6109.90.10.70 - Girls' (639)

This HTS category, 6109.90.10.70, specifically classifies knitted or crocheted tank tops and singlets for girls, crafted from man-made fibers. These garments are distinguished by their sleeveless design, intended for layering or warm-weather wear, and are made from synthetic or artificial fibers. The "girls'" designation differentiates these items from similar garments intended for women, as per specific trade and customs definitions of gender-specific apparel sizing and marketing.

Within the broader category of "Of man-made fibers: Women's or girls': Tank tops and singlets," this subcategory is distinct from its sibling, 6109.90.10.65, which covers the same type of garment but is designated for women. The primary criterion for distinguishing between these two is the intended recipient demographic and the associated sizing standards.

As this is a leaf node within the HTS structure, there are no further subdivisions. Therefore, the classification hinges on the precise material composition (man-made fibers) and the intended user (girls), alongside the garment type (tank top or singlet) and the manufacturing method (knitted or crocheted). Examples include children's athletic tank tops, casual sleeveless tops, and undershirts made from materials like polyester, nylon, or rayon.
