6204.31.10 - Containing 30 percent or more by weight of silk or silk waste

This HTS classification, 6204.31.10, specifically covers suit-type jackets and blazers for women or girls that are composed of 30 percent or more by weight of silk or silk waste. These garments are designed to be part of a suit or ensemble, embodying a more formal or structured aesthetic. The defining characteristic for inclusion in this category is the significant silk content, which dictates its material composition and often implies a certain quality and drape.

Distinguishing this category from its sibling, 6204.31.20 (Other), is crucial. While 6204.31.20 would encompass suit-type jackets and blazers of wool or fine animal hair that do not meet the silk content requirement, 6204.31.10 is exclusively for those garments where silk or silk waste is the primary fibrous component by weight. This distinction is fundamental for accurate tariff assessment based on material.

This category further subdivides into 6204.31.10.10 for women's garments and 6204.31.10.20 for girls' garments. This differentiation is based on the intended wearer and associated sizing and design considerations. The presence of these subcategories allows for more granular classification within the broader category of silk-content suit-type jackets and blazers.
