Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If multifunctional use across chapters
Fallback to 9033 for parts not solely/principally for Chapter 90 instruments per note 2(c).
If designed for laser measuring instruments
Parts for other optical/measuring apparatus in 9013 take precedence if principal use matches.
If bulk plastic housings without electrical function
Plastic articles of general use excluded by note 1(f) and classified by material.

Import Tips & Compliance
• 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
