Last updated: August 2026 dataTritium (hydrogen-3), a radioactive isotope of hydrogen, along with its compounds, alloys, dispersions, and ceramic products, is classified under a single 10-digit line (2844410000). Tritium's primary commercial applications include self-luminous devices (exit signs, watch dials, gunsights), fusion research, and certain medical and scientific tracer uses. Switzerland and Canada are the leading US suppliers. Imports are subject to NRC licensing as byproduct material, and the low-energy beta emission of tritium — while not an external radiation hazard — requires careful handling documentation for regulatory compliance.

Switzerland hosts major manufacturers of self-luminous devices — particularly precision instruments and watches — that use tritium gas light sources (GTLS) under strict regulatory frameworks. Swiss producers have long-established NRC-approved supply chains for tritium-containing consumer and industrial products, giving them a structural advantage in the US market.
Tritium is regulated as byproduct material under the Atomic Energy Act. Importers must hold an NRC license (or Agreement State equivalent) authorizing possession of tritium, and the foreign manufacturer must be an NRC-approved source. Self-luminous devices containing tritium have specific licensing pathways that differ from bulk tritium gas imports; the intended end use and physical form determine which license category applies.
