Import Tips
• Submit slicing saw blueprints showing arbor integration to demonstrate 'solely or principally' use with wafer equipment
• Check for diamond wire compatibility declarations, as these prove semiconductor-specific application
• Avoid declaring as 'machine parts' generically; specify statistical note reference to prevent reclassification
