Import Tips
• Provide process flow diagrams showing float zone RF heating to confirm classification under semiconductor statistical notes
• Ensure documentation distinguishes from general melting furnaces to prevent reclassification
• Watch for partial assemblies; complete systems may shift to 8486 if deemed semiconductor fab machines
