6402.99.31.55 - Work footwear

This HTS classification, 6402.99.31.55, specifically covers "Work footwear" with outer soles and uppers made primarily of rubber or plastics. This category is reserved for footwear designed for occupational use, implying features that provide protection, durability, or specialized functionality required for various work environments. Such footwear is distinguished by its robust construction and often incorporates elements like reinforced toes, slip-resistant soles, or chemical resistance, differentiating it from general-purpose footwear.

While the broader category of "Other footwear" with rubber or plastic uppers is vast, this subcategory narrows the focus to footwear intended for employment. It stands apart from potential sibling categories at this level by its specific designation as "Work footwear." This implies that general-purpose footwear with similar material composition but lacking occupational features would fall under a different classification. The classification hinges on the intended use and the inherent characteristics that support that use in a professional or industrial setting.

As this classification is a leaf node, there are no further subdivisions. Therefore, the classification relies entirely on correctly identifying the footwear as "Work footwear" based on its design, intended purpose, and material composition, adhering to the specific criteria outlined in the preceding levels of the Harmonized Tariff Schedule. Examples may include safety boots, industrial clogs, or specialized footwear designed for agriculture or construction.
