Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If optimized specifically for aluminum reduction cells
Cathodes meeting prebaked aluminum cell technical specs have a dedicated subheading separate from general electrolytic electrodes.
If for industrial furnace linings not involving electrolysis
Carbon blocks used primarily for thermal rather than electrical conduction in furnaces classify under non-electrical carbon articles.
If sold as petroleum coke precursor material
Unformed petroleum coke for cathode production falls under petroleum products before graphitization and electrode forming.
