In the past 15 years, China has transformed from a rising miner and material processor to the undisputed gatekeeper of critical minerals. Today, it not only refines over 90 % of global rare-earth oxides but also processes 85 to 90 % of the world’s “mine-to-metal” REE capacity. This article unpacks how China’s export-control playbook has evolved, what it means for global supply chains, and why semiconductor makers now have skin in the game.
Origin: How it all started ?
2010 & 2012: China first required export licenses for key rare-earth elements (REEs), citing environmental and resource-security concerns. The measures back then were enforced to control the volume of REE and light rare-earth elements(LREE) that left the country.
Fast forward to April 2025, amid rising U.S. tariffs and tech blacklists, Beijing formally added neodymium-iron-boron (NdFeB) permanent magnets to its restricted list. These magnets power EV motors , wind turbines crucial for the EV and other applications. Given China holds 90 % market share, it aims to control the supply chain using this to their advantage.
The Battery-Materials Clampdown
On July 15, 2025, China expanded its export-control catalogue to include battery-cathode preparation and lithium-processing technologies. These restrictions are different from the once imposed in 2012 which merely controlled the quantum of material exported and not the technical know-how or process technology
- LFP & LMFP cathode formulations
- Spodumene derived lithium carbonate extraction and refining
- Direct-lithium-extraction (DLE) processes
These restricts acts a hurdle especially for upstream players. China accounts for nearly 75 % of the global battery patents, giving them a massive edge. In recent years the number of patents related to emerges chemistries like LMFP , Na-ion , High Ni NMC have increased. This shows they are not only innovating but driving market shift. The penetration of LFP in last 2 years is proof of this long-term strategy.
China’s Stance
China’s Commerce and Science Ministries frame these controls as a protecting their strategic assets and promoting in-house innovation. Being a market leader in battery technology China is selective about what “know how” it wants to share globally.
Global Backlash & Diversification
Western automakers and tech firms have voiced concerns over potential gigafactory delays and cost spikes. In response:
- United States: Through the CHIPS & Science Act, the DoD holds a 15 % stake in MP Materials, which is building a magnet plant in Oklahoma, and has earmarked $2 billion for domestic lithium hubs.
- European Union : The Critical Raw Materials Act mandates 10 % domestic extraction by 2030 along with additional targets for refining and recycling. CATL’s €7 billion JV in Thuringia presses on, but now under tighter licensing.
Impact on Ongoing JVs
China’s top-three battery makers have collectively announced 15+ gigafactories abroad (Europe, U.S., Southeast Asia). Under the new regime, the projects could face the following hurdles
- Export-license delays (45 + days under China’s Export Control Law) may push back commissioning.
- Rising capex as JVs must internally develop or license alternate processes. This means more investments in R&D
Who’s in the Crosshairs : Upstream Players
The curbs will mainly affect the upstream processes that deal with material processing & synthesis.
- CAM manufacturers (LFP, NMC, LMFP blends)
- Lithium concentrators & refiners (spodumene to carbonate)
- Specialty-chemicals suppliers (binders, solvents)
Downstream players (cell manufacturing and battery-pack integration)currently won’t be affected directly. However, the bottlenecks in the upstream processes might raise concerns and lead to pivot in business strategies.
The LFP Conundrum
Lithium-Iron Phosphate (LFP) batteries now claim >70 % of new EV-cell capacity in China, thanks to:
- Lower cost (no Co and Ni)
- Superior thermal stability
- Longer cycle life
- Chemistry advancement : LMFP
Over the last 2 years LFP has gained traction not only in China but globally. Given, LFP know-how is now on the restricted list suggests China isn’t just protecting traditional cathodes; it’s cementing its lead in the fastest-growing segment of the battery market.
Co-Lateral Damage : Semiconductors
Applications of REE extend beyond batteries and EV components. China added Gallium and Germanium to its export control list in July 2023. Gallium & Germanium: Require licenses for raw and processed exports both of which are key materials in chip manufacturing.
Conclusion: Building Resilient Supply Chains
This rising geopolitical and supply chain tension is a wake-up call for all the players across the globe. With China ahead in almost every aspect ( R&D , manufacturing , refining capacity , recycling) OEMs outside China face a monumental challenge in staying competitive and relevant. They must adapt quickly in order to survive or rely on market leaders. For global players, the path forward is clear
- Invest in local refining & recycling to bypass export barriers.
- Develop in-house cathode & process expertise to avoid license bottlenecks.
- Foster cross-border R&D partnerships that can adapt quickly to policy shifts.
- Before making long-term decisions, OEMs outside China should closely assess their unique market needs, resources, and infrastructure. A region-specific, data-driven strategy—rather than copying China’s model—will be key to sustainable growth and supply chain resilience.
In an era where 85–91 % of critical-minerals refining sits behind one wall, true supply-chain resilience demands both diversification and deep technical capability.
