Import Tips
• Verify engine power output certification exceeds 18.65 kW with manufacturer specs and test reports for customs compliance
• Include documentation proving intended use for Chapter 87 vehicles to avoid reclassification as general purpose engines
• Label cylinder capacity clearly (250-1000cc) and ensure no marine or aircraft adaptations to prevent duty shifts
