Introduction
Following President Trump’s visit to China in May 2026, temporary easing signals emerged in U.S.-China trade talks, but core controls on rare earth exports remain in place. For global procurement professionals in electric vehicles (EV), wind energy, electronics, and defense sectors, this underscores the importance of diversified and resilient supply chains.
Advanced materials companies in China are accelerating investments in closed-loop recycling from electronic waste (e-waste), end-of-life motors, and production scraps—particularly neodymium-iron-boron (NdFeB) magnets, indium, and scandium. This “urban mining” approach offers procurement teams more stable, sustainable sourcing options amid market volatility.
1. Post-Trump Visit: Temporary Relief but Persistent Controls
China implemented export controls on medium and heavy rare earths starting in 2025 in response to trade tensions. This affected supplies of key elements like dysprosium and terbium, critical for high-performance NdFeB magnets.
During the Trump-Xi meetings, rare earths were a key agenda item. While some short-term stabilization and licensing improvements were discussed, full liberalization did not occur. Export licensing systems remain active, leading to ongoing volatility in availability and pricing for international buyers.
Key takeaway for procurement: Expect continued fluctuations. Long-term contracts, diversified sources, and secondary (recycled) materials are essential for risk mitigation.
2. Why Closed-Loop Recycling Matters for Global Supply Chains
Recycling reduces reliance on primary mining, lowers environmental impact, and provides a buffer against export restrictions and price swings. For buyers, recycled rare earth materials can offer more predictable pricing, stronger ESG credentials, and performance comparable to primary materials.
Rare Earth Closed-Loop Supply Chain Process:
- Collection — Electronic waste, end-of-life EV motors, wind turbine generators, and production scraps are collected.
- Dismantling & Demagnetization — Motors and components are disassembled; magnets are demagnetized and separated.
- Preprocessing — Shredding and size reduction to prepare materials for extraction.
- Selective Leaching / Hydrogen Processing — Advanced chemical or hydrogen-based methods extract rare earth elements efficiently.
- Purification & Refining — Rare earth oxides are recovered and refined to high purity.
- Alloying & Advanced Processing — Includes Grain Boundary Diffusion (GBD) technology to optimize magnet performance.
- Re-manufacturing — Recycled materials are turned into new high-performance NdFeB magnets or other components, closing the loop.
This circular process achieves recovery rates exceeding 90% for NdFeB and supports sustainable supply chains.
3. Key Materials and Technologies
NdFeB Permanent Magnets The largest application for rare earths (EV motors, wind turbines, HDDs). China produces vast quantities of manufacturing scraps and end-of-life products, creating rich urban mining opportunities.
- Recovery rates can exceed 90% with advanced processes such as hydrogen processing and selective leaching.
- Chinese recyclers not only recover materials but also integrate cutting-edge techniques like Grain Boundary Diffusion (GBD) technology, which can reduce heavy rare earth (dysprosium and terbium) usage by 40-70% while maintaining or improving coercivity and thermal stability.
- Growing volumes from retiring EV motors and wind turbines will boost future availability.
Indium and Scandium
- Indium: Critical for ITO transparent conductive films in foldable OLED displays and next-generation heterojunction (HJT) solar cells. E-waste recycling offers a valuable secondary source.
- Scandium: Key for high-strength, lightweight aluminum-scandium alloys in aerospace and solid oxide fuel cells (SOFC). Recycling helps address its strategic scarcity.
4. Notable Chinese Corporate Actions
- China Rare Earth Group’s Ganzhou Youli: Launched a technical upgrade project for an annual capacity of 6,600 tons of rare earth oxides from NdFeB waste. It aims to become one of China’s largest single-site recyclers, emphasizing quality, automation, and environmental standards.
- Jinmeng Rare Earth (under Northern Rare Earth): Built an automated production line with 4,000 tons annual capacity (processing ~16,000 tons of scrap), focusing on full-element recovery.
- Huahong Technology (Jiangsu Huahong): Expanded recycling bases in Jiangxi with combined capacity exceeding 12,000 tons of regenerated rare earth oxides annually, targeting production scraps and end-of-life magnetic materials.
These projects primarily focus on NdFeB, while indium and scandium recycling are often integrated into broader e-waste processing.
5. Global Context and Outlook for Procurement
Western companies are investing in recycling to reduce dependency, but China maintains advantages in scale, technology maturity, and cost for secondary rare earths.
Procurement Implications (2026–2030):
- Recycled content could rise to 10-20% in key applications.
- Opportunities for long-term offtake agreements with Chinese recyclers.
- Prioritize traceability, quality certification (ISO, ESG), and hybrid sourcing strategies.
- GBD-enhanced recycled magnets and application-specific materials (ITO for HJT solar, Al-Sc for aerospace) offer strong value.
Conclusion
While the Trump China visit provided short-term dialogue, strategic resource management continues. For international procurement teams, China’s closed-loop recycling investments represent a practical pathway to greater supply security, cost stability, and sustainability.
Engaging with established recyclers can help secure stable volumes of high-quality NdFeB, indium, and scandium materials. In an era of evolving trade dynamics and rising demand, closed-loop systems offer a global opportunity for resilient, responsible sourcing.
