HS code for Lithium-6 enriched compounds: 2845.30
Lithium enriched in lithium-6 and its compounds.
Classification of lithium-6 enriched compounds under HS 2845.30
Lithium enriched in the isotope lithium-6 and its compounds are classified under HS code 2845.30. This classification is unique because it is based on the isotopic composition of the element rather than just its chemical identity. Chapter 28, heading 2845, covers isotopes other than those of heading 28.44 (radioactive isotopes) and their compounds. Lithium-6 is a stable isotope. When lithium is processed to increase the concentration of the lithium-6 isotope beyond its natural abundance, the resulting material and any chemical compounds derived from it are classified here. This is a departure from the standard classification of lithium compounds in headings 2825 or 2836. The specific subheading 2845.30 was created to provide better tracking of this material due to its strategic importance in nuclear technology, specifically for tritium production and neutron absorption applications.

Codes often confused with 2845.30
Common mistake. The most frequent misclassification is placing these compounds under standard lithium codes, such as 2805.19 for lithium metal, 2825.20 for lithium hydroxide, or 2836.91 for lithium carbonate. While those codes are correct for lithium with a natural isotopic abundance, any enrichment in the lithium-6 isotope mandates classification under 2845.30. Another potential error is confusing lithium-6 with radioactive materials in heading 2844. Since lithium-6 itself is stable and not radioactive, it must be classified in 2845. Importers must ensure that the isotopic assay is clearly documented to justify the use of this specific and highly regulated HS code.
Top exporters and importers of HS 284530 (the code used for lithium-6 enriched compounds), 2025
In 2025, the largest exporter of HS 284530 (the code used for lithium-6 enriched compounds) 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).
