Last updated: August 2026 dataDistributors and ignition coils are foundational components of conventional and electronic ignition systems, with the US schedule splitting them into two 10-digit lines: distributors (8511300040) and ignition coils (8511300080). While distributors have largely been displaced by distributorless ignition systems in modern vehicles, they remain widely traded for the classic car restoration and small-engine aftermarket. Ignition coils, by contrast, see robust OEM and aftermarket demand across automotive, motorcycle, and marine segments, and units of Chinese origin are subject to Section 301 tariffs.

Coil-on-plug units that function solely as ignition coils — without an integrated igniter module or other electronic control circuitry that would shift classification — generally remain under 851130 (8511300080). However, integrated ignition modules combining a coil with electronic control functions may be more appropriately classified under a different heading depending on their essential character. A CBP binding ruling is advisable for complex integrated assemblies.
Ignition coils represent substantially higher import volumes than distributors, reflecting the shift to distributorless ignition in modern vehicles. Distributors are primarily imported for the classic and vintage vehicle restoration market, while ignition coils serve both OEM production pipelines and a large aftermarket replacement segment across multiple engine types.
