6110.90.90.90 - Women's or girls' (838)

This HTS subheading, 6110.90.90.90, specifically classifies women's or girls' knitted or crocheted sweaters, pullovers, sweatshirts, waistcoats (vests), and similar articles that are made from textile materials other than those explicitly enumerated in preceding subheadings. The term "other textile materials" here refers to fibers and yarns not specifically covered by categories like cotton, synthetic fibers, or fine animal hair, and the final "other" designations indicate that these articles are not specifically detailed elsewhere within the broader headings for similar garments.

The critical distinguishing factor for this category is its focus on "Women's or girls'" apparel. Its direct sibling, 6110.90.90.88, covers identical garment types but for "Men's or boys'." Therefore, the primary classification criterion here is the intended wearer. If a garment fits the description of a sweater, pullover, or similar knitted/crocheted item, is not made of the explicitly detailed textile materials, and is designed for female wearers, it will fall under this specific subheading.

As this subheading is a leaf node, it represents the most granular level of classification for this particular type of garment. Consequently, there are no further subcategories to introduce. Classification at this level relies on accurately identifying the garment type, confirming it is knitted or crocheted, verifying it's not made from specifically listed textile materials, and most importantly, confirming the intended gender of the wearer.
