Overview
This HTS category, 6403.91, specifically addresses footwear that covers the ankle and features outer soles made from rubber, plastics, leather, or composition leather, with uppers constructed from leather. The defining characteristic here is the ankle-covering height of the footwear, distinguishing it from lower-cut shoes within the same broader chapter. This classification is part of a hierarchy focused on footwear with specific sole materials and, in this instance, leather uppers.
Within the "Other footwear" grouping under 6403, this category is differentiated from its sibling, 6403.99, by the explicit requirement that the footwear must cover the ankle. While 6403.99 encompasses all other leather-upper footwear with the specified outer soles that do *not* cover the ankle, 6403.91 is strictly for those that do. This distinction is crucial for accurate tariff application, as it isolates a particular style and height of footwear.
The subcategories under 6403.91 further refine the classification based on specific construction or features. For instance, 6403.91.11.00 accounts for footwear constructed on a wooden base or platform, with the absence of an inner sole or a protective metal toe-cap being key identifiers. The subsequent "Other" subcategory within 6403.91 would capture any remaining ankle-covering leather footwear meeting the general criteria but not falling into the more specific defined sub-classifications.
