6406.90.15.05 - Containing 23 percent or more by weight of wool or fine animal hair (459)

This HTS category, 6406.90.15.05, specifically covers leg-warmers that are made of textile materials, and further, are composed of man-made fibers. The defining characteristic for this subcategory is that these leg-warmers must contain 23 percent or more by weight of wool or fine animal hair. This precise material composition is the key determinant for classification under this heading.

Distinguishing this category from its sibling, 6406.90.15.10 "Other," is crucial. While both fall under "Of textile materials" and "Of man-made fibers," the sibling category is for leg-warmers that *do not* meet the specific wool or fine animal hair content requirement of 23 percent or more. Therefore, if a leg-warmer is predominantly made of man-made fibers but has a negligible amount of wool or fine animal hair, or none at all, it would fall into the "Other" category.

As a leaf node, this classification does not have further subdivisions. The classification is complete at this level, with the primary focus being on the material composition of the leg-warmers. Importers and exporters should carefully verify the weight percentage of wool or fine animal hair in their man-made fiber leg-warmers to ensure accurate classification.
