6406.10.90 - Other

This classification, HTS Code 6406.10.90, encompasses "Other" parts of footwear that fall under the broader category of "Uppers and parts thereof, other than stiffeners." This specifically refers to components of shoe uppers that are not stiffeners and do not fit into more narrowly defined subcategories within the "Other" classification at this level. It represents a residual category for upper parts that are not predominantly textile or specific types of textile uppers.

The primary distinction of this category from its sibling, 6406.10.85.00, lies in the material composition of the external surface area. While 6406.10.85.00 exclusively covers uppers where less than 50 percent of the external surface is textile materials, HTS Code 6406.10.90 is for those that do not meet this specific textile-based criterion, or are not otherwise explicitly defined. This implies a focus on non-textile dominant materials or combinations thereof for the external components of the upper.

Within this "Other" category, a further subdivision exists to refine classifications based on material. The subcategory 6406.10.90.90, also designated as "Other," serves to capture remaining upper parts that fall under the general "Other" classification but require further distinction, particularly those made of textile materials other than cotton. This hierarchical structure allows for precise classification of diverse footwear components.
