Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If imported as part of a complete polishing machine
The motor would be classified with the machine it powers if presented together.
If the motor is a DC motor with output exceeding 750 W but not exceeding 75 kW
DC motors of this size are classified under heading 85.01 when presented separately.

The Tariff Assistant works through the GRI rules on your specific product to reach the right tariff item — and can price the duty on it in the same conversation.
Import Tips & Compliance
• Classify the motor separately from the polishing machine if imported alone
• Provide evidence of the motor's specific use in semiconductor manufacturing
• Verify if the motor is eligible for duty relief under the Machinery Program
