Core Viewpoint - The global competition for rare earth resources is intensifying, with China holding a near-monopoly in this sector, while other countries, despite having rich rare earth mineral resources, lack efficient refining technology [1] Group 1: Rare Earth Supply Chain Dynamics - The United States and other countries are increasingly relying on Thailand and Mexico as key transit points to bypass China for rare earth supplies [3] - These countries employ various tactics, including repackaging rare earths to disguise their origin, to facilitate the export of Chinese rare earths to the U.S. [3][5] - The logistics companies involved in this smuggling operation are profiting significantly, with U.S. imports of antimony products from Thailand and Mexico reaching 3,834 tons between December 2024 and April 2025, far exceeding the total from the previous three years [7] Group 2: China's Response and Regulatory Measures - In response to the smuggling and circumvention of export controls, China has implemented unprecedented measures to track rare earths, assigning unique codes to each gram for precise monitoring [11] - Customs authorities in Shenzhen and Hong Kong have been equipped with advanced detection technology to identify disguised rare earth products quickly [11][12] - Following the implementation of these measures, the difficulty for the U.S. to acquire rare earths through illegal channels has increased, leading to a backlog of suspicious containers in Mexican ports and detained rare earth products in Thai warehouses [13] Group 3: Global Implications and Future Outlook - The European Union has recognized the severity of the situation, with the introduction of the Critical Minerals Act aimed at stabilizing supply chains, although European automakers still rely on Chinese rare earth permits due to technological gaps [15] - China has developed a new "dysprosium-free magnet" that is 40% cheaper than traditional materials, potentially setting a new industry standard [17] - The "zero-carbon rare earth" certification system promoted by China is becoming the default standard for global procurement, indicating China's dominant position in the rare earth supply chain [17]
