Import Tips
• Provide evidence of semiconductor-specific design (e.g
• contamination-free materials) for correct chapter note application
• Document vacuum levels achieved to distinguish from industrial general-purpose pumps
• Check for export controls on high-vacuum tech under semiconductor equipment regulations
