Diversify Your Rare Earth Supply Chain with Latin America’s Untapped Reserves

Rare earth elements (REEs) and strategic minerals form the backbone of modern technology, from electric vehicle batteries and wind turbines to defense systems and consumer electronics. These 17 elements—including neodymium, praseodymium, dysprosium, and terbium—are essential for permanent magnets, lasers, and high-performance alloys. The United States currently imports over 80% of its rare earth supply from China, creating acute supply chain vulnerability. Latin America holds some of the world’s largest undeveloped rare earth deposits, offering a critical alternative for US buyers seeking diversification and security of supply. This page serves procurement managers, mining executives, and government advisors who need to understand the commercial landscape for rare earth and strategic mineral trade between the United States and Latin America.

Rare earths are not actually rare in the Earth’s crust—cerium, for example, is more abundant than copper—but they are difficult to extract and process economically. The term “strategic minerals” extends beyond REEs to include lithium, graphite, cobalt, manganese, and other materials deemed critical for national security and economic competitiveness. The US Department of Energy has identified a growing gap between domestic demand for these materials and domestic production capacity. Latin American countries from Mexico to Argentina hold significant reserves, and several have begun permitting new mining and processing projects. For US buyers, the opportunity lies in securing long-term offtake agreements with Latin American producers who can meet Western environmental, social, and governance (ESG) standards.

Coppermont specializes in connecting US buyers with vetted rare earth and strategic mineral suppliers across Latin America. Whether you need high-purity neodymium oxide for magnet manufacturing or battery-grade lithium carbonate for electric vehicle production, our team can identify qualified sources and manage the cross-border logistics and compliance requirements. The following sections detail the products, producing countries, buyer profiles, certifications, and advisory services that define this dynamic trade sector.

Products and Grades in This Cluster

Rare earth elements are typically categorized into light rare earth elements (LREEs) and heavy rare earth elements (HREEs). LREEs include lanthanum, cerium, praseodymium, neodymium, and samarium, which are more abundant and used in catalysts, glass polishing, and permanent magnets. HREEs such as europium, terbium, dysprosium, yttrium, and erbium are rarer and command higher prices due to their critical roles in phosphors, lasers, and high-temperature superconductors. Strategic minerals outside the REE family include lithium (spodumene and brine), natural flake graphite, cobalt (often as a byproduct of copper or nickel mining), manganese ore, and vanadium for redox flow batteries.

Grades and specifications vary widely by end use. For example, neodymium oxide for sintered NdFeB magnets typically requires 99.5% purity minimum, with strict limits on impurities like iron and calcium. Lithium carbonate for battery applications must meet battery-grade specifications of 99.5% purity with low magnesium and calcium content. Graphite for lithium-ion battery anodes requires 99.95% purity and specific particle size distribution. Buyers must verify that suppliers can consistently meet these specifications through certified laboratory testing and quality assurance programs. Many Latin American producers are investing in downstream processing capabilities to produce higher-value products rather than exporting raw concentrates.

Latin America and Africa Suppliers: Countries and Scale

Latin America hosts some of the most promising rare earth and strategic mineral projects outside China. Brazil has the third-largest rare earth reserves in the world, with significant deposits in the Araxá and Catalão regions of Minas Gerais. The country’s Serra Verde project is one of the few non-Chinese rare earth mines in production, focusing on mixed rare earth carbonate. Chile holds the world’s largest lithium reserves, primarily in the Salar de Atacama, and is expanding production of both lithium hydroxide and lithium carbonate. Argentina’s lithium triangle—spanning Salta, Jujuy, and Catamarca provinces—hosts numerous brine projects that are ramping up to meet global battery demand.

Mexico has substantial fluorspar reserves, a critical mineral for aluminum smelting and uranium processing, as well as growing rare earth exploration activity in Baja California. Peru and Bolivia produce significant volumes of tin and antimony, both classified as strategic minerals. Colombia has emerging cobalt and niobium projects. While Africa is not the primary focus of this advisory, countries like South Africa, Madagascar, and Burundi also produce rare earth concentrates and graphite. The scale of Latin American production is still small relative to China, but capacity is growing rapidly—lithium production in Chile and Argentina alone is projected to double by 2026.

US Buyer Types: Who Buys and What They Need

US buyers of rare earth and strategic minerals fall into several distinct categories. Magnet manufacturers are the largest consumers of neodymium, praseodymium, dysprosium, and terbium, producing NdFeB magnets used in electric vehicle motors, wind turbine generators, and consumer electronics. These buyers require long-term contracts with stable pricing and assured supply, as magnet production lines cannot switch sources easily. Battery manufacturers are the primary consumers of lithium, graphite, cobalt, and manganese, and they demand battery-grade specifications with rigorous traceability from mine to cathode. Defense contractors purchase samarium-cobalt magnets, yttrium for laser systems, and other REEs for guided missiles, radar, and night-vision equipment, with strict ITAR compliance requirements.

Chemical and catalyst companies use lanthanum and cerium for fluid catalytic cracking in petroleum refining and automotive catalytic converters. Glass and ceramics manufacturers consume cerium oxide for polishing and neodymium for coloring. Each buyer type has unique procurement needs: magnet makers often require pre-qualified supplier audits, battery makers need ESG certifications and carbon footprint data, and defense buyers require supply chain security and domestic processing preferences. US buyers increasingly seek suppliers who can demonstrate environmental responsibility, community engagement, and adherence to international labor standards. Coppermont works with buyers to define specifications, conduct supplier due diligence, and negotiate offtake agreements that protect both parties.

Certifications and Compliance for This Cluster

Rare earth and strategic mineral trade between the US and Latin America is subject to a complex web of regulations and certifications. On the US side, the Department of Defense and Department of Energy have established programs to support domestic and allied supply chains, including the Defense Production Act Title III investments and the DOE’s Critical Materials Collaborative. Importers must comply with the Dodd-Frank Act’s conflict mineral reporting requirements for tin, tungsten, tantalum, and gold, though this does not currently extend to REEs. However, due diligence on supply chain ethics is increasingly expected by investors and end customers.

Environmental certifications are critical for Latin American producers. ISO 14001 for environmental management and ISO 45001 for occupational health and safety are baseline requirements for most US buyers. Many buyers also require adherence to the Initiative for Responsible Mining Assurance (IRMA) standard or the Responsible Minerals Initiative (RMI) audit protocols. For lithium, the Lithium-Ion Battery Recycling Standard (UL 1974) is becoming relevant as closed-loop supply chains gain traction. Export controls on rare earths are minimal from Latin America, but US importers must ensure proper tariff classification under the Harmonized Tariff Schedule and may be eligible for duty reductions under USMCA for qualifying Mexican or Canadian content. Legal compliance also includes verifying that suppliers have valid mining concessions, environmental impact assessments, and community consent agreements.
