Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If calcined petroleum coke raw material for electrode production
Unshaped carbon materials classify under Chapter 26 before forming into electrodes.
If general furnace linings not serving as electrodes
Non-conductive carbon shapes for smelters remain general graphite articles.
If pre-assembled into complete electrolytic cell assemblies
Machinery parts for metallurgical equipment take precedence over carbon heading.
