Tritium, Its Compounds, Alloys, Dispersions & Ceramic Products

Tritium — a radioactive hydrogen isotope with a 12.3-year half-life — is a specialized material used in self-luminous devices, neutron generators, and fusion research, and its import is subject to NRC licensing as a byproduct material under the Atomic Energy Act. The entire heading resolves to a single 10-digit line (2844410000), reflecting the narrow commercial universe of tritium trade. Switzerland, Canada, and France are the leading foreign sources, consistent with the concentration of tritium production and handling capability among a limited number of licensed nuclear facilities worldwide. Importers should be aware that tritium-containing products may also trigger additional export-control review in the country of origin.
