Products classified under HTS 2844.20.00.20
Uranium Hexafluoride (UF6)
Uranium hexafluoride is a volatile, chemically defined uranium compound used primarily for uranium enrichment processes in nuclear fuel cycles. It falls under HTS 2844.20.00.20 as a fluoride of uranium enriched in U235 or its compounds, per Chapter 28 notes defining radioactive isotopes and compounds. This white crystalline solid sublimes at low temperatures, enabling gaseous diffusion or centrifugation for isotope separation.
Uranyl Fluoride (UO2F2)
Uranyl fluoride is a yellow crystalline compound derived from uranium hydrolysis of hexafluoride, used in nuclear fuel processing and research. Classified under HTS 2844.20.00.20 as a chemically defined fluoride compound of enriched uranium, aligning with Chapter 28 provisions for radioactive isotopes. It serves as an intermediate in uranium conversion facilities.
Uranium Tetrafluoride (UF4)
Uranium tetrafluoride, or 'green salt,' is a green crystalline powder produced by reduction of UF6, used to fabricate uranium metal or oxide fuel. It is classified in HTS 2844.20.00.20 as a fluoride of fissile uranium enriched in U235, per heading 2844 scope for radioactive compounds. Essential for metal reduction processes in nuclear applications.
Plutonium Trifluoride (PuF3)
Plutonium trifluoride is a chemically defined compound used in nuclear research and pyrochemical reprocessing of spent fuel. It falls under HTS 2844.20.00.20 as a fluoride compound of plutonium, included in heading 2844 per Chapter Note 4 for radioactive elements. Typically handled in gloveboxes due to high radiotoxicity.
Ammonium Uranyl Fluoride ((NH4)2U2O3F8)
Ammonium uranyl fluoride is an intermediate double salt used in uranium purification and fuel fabrication. Classified under HTS 2844.20.00.20 as a uranium fluoride compound, with Chapter Note 6 specifying complex salts in 2842 but overridden by radioactive specificity in 2844. It precipitates from solutions for solid handling.
Uranium Pentafluoride (UF5)
Uranium pentafluoride is an unstable intermediate compound formed during UF6 reactions, studied in nuclear chemistry. It qualifies under HTS 2844.20.00.20 as a chemically defined fluoride of enriched uranium per Chapter 28 definitions. Primarily a research material due to its reactivity.
