Import Tips
• Include DIN 69893 or ISO 12164 compliance certificates; critical for Customs verification of machine-specific design
• Declare runout tolerance (≤0.003mm) and max RPM rating to distinguish from general-purpose holders
• Avoid misdeclaration as 'spindle adapter' which could trigger 8466.94 scrutiny for identifiable machine parts
