6404.11.90.70 - Ski boots, cross country ski footwear and snowboard boots

This HTS category specifically covers specialized athletic footwear designed for snow sports. It includes ski boots, which are rigid or semi-rigid footwear designed to secure the foot and lower leg for skiing, and cross-country ski footwear, which is generally more flexible than downhill ski boots. Additionally, snowboard boots, which are designed to interface with snowboard bindings, are also classified here. The key unifying characteristic is their design for specific snow-based recreational activities.

This classification is distinct from its sibling category, 6404.11.90.80, which is designated for "Other" footwear at this level. While the broad category encompasses sports footwear, this specific line item (6404.11.90.70) carves out a niche for the aforementioned snow sports boots, implying a more specific set of design features and intended uses compared to general "other" sports footwear.

As this is a leaf node within the HTS structure, there are no further subcategories for this specific code. Therefore, the classification is final for items fitting this description and meeting the value threshold of over $12 per pair. Classification decisions at this level rely heavily on the precise intended use of the footwear, its construction, and its material composition to ensure accurate determination for customs purposes.
