6402.91.10.00 - Footwear designed to be worn over, or in lieu of, other footwear as a protection against water, oil, grease or chemicals or cold or inclement weather 🖩

This HTS classification, 6402.91.10.00, encompasses footwear specifically designed as protective gear worn over or in place of standard footwear. The primary function of these items is to shield the wearer's feet and lower legs from specific environmental hazards. This includes protection against water, oils, greases, and various chemicals, as well as safeguarding against cold or inclement weather conditions. The construction typically involves outer soles and uppers made from rubber or plastics.

Within the broader category of "Other footwear, covering the ankle," this classification is distinguished by its explicit protective purpose. While other footwear might incidentally offer some protection, items classified here are intentionally engineered for a primary protective function against defined risks. This level of footwear specifically covers the ankle, differentiating it from lower-cut protective footwear that might fall under different subheadings.

As this is a leaf node within the HTS structure, there are no further subcategories. Therefore, classification into this specific code hinges entirely on meeting the criteria of being an over- or replacement-footwear item, offering protection against the stipulated elements (water, oil, grease, chemicals, or weather), having rubber or plastic outer soles and uppers, and extending to cover the ankle. Examples would include chemical-resistant overshoes, insulated waterproof boots designed for extreme weather, or oil-resistant galley shoes.
