Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If primarily for testing semiconductor devices rather than surface finishing
Testing machines for semiconductors are classified in Chapter 90 per statistical notes, not as machine tools.
If valued over $3,025 each
Value threshold determines subheading; higher-value lapping machines shift to other statistical suffixes.
If imported as parts or accessories for lapping machines
Unfinished components or accessories for machine tools are in 8486, not complete machines in 8460.
