8507.90.80.00 - Other

This classification, HTS 8507.90.80.00, covers miscellaneous parts for electric storage batteries that are not specifically classified elsewhere. It encompasses components and accessories for a broad range of electric storage batteries, excluding those explicitly detailed in other subheadings. Examples of items that might fall under this designation include housings, terminals, connectors, internal structural components not made of lead-acid battery materials, and other miscellaneous parts.

This category serves as a residual for battery parts, distinguishing itself from its sibling category, 8507.90.40.00, which specifically enumerates parts *of lead-acid storage batteries*. Therefore, if a part is intended for a lead-acid battery, it would be classified under 8507.90.40.00. Conversely, HTS 8507.90.80.00 would apply to parts of other types of electric storage batteries, such as nickel-cadmium, nickel-metal hydride, lithium-ion, or other non-lead-acid formulations, provided they do not fit into a more specific subheading.

As this is a leaf node, there are no further subdivisions within this category. Classification into HTS 8507.90.80.00 is therefore determined by the exclusion of the part from more specific categories and its direct relationship as a component or accessory to an electric storage battery. The key determining factor is that the part is not specifically enumerated elsewhere and is clearly intended for use with electric storage batteries other than lead-acid types.
