Import Tips & Compliance
• Document CNC control systems and axis configurations to confirm milling function dominance over other operations
• For semiconductor-related imports, provide proof of use in wafer prep equipment to support Chapter 84 statistical note applicability
• Avoid pitfalls by labeling as 'bed type' explicitly; misdescription as 'vertical spindle' can lead to 8459.40 classification errors
