6401.92.30.00 - Ski-boots and snowboard boots

This HTS category, 6401.92.30.00, specifically classifies ski-boots and snowboard boots that are waterproof and constructed with outer soles and uppers made from rubber or plastics. A key defining characteristic of footwear within this heading is that the uppers are not permanently affixed to the sole through traditional assembly methods such as stitching, riveting, nailing, screwing, or plugging. Instead, the construction relies on other methods that maintain the waterproof integrity without these specific assembly techniques.

While the parent category covers a broad range of waterproof footwear, this specific subcategory, "Covering the ankle but not covering the knee," narrows the scope further. It distinguishes these boots from other waterproof footwear that might not cover the ankle or that extend further up the leg to cover the knee. The sibling category, ": Other:", would encompass waterproof footwear constructed with rubber or plastic uppers and soles, where the uppers are not assembled by the specified methods, but which do not fit the specific criteria of covering the ankle but not the knee, or other more specific sub-classifications within 6401.92.

As this is a leaf node, there are no further subdivisions. Therefore, the focus for classification under 6401.92.30.00 is on confirming that the item is indeed a ski-boot or snowboard boot meeting the waterproof criteria and the specific assembly method exclusion for the uppers. Practical considerations for classification would include examining the footwear's design, intended use for snow sports, and the method by which the upper is attached to the sole to ensure it is not one of the prohibited methods.
