U.S. imports of alkali & alkaline-earth metals (except sodium) — including lithium, barium & strontium (HS 280519) totaled $1.4M in April 2026, traded with 11 countries.
Importers of Alkali & Alkaline-Earth Metals (Except Sodium) — Including Lithium, Barium & Strontium paid $8K in duties in April 2026 — an effective duty rate of 0.5% on $1.4M in dutiable value, based on actual customs collections rather than the published tariff schedule. Alkali & Alkaline-Earth Metals (Except Sodium) — Including Lithium, Barium & Strontium imports of $1.4M in April 2026 ran 42% below the year-to-date monthly average of $2.5M.
Last updated: April 2026 dataHeading 280519 groups several commercially distinct alkali and alkaline-earth metals — lithium, strontium, barium, and others — that share reactive metallic character but serve very different markets. The US schedule is notably granular: lithium metal enters under 2805199010, barium under 2805192000, strontium under 2805191000, and residual metals under 2805199090, reflecting the separate trade significance of each element. China leads US import supply across this heading, followed by Germany and South Korea, and lithium metal in particular is a strategically watched commodity given its role in battery anodes and chemical synthesis. Importers of lithium metal should assess Section 301 exposure on Chinese-origin goods and monitor critical-minerals policy developments that could affect supply-chain planning.

Within heading 280519, lithium metal is specifically provided for under 2805199010, barium under 2805192000, and strontium under 2805191000. A combined strontium-barium product enters under 2805193050. Metals not specifically enumerated — such as rubidium or cesium — fall under the residual line 2805199090. Correct classification requires knowing the precise elemental identity and, for mixtures, the composition.
Heading 280519 covers only elemental lithium metal in its reduced, unalloyed form. Lithium carbonate, lithium hydroxide, and other lithium salts are classified in Chapter 28 under their respective compound headings, while lithium-ion battery cells and packs fall in Chapter 85. The distinction matters because trade-remedy orders and critical-minerals policies often apply differently across these separate classifications.
