Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If not exclusively for semiconductor grinding machines
General machinery parts without specific 8464 compatibility fall under Chapter 84 residual provisions.
If integrated with precision measuring for testing
Parts for optical or metrology equipment in semiconductor testing shift to Chapter 90.
If for machines of heading 8465 instead
Heading 8465 covers machine tools for working stone/metals; non-8464 use changes subheading.
