MEMS Telecom Microphone Module from Japan
A miniature MEMS microphone designed for telecommunication devices, with a frequency range of 300 Hz to 3.4 kHz, diameter under 10 mm, and height not exceeding 3 mm. It converts voice signals into digital data for mobile phones and VoIP systems. This falls under HTS 8518.10.40.00 due to its precise size and frequency specs for telecom applications.

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
