Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If primarily a thermostat without integral clock movement
Automatic regulating thermostats without timekeeping function classify under Chapter 90 as measuring instruments, not Chapter 91 time switches.
If for industrial control panels with timing function
Programmable logic controllers and similar boards for factory automation fall under heading 8537, not as standalone time switches of Chapter 91.
If valued $5 or less per unit
Same product but lower unit value shifts to the subheading for time switches valued not over $5.
