6211.39.60 - Containing 70 percent or more by weight of silk or silk waste

This HTS category, 6211.39.60, specifically covers men's or boys' garments that are not knitted or crocheted and are made from textile materials other than wool or fine animal hair. The defining characteristic of this subcategory is that the garments must contain 70 percent or more by weight of silk or silk waste. This material composition is the primary criterion for distinguishing these items from other categories within heading 6211.

Compared to its sibling category 6211.39.30, which pertains to garments of wool or fine animal hair, this classification focuses exclusively on silk-based textiles. It also differs from the sibling 6211.39.80, which encompasses "other" garments made of textile materials not otherwise specified within this section. Therefore, the silk content is the crucial factor in correctly classifying an item under 6211.39.60.

Within this category, further subdivisions exist to refine the classification based on the specific type of garment. These subcategories, such as track suits, shirts excluded from heading 6205, vests, jackets, and other apparel like coveralls, jumpsuits, washsuits, and sunsuits, provide more granular distinctions. The selection of the appropriate subcategory will depend on the garment's design, intended use, and specific construction, ensuring precise tariff application.
