Import Tips
• Provide OEM model cross-reference to confirm linkage to 9030.39; generic probes risk 9033 classification
• Ensure calibration certificates are included; EU-origin probes may qualify for preferential tariffs
• Avoid misdeclaration as 'cable assemblies'—specify 'instrument-specific probe' to prevent 8544 shifts
