Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If when imported as replacement refractory lining parts
Parts of converters are classified separately under 8454.90, not as complete converters.
If designed for drying gases rather than metal refining
Gas drying equipment falls under laboratory/reactor machinery if not metallurgical.
If for non-ferrous chemical reactors
Machines for chemical treatment of non-metals go to 8479, excluding metallurgical converters.
