Import Tips

• Verify rebuild certification and maintenance logs to prove compliance with 'used or rebuilt' classification; original manufacturer specs required

• Include detailed condition reports and prior usage history to avoid misclassification as new equipment under 8460.40.40

• Ensure EPA and RoHS compliance for imported refurbished machinery; common pitfall is incomplete serial number tracing
