What Are Rare Earths and Why Are They Critical for Automakers?
Rare earth elements represent a group of 17 metallic elements on the periodic table that, despite their name, aren't particularly rare in the Earth's crust. What makes them "rare" is their dispersed distribution, which makes economically viable deposits uncommon. These elements—including neodymium, dysprosium, praseodymium, and terbium—possess unique magnetic, luminescent, and electrochemical properties that make them irreplaceable in modern automotive manufacturing.
For automakers, rare earth elements are critical components in the production of high-performance permanent magnets, which power everything from electric motors to sensors. In electric vehicles (EVs), these magnets are essential for the traction motors that convert electrical energy into mechanical power. A typical EV can contain up to 3kg of rare earth materials, primarily in its motor assembly.
According to data from Mining Weekly (June 2025), neodymium-iron-boron (NdFeB) magnets—containing approximately 30% rare earth elements—deliver the highest energy density of any commercial magnet, making them ideal for the compact, lightweight motors needed in modern vehicles.
Understanding Rare Earth Elements and Their Applications
In conventional vehicles, rare earth elements appear in catalytic converters, where cerium and lanthanum help reduce harmful emissions. These elements also feature in numerous small motors throughout vehicles—controlling everything from power windows to mirror adjustments.
The transition to electric mobility has dramatically increased automotive demand for rare earths. A single EV can use significantly more rare earth materials than a conventional vehicle, primarily in permanent magnet synchronous motors (PMSMs) that offer superior power density and efficiency compared to alternatives.
As one industry analyst noted, "The EV revolution is, in many ways, contingent upon critical minerals energy transition. Without these materials, the high-performance motors that consumers expect become difficult or impossible to produce at scale."
Hybrid vehicles present a middle ground, requiring rare earth elements for both their electric components and traditional systems. Their dual powertrain design can sometimes mean they actually require more rare earth content than pure electric vehicles.
China's Dominance in the Rare Earth Supply Chain
China's control over global rare earth production is staggering. Mining Weekly (June 2025) reports that China produces approximately 90% of the world's rare earth elements. Even more concerning for global supply chains, Andreas Kroll of Noble Elements states that "China controls practically 99.8% of global production of heavy rare earths"—the subset of rare earth elements that are particularly crucial for high-performance applications.
This dominance didn't happen by accident. Beginning in the 1980s, China made strategic investments in rare earth mining, processing, and manufacturing capabilities. By the early 2000s, China had effectively cornered the market, driving most Western producers out of business through competitive pricing.
What makes China's position especially powerful isn't just mining capacity—it's the processing infrastructure. Refining rare earth ore into usable materials involves complex, environmentally challenging processes. China has built this capacity over decades, creating a bottleneck that even countries with their own rare earth mines often can't circumvent.
The Mountain Pass mine in California, for example, ships much of its concentrated rare earth ore to China for processing—a stark illustration of China's control beyond mere extraction. This processing dominance means that even diversified mining operations often lead back to Chinese refineries, creating what industry experts call a "permanent dependency" in the supply chain.
What Export Controls Has China Implemented?
In April 2025, China stunned global markets by announcing comprehensive export restrictions on rare earth materials and related products, significantly tightening a resource chokepoint for global industries. These controls represent a dramatic escalation in ongoing trade tensions and have particularly severe implications for the automotive sector.
Timeline of China's Rare Earth Export Restrictions
The April 2025 announcement marked a watershed moment in global trade relations. According to Mining Weekly (June 2025), China suspended exports of "a wide range of rare earths and related magnets" with little warning, affecting both raw materials and finished components.
The export controls implemented a complex licensing system requiring extensive documentation and approvals from multiple Chinese regulatory bodies. Data from the European Association of Automotive Suppliers (CLEPA) indicates that merely 25% of export license requests have been approved since the restrictions began.
Chinese authorities have rejected numerous applications on what CLEPA describes as "highly procedural grounds," creating significant uncertainty for global manufacturers. The licensing process, initially presented as a formality, has become a de facto export ban for many products.
