More Specific Codes
This product may fall under a more specific subheading:
Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If the dispersion is in the form of a cermet
Subheading 2844.30 specifically includes cermets containing radioactive isotopes, which may be more precise than the residual 2844.43.00.
If the promethium-147 is in pure isotopic form without a ceramic matrix
Pure radioactive isotopes are classified under 2844.10 per Section Note 1(A), which takes precedence over other headings.
