Import Tips
• Verify frequency response certification (300 Hz-3.4 kHz) and dimensional specs via manufacturer datasheets for customs compliance
• Include telecom end-use declaration; common pitfall is misclassification as general audio mics without size proof
• Ensure RoHS compliance and provide Bills of Materials (BOM) showing MEMS components
