U.S. and Allies Struggle to Build Rare Earth Supply Chain

The United States and its allies are attempting to establish a domestic supply chain for rare earth magnets to decrease reliance on China, which dominates global processing. The effort faces significant obstacles due to shortages of dysprosium and terbium, heavy rare earth elements essential for wind turbines, defense technology, and electric vehicle engines.

MP Materials is leading the American initiative with billions in government funding, though its California mine contains only trace amounts of these heavy elements. To mitigate this, the company entered a $500 million agreement with Apple Inc. for recycled materials and continues to seek additional feedstock providers.

Other international firms are securing alternative sources. Germany's Vacuumschmelze opened a plant in South Carolina and secured supply deals in Brazil and Canada. Australia's Lynas Rare Earths utilizes operations in Malaysia to produce heavy rare earths, while Iluka Resources is building a refinery in Western Australia expected to be operational by 2027.

Despite these strategic investments, analysts project the West will still rely on China for 91% of its heavy rare earths by 2030. High processing costs and environmental bottlenecks continue to hamper the transition toward a diversified supply chain.
