This HTS classification, 9902.14.56, specifically covers detachable gravel guards designed for footwear. These guards are characterized by their construction, featuring uppers made of 3 mm neoprene with a nylon jersey face and underside. Key physical dimensions include a height measuring 17.78 cm or more but not exceeding 20.32 cm, and a tapered fit. Their functional design includes a hook-and-loop fastener strip and a loop wrap for secure attachment to the shoe, distinguishing them from integrated shoe components.

Given that this is a specific provision within Chapter 99, its primary function is to address temporary legislation or specific trade policy measures related to these particular gravel guards. Unlike the broader categories found in Chapters 01 through 98 which classify a vast array of general merchandise based on material and function, this 9902 code targets a niche item for specific regulatory purposes. Therefore, distinctions from sibling categories are less about direct product comparison and more about recognizing the special, temporary nature of this classification within the overall HTS structure.

As this node represents a leaf node within the HTS database, there are no further subcategories for this specific classification. The detailed description provided accurately defines the precise parameters of the goods covered, and classification would hinge on meeting all enumerated physical characteristics and functional attributes.
