6108.99.50.13 - Underwear (752)

This HTS category, 6108.99.50.13, specifically covers knitted or crocheted women's or girls' underwear that is predominantly made of silk. This includes garments such as briefs, panties, and other similar intimate apparel where silk or silk waste constitutes 70 percent or more of the total weight of the textile material. The "Underwear (752)" designation in the description further clarifies the specific type of garment within the broader category of knitted or crocheted women's slips, petticoats, night dresses, pajamas, and similar articles.

This classification is distinguished from its sibling, 6108.99.50.15 "Other," by its precise material composition. While both fall under "Of other textile materials," category .13 mandates a significant silk content (70% or more by weight), whereas category .15 would encompass other knitted or crocheted women's intimate apparel made from various textile materials that do not meet the specific silk threshold.

As this is a leaf node, there are no further subcategories. Therefore, the primary focus for classification under this code is the careful verification of the garment's type (women's or girls' underwear) and the accurate determination of its material composition to confirm it contains 70 percent or more by weight of silk or silk waste. This ensures correct duty assessment and trade compliance for these specific silk-based intimate apparel items.
