6115.96.90.10 - Containing 23 percent or more by weight of wool or fine animal hair (432)

This HTS category, 6115.96.90.10, specifically classifies knitted or crocheted hosiery items that contain 23 percent or more by weight of wool or fine animal hair. These items fall under the broader umbrella of "other" knitted or crocheted hosiery, excluding those with applied soles. The "containing 23 percent or more by weight of wool or fine animal hair" criterion is the key determinant for classification here, ensuring that garments predominantly made from natural animal fibers like sheep's wool or cashmere are correctly identified.

At this level, this subcategory is distinguished from its sibling, 6115.96.90.20, by the specific material composition. While both fall under "Other" synthetic fibers and then "Other," the 90.10 code exclusively applies to those hosiery items with a significant wool or fine animal hair content (23% or more by weight). The sibling category likely covers other synthetic fiber hosiery not meeting this specific wool/fine animal hair threshold.

As this is a leaf node, there are no further subcategories under 6115.96.90.10. Therefore, the classification is final for hosiery items meeting the outlined criteria of being knitted or crocheted, not footwear with applied soles, falling under "other" hosiery of synthetic fibers, and containing a substantial proportion of wool or fine animal hair by weight.
