Import Tips
• Include PCB footprint specifications and pinout diagrams to prove incorporation intent for transformer function
• Certify RoHS compliance for electronics imports; non-compliant cores face immediate detention
• Declare exact winding resistance and inductance values to avoid undervaluation claims
