Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If specifically for semiconductor crystal grinders instead of saws
Different statistical suffixes distinguish parts by specific semiconductor processing step.
If for use in general precision grinding machines
Parts of metal-working machine tools classify in heading 8466, not bearing parts.
If imported as complete thrust cylindrical roller bearing assembly
Complete bearing assemblies (not parts) have separate provisions from replacement parts.
