Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If the neptunium-237 oxide is used as a fertile material in reactor applications
Subheading 2844.20 covers fertile elements and isotopes, which may apply if the oxide is intended for fuel or breeding applications.
If the oxide is a pure isotope compound without other elements
Pure radioactive isotope compounds may fall under 2844.10, though Section Note 1(A) requires heading 28.44 to be used exclusively.
