Import Tips & Compliance
• Label as 'for metal or cermets' explicitly; include photos/videos of grinding operation to support classification
• Comply with OSHA safety standards for abrasives; pitfall is undervaluing high-precision models
• Use ISF filing 24+ hours prior; declare correctly to avoid penalties for machine tool imports
