8512.90.40.00 - Of a kind used on bicycles

This HTS category, 8512.90.40.00, specifically classifies parts of electrical lighting or signaling equipment that are designed and intended for use on bicycles. This designation encompasses a range of components that are integral to the lighting and signaling functions of a bicycle, such as bulbs, lenses, housings, mounting brackets, and electrical connectors that are uniquely adapted for bicycle applications. The critical determinant for classification under this subheading is the explicit "of a kind used on bicycles" criterion, indicating that these parts are not general-purpose components but rather are manufactured with the specific form, fit, and function required for integration into bicycle lighting and signaling systems.

Distinguishing this category from its sibling, 8512.90.60.00, which covers "Other" parts, is crucial. While 8512.90.60.00 would encompass parts for electrical lighting or signaling equipment used on motor vehicles or other general bicycle parts not directly related to lighting or signaling, 8512.90.40.00 is exclusively for those components that form part of the lighting or signaling apparatus on a bicycle. Therefore, if a part is intended for a bicycle's headlight, taillight, or indicator system, it will fall under this specific subheading, whereas general electrical components for a bicycle not related to lighting or signaling would likely be classified elsewhere.

As this is a leaf node within the HTS structure, there are no further subcategories to introduce. The classification concludes at this level based on the specific nature of the part and its intended application on bicycles. Classification into this subheading relies on the physical characteristics and evident utility of the part as being specifically suitable for bicycle lighting or signaling equipment, differentiating it from more generic or motor vehicle-specific counterparts.
