More Specific Codes
This product may fall under a more specific subheading:
Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If the machine is solely or principally used for manufacturing semiconductor devices
Heading 84.86 specifically covers machines for the manufacture of semiconductor devices, which may be more appropriate for crystal pullers.
If the machine operates primarily by a temperature change process
Heading 84.19 covers machinery for the treatment of materials by a change of temperature, which may apply if the puller's primary function is thermal.
