6112.49.00.15 - Containing 70 percent or more by weight of silk or silk waste (759)

This HTS category, 6112.49.00.15, specifically classifies women's or girls' swimwear that is knitted or crocheted and is composed of other textile materials. The defining characteristic of this particular subcategory is that the garment must contain 70 percent or more by weight of silk or silk waste. This emphasis on silk content is crucial for accurate classification, differentiating it from other swimwear made from different or blended textile materials.

Within the broader category of "Women's or girls' swimwear: Of other textile materials," this HTS code stands apart from its sibling, 6112.49.00.90, which covers all other women's or girls' swimwear made from textile materials not meeting the specific silk percentage requirement. Therefore, if a garment is not primarily silk (70% or more by weight), it would fall under the "Other" sibling category.

As this is a leaf node in the HTS structure, there are no further subcategories. Classification under 6112.49.00.15 is conclusive when the garment meets the criteria of being knitted or crocheted women's or girls' swimwear, made from textile materials other than primary synthetic or cellulosic fibers, and predominantly (70% or more by weight) composed of silk or silk waste.
