Import Tips
• Document wafer thickness range (50-775μm) and material (Si/Ge) to prove semiconductor classification
• Avoid pitfall of classifying as general lapping/polishing under 8464 if edge-specific functionality emphasized
• Include cleanroom certification (ISO 3-5) in paperwork for fab compatibility
