Import Tips
• Verify rebuild certification and maintenance logs to prove 'used or rebuilt' status and avoid new machine classification
• Include detailed spindle speed, table size specs, and CNC control type in commercial invoice for customs valuation
• Ensure machine is free of hazardous materials like old lubricants; common pitfall is missing EPA compliance docs
