Import Tips

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
