Import Tips
• Provide engineering drawings showing rolling dies (not cutting tools) and hydraulic displacement mechanism in commercial invoice
• Ensure CE marking or equivalent safety certification for electrical/hydraulic components to meet U.S. import standards
• Declare maximum rolling diameter and material compatibility to avoid reclassification as general forming machinery
