8511.90.40.00 - Other

This HTS category, 8511.90.40.00, encompasses "Other" parts for electrical ignition or starting equipment for internal combustion engines, and generators and cut-outs used with such engines. Specifically, it captures components that fall within the scope of heading 8511 but are not explicitly listed or defined in more specific subcategories. This includes a wide array of parts such as housings, fasteners, small electrical components, or specialized items not fitting into other designated part categories.

This classification is distinguished from its sibling, 8511.90.20.00, by its broader scope. While 8511.90.20.00 is reserved for parts specifically designed for use on 6, 12, or 24-volt systems, this "Other" category covers all remaining parts of heading 8511 that do not meet that voltage-specific criterion or any other more granular classification. The key differentiator lies in the absence of a specific voltage designation for the parts classified here.

As a leaf node, 8511.90.40.00 does not have further subcategories. Therefore, the focus for classification within this code is on ensuring that the part in question is indeed a component of the machinery described in heading 8511 and does not fit into any more precisely defined subcategories based on material, function, or voltage. Careful examination of the part's design, intended application, and overall role within the ignition, starting, or generating system is crucial for correct classification.
