The advancement of AI in mining technology is also helping to optimize the extraction and processing of these vital materials.

Key Elements in Rare Earth Magnets

The exceptional performance of rare earth magnets stems from their unique elemental composition:

• Neodymium (Nd): The primary light rare earth element providing the fundamental magnetic properties in standard NdFeB magnets
• Dysprosium (Dy): A heavy rare earth element added in concentrations of 3-12% to enhance temperature resistance and prevent demagnetization at higher operating temperatures
• Terbium (Tb): Another heavy rare earth element used in smaller quantities that significantly improves coercivity and temperature stability
• Praseodymium (Pr): Often used as a partial substitute for neodymium (up to 25%) to optimize cost and performance
• Iron (Fe) and Boron (B): Non-rare earth components that complete the alloy structure and contribute to the overall magnetic properties

The composition of these magnets varies depending on the intended application, with high-temperature applications like EV motors requiring higher concentrations of dysprosium and terbium to maintain performance at operating temperatures that can exceed 150°C.

How Is China Dominating the Rare Earth Magnet Industry?

The Extent of Chinese Market Control

China's dominance in the rare earth magnet supply chain has evolved over decades through strategic investments, research prioritization, and vertical integration. The country currently controls approximately 85% of the world's rare earth processing capacity and over 90% of high-performance magnet manufacturing.

This market concentration isn't merely a result of China's abundant geological resources but represents a deliberate national strategy. While China possesses approximately 35% of global rare earth reserves, its control over processing and manufacturing far exceeds its share of raw materials, demonstrating the country's focus on higher-value segments of the supply chain.

Chinese rare earth magnet producers benefit from significant advantages, including established infrastructure, specialized expertise, economies of scale, and favorable regulatory environments regarding environmental compliance and intellectual property requirements. The US‑China trade impacts have further complicated this landscape, creating additional challenges for Western nations seeking to reduce dependence.

Recent Export Restrictions and Market Impacts

In 2023-2024, China implemented new export controls on several medium and heavy rare earth elements, including dysprosium and terbium, as well as the magnets containing them. These restrictions represent a significant escalation in supply chain risk, as they directly target the highest-value segments of the rare earth market.

The restrictions have triggered significant price volatility, with dysprosium oxide prices increasing by approximately 40% and terbium oxide by 35% in the months following the announcement of control measures. This price movement reflects market uncertainty about future supply availability and regulatory implementation details.

"These export controls signify China's continued strategic approach to rare earth resources, reinforcing the urgent need for supply chain diversification," noted a senior market analyst from a leading commodities intelligence firm.

The timing of these restrictions coincides with accelerating efforts by Western nations to secure non-Chinese supply chains, suggesting a complex interplay between supply security concerns and strategic resource leveraging. According to a recent report from The Guardian, China's stranglehold on the global rare earths supply chain presents significant challenges that countries like Australia are working to overcome.
