6112.39.00.15 - Containing 70 percent or more by weight of silk or silk waste (759)

This HTS subcategory, 6112.39.00.15, specifically classifies men's or boys' swimwear that is knitted or crocheted and is comprised of 70 percent or more by weight of silk or silk waste. This detailed material composition is the primary defining characteristic for items falling under this designation.

Distinguishing this category from its sibling, 6112.39.00.90, is crucial. While both fall under "Of other textile materials" for men's or boys' knitted or crocheted swimwear, category 6112.39.00.15 is strictly limited to garments where silk or silk waste constitutes the predominant fiber content (70% or more by weight). The sibling category, 6112.39.00.90, would encompass men's or boys' knitted or crocheted swimwear made from other textile materials that do not meet the specific silk content threshold of this classification.

As this node is a leaf node within the HTS classification, there are no further subcategories to introduce. Therefore, precise adherence to the material composition criteria, specifically the 70% or more silk or silk waste by weight requirement, is the sole determinant for classifying an item within 6112.39.00.15. This ensures that swimwear made predominantly from other "other textile materials" would be directed to the appropriate sibling category.
