6217.90.10.30 - Of trousers and breeches (748)

This HTS classification, 6217.90.10.30, specifically designates parts of garments and clothing accessories that are made up, but not knitted or crocheted, and that contain 70 percent or more by weight of silk or silk waste. The "parts" in this context refer to components that, when assembled, form complete garments such as trousers and breeches. These parts must be specifically intended for use in the construction of these lower-body garments, distinguishing them from other garment components.

Unlike sibling categories such as 6217.90.10.10 (for blouses and shirts) or 6217.90.10.20 (for coats and jackets), this classification is exclusively for parts destined for trousers and breeches. The broad "Other" category (6217.90.10.60) would encompass parts for other types of garments or accessories not explicitly listed in the preceding subheadings. The material composition, requiring a substantial silk content, is a critical determinant for inclusion here, aligning with the broader scope of Chapter 62 which often differentiates based on fiber content.

As a leaf node, this category does not have further subdivisions. Classification within 6217.90.10.30 therefore relies directly on the physical characteristics of the part, its intended use in trousers and breeches, and confirmation of its silk content meeting the 70% or greater threshold by weight. Examples of such parts could include silk waistbands, silk pockets, or silk leg panels specifically cut and prepared for the assembly of silk trousers.
