Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If the machine is solely or principally used for semiconductor wafer fabrication
Machines for the manufacture of semiconductor devices or electronic integrated circuits are classified under heading 84.86.
If the machine is numerically controlled and not used for semiconductor applications
Numerically controlled shaping or slotting machines are classified separately under subheading 8461.20.10.
If importing parts for the machine
Parts for machine-tools of heading 84.61 are classified under heading 84.66.
