U.S. imports of lithium enriched in lithium-6 and its compounds (HS 284530) totaled $5K in April 2026, traded with 1 country.
Lithium Enriched in Lithium-6 and Its Compounds imports of $5K in April 2026 ran 300% above the year-to-date monthly average of $1K.
Last updated: April 2026 dataLithium enriched in the lithium-6 isotope is a strategically sensitive material used in thermonuclear weapon components and tritium production, placing it among the most tightly export- and import-controlled substances in international trade. A single 10-digit line (2845300000) covers both the enriched metal and its compounds, and NRC licensing is required for import into the United States. South Korea leads supply to the US market, followed by Canada and Germany — a supplier profile that reflects specialized isotope separation capacity rather than conventional lithium mining geography.

Standard lithium metal and compounds are classified elsewhere in Chapter 28 based on chemical form. Lithium enriched in the Li-6 isotope above natural abundance (7.5% Li-6) falls specifically under 2845300000 regardless of its chemical form. Isotopic assay documentation from the producer is essential to support the classification.
Lithium-6 enriched material is controlled under the Nuclear Suppliers Group (NSG) trigger list and is subject to national export licensing in most supplier countries. US importers must coordinate NRC import authorization and should expect origin-country export license requirements that can extend lead times significantly.
