2844.43.00 - Other radioactive elements and isotopes and compounds; other alloys, dispersions (including cermets), ceramic products and mixtures containing these elements, isotopes or compounds

This HTS category, 2844.43.00, encompasses a broad range of radioactive elements and isotopes, along with their compounds, alloys, dispersions, ceramic products, and mixtures. It specifically includes these radioactive materials when they are not classified under the more specific subheadings of 2844.10, 2844.20, or 2844.30, which deal with natural or artificial radioactive elements and isotopes and their compounds, as well as deuterium compounds.

Distinguishing this category from its siblings, 2844.41.00.00 specifically covers tritium and its related products. Similarly, 2844.42.00.00 addresses a defined list of specific radioactive isotopes such as Actinium-225, Californium-253, and Uranium-232, along with their compounds and mixtures. The sibling category 2844.44.00.00 is reserved exclusively for radioactive residues. Therefore, 2844.43.00 acts as a residual category for other radioactive elements, isotopes, compounds, and their associated materials that do not fit into these more precisely defined sibling classifications.

Within 2844.43.00, further classification is provided by its subcategories. The subheading 2844.43.00.10 is dedicated to elements, isotopes, and compounds exhibiting radioactivity solely from Cobalt-60. The remaining items within this broad category are then further delineated under the general subheading 2844.43.00.50, which covers all other radioactive elements, isotopes, compounds, alloys, dispersions, ceramic products, and mixtures not specifically enumerated in the preceding subcategories. This hierarchical structure ensures precise classification based on the specific radioactive material and its form.
