Import Tips
• Submit technical specs showing switching speed and capacitance to distinguish from LEDs or photosensitive types
• Use HS code declarations with exact model numbers; watch for undervaluation penalties on high-volume electronics imports
• Ensure RoHS compliance documentation for environmental regulations affecting semiconductor imports
