5112.20 - Other, mixed mainly or solely with man-made filaments:

This HTS category, 5112.20, encompasses woven fabrics composed primarily of wool or fine animal hair that have been specifically mixed with man-made filaments. The key distinguishing feature here is the presence of these man-made filaments, which differentiate these fabrics from those woven solely from wool or fine animal hair, or those mixed with man-made staple fibers. The "mainly or solely" wording indicates that the filament component, while present, does not constitute the majority of the fabric by weight.

Compared to its sibling categories, 5112.20 is distinct from categories containing 85 percent or more wool or fine animal hair, as those fabrics may contain other fibers but are predominantly animal hair. It also differs from 5112.30, which specifies mixtures with man-made *staple fibers* rather than filaments. Furthermore, the catch-all category 5112.90 covers woven fabrics of combed wool or fine animal hair not otherwise specified.

The subcategories within 5112.20 further refine the classification based on the specific end-use and weight of the fabric. 5112.20.10.00 and 5112.20.20.00 distinguish between tapestry and upholstery fabrics based on their weight per square meter, indicating different applications and construction densities. The residual category, 5112.20.30.00, covers all other woven fabrics meeting the general description of this heading but not falling into the specific tapestry or upholstery subcategories.
