Import Tips
• Include process diagrams demonstrating float zone RF heating for semiconductor materials in entry documentation
• Confirm boule diameter specs match industry standards (150-450mm) to validate semiconductor-specific classification
• Watch for misclassification as vacuum furnaces; emphasize semiconductor boule end-use
