Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If tritium or its compounds
Tritium (H-3) falls under specific subheading 2844.10 for tritium and compounds, not 'other' elements.
If actinium-225 or polonium-210
These specific isotopes have dedicated subheadings in 2844.20, excluding them from the 'other' category.
If prepared for medical radiopharmaceutical use
Isotopes in preparations for medical/surgical use shift to heading 2845, not Chapter 28 raw elements.
