6108.21.00 - Of cotton

This HTS category, 6108.21, specifically covers women's or girls' briefs and panties that are knitted or crocheted and made predominantly of cotton. These undergarments are designed for everyday wear and fall within the broader scope of intimate apparel and sleepwear for women and girls. The classification hinges on the garment's construction method (knitted or crocheted) and its primary constituent textile fiber.

Distinguishing this category from its siblings is crucial for accurate classification. HTS code 6108.22 covers similar briefs and panties made from man-made fibers, while 6108.29 encompasses those made from other textile materials not specifically listed in the preceding subcategories. Therefore, the defining characteristic of 6108.21 is its composition exclusively of cotton.

Within this category, further subdivisions exist to differentiate based on the intended wearer. Subcategory 6108.21.00.10 applies to women's briefs and panties, whereas 6108.21.00.20 is reserved for girls' versions. This distinction is important for trade statistics and compliance with any specific regulations or duties that may apply to these distinct demographic groups.
