8512.90.20.00 - Of signaling equipment

This HTS category, 8512.90.20.00, specifically covers parts and accessories for signaling equipment that fall under heading 8512. This includes components for audible signaling devices like horns, buzzers, and sirens, as well as visual signaling devices such as flashing lights or turn signals used on motor vehicles and cycles. The key distinguishing feature is their function solely as signaling apparatus, not as general lighting or de-icing equipment.

This category differentiates itself from its siblings by its exclusive focus on signaling functions. While "Parts: Of lighting equipment" (8512.90.10.00, though not explicitly listed as a sibling in the provided structure, it's implied within the parent description) would encompass parts for headlights, taillights, or interior illumination, and "Parts: Of defrosters and demisters" (8512.90.70.00) covers components for clearing windshields, this node is strictly for those parts integral to transmitting signals. The "Other" category (8512.90.90.00) serves as a residual for parts not specifically covered by the lighting, defrosting, or signaling designations.

As this node is a leaf node, there are no further subcategories. Therefore, classification into 8512.90.20.00 depends on a thorough assessment of the part's direct contribution to the signaling function of the complete equipment. For instance, a horn actuator, a flashing relay for a turn signal, or a siren speaker would all fall under this classification, provided they are designed for and exclusively used in signaling devices covered by heading 8512.
