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 imported together with the crystal grower as a complete machine
Machines for the manufacture of semiconductor boules are classified in heading 84.86, and the dividing head may be considered a part of that machine.
If the item is a general-purpose part rather than a special attachment
Other parts for machines of headings 84.56 to 84.65 may fall under this heading if not specifically a dividing head.
