U.S. exports of Ignition Magnetos, Magneto-Dynamos & Magnetic Flywheels for Internal Combustion Engines (HS 851120) totaled $2.2M in August 2026.
Importers of Ignition Magnetos, Magneto-Dynamos & Magnetic Flywheels for Internal Combustion Engines paid $145K in duties in August 2026, an average duty rate of 6.60% — duty actually collected as a share of the imports that cleared customs, not the published tariff schedule.
Last updated: August 2026 dataMagnetos and magnetic flywheels serve as self-contained ignition power sources in applications where a battery-based system is impractical — notably small aircraft piston engines, racing engines, and certain outdoor power equipment. All three device types (ignition magnetos, magneto-dynamos, and magnetic flywheels) consolidate into a single 10-digit line (8511200000), so importers do not need to distinguish among them for tariff purposes. The aviation segment warrants particular attention to FAA Parts Manufacturer Approval (PMA) or Technical Standard Order (TSO) documentation, which customs brokers should coordinate with compliance teams before entry.

Yes. Magnetos intended for use in certificated aircraft must comply with FAA airworthiness requirements, including PMA or TSO authorization. While CBP handles the customs entry, the FAA governs airworthiness approval, and importers should ensure the product's certification status is confirmed before the goods enter the US aviation supply chain.
For HTS purposes, there is no classification difference — ignition magnetos, magneto-dynamos, and magnetic flywheels all fall under 8511200000. The distinction matters commercially (a magnetic flywheel integrates the rotor and ignition trigger into a single spinning mass, while a traditional magneto is a separate assembly), but both are treated identically at the tariff line level.
