Import Tips
• Document the Darlington configuration and high current gain (10,000+) to justify classification under 8541.49.00
• Have technical specifications showing the dual-element structure ready for CBSA review
• Verify whether the phototransistor meets Canadian safety standards for smoke detector applications
