Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If imported as part of a complete grinding machine
The drive unit would be classified with the machine it powers if presented together.
If the drive unit is an AC motor exceeding 750 W but not exceeding 75 kW
AC 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
• Ensure the drive unit is declared separately from the grinder if imported alone
• Provide technical data showing the unit's role in wafer thinning
• Check if the unit qualifies for duty-free entry under a trade agreement