The restrictions cover both raw rare earth materials and value-added products like magnets, affecting multiple points in the supply chain. This comprehensive approach effectively prevents manufacturers from circumventing restrictions by importing finished components instead of raw materials.
Strategic Motivations Behind the Export Curbs
The timing of China's export controls aligns directly with escalating trade tensions with the United States, particularly following tariff increases implemented by the Trump administration. Many analysts view the rare earth restrictions as strategic leverage in broader trade negotiations.
"China is demonstrating its ability to disrupt global supply chains at will," noted one industry expert. "This gives them significant bargaining power in trade talks, particularly with sectors that cannot quickly source alternatives."
Beyond immediate trade concerns, the export curbs also support China's domestic manufacturing ambitions. By restricting raw material exports while encouraging domestic production of high-value components, China aims to move its rare earth industry up the value chain—transitioning from being primarily a resource supplier to a manufacturer of finished high-tech products.
The restrictions also serve national security interests by limiting foreign access to materials critical for defense applications. Many rare earth elements have dual civilian and military uses, making them strategically important beyond their commercial value.
EU Commissioner Stephane Sejourne directly addressed this strategic dependency, stating, "We must reduce dependencies on China" (Mining Weekly, June 2025). This acknowledgment from high-level officials underscores the geopolitical dimensions of the rare earth supply chain.
How Are Global Automakers Being Affected?
The impact of China's rare earth export restrictions has cascaded through automotive supply chains, creating production disruptions across multiple continents. While some manufacturers had anticipated potential supply issues and built inventory buffers, others have faced immediate operational challenges.
Current Production Disruptions
According to CLEPA, several European auto parts manufacturers have been forced to suspend production lines due to the inability to secure necessary rare earth materials (Mining Weekly, June 2025). These shutdowns have primarily affected component suppliers rather than final assembly plants, though the effects are beginning to ripple upward through the supply chain.
The limited approval rate for export licenses—just 25% according to CLEPA data—has created a severe bottleneck. Companies report that even when licenses are granted, shipments face extended delays at Chinese ports, compounding supply uncertainties.
ZVEI CEO Wolfgang Weber highlighted the urgency of the situation, warning that "some companies only have weeks or months of supplies left" (Mining Weekly, June 2025). This timeline suggests that more severe production disruptions may emerge as existing inventories are depleted.
Tier-one suppliers producing electric motors, sensors, and emission control systems have been particularly affected. These companies often operate with lean inventory systems designed for just-in-time delivery, making them especially vulnerable to supply disruptions.
Automaker Responses and Mitigation Strategies
Major automakers have implemented various strategies to manage the supply disruptions, with mixed results.
Mercedes-Benz is exploring "buffer" strategies, including potential stockpiling of critical components. As Joerg Burzer, the company's production chief, explained, "We're working on securing alternative supply routes and building strategic minerals reserve where possible" (Mining Weekly, June 2025).
Ford's Chief Financial Officer Sherry House acknowledged the ongoing challenges during a recent earnings call: "We're managing [supply chain stress], but it continues to be an issue" (Mining Weekly, June 2025). The company has established a dedicated supply chain resilience team focusing specifically on rare earth materials and components.
BMW has reported disruptions in its supplier network but maintains that its plants remain operational. The company attributes part of its resilience to its strategic decision to develop magnet-free electric motors, which reduce dependency on certain rare earth elements. However, BMW still requires rare earths for numerous smaller components throughout its vehicles.
Swedish auto safety supplier Autoliv has established a task force to manage potential disruptions, working directly with both Chinese suppliers and government officials to secure necessary export approvals. This direct engagement approach has helped maintain some continuity of supply.
Smaller manufacturers with less negotiating leverage have been disproportionately affected, with some reporting complete inability to secure export licenses despite multiple applications. This disparity threatens to create competitive imbalances within the industry.
What Are the Long-Term Industry Implications?
The current disruptions expose fundamental vulnerabilities in global automotive supply chains that extend beyond immediate production challenges. The industry faces a strategic inflection point that could reshape development priorities, supply chain structures, and competitive dynamics.
