SITCSection 5
U.S. imports of calcium, strontium, barium, and rare earth metals (SITC 52229) totaled $7.1M in July 2026, traded with 18 countries.
Importers of Calcium, Strontium, Barium, and Rare Earth Metals paid $658K in duties in July 2026 — an effective duty rate of 9.6% on $6.8M in dutiable value, based on actual customs collections rather than the published tariff schedule. Calcium, Strontium, Barium, and Rare Earth Metals imports of $7.1M in July 2026 ran 53% above the year-to-date monthly average of $4.6M.
Last updated: July 2026 dataRare earth metals — including the lanthanide series, scandium, and yttrium — are strategically critical inputs for permanent magnets, phosphors, catalysts, and defense systems, and China's dominant role in global rare earth processing has made supply-chain diversification a policy priority for US manufacturers. Calcium, strontium, and barium metals, while less geopolitically sensitive, serve important roles in metallurgical refining and specialty chemical production. Importers of rare earth metals should monitor export licensing requirements in supplier countries, as several producing nations have implemented export controls or quotas on these materials.

Rare earth elements are essential to permanent magnets in electric motors and wind turbines, phosphors in lighting and displays, and various defense applications. Global processing capacity is heavily concentrated, creating supply-chain vulnerability. This concentration has prompted US government initiatives to develop domestic and allied-nation sources, and importers should track any Section 232 or other trade-remedy developments affecting these materials.
Yes. Several major rare earth producing and processing countries have implemented or signaled export licensing regimes, quotas, or restrictions on certain rare earth metals and compounds. US importers should work with suppliers to obtain required export licenses from the country of origin and maintain contingency sourcing plans, as export restrictions can create sudden supply disruptions.
