Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If for non-electrical pH measurement devices
Mechanical or non-electronic pH sensor parts fall under non-electrical accessories subheading.
If designed for clinical blood gas analyzers
Electrodes principally for medical/dental use classify in 9025 (hydrometers, thermometers, etc.), per Chapter exclusions.
If entered as generic electrical sensors
Without principal use proof for Chapter 90 instruments, they may classify as other electrical machines of 8543.
