6109.90.40.20 - Women's or girls' (739)

This HTS category, 6109.90.40.20, specifically classifies knitted or crocheted women's or girls' garments that fall under the broader description of t-shirts, singlets, tank tops, and similar items. These garments must be constructed from "other textile materials" and, crucially, contain 70 percent or more by weight of silk or silk waste. This emphasis on silk content is a primary determinant for inclusion within this particular subcategory.

The distinction from its sibling category, 6109.90.40.10, lies solely in the intended wearer. While both share the same garment type, textile material composition (other than silk, which is specifically covered here), and construction method, this node exclusively pertains to garments designed for women or girls. The sibling category, conversely, is for men's or boys' apparel.

As this node represents a leaf node in the HTS structure, there are no further subcategories to introduce. Classification at this level is definitive based on the garment type, knitted or crocheted construction, the use of "other textile materials," the substantial silk content (70% or more by weight), and the gender for whom the garment is intended. Examples of goods classified here would include silk knit tank tops, sleeveless shirts, or light t-shirts designed for women or girls.
