Import Tips
• Verify equipment qualifies under statistical note (a)(i) for crystal growers; provide technical specs on Czochralski method
• Include FCC certification if electromagnetic components present; common pitfall is misclassifying as general lab apparatus
• Document end-use for semiconductor production to avoid reclassification during customs review
