Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If not one of the specifically listed isotopes
Subheading 2844.43 covers only the 9 named isotopes; other radioactive elements/isotopes classify under 2844.40.
If fissile like plutonium-239 or uranium-235
Fissile isotopes have dedicated subheadings 2844.10-2844.30; non-fissile go to 2844.43 or 2844.40.
If in finished electronic components like wafers
Radioactive materials in processed forms for electronics (discs, wafers) shift from Chapter 28 to heading 3818.
