9506.70.20.90 - Other

This HTS category, 9506.70.20.90, covers "Other" roller skates and their associated parts and accessories that are not explicitly defined by other subheadings within the 9506.70.20.00 range. It serves as a residual category for roller skates that do not fall under the more specific classifications, particularly distinguishing itself from roller skates or their components that are already attached to boots, which are classified under 9506.70.20.10.

The primary distinction for classification within this subheading lies in whether the roller skate or its parts are intrinsically integrated with footwear. If the roller skate unit is separate from a boot or shoe, or if the parts are standalone components intended for attachment to non-boot-integrated skates, they will generally be classified here. This encompasses a wide array of roller skate types, including quad skates, inline skates (where the boot is not an integral part of the skate assembly), and replacement wheels, bearings, frames, and stoppers that are not specifically designed to be permanently affixed to a boot.

As this is a leaf node in the HTS structure, there are no further subcategories. Therefore, the classification hinges on a thorough examination of the product's physical characteristics and intended use, ensuring it aligns with the broader scope of "roller skates and parts and accessories thereof" while excluding items specifically designated for other subheadings.
