Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If designed for marine propulsion
Marine spark-ignition engines for propelling watercraft are classified separately under 8407.21, regardless of power output.
If over 373.99 kW and for vehicles
Higher power spark-ignition engines intended for motor vehicles fall under vehicle-specific provisions in 8407.34.
If imported as complete mower assembly
When supplied as an integral part of a lawn mower or similar machine, classification shifts to the complete machine under Chapter 84 headings like 8433.

Import Tips & Compliance
• Verify engine displacement and power output documentation to confirm classification under 8407.90.90 and avoid misclassification as marine (8407.21) engines
• Include EPA/CARB emission labels and certificates; non-road engines require compliance with 40 CFR Part 1068
• Declare exact kW rating precisely, as engines over 373.99 kW shift to other subheadings; common pitfall is incomplete technical specs
