Import Tips
• Label as 'polishing only' to distinguish from cutting wheels and prevent misclassification under cutting tool codes
• Provide grinding RPM specifications in invoices to confirm non-cutting use per HTS description
• Check for anti-dumping duties on Chinese-origin diamond abrasives; origin certificates are essential
