Import Tips
• Verify numerical control features and wafer-specific adaptations in technical specs to confirm classification under 8460.90.4060
• Include detailed end-use documentation proving semiconductor application to avoid reclassification to general machinery
• Ensure vibration isolation and cleanroom compatibility certifications to meet import standards for high-precision tools
