U.S. imports of Other Electrical Ignition & Starting Equipment for Internal Combustion Engines (HS 851180) totaled $12.2M in August 2026, imported from 55 countries.
Importers of Other Electrical Ignition & Starting Equipment for Internal Combustion Engines paid $921K in duties in August 2026, an average duty rate of 9.05% — duty actually collected as a share of the imports that cleared customs, not the published tariff schedule. Other Electrical Ignition & Starting Equipment for Internal Combustion Engines imports of $12.2M in August 2026 ran 29% above the year-to-date monthly average of $9.5M.
Last updated: August 2026 dataVoltage regulators, cut-out relays, and miscellaneous ignition or starting equipment not captured by more specific headings within Chapter 85 fall here, with the US schedule subdividing by voltage rating and function: 6/12/24-volt regulators (8511802000), voltage and volt-current regulators with cut-out relays not elsewhere specified (8511804000), and other ignition equipment (8511806000). The 6/12/24-volt regulator line is particularly relevant for automotive and light commercial vehicle applications, where standardized voltage systems dominate. Section 301 tariffs apply to Chinese-origin goods across all three lines, and the NESOI structure means importers must rule out more specific headings before defaulting to this one.

Voltage regulators specifically designed for use with internal combustion engine charging systems — such as automotive alternator regulators — are classified under 851180. Heading 9032 covers automatic regulating or controlling instruments of a more general-purpose nature. The key distinction is whether the regulator is purpose-built for an ICE electrical system; CBP rulings and the Explanatory Notes to heading 9032 provide guidance on drawing this line for complex electronic regulators.
8511806000 is a catch-all for ICE ignition equipment not covered by the more specific provisions — spark plugs (851110), magnetos (851120), distributors and coils (851130), starters (851140), or generators (851150). Examples might include ignition control modules, crankshaft position sensors used in ignition timing, or proprietary electronic ignition systems that do not fit neatly into the named categories. Importers should exhaust the specific lines before classifying here.
