Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If assembled thermocouples
Complete temperature sensors classify in Chapter 90 instruments.
If alumel/chromel alloys
Thermocouple alloys (Ni-Al) exceed purity limits, become alloyed.
If insulated sensor wire
Insulated thermocouple wire may classify as Chapter 85 electrical conductors.
