Key Events Sparking Global Alarm
October 8, 2025: The U.S. Department of Commerce’s Bureau of Industry and Security (BIS) added 16 Chinese entities to its Entity List, including three Hong Kong addresses—a move signaling heightened scrutiny over technology exports.
October 9, 2025: China retaliated with dual export restrictions on rare earth mining, smelting, and magnet manufacturing technologies. Any foreign product containing Chinese-sourced rare earths exceeding 0.1% by value or using Chinese extraction techniques now requires Beijing’s approval for re-export.
This tit-for-tat escalation marks a new phase in the U.S.-China tech war, targeting industries vital to national security and consumer electronics.
Why Rare Earths Matter for Displays
Rare earths—17 elements critical to modern technology—are at the heart of global display manufacturing. China’s latest controls focus on five elements (including europium, terbium, and yttrium), with applications spanning:
1. LED/OLED Screens
Europium (Eu): Enables vibrant red hues in OLED/QLED displays (critical for >NTSC 120% color gamut).
Scandium (Sc): Enhances LED efficiency and lifespan.
Ytterbium (Yb): Lowers energy consumption in OLED cathodes, boosting resolution and battery life.
| Rare Earth Elements | Main Roles in Screens |
|---|---|
| Europium (Eu) | Used to provide red light emission; it is one of the key elements for LED displays to achieve high color gamut coverage. |
| Terbium (Tb) | Mainly contributes green light emission and can effectively enhance the color saturation and vividness of the screen. |
| Yttrium (Y) | Commonly used in phosphors and is also an important component of screen light – emitting materials. |
| Lanthanum (La) | Used to manufacture optical glass with high refractive index and low dispersion, widely applied in mobile phone camera lenses and screens to improve imaging quality. |
| Ytterbium (Yb) | In advanced OLED displays, used as a metal cathode material, which can reduce energy consumption and enhance screen resolution and color saturation. |
| Scandium (Sc) | As one of the rare earth elements, it is a core material member of LED displays. |
| Praseodymium (Pr) | Works together with other rare earth ions for color display on screens. |
2. Glass and Optics
Lanthanum (La): Strengthens smartphone camera lenses and screen glass with high refractive indexes.
Cerium (Ce): Polishes glass to ultra-smooth finishes for flawless displays.
3. Broader Industrial Uses
Rare earths also power magnets, lasers, batteries, and defense systems—making them “industrial vitamins” for tech and national security.
Global Supply Chain Vulnerabilities
China’s Dominance: The country controls 90% of global rare earth refining capacity, with limited alternatives in the U.S., Australia, or Myanmar.
Tightening Grip: New rules extend to:
- Full supply chain control: Mining, processing, and recycling technologies.
- Long-arm jurisdiction: Overseas products using Chinese rare earths (>0.1% content) require Beijing’s approval for third-country exports.
- Military/tech targeting: Stringent oversight for chips, AI, and defense applications.
Immediate Risks for Display Manufacturers
Price Volatility: Rare earths like dysprosium saw a 300% price surge during 2020–2021 trade tensions. Europium compounds could face similar hikes.
Supply Chain Disruptions: Delays or shortages threaten 8K HDR panels, OLED rollouts, and high-end smartphone displays.
R&D Setbacks: Alternative materials (e.g., perovskites) lag behind rare earth-based solutions in efficiency and scalability.
Industry Reactions
Apple Supplier Foxconn: Warns of “unprecedented disruptions” to MacBook Pro display shipments.
Samsung Display: Redirects 30% of europium orders through Vietnam.
Experts: French economist Alicia Garcia-Herrero calls the move a “calculated strike” on global tech value chains, while MIT researchers urge accelerated recycling initiatives.
Long-Term Implications
Geopolitical Shifts: The U.S. and allies may ramp up investments in Australian, African, or domestic rare earth projects.
Technological Innovation: Pressure mounts to develop synthetic alternatives or reduce reliance on China.
Sustainability Focus: Closed-loop recycling systems (e.g., Japan’s Eco-Display Initiative) gain traction.
Conclusion
China’s rare earth controls are more than a trade dispute—they’re a reset of global tech power dynamics. For display manufacturers, the choice is clear: adapt to a fragmented supply landscape or lead the charge toward material independence.
