Import Tips
• Include engineering drawings showing integration with wafer slicing saw spindle assemblies
• Document bore diameter tolerances specific to semiconductor saw blade shafts (typically <50mm)
• Avoid misclassification by providing evidence of exclusion from automotive/general industrial use
