6117.90.10.40 - Of trousers, breeches and shorts (748)

This HTS category, 6117.90.10.40, specifically classifies knitted or crocheted parts intended for the assembly or repair of trousers, breeches, and shorts. These components are made from materials where silk or silk waste constitutes 70 percent or more by weight. Examples include knitted waistbands, pockets, leg panels, or decorative elements that are integral to the construction of these lower body garments.

It is crucial to distinguish this category from its siblings. For instance, 6117.90.10.10 covers parts for knitted or crocheted sweaters, while 6117.90.10.20 pertains to parts for blouses and shirts. Similarly, 6117.90.10.30 is for parts of knitted or crocheted coats and jackets. This category's defining characteristic, beyond being a "part," is its specific application to trousers, breeches, and shorts, coupled with the high silk content requirement.

As this is a leaf node within the HTS structure, there are no further subcategories for trousers, breeches, and shorts parts under this specific silk-content provision. Classification at this level is determined by the garment type (trousers, breeches, shorts) and the predominant material composition (70% or more silk/silk waste) for the knitted or crocheted part.
