These fabrics fall under the broader category of "Man-made filaments" and are further refined to include woven constructions derived from materials of heading 5405. The key defining features are the use of artificial filament yarn, its woven structure, and the absence of a combing process, alongside a specific fiber composition.

This category is distinguished from its sibling, 5408.31.05.20, by the absence of a combing treatment. While both classifications pertain to woven fabrics of artificial filament yarn mixed mainly or solely with wool or fine animal hair, and containing 36 percent or more by weight of wool or fine animal hair, the distinction lies solely in whether the wool or fine animal hair component has undergone the combing process. Combing is a mechanical process that aligns wool fibers and removes shorter, less desirable fibers, resulting in a smoother, finer yarn and fabric. This classification, therefore, applies to fabrics where this specific finishing step for the animal hair component has not been performed.

As this is a leaf node within the HTS database, there are no further subcategories to introduce. Classification at this level is definitive based on the material composition (containing 36% or more wool/fine animal hair and artificial filament yarn), weave structure, and the processing of the animal hair component (not combed). Examples of goods that would fall here include certain types of suitings, dress fabrics, or upholstery materials where the artificial filament yarn forms the warp or weft and the weft or warp, respectively, is predominantly uncombed wool or fine animal hair.
