U.S. imports of Parts for Electrical Ignition & Starting Equipment and Generators for Internal Combustion Engines (HS 851190) totaled $27.7M in August 2026, imported from 48 countries.
Importers of Parts for Electrical Ignition & Starting Equipment and Generators for Internal Combustion Engines paid $3.6M in duties in August 2026, an average duty rate of 12.82% — duty actually collected as a share of the imports that cleared customs, not the published tariff schedule.
Last updated: August 2026 dataReplacement and service parts for the full range of ICE ignition and starting equipment — from distributor contact (breaker point) sets (8511906020) to voltage regulator components (8511902000, 8511904000) and general engine parts (8511906040, 8511908000) — are distributed across six 10-digit lines under this heading. The breaker point set line reflects continued aftermarket demand for older ignition systems in classic vehicles and small engines. Importers must match each part to the correct parent equipment category, as misclassification between the voltage regulator parts lines and the general ICE parts lines is a common audit finding, particularly for electronic control components.

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.
