Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If including spent nuclear fuel residues or irradiated elements
Radioactive residues or spent fuel elements are explicitly under 2844 per chapter note.
If diluted below heavy water threshold and sold as industrial solvent
Lower deuterium content may classify as regular water or hydrogen oxide preparations in 2809.
