6110.90.90.66 - Women's or girls' (859)

This HTS classification, 6110.90.90.66, specifically covers women's or girls' knitted or crocheted vests that are not sweater vests. These garments are distinct from other knitted or crocheted vests by their intended wearer and material composition, falling under the broader category of "Of other textile materials." The "Other" designation at this level indicates that these vests are not constructed from the specific textile materials detailed in preceding subheadings within the "Of other textile materials" grouping.

This category is differentiated from its sibling, 6110.90.90.64, which classifies similar knitted or crocheted vests but is designated for men's or boys' wear. Therefore, the primary distinguishing factor between these two subheadings is the gender of the intended wearer. As a leaf node in the HTS structure, 6110.90.90.66 does not have further subcategories, meaning all items meeting these criteria are classified directly under this code. Examples within this classification would include knitted or crocheted sleeveless garments designed for women or girls, serving as outerwear or layering pieces, but lacking the full construction and typical appearance of a sweater.
