Rare Earth Magnets: Why the World Still Relies on China and What Happens Next

Rare earth permanent magnets, primarily neodymium-iron-boron (NdFeB) compositions, are indispensable components in modern technology. They power the traction motors in over 90% of electric vehicles, drive direct-drive wind turbine generators, enable precision-guided weapons systems, and are embedded in everything from MRI machines and industrial robots to smartphone speakers and hard disk drives. The F-35 fighter jet alone contains over 400 kilograms of rare earth materials. Without these magnets, the global energy transition, defense capabilities, and consumer electronics industries would grind to a halt.

China has built an overwhelming dominance over the entire permanent magnet supply chain over the past three decades. The country accounts for approximately 90-94% of global sintered NdFeB magnet production, with output reaching an estimated 240,000 to 300,000 tonnes in recent years. Around 300 Chinese manufacturers produce rare earth permanent magnets. The largest single producer, JL MAG Rare-Earth Co. based in Ganzhou, manufactured roughly 29,000 tonnes of magnet blanks in 2024 alone, a figure comparable to the entire non-Chinese global output combined. JL MAG is expanding capacity from 38,000 tonnes to 60,000 tonnes by 2027. Chinese factories operate at only about 60% utilization, meaning massive spare capacity exists that could flood or starve global markets at will.

The crisis escalated on April 4, 2025, when China's Ministry of Commerce imposed export licensing requirements on seven medium and heavy rare earth elements (samarium, gadolinium, terbium, dysprosium, lutetium, scandium, and yttrium) along with permanent magnet materials. The move came in direct retaliation for the Trump administration's tariff escalations and was framed under national security concerns. Export volumes fell sharply in April and May 2025, forcing some Western automakers to cut production or temporarily shut down factories. European rare earth prices surged to six times their Chinese equivalents.

On October 9, 2025, Beijing announced a far more aggressive second wave of restrictions. These measures introduced China's own version of the Foreign Direct Product Rule (FDPR), requiring foreign entities to obtain Chinese export licenses to re-export any product containing Chinese-origin rare earth materials, even those manufactured and traded entirely outside China. A de minimis threshold of just 0.1% Chinese rare earth content triggered the licensing requirement. Five additional rare earth elements (holmium, erbium, thulium, europium, ytterbium) were added to the controlled list. Export controls were extended to cover the entire supply chain, from mining and smelting technologies to magnet manufacturing and recycling processes.

Following the Xi-Trump summit in late October 2025, Beijing agreed to suspend the October restrictions for one year until November 10, 2026. However, the original April 2025 licensing requirements on the seven initial rare earth elements remain fully in force. Companies exporting these materials still require case-by-case approval from MOFCOM, creating persistent delays and uncertainty. Starting December 1, 2025, entities affiliated with foreign militaries are largely denied export licenses, effectively cutting off direct Chinese rare earth supply to Western defense contractors.

Western nations have scrambled to respond, but the scale gap remains enormous. In the United States, MP Materials began trial production of NdFeB magnets at its Independence facility in Fort Worth, Texas in January 2025, with initial capacity of 1,000 tonnes per year expandable to 3,000 tonnes. The U.S. Department of Defense invested $400 million in MP Materials through a public-private partnership, including 10-year offtake agreements at a price floor of $110 per kilogram, roughly $50 above spot prices. MP Materials has announced plans for a $1.25 billion large-scale facility called 10X in Northlake, Texas, targeting 10,000 tonnes of annual capacity by 2028. Noveon Magnetics in San Marcos, Texas claims production of 2,000 tonnes per year using both conventional and recycled magnet processes. In Europe, Germany's Vacuumschmelze is building a $500 million plant in South Carolina through subsidiary e-VAC Magnetics, targeting 1,500 tonnes annually. Neo Performance Materials opened Europe's first mass-production magnet facility in Estonia in early 2026. France's Carester project targets late-2026 commissioning.

Even with all announced Western projects reaching full capacity, total non-Chinese magnet production would remain in the range of 15,000 to 25,000 tonnes, representing roughly 5-8% of global demand. The development cycle for rare earth processing is lengthy: refineries, separation plants, and magnet production lines require billions in investment and years of permitting. China holds a decisive technological advantage in solvent extraction, heavy rare earth processing, and grain boundary diffusion techniques. Japan, the second-largest producer with 5-10% of global supply, itself depends on China for 67% of its rare earth raw material imports.

The March 2026 Strait of Hormuz crisis has introduced a dangerous new dimension to rare earth supply chain risks. Following U.S. and Israeli strikes on Iran beginning February 28, 2026, Tehran retaliated by effectively closing the Strait of Hormuz to commercial shipping. While this primarily disrupts oil and LNG flows, analysts at Rare Earth Exchanges and other institutions have highlighted that the geopolitical fallout could trigger a Chinese decision to impose a full export ban on permanent magnets as economic retaliation or diplomatic leverage. China receives roughly one-third of its oil via the Strait of Hormuz and has significant economic ties with Iran. If Beijing perceives the military campaign as threatening its strategic interests, rare earth export controls represent its most potent economic countermeasure. Oil prices above $100 per barrel combined with a simultaneous magnet supply cutoff would create cascading disruptions across automotive manufacturing, defense production, wind energy deployment, and industrial automation worldwide.

The suspension of the October 2025 export controls is set to end on November 10, 2026, after which Beijing could reinstate or tighten these restrictions. Industry analysts widely expect China to reintroduce a refined and potentially more restrictive export control regime at that point, incorporating traceability requirements, technology controls, and strategic reciprocity conditions. The current pause should be understood as a temporary window rather than a deregulation. Companies dependent on rare earth magnets face a narrowing timeframe to diversify sourcing, qualify alternative suppliers, and build strategic inventories before the next phase of restrictions takes effect.
