6403.91.30.91 - Other

This HTS code, 6403.91.30.91, encompasses "Other" footwear that covers the ankle and is constructed with outer soles of rubber, plastics, leather, or composition leather, and uppers of leather. Specifically, it falls under the broader category of "Other footwear" within the classification for footwear with leather uppers and non-textile soles. The key defining characteristic for this subcategory is its construction method, referring to "welt footwear." Welt construction involves a strip of material (the welt) sewn to the upper and the sole, creating a durable and flexible bond often associated with higher-quality footwear.

This category is distinguished from its sibling category, 6403.91.30.80 ("For women"), by its intended consumer demographic. While both share the same construction and material criteria, this specific code applies to welt footwear covering the ankle with leather uppers and non-textile soles that are not specifically designed for women. This typically implies footwear intended for men or unisex designs that do not fit the specific criteria for women's footwear.

As a leaf node in the HTS classification, 6403.91.30.91 does not have further subcategories. Therefore, classification within this code requires careful consideration of all preceding criteria. Importers must ensure the footwear features outer soles made from rubber, plastics, leather, or composition leather, has uppers primarily made of leather, extends to cover the ankle, and is manufactured using the welt construction method. The absence of specific gender designation further solidifies its placement under this "Other" designation within welt footwear.
