Import Tips
• Submit die photos and fab process descriptions proving semiconductor construction to counter mechanical sensor claims
• Calibrate units pre-import; include NIST-traceable certificates for high-value shipments
• Declare vibration sensitivity ratings to justify transducer status over simple switches
