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
