Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If used in mining conveyor systems
Parts for belt conveyors or elevators handling minerals fall under 8431, not dedicated crushing machine parts.
If imported as bulk steel articles without machine context
General steel articles of manganese steel are classified in Chapter 73 unless proven as specific crusher parts.
If parts of grinding machines instead
If designed for grinding rather than crushing mechanisms, shifts to other parts of 8474.90.
