Import Tips
• Provide engine model compatibility documentation to prove sole use with marine propulsion engines
• Include material certifications (e.g
• corrosion-resistant alloys) required for marine environments
• Avoid classifying as general engine parts (8409.91.91); specify marine propulsion application
