Import Tips

• Verify engine displacement and power output documentation to confirm classification under vehicle propulsion subheading, avoiding reclassification to stationary engines

• Obtain OEM certification proving the engine is designed solely for Chapter 87 vehicles like trucks, not marine or industrial uses

• Ensure EPA emissions compliance labels are affixed, as U.S. customs requires proof for diesel engines over certain thresholds
