6106.90.10 - Of wool or fine animal hair

This HTS category, 6106.90.10, encompasses knitted or crocheted blouses and shirts specifically made from wool or fine animal hair. These garments fall under Section XI, focusing on textile articles, and specifically Chapter 61, which deals with knitted or crocheted apparel. The "fine animal hair" designation typically includes materials like cashmere, angora, mohair, alpaca, llama, and vicuña, differentiating these items from those made of coarser wools or other textile fibers.

Within the broader category of "Women's or girls' blouses and shirts, knitted or crocheted: Of other textile materials," this subcategory is distinguished by its exclusive focus on wool and fine animal hair. Siblings in this context would represent blouses and shirts made from different primary materials, such as silk (6106.90.05) or other unspecified textile materials (6106.90.30). The key differentiator for 6106.90.10 is the inherent nature and origin of the animal-based fibers used in their construction.

Further classification within this category is achieved by distinguishing between garments intended for women and those for girls. Subcategories 6106.90.10.10 and 6106.90.10.20 are provided to delineate these two distinct groups, allowing for more precise tracking and tariff application based on the intended wearer. This subdivision acknowledges the typical differences in sizing and styling that distinguish women's apparel from that designed for younger females.
