6103.49.10.20 - Trousers and breeches (647)

This HTS classification covers knitted or crocheted trousers and breeches specifically for men or boys, manufactured from textile materials other than cotton, wool, or fine animal hair, and not of artificial fibers. The designation "trousers and breeches" in this context refers to garments that extend from the waist or hips down to the ankles or just below the knee, designed for the lower body.

Distinguishing this category from its sibling, 6103.49.10.60, is crucial. While both fall under "Of other textile materials" and "Of artificial fibers" within the broader "Trousers, bib and brace overalls, breeches and shorts" heading, this specific code, 6103.49.10.20, is designated for "Trousers and breeches." The sibling category, 6103.49.10.60, exclusively covers "Shorts," which are typically garments extending only to the thigh.

As this is a leaf node, there are no further subcategories for this specific classification. Therefore, the primary classification challenge lies in accurately identifying trousers and breeches made from artificial fibers and differentiating them from shorts, as well as ensuring they are not excluded by the parent categories pertaining to natural fibers.
