Core Viewpoint - The article highlights a significant increase in the import of antimony oxide by the United States from Thailand and Mexico, which raises concerns about a potential smuggling network involving Chinese enterprises [1][7]. Group 1: Smuggling Operations - Between December 2024 and April 2025, the U.S. imported 3,834 tons of antimony oxide from Thailand and Mexico, surpassing the total of the previous three years [1][7]. - The smuggling operations involve disguising Chinese rare earth materials as other products, such as iron ore and zinc, to evade customs regulations [3][9]. - A Chinese metal chemical company's subsidiary in Thailand reportedly shipped 3,366 tons of antimony products to the U.S. within six months, marking a 27-fold increase year-on-year [5]. Group 2: Economic Implications - The surge in international rare earth prices, which have risen by 200% since 2024, has incentivized some Chinese companies to engage in smuggling for higher profits [11]. - Smuggling profits can reach 3-5 times that of normal trade, creating a vicious cycle that distorts international market prices and attracts more participants into illegal trading [11]. Group 3: Military Supply Chain Vulnerabilities - The smuggling case exposes critical vulnerabilities in the U.S. military supply chain, with a significant reliance on Chinese-produced materials for key weapon systems [12][15]. - Approximately 90% of global rare earth processing capacity is concentrated in China, and over 80% of the U.S. military's rare earth material needs are sourced from China [15]. Group 4: Regulatory Responses - In response to the smuggling issue, China initiated a special action in May 2025 to combat illegal activities related to rare earth exports, including enhanced customs inspections and data sharing with industry associations [19][21]. - New amendments to the Mineral Resources Law have increased penalties for rare earth smuggling, and several cases have already been prosecuted, involving significant quantities of metals [21]. Group 5: Strategic Implications - The ongoing rare earth competition reflects a broader struggle for control over global supply chains, with China leveraging its technological advantages to shape international trade rules [23]. - Efforts by the U.S. to rebuild its supply chain have been largely ineffective, with significant time required to establish independence from Chinese sources [17].

在科技浪潮奔涌向前的当下，5G已然融入生活，6G的研发也在如火如荼推进。这些前沿通信技术 的革新，离不开关键材料的强力支撑，磷化铟便是"幕后英雄"之一。凭借独特的高频性能，它成为通信 领域的"香饽饽"，在国产替代的道路上大步迈进。 陕西澳威激光科技有限公司（以下简称"陕西澳威激光"）对于铜川光电子产业的发展具有特殊的意 义。2018年9月，陕西澳威激光签约入驻铜川新材料产业园区，是该园区首家光电子产业高新技术企 4年前，这样的场景还很难想象。磷化铟作为第二代半导体核心材料，材料性能突出、市场前景广 阔，但合成技术被国外垄断。陕西铟杰技术团队经历数百次失败，最终成功运用CFD流体模拟攻克磷化 铟晶体合成核心技术。2021年，首根具有自主知识产权的磷化铟多晶棒成功出炉，纯度在 99.9999%（6N级）以上，电子迁移率、载流子浓度等指标达到国际一流标准。 "目前，我们公司生产的磷化铟产品质量已通过行业客户验证，产品直供头部企业。过去，国内衬 底厂主要依赖进口，材料成本高，且随时面临断供风险。现在，我们的磷化铟材料产能充足、产品品质 稳定、批次一致性高，为下游企业提供了可靠的材料保障。"张一帆说。 技术突围的背后是 ...
