Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If larger particle size for industrial non-battery uses
Graphite over 1 mm average diameter shifts to block/plate forms under different artificial graphite subheading.
If heavily doped resembling perovskite structures
High dopant concentrations creating defined crystal structures may classify as synthetic metal carbides rather than modified graphite.
If pre-coated onto current collector foil
Electrode assemblies with graphite coating become ceramic capacitors or battery electrodes under Chapter 85.
