New restrictions on China's rare earths are expected to disrupt technology and defense industries

China's new export rules for rare earths create global tech and defense industry challenges.

: China's introduction of export licensing requirements for seven rare earth elements, including scandium and dysprosium, is expected to disrupt technology and defense sectors. These materials are critical for producing components in smartphones, electric vehicles, and military technology, with their supply chain domination resulting from decades of infrastructure investments. The strategic move appears to respond to rising U.S. trade tensions, exerting global influence over rare earth-dependent markets. Efforts to diversify supply chains include initiatives by nations like Australia and Vietnam to reduce reliance on Chinese exports.

China's recent implementation of additional restrictions on the export of rare earth elements highlights its strategic dominance in the global supply chain for critical materials used in advanced technology and defense systems. This move targets seven essential elements, including scandium and dysprosium, vital for manufacturing high-performance telecom devices, electric vehicles, and military technology. The increased bureaucratic measures, such as requiring licenses and usage specifications for the exportation of these elements, are likely to obstruct supply chains, increase costs, and impact global industries reliant on these materials.

Rare earth elements possess unique chemical and physical properties that enhance technological products. Scandium's role in forming Scandium Aluminum Nitride significantly improves signal strength in telecom equipment, while dysprosium bolsters the thermal stability of magnets in electric vehicle motors and MRAM devices. Despite their importance, finding substitutes for these materials can lead to performance declines and increased production costs, posing substantial challenges to manufacturers and developers.

China's extensive investment over decades in the mining, refining, and processing of rare earth materials has resulted in it producing about 70 percent of global output and over 85 percent of refined versions of these elements. Although these minerals are not geographically rare, their extraction and refining require significant resources; hence, China's efficiency has allowed it to monopolize these markets, creating strategic leverage against geopolitical adversaries.

The new restrictions are largely perceived as China's responsive action to ongoing trade tensions with the United States, which started to intensify after tariffs imposed during the Trump administration. These limitations follow previous export controls affecting other materials crucial for semiconductor manufacturing, like gallium and germanium. The current situation signals potential disruptions for major semiconductor manufacturers, with prices anticipated to rise significantly amid short-term supply chain challenges.

Several countries are actively seeking to reduce their dependency on Chinese exports by developing alternative sources and technologies. For instance, Japan has managed to cut down its reliance from 90 to 60 percent by investing in local mining operations and partnerships with collaborators like Australia's Lynas Corporation. While diversification efforts are underway, China's entrenched control over rare earth production persists, posing continuing risks to global industries.
