6109.90.10.50 - Women's (639)

This HTS category, 6109.90.10.50, specifically classifies women's t-shirts, singlets, tank tops, and similar garments that are knitted or crocheted, and are made from man-made fibers. These items fall under the broader classification of "T-shirts, singlets, tank tops and similar garments, knitted or crocheted: Of other textile materials: Of man-made fibers."

This classification distinguishes itself from its sibling category, 6109.90.10.60, by focusing exclusively on garments intended for women. While both categories cover knitted or crocheted apparel made from man-made fibers, the crucial differentiator is the target demographic. This specific code is for women's wear, whereas the sibling code is for girls' wear.

As this is a leaf node within the HTS structure, there are no further subcategories under 6109.90.10.50. Therefore, the classification is complete at this level, encompassing all women's knitted or crocheted t-shirts, singlets, tank tops, and similar garments made from man-made fibers, without further subdivision based on style, specific material composition within man-made fibers, or any other characteristic.
