Import Tips
• Provide acoustic test reports confirming frequency range; U.S
• Customs often requires this for 8518.10.40.00 entry
• Label as 'telecom use only' to avoid reclassification; pitfall is generic 'mic' descriptions triggering audits
• Check for FCC Part 15 compliance if bundled with wireless modules
