5112.30 - Other, mixed mainly or solely with man-made staple fibers:

HTS code 5112.30 encompasses woven fabrics composed primarily of wool or fine animal hair that have been combed, and which are further mixed, predominantly or exclusively, with man-made staple fibers. This category focuses on the nature of the blending fibers, specifically identifying man-made staple fibers as the secondary component that defines the fabric's classification.

Distinguishing this category from its siblings, 5112.30 differentiates itself by the type of man-made fiber used in the mixture. It is distinct from 5112.20, which covers fabrics mixed mainly or solely with man-made filaments, and also from the "Other" category at 5112.90, which would include blends with other materials not specified as man-made staple fibers or filaments. The key differentiator here is the presence and predominance of man-made staple fibers in conjunction with combed wool or fine animal hair.

The subcategories within 5112.30 further refine the classification based on specific fabric types and weight. 5112.30.10.00 and 5112.30.20.00 specifically address tapestry and upholstery fabrics, differentiating them by weight thresholds (exceeding 300 g/m² and not exceeding 140 g/m², respectively). 5112.30.30.00 serves as a residual category for all other woven fabrics classified under 5112.30 that do not fall into the specialized tapestry or upholstery fabric subheadings.
