6107.99.50.13 - Sleepwear (751)

This HTS category, 6107.99.50.13, encompasses sleepwear specifically crafted from textile materials where silk or silk waste constitutes 70 percent or more of the total weight. This includes items like pajamas, nightshirts, and other similar garments designed for sleeping or lounging, provided they are knitted or crocheted. The emphasis on a high silk content is a key defining characteristic for classification within this specific sub-heading.

Within the broader category of "Of other textile materials," this sub-heading is distinguished from its sibling, 6107.99.50.15, which covers "Other" sleepwear of other textile materials that do not meet the 70% silk or silk waste threshold. Therefore, classification here hinges directly on the precise material composition, requiring precise weight analysis to confirm the silk percentage.

As a leaf node in the HTS classification system, this category does not have further subdivisions. Goods classified under 6107.99.50.13 will be considered final for customs purposes, provided they meet all the criteria for men's or boys' sleepwear, are knitted or crocheted, and are predominantly composed of silk or silk waste.
