5408.31.05.20 - Combed (410)

This HTS category, 5408.31.05.20, specifically classifies woven fabrics of artificial filament yarn that are *combed* and contain 36 percent or more by weight of wool or fine animal hair. The "combed" designation refers to a post-spinning treatment of the artificial filament yarn, where it undergoes a process to remove short fibers and align the longer ones, resulting in a smoother, more uniform yarn. These fabrics are derived from artificial filament yarn, meaning they are made from manufactured fibers like rayon, nylon, or polyester that have been extruded into continuous filaments. The key distinguishing feature within this 8-digit code is the presence of combed artificial filament yarn, which is integrated into a woven fabric structure that is predominantly composed of wool or fine animal hair.

This classification distinguishes itself from its sibling category, 5408.31.05.10, based on the physical processing of the artificial filament yarn used. While both categories cover unbleached or bleached woven fabrics mixed mainly or solely with wool or fine animal hair and containing 36 percent or more by weight of wool or fine animal hair, this node specifically requires the artificial filament yarn to have undergone a combing process. The sibling category, conversely, applies to fabrics where the artificial filament yarn is *not* combed. This difference in yarn treatment can affect the fabric's texture, drape, and overall appearance, making the distinction important for precise classification.

As this is a leaf node in the HTS, there are no further subcategories. The classification is complete at this level, focusing on the specific combination of woven structure, the use of artificial filament yarn (specifically combed), and the significant proportion of wool or fine animal hair. Examples of fabrics falling under this classification might include certain types of fine woolen blends with a smooth, lustrous finish imparted by the combed artificial filament.
