Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If radioactive isotopes other than U/Th
Compounds of elements beyond U/Th (e.g., radium) fall under 2844.40 per note 4(a).
If nitrate salts of non-radioactive metals
Non-radioactive nitrates like yttrium nitrate classify under 2827.39; radioactivity determines Chapter 28 heading 2844.
If calcium double salt derivatives
Certain metal cyanamide derivatives like calcium cyanamide exclude to Chapter 31 per Chapter 28 note 2.
