Import Tips
• Verify equipment meets semiconductor industry standards like SEMI specifications for cleanroom compatibility and provide detailed technical datasheets
• Include end-user certificates confirming use in semiconductor mask inspection to avoid reclassification as general optical instruments
• Ensure proper documentation of laser safety classifications if applicable, as customs may scrutinize high-precision optical systems
