2844.20.00 - Uranium enriched in U235 and its compounds; plutonium and its compounds; alloys, dispersions (including cermets), ceramic products and mixtures containing uranium enriched in U235, plutonium or compounds of these products

HTS 2844.20.00 specifically classifies uranium that has been enriched in the isotope Uranium-235 (U235), along with its various chemical compounds. This category also encompasses plutonium and its compounds. Furthermore, it includes alloys, dispersions (such as cermets), ceramic products, and mixtures that contain enriched uranium (U235), plutonium, or their respective compounds. The enrichment process increases the concentration of the fissile isotope U235, which is critical for nuclear reactor fuel and other specialized applications.

This classification distinguishes itself from its siblings by its focus on enriched uranium and plutonium. HTS 2844.10 covers natural uranium, which has a low concentration of U235, while HTS 2844.30 deals with depleted uranium (U235 concentration lower than natural uranium) and thorium. The residual sibling category covers other radioactive elements and isotopes not otherwise specified, along with their compounds and mixtures.

Within HTS 2844.20.00, further subdivisions exist to refine the classification. The primary subcategory, 2844.20.00.50, acts as an "Other" provision for items that meet the general description of enriched uranium or plutonium compounds but are not specifically detailed in any further subheadings. This allows for comprehensive coverage of all goods falling under the scope of enriched uranium and plutonium.
