Import Tips
• Verify ISO taper standards and insert compatibility in documentation to avoid misclassification as general machine parts
• Include manufacturer specs confirming use solely with 8456-8465 machines; common pitfall is lacking end-use certification
• Check for anti-vibration features which may require additional vibration testing declarations for customs
