4012.90.30.00 - Bicycle rim strips

This HTS subheading, 4012.90.30.00, specifically classifies bicycle rim strips made of rubber. These are typically the protective bands or liners that are inserted between the inner tube and the rim of a bicycle wheel. Their primary function is to prevent the inner tube from being punctured by spoke ends or sharp edges on the rim. The classification is based on the material composition of natural rubber and the specific application as a component for bicycle wheel assemblies.

At this level of detail, the distinction from sibling category 4012.90.45.00, which covers "Other" retreaded or used tires and tire parts not otherwise specified, is crucial. While both fall under the broader category of "Other" rubber articles from used tires or tire parts, 4012.90.30.00 is a highly specific classification for a particular bicycle component, whereas 4012.90.45.00 serves as a residual category for other miscellaneous rubber items within this section. The specificity of "bicycle rim strips" differentiates it from more general rubber components or repairs.

As this subheading represents a leaf node within the HTS structure, there are no further subcategories for this classification. Therefore, the focus remains on precisely identifying and classifying bicycle rim strips made of natural rubber according to their distinct characteristics and intended use, ensuring accurate customs processing.
