6402.99.33.10 - Work footwear

This HTS classification covers protective footwear specifically designed to be worn over existing footwear or as a replacement for them, offering protection against environmental hazards. The primary purpose is safeguarding the wearer's feet and conventional footwear from water, oil, grease, chemicals, or extreme cold and inclement weather conditions. Examples include overshoes, galoshes, or chemical-resistant boots intended for industrial or outdoor use where standard footwear would be inadequate or susceptible to damage.

Within the broader category of "Other footwear with outer soles and uppers of rubber or plastics," this subcategory distinguishes itself by its specific protective function. Unlike general-purpose rubber or plastic footwear, the items classified here are explicitly engineered for adverse environmental or hazardous material exposure. The sibling category, "Other," at this level would encompass rubber or plastic footwear that does not fall into the defined protective categories.

As this is a leaf node, there are no further subcategories. Classification at this level relies on a thorough assessment of the footwear's intended use and protective features. Key considerations include the materials used in the sole and upper, which must be of rubber or plastic, and the design features that facilitate the protection against water, oil, grease, chemicals, or extreme weather, such as elevated cuffs, watertight seals, and robust material construction.
