6211.12 - Women's or girls':

This HTS category, 6211.12, specifically covers swimwear for women and girls. This includes garments designed for swimming, bathing, or sunbathing, such as bikinis, one-piece swimsuits, tankinis, and swim trunks or shorts when designed and marketed for female wearers. The primary characteristic defining this classification is its intended use for aquatic activities and its design catering to women's and girls' sizing and styles.

This category is distinct from its sibling, 6211.11, which covers men's or boys' swimwear. While both fall under the broader umbrella of swimwear, the crucial differentiator is the intended gender of the wearer, which dictates design, sizing, and cut. Therefore, a garment intended for a male wearer would be classified under 6211.11, regardless of material or construction.

The subcategories within 6211.12 provide further refinement based on the primary fiber content. Subcategory 6211.12.10 addresses swimwear predominantly made from man-made fibers, which are common in modern swimwear for their elasticity and water-resistance. 6211.12.40.00 specifically addresses swimwear where silk or silk waste constitutes 70 percent or more by weight, a more niche but distinct material classification. Finally, 6211.12.80 serves as a catch-all for swimwear not otherwise specified, typically encompassing garments made from other natural or blended fibers.
