Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If extracted and purified thallium salts
Finished thallium chemical compounds move to Chapter 28 inorganic chemicals from raw residues.
If predominantly lead content
Lead ores/ concentrates including residues classified separately in 2617 if not arsenic-focused.
If sold as metallurgical additive
Processed residues used directly in alloying fall under Chapter 38 as metalworking compounds.
