6403.51.60.60 - Other

This HTS category, 6403.51.60.60, specifically classifies "Other" footwear that meets the preceding criteria for outer soles of leather and uppers of leather, covering the ankle, and falling under the "Other" subcategory for footwear that isn't otherwise specified. The inclusion of "Other" at this detailed level indicates a residual classification for items that do not fit into more precisely defined sub-classifications within the broader categories of men's, youth's, and boys' footwear.

The key differentiating factor for this specific subcategory, "For men, youths and boys," is the intended wearer. While the material and construction requirements (leather outer soles and uppers, ankle-covering) are shared with other classifications, the final designation here is for footwear designed for male individuals of all ages. It is crucial to distinguish this from sibling categories that may classify similar footwear but are intended for different demographic groups or have slightly different functional attributes not captured by the "Other" designation.

As this is a leaf node within the HTS structure, there are no further subcategories. Therefore, the classification ends at this point, with 6403.51.60.60 serving as the final designation for these specific types of men's, youth's, and boys' footwear. Practical application will require careful assessment to ensure the footwear indeed possesses leather outer soles and leather uppers, covers the ankle, and does not fit into any more specific tariff lines that may exist at higher levels.
