Sou Hu Cai Jing·2025-10-12 09:27Core Viewpoint - The recent export control regulations by China on rare earth materials and technologies significantly impact the semiconductor industry and other high-tech sectors in the U.S. [1][3][4] Group 1: New Regulations and Their Implications - On October 9, China's Ministry of Commerce announced new regulations that impose export controls on certain rare earth-related items and technologies containing Chinese components [1]. - The new rules require foreign manufacturers to obtain permission from China to sell rare earth magnets and semiconductor materials that contain 0.1% or more of Chinese heavy rare earth elements [1][3]. - The regulations particularly affect the semiconductor industry, as they require applications for the use of Chinese rare earth materials in the production of advanced chips and military-related AI technologies [3][4]. Group 2: Impact on Semiconductor Manufacturers - TSMC, the world's leading semiconductor foundry, relies heavily on rare earth elements for chip manufacturing, which are primarily imported from mainland China [4][6]. - If TSMC uses Chinese rare earth elements in producing chips below 14nm, it will need Chinese permission to sell these chips to U.S. companies like Apple and Intel [4][6]. - The potential inability to source these materials could lead to significant challenges for U.S. chip manufacturers, affecting their production capabilities [6]. Group 3: Broader Implications for U.S. Industries - The U.S. military and aerospace sectors also heavily depend on rare earth elements, which are critical for various advanced weapon systems and technologies [6][7]. - For instance, the F-35 fighter jet requires 417 kg of rare earth materials, and a Virginia-class submarine needs 4600 kg, highlighting the extensive reliance on these materials [6]. - The automotive industry, particularly electric vehicles like those produced by Tesla, also utilizes rare earth elements in their manufacturing processes [6]. Group 4: China's Dominance in Rare Earth Production - China accounts for approximately 70% of global rare earth production and over 90% of rare earth refining capacity, particularly in heavy rare earths, where it holds more than 98% of the global market share [10][11]. - The technical expertise in rare earth processing and purification is predominantly held by China, making it difficult for other countries to establish competitive production capabilities [12][14]. - The U.S. has been unable to significantly improve its rare earth production and technology despite efforts to develop its own supply chain since 2010 [18][20]. Group 5: Challenges for U.S. Rare Earth Initiatives - The U.S. faces significant challenges in re-establishing its rare earth supply chain due to high production costs and environmental risks associated with rare earth mining [21][22]. - Many U.S. companies are reluctant to invest in rare earth mining and processing due to the potential for high costs and environmental liabilities [21][22]. - Collaborative efforts with other countries to develop rare earth industries have been slow and may take decades to yield results, leaving the U.S. reliant on Chinese imports in the near term [23][24].
