Import Tips
• Provide NIST-traceable calibration data to demonstrate sub-micron precision capability required for classification
• Avoid common pitfall of incomplete CNC documentation; include full control system specifications
• Consider bonding warehouses for semiconductor equipment imports to manage cash flow during classification reviews
