Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If thyristor-based power controllers
Inverter-duty drives with semiconductor control classify under static converters in 8504.
If only capacitor-based starters
Capacitors for motor starting fall under fixed variable capacitors in 8532, not resistors.
Not sure which classification is right?
The Tariff Assistant works through the GRI rules on your specific product to reach the right HTS code — and can price the duty on it in the same conversation.
Import Tips & Compliance
• Submit Siemens conformance certificates showing resistor motor starting mechanism
• Label with IP rating and enclosure type (NEMA 1/4X) for hazardous location imports