Supply Chain Vulnerability Concerns
The rare earth crisis bears striking similarities to the semiconductor shortages that devastated automotive production during the COVID-19 pandemic. Both situations highlight the industry's exposure to concentrated supply sources and limited ability to rapidly develop alternatives.
Automotive executives increasingly view the rare earth situation as a "strategic wake-up call" similar to the chip shortage, which cost the industry an estimated $210 billion in lost revenue. The rare earth disruption could potentially trigger comparable financial impacts if prolonged.
The current situation reveals a critical weak point in electrification strategies. As one industry analyst observed, "Automakers have committed billions to EV transitions without securing the material inputs those vehicles require. This fundamental disconnect creates systemic risk across the industry."
Component suppliers face particular vulnerability, as they typically operate with thinner margins and less financial capacity to weather extended disruptions. Several industry analysts predict potential consolidation among tier-two and tier-three suppliers as smaller companies struggle to maintain operations amid supply uncertainties.
Acceleration of Alternative Technologies
BMW's development of magnet-free electric motors now appears prescient in light of current disruptions. The company's fifth-generation eDrive technology uses wound-field synchronous motors that eliminate the need for rare earth permanent magnets in main drive units. However, as BMW acknowledges, rare earths remain necessary for numerous smaller components throughout their vehicles.
Research into reduced-rare-earth motors has accelerated across the industry. Companies including Tesla, Renault, and Toyota have active development programs focusing on switched reluctance motors, asynchronous motors, and ferrite-based alternatives to rare earth magnets.
Andreas Kroll of Noble Elements highlights the challenges in this transition, noting that lab-scale production of heavy rare earths outside China is "minimal" (Mining Weekly, June 2025). This assessment suggests that technological alternatives, rather than alternative supply sources, may offer the most viable path to reduced dependency.
The cost equation remains challenging for alternative technologies. Most rare earth substitutes currently involve performance trade-offs, higher manufacturing costs, or both. As one engineering executive noted, "We can design around rare earths, but not without consequences for vehicle performance, cost, or both."
How Are Governments Responding to the Crisis?
The rare earth supply disruption has elevated from a commercial concern to a matter of national security and economic policy. Governments worldwide are implementing both diplomatic initiatives and domestic investment programs to address the immediate crisis and build long-term resilience.
EU Response and Diversification Efforts
The European Union has taken particularly aggressive action, recognizing its automobile industry's vulnerability to supply disruptions. EU trade commissioners have engaged in direct negotiations with Chinese counterparts, seeking both immediate relief for affected companies and longer-term supply agreements.
According to Mining Weekly (June 2025), the EU has identified 13 new projects specifically designed to increase critical mineral supplies, including rare earth elements. These initiatives range from mining operations within EU member states to establishing a CRM facility in Europe that can refine materials sourced from third countries.
EU Commissioner Stephane Sejourne has explicitly framed these efforts as strategic independence initiatives, stating, "We must reduce dependencies on China" (Mining Weekly, June 2025). This represents a significant shift from previous EU policy, which emphasized global trade integration over supply chain sovereignty.
The EU's Critical Raw Materials Act, adopted in 2023, has become the framework for these diversification efforts. The legislation established benchmarks requiring that by 2030, at least 10% of the EU's annual rare earth consumption must be extracted within the EU, with processing capacity for 40% of annual consumption.
U.S. Policy Response
The United States has approached the rare earth crisis through both diplomatic and domestic channels. The Trump administration has incorporated rare earth access into broader trade negotiations with China, seeking specific commitments regarding export availability.
Scheduled talks between Presidents Trump and Xi are expected to address rare earth supplies directly, according to State Department sources. These negotiations occur against the backdrop of tensions in implementing the previously agreed tariff reduction agreement.
On the domestic front, the U.S. has expanded funding for rare earth processing capacity, building on initiatives established under the Inflation Reduction Act and the CHIPS and Science Act. Recent developments in the critical minerals order have further prioritized domestic production capabilities.
