Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If grinding machines not semiconductor-specific
Shifts to machine tools if boule processing not exclusively for wafers.
If parts of plain shaft bearings in grinders
If functions primarily as bearing support rather than transmission.
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
• Include boule diameter tolerance specs (±0.1mm typical) in technical data sheets
• Certify materials for ultra-cleanroom compatibility (no lubricants with outgassing)
