Import Tips
• Verify calibration certificates and ensure the instrument meets NIST traceability standards for U.S. customs compliance
• Include detailed technical specs in documentation to confirm process control function and avoid misclassification as general sensors
• Check for ITAR restrictions if the controller incorporates advanced software for industrial applications
