Import Tips
• Verify semiconductor fabrication origin via manufacturer specs to confirm classification as a transducer, not a complete microphone assembly
• Include detailed datasheets showing piezo-resistive or capacitive sensing elements in import documentation to avoid reclassification
• Watch for anti-dumping duties on Asian-sourced MEMS; ensure proper country-of-origin marking
