Parts for Electrical Ignition & Starting Equipment and Generators for Internal Combustion Engines

A PCB assembly that is identifiable as a part of a voltage regulator for internal combustion engine use would generally classify under 8511904000 (voltage regulator parts, NESOI) or 8511902000 if it is specifically for a 6/12/24-volt regulator with cut-out relay. If the PCB serves a broader ignition function not specific to a voltage regulator, 8511906040 or 8511908000 may apply. The classification should follow the part's dedicated function within the parent assembly.

Yes — 8511906020 exists because breaker point sets remain in active trade for the classic and vintage vehicle restoration market, small aircraft with older magneto-based ignition systems, and certain small-engine applications. While modern vehicles use electronic ignition without contact points, the aftermarket for older systems sustains meaningful import volumes, justifying the dedicated classification.
