Import Tips
• Verify machine specifications confirm internal cylindrical grinding capability for metal; provide technical datasheets to CBP for classification
• Ensure CE marking or equivalent for safety compliance; common pitfall is misclassification as universal grinder under 8460.29.0135
• Declare value accurately excluding software; obtain rulings for machines with integrated honing functions
