Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If interchangeable with hand tools
Interchangeable cutting tools for multiple uses fall under Chapter 82 as tools, not dedicated machinery parts.
If for parts of heading 8429 machinery
If principally used with excavators or graders of 8429 instead of tunneling equipment, it shifts to that subheading.
If mounted on mining trucks
Parts for motor vehicles like mining haul trucks are classified in Chapter 87, not stationary tunneling machines.
