Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If containing >70% petroleum bitumen
High bitumen content shifts classification to petroleum coke mixtures rather than carbonaceous pastes for electrodes.
If when formed into finished non-electrical articles
Pre-formed carbon shapes for non-electrode uses like brushes fall under articles of carbon fibers or graphite.
