6204.63.75.10 - Ski/snowboard pants (648)

This category specifically classifies water-resistant trousers and breeches designed for ski or snowboard use. The key determinant for inclusion here is the water-resistant property, which is crucial for outdoor winter sports apparel. These garments are typically constructed from synthetic fibers and are intended to protect the wearer from moisture and cold during activities like skiing or snowboarding. The "(648)" designation in the description likely refers to an internal note or specific ruling relevant to this classification.

Distinguishing this from its sibling, 6204.63.75.90 "Other," this category is for items that possess the explicit characteristic of water resistance. The "Other" category at this level would encompass water-resistant trousers and breeches made of synthetic fibers that do not fit into any more specific sub-classifications, or non-water-resistant items. However, the presence of this dedicated "Water resistant trousers or breeches" code indicates a specific intent for these types of garments.

As this is a leaf node, there are no further subcategories to introduce. Therefore, classification professionals should focus on confirming the water-resistant nature of the trousers or breeches, ensuring they are made of synthetic fibers, and verifying their intended use for skiing or snowboarding to accurately apply this HTS code.
