Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If low-grade with >50% other minerals
Low-purity graphite ores classify under Chapter 26 as mineral substances.
If expanded into exfoliated form
Expanded graphite products treated as carbides of silicon or chemical derivatives.
If coated for foundry use
Pickling preparations or coated graphite shift to Chapter 38.
