6402.91.50.20 - Other

This HTS classification covers footwear specifically designed to be worn over existing footwear, or in place of it, to provide protection. The primary protective functions include shielding against water, oil, grease, chemicals, or harsh cold or inclement weather. These are typically robust, utilitarian items intended for specialized protective use rather than everyday fashion or general comfort.

This category is distinguished from its sibling, "Work footwear" (6402.91.50.10), by its explicit design and primary purpose of offering a protective outer layer. While work footwear may incorporate protective features, this classification is exclusively for items intended to be worn *over* or *in lieu of* other footwear specifically for environmental or chemical protection. The emphasis here is on a secondary layer of defense against hazardous conditions.

As this is a leaf node, there are no further subdivisions within this HTS code. Therefore, classification at this level relies on the precise determination that the footwear meets the criteria of being a protective outer layer designed for specific environmental hazards, and that it is intended for men. Examples may include chemical-resistant overboots, waterproof galoshes designed for extreme weather, or insulated booties for industrial cold-storage environments.
