More Specific Codes
This product may fall under a more specific subheading:
Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If the controller's primary function is switching rather than current regulation
Switches and other electrical apparatus for switching circuits are classified under 8536, which may apply if the resistor function is secondary.
If the unit includes a static converter or inverter as its main component
Static converters are classified under 8504, which could apply if the controller uses electronic conversion rather than resistive elements.

Import Tips & Compliance
• Ensure the controller's resistor banks are clearly described in your customs documentation as variable resistors for motor starting
• Verify if the product qualifies for duty-free treatment under a free trade agreement by providing a valid certificate of origin
• Be prepared to demonstrate that the controller's principal function is resistive current limiting, not switching, to avoid reclassification
