Import Tips
• Submit blueprints showing grinding precision tolerances and turbine integration for proper HTS verification
• Label equipment clearly as 'semiconductor boule grinder' to prevent classification as general machinery
• Conduct advance ruling requests for complex wafer prep equipment to avoid port delays
