Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If the potentiometer uses a conductive plastic or hybrid element
Variable resistors of other materials are classified under a separate subheading.
If the potentiometer is a fixed resistor with a power rating below 20 W
Fixed resistors under 20 W are classified under a different subheading.
If imported as a replacement part, such as a shaft or wiper assembly
Parts of resistors are classified under the parts subheading.