The Department of Defense has also intensified its involvement, designating certain rare earth materials as strategically critical and establishing stockpile requirements. This military dimension adds complexity to negotiations, as both countries recognize the dual-use nature of these materials.
What Are the Potential Solutions for Automakers?
Facing a complex supply challenge with no quick resolution, automotive companies must develop both immediate mitigation strategies and long-term structural solutions to maintain production continuity and build resilience.
Short-Term Mitigation Strategies
Inventory management has emerged as the first line of defense, with companies reassessing optimal stock levels for critical components. This represents a significant shift from the industry's decades-long movement toward just-in-time manufacturing.
Autoliv's approach of establishing dedicated task forces provides a model other companies are following. These cross-functional teams combine procurement, engineering, and government relations specialists to address supply challenges holistically rather than treating them as purely purchasing issues.
Securing alternative supply sources remains challenging but not impossible. Some manufacturers have successfully redirected procurement to the limited non-Chinese producers, particularly for lighter rare earth elements. However, as Andreas Kroll of Noble Elements notes, China's 99.8% control of heavy rare earth production makes alternatives for these materials virtually nonexistent.
Component redesign offers another potential avenue, with engineering teams evaluating whether certain parts can be modified to use more readily available materials. This approach requires careful balance between supply security and maintaining product performance.
Long-Term Resilience Building
Investment in rare earth mining and processing outside China has accelerated dramatically. According to industry data, capital flowing into rare earth projects has tripled since 2022, with major developments underway in Australia, Canada, and the United States.
The development of technologies requiring fewer or no rare earth elements represents perhaps the most sustainable long-term solution. BMW's commitment to magnet-free motors exemplifies this approach, though the company acknowledges that complete elimination of rare earth dependence remains unfeasible with current technology.
Recycling and recovery of rare earths from end-of-life products offers another promising avenue. While currently operating at limited scale, recycling technologies have demonstrated the ability to recover up to 90% of rare earth content from magnets and other components. Several European automakers have launched pilot programs for closed-loop rare earth recycling, potentially creating circular supply chains less vulnerable to geopolitical disruptions.
Vertical integration strategies, with automakers taking direct stakes in mining and processing operations, have gained traction. This approach, while capital-intensive, provides greater supply security and visibility throughout the value chain. Furthermore, the ongoing mining industry evolution is creating new opportunities for strategic partnerships that can help address these supply challenges.
What Is the Outlook for Rare Earth Supply Security?
The path toward rare earth supply security involves complex interactions between geopolitics, technology development, market forces, and regulatory frameworks. Industry stakeholders must navigate this multidimensional landscape while maintaining operational continuity.
Industry Expert Assessments
Andreas Kroll of Noble Elements offers perhaps the most sobering assessment of the situation, stating there is "no solution for the next three years except to come to an agreement with China" (Mining Weekly, June 2025). This timeline reflects the reality that developing alternative mining and processing infrastructure requires substantial lead time.
The challenges in developing alternative supply chains for heavy rare earths appear particularly daunting. Even with accelerated investment, industry experts estimate that non-Chinese sources could supply at most 5-10% of global heavy rare earth demand within the next five years.
Laboratory-scale production outside China remains "minimal," according to Kroll (Mining Weekly, June 2025). This technical limitation means that even with unlimited funding, scaling alternative supply chains faces fundamental capacity constraints that cannot be quickly overcome.
Industry analysts increasingly differentiate between light and heavy rare earths in their forecasts. Light rare earths, including neodymium and praseodymium, have more viable alternative sources, while heavy rare earths like dysprosium and terbium face more severe supply constraints.
Future Supply-Demand Dynamics
Growing demand from the EV transition and renewable energy sectors creates additional pressure on rare earth markets. Industry forecasts project that automotive demand for rare earth elements could triple by 2030 if current technology trends continue.
Emerging mining projects offer some promise for supply diversification. Significant developments in Australia's Mount Weld, Canada's Strange Lake, and Greenland's Kvanefjeld projects could collectively provide up to 25% of global rare earth supply by 2030, according to industry estimates.
However, these projects face substantial challenges
