Highlights

• China restricts exports of seven additional rare earth elements.
• This restriction dramatically increases global prices.
• The restriction threatens technology supply chains.
• The semiconductor, electric vehicle, and defense industries face significant challenges.
• China controls nearly 99% of critical mineral refinement.
• Current alternatives and diversification efforts are insufficient.
• There is an inability to mitigate potential strategic and economic vulnerabilities immediately.

China’s latest move in the escalating trade war—imposing April 2025 export restrictions on seven additional rare earth elements—has sent shockwaves across industries reliant on critical materials. Samarium, gadolinium, terbium, dysprosium, lutetium, scandium, and yttrium now join gallium, germanium, and antimony on a growing list of constrained exports. Prices for these medium and heavy rare earths have reportedly doubled or tripled within weeks, threatening higher costs for semiconductors, electric vehicles (EVs), renewable energy systems, and military technologies.

With China controlling nearly 99% of global gallium refining and over half of germanium output, the West faces a stark supply chain reckoning. Efforts like the U.S.-Ukraine minerals agreement and an expected U.S.-Saudi rare earth deal are long-term plays at best, while nascent recycling programs—from Taiwan to the Pentagon’s Tobyhanna Depot—remain years away from scale.

Industry voices are sounding the alarm. As reported by Peter Brown in Electronics 360: MEMS and Sensors (opens in a new tab), Adam Carter of OpenLight warns the semiconductor sector is “particularly sensitive to supply shortages,” and Deloitte’s Duncan Stewart predicts worsening restrictions throughout 2025. Proposed solutions—diversifying supply, recycling, building reserves—will take time, capital, and geopolitical stability, which the current climate does not offer. While alternatives like silicon or indium exist, they are either insufficient or too costly for high-performance applications.

The article clearly leans on expert speculation, especially regarding the pace and efficacy of replacement strategies, and subtly mirrors a Western industry narrative of helplessness in the face of Chinese dominance. Nonetheless, the core warning is clear: without a rapid policy and industrial response, consumers and defense sectors alike will face rising costs, delayed production, and strategic vulnerabilities.
