Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If as parts of unlisted semiconductor machines
Equipment not fitting 8456-8465 headings defaults to Chapter 84 unspecified machines.
If for inline wafer metrology lapper fixtures
Measuring/profile projecting instruments for wafers classify in Chapter 90.
If tool holders rather than machine frames
Specific tool-holding functions shift to dedicated tool holder subheading.
