6403.91.90.15 - Work footwear

This HTS subcategory, HTS 6403.91.90.15, specifically classifies "Work footwear" that covers the ankle. These are durable shoes designed for occupational use, offering protection and support in various working environments. The defining characteristic is their ankle-high construction, intended to provide added stability and defense against hazards common in industries such as construction, manufacturing, and agriculture.

Within the broader category of "Other footwear" under "Footwear with outer soles of rubber, plastics, leather or composition leather and uppers of leather," this subcategory differentiates itself by its intended purpose. While other "Other" footwear might be casual or fashion-oriented, work footwear is functionally driven. The inclusion of "covering the ankle" further narrows the scope, distinguishing it from ankle boots or other footwear that does not extend to or above the ankle bone.

As a leaf node, HTS 6403.91.90.15 represents a specific and terminal classification. Therefore, there are no further subdivisions. Classification into this category hinges on the item being footwear with leather uppers and a sole of rubber, plastics, leather, or composition leather, designed for work, and extending to cover the ankle. Common examples include steel-toed boots, safety boots, and durable boots utilized in demanding professions.
