6403.19.40.90 - Other

This HTS category, 6403.19.40.90, encompasses "Other" sports footwear where the outer soles are made of rubber, plastics, leather, or composition leather, and the uppers are constructed from leather. This designation is applied to sports footwear that does not fit into more specific subcategories within the broader heading 6403.19, which deals with sports footwear other than ski-boots, cross-country ski footwear, and beach footwear.

The critical distinction for this "Other" classification lies in its residual nature. It serves as a catch-all for sports footwear meeting the general material criteria but lacking the specific attributes that would place them in a more precisely defined sibling category, such as footwear with pigskin uppers (6403.19.40.30). Therefore, classification here requires a careful review to ensure the footwear is indeed intended for sports and does not possess any unique characteristics that would warrant placement in a more granular subheading, if such existed.

As this node is a leaf node within the HTS structure, there are no further subcategories. The classification is finalized at this level based on the defined material composition of the outer sole and upper, and its specific exclusion from other defined sports footwear categories. This means that the determination hinges on the absence of characteristics that would place it into a more specialized classification, making it crucial to thoroughly assess the footwear against all applicable subheadings within heading 6403.19.
