Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If paired with matching inner race and balls
Assembled ball bearings classify as complete units, not separate parts.
If mounted in wafer slicing saws for semiconductor production
Parts of semiconductor wafer preparation machines may go to 8479 per statistical notes.
If generic transmission parts not specific to bearings
If not explicitly for ball bearings, could fall under other machinery parts headings.

Import Tips & Compliance
• Provide Rockwell hardness test results (typically 58-65 HRC) and groove geometry specs to confirm ball bearing design
• For semiconductor uses like crystal grinders, note cleanroom compatibility but classify as bearing part unless machine-integrated
• Avoid misdeclaration as 'forgings'; finished machined races must have invoice descriptions specifying 'for ball bearings'
