Import Tips & Compliance
• Verify the device records data continuously and provide sensor calibration certificates to confirm classification as a recording thermograph
• Include technical specifications showing temperature recording functionality to avoid misclassification as non-recording thermometers (9033)
• Ensure FDA or NIST traceability documentation if used in food/pharma, as customs may scrutinize end-use applications
