Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If classified based on the diamond cutting blade rather than drive
Saw blades and metal cutting tools go to Chapter 82, separating from mechanical drive parts.
If for parts of wire saws identified as metalworking machinery
If not exclusively semiconductor, saw parts may fall under 8466 for tool parts.
If parts of fork-lift style wafer transport machinery
Shifts to 8431.20 if principally for 8427 materials handling equipment.
