4012.90.70.00 - Bicycle rim strips

This HTS classification, 4012.90.70.00, specifically designates "bicycle rim strips" made of rubber. These are essential components fitted onto the inner circumference of bicycle rims to protect the inner tube from punctures caused by spoke nipples and to provide a cushioning layer. They are distinct from other types of rubber articles that might be found within Chapter 40, particularly those listed under heading 4012 which covers retreaded or used pneumatic tires, solid or cushion tires, tire treads, and tire flaps.

The "Other" classifications at this level (4012.90.90.00) are broader residual categories for rubber articles under heading 4012 that do not fit into the more specific subheadings for retreaded tires, solid tires, or tire treads and flaps. Therefore, bicycle rim strips are a distinct item due to their specific function and application in cycling, differentiating them from general rubber scrap or other unclassified rubber articles that might fall under the "Other" sibling category.

As this is a leaf node, there are no further subcategories. Classification at this level requires careful consideration of the product's intended use as a protective strip for bicycle rims, made from rubber. The physical characteristics and application are key to distinguishing these items from other rubber products within Chapter 40.
