6505.00.90.45 - Of fine animal hair (459)

This HTS classification, 6505.00.90.45, specifically covers headgear that is knitted or crocheted, or otherwise constructed from textile materials, and is distinguished by its composition of fine animal hair. This includes items like hats, caps, bonnets, and other head coverings that fall under the broader category of Chapter 65, but are not made from lace, felt, or paper yarn. The "fine animal hair" designation is crucial for classification, referring to materials such as cashmere, angora, vicuña, or fine wools, as opposed to coarser animal fibers.

This specific subcategory differentiates itself from its sibling, 6505.00.90.50, which is designated for headgear constructed from paper yarn. While both are "other" constructions within the broader knitted or crocheted headgear chapter, the material content is the defining factor. If a headgear is made primarily from fine animal hair, it will fall under this 45 designation; if it's predominantly from paper yarn, it will be classified under the 50 designation.

As this is a leaf node within the HTS structure, there are no further subcategories to introduce. Therefore, classification within 6505.00.90.45 relies solely on confirming that the headgear is knitted or crocheted, or made up from textile fabric (but not in strips), is lined or trimmed as permitted, and is indeed composed of fine animal hair. The context of Chapter 65, covering all types of headgear and their parts, provides the overarching framework for this specific material-based distinction.
