Import Tips
• Obtain OEM part certification from Cummins to prove sole use with 8408 engines
• Include detailed engineering specs in documentation to avoid reclassification as general machinery parts
• Verify RoHS compliance for automotive engines; common pitfall is missing material safety data sheets
