6403.91.90.51 - Other 🖩

This HTS category, 6403.91.90.51, encompasses footwear that covers the ankle and has outer soles made of rubber, plastics, leather, or composition leather, with uppers constructed from leather. The "Other" designation at this level signifies that these items do not fit into more specific subdivisions within the broader category of leather footwear covering the ankle. This means the footwear is neither specifically designed for women nor children, but rather for "other persons," which typically includes men and potentially unisex designs not otherwise specified.

The key differentiator for this classification lies in its residual nature within the "covering the ankle" and "other footwear" brackets. If a piece of footwear made with a leather upper and an appropriate outer sole meets the criterion of covering the ankle, and it isn't explicitly categorized under a more specific sub-classification (such as for women or specific types of athletic footwear if those existed at lower levels), it will likely fall here. The emphasis remains on the material composition (leather upper, non-leather outer sole) and the ankle-covering feature.

As this is a leaf node in the HTS classification, there are no further subcategories to introduce. Classification at this level is definitive based on the absence of more specific criteria being met by the footwear in question. Therefore, a careful assessment of the physical characteristics and intended use of the footwear is crucial to ensure correct classification under this "other" category for persons not explicitly defined elsewhere.
