6406.10.90.20 - Of wool or fine animal hair (469)

This HTS subcategory, 6406.10.90.20, specifically classifies uppers and parts of uppers for footwear that are made of wool or fine animal hair. This includes components such as the main body of the shoe's upper, excluding stiffeners, when constructed from these natural animal fibers. Examples would be the knitted or woven wool sections that form the upper of a slipper or a boot.

It is crucial to differentiate this category from its siblings. Unlike subcategory 6406.10.90.40, which pertains to uppers made of man-made fibers, this classification exclusively applies to natural animal hair materials like wool, cashmere, or alpaca. Subcategory 6406.10.90.60, "Other," serves as a residual category and should only be used when the material does not fit into the specific categories for cotton, man-made fibers, or wool/fine animal hair.

As this is a leaf node, there are no further subdivisions. Therefore, the classification hinges entirely on the accurate identification of the material as wool or fine animal hair. This ensures that footwear uppers composed of these specific natural fibers are correctly accounted for in trade statistics and customs procedures.
