Products classified under HTS 2844.30.50.50
Thorium Oxide Powder (ThO2)
High-purity thorium dioxide powder used in gas mantles and nuclear fuel research. As a compound of thorium, it qualifies under HTS 2844.30.5050 for 'other' forms in this subheading. Chapter 28 covers such inorganic compounds of radioactive elements like thorium.
Depleted Uranium Hexafluoride (UF6) Cylinders
Cylinders containing UF6 gas with depleted uranium for enrichment plant feed or conversion. HTS 2844.30.5050 covers 'other' compounds of uranium depleted in U235. Excluded from fissile categories per HTS structure.
Thorium Nitrate Crystals
Crystalline thorium(IV) nitrate used in chemical synthesis and nuclear research. As a metal salt compound of thorium, it fits HTS 2844.30.5050 'other' category. Chapter 28 headings 2826-2842 cover such salts.
Depleted Uranium/Titanium Alloy Sheets
DU-0.75Ti alloy sheets for armor-piercing applications and shielding. HTS 2844.30.5050 includes alloys containing uranium depleted in U235 per subheading description. Distinguished from sintered cermets.
Thorium Metal Pellets
High-purity thorium metal pellets for nuclear reactor R&D. Elemental thorium classified as 'other' under HTS 2844.30.5050 per radioactive chemical elements heading. Pure form, not ore.
Depleted Uranium Ceramic Targets
Sintered DU oxide ceramic targets for isotope production. Subheading explicitly includes ceramic products containing uranium depleted in U235. Used in particle accelerators.
Thorium Fluoride (ThF4) Powder
Anhydrous thorium tetrafluoride powder for molten salt reactor fuel. Inorganic compound of thorium under HTS 2844.30.5050 'other'. Chemically defined per Chapter 28 note 1.
Depleted Uranium Dioxide (UO2) Sintered Pellets
Sintered UO2 pellets from depleted uranium for research reactor targets. Ceramic compound form under HTS 2844.30.5050. Distinguished from power reactor fuel assemblies.
Thorium Silicate Mixture
Mixture of thorium compounds with silicates for ceramic applications. Classified as 'mixtures containing thorium compounds' under HTS 2844.30.5050. Specific activity determines heading.
Depleted Uranium Metal Ingots
Solid ingots of depleted uranium (DU), primarily U-238 with less than 0.711% U-235, used in radiation shielding and counterweights. Classified under HTS 2844.30.5050 as 'other' compounds and forms of uranium depleted in U235, excluding ores or separated isotopes. This falls in Chapter 28 for chemically defined inorganic compounds of radioactive elements.
