HS Code 2845.30 – Lithium enriched in lithium-6 and its compounds
HS code 2845.30 is the 6-digit subheading for lithium enriched in lithium-6 and its compounds. It is used for lithium-6 hydroxide, lithium-6 fluoride, lithium-6 metal, lithium-6 deuteride and lithium-6 carbonate.
What HS 2845.30 covers
This code pertains to lithium that has been enriched in the lithium-6 isotope, along with its various compounds. Lithium-6 holds significant strategic importance in nuclear applications, primarily for producing tritium, which is a key component in thermonuclear weapons and a potential fuel for future fusion reactors. It also serves as a neutron absorber in nuclear reactors and in specialized detectors. International trade in lithium-6 is extremely sensitive and heavily regulated due to its dual-use nature and strategic importance for defense and energy research. Importers and exporters are typically national governments or highly controlled entities involved in nuclear programs. Key challenges include stringent non-proliferation controls and the specialized, energy-intensive enrichment processes required for its production.
- Covers
- Lithium-6 hydroxide
- Lithium-6 fluoride
- Lithium-6 metal
- Lithium-6 deuteride
- Lithium-6 carbonate
- Lithium-6 for tritium production.
- Examples
- National nuclear agencies (e.g., US Department of Energy)
- specialized isotope separation facilities.
Codes often confused with 2845.30
Common mistake. This is distinct from natural lithium (2805.40) or other lithium compounds not enriched in lithium-6 (2825.20). The 'enriched in lithium-6' is the crucial differentiator.
Top exporters and importers of HS code 284530, 2025
In 2025, the largest exporter of HS code 284530 in UN Comtrade data was the United States, with 44% of world exports; the largest importer in UN Comtrade data was Germany, with 21% of world imports. Countries that did not report 2025 data are estimated from partner records, which can understate them.

How these figures are built
109 countries reported 2025 trade to UN Comtrade in HS 2022, and their own totals are used. Countries marked * did not, so their figures add up what other countries recorded trading with them, and their exports are valued at buyers' CIF prices. Those estimates miss trade with other non-reporting countries, so they can be low, and a non-reporting country can rank higher than shown or be missing from the list. World totals add both and leave out trade between two non-reporting countries. Figures are in current US dollars; reported imports are mostly valued CIF and exports FOB, and exports include re-exports. The UN Comtrade links show the underlying records; they can also list a few reporters left out here (regional groups and older HS editions).
