ChangXin Memory Technologies (CXMT), China’s largest manufacturer of dynamic random-access memory (DRAM) chips, has filed a legal complaint against the United States Department of Defense in a Washington federal court. The legal action challenges the company’s designation on the Pentagon’s Section 1260H list, highlighting ongoing trade friction across the global semiconductor supply chain.
The complaint names U.S. Defense Secretary Pete Hegseth as a defendant and asks the court to order CXMT’s removal from the military list. The company argues that the decision to classify it as a military-linked entity was arbitrary, lacked proper evidence, and failed to follow due process.
CXMT stated that it operates independently and produces standard DRAM chips solely for commercial and civilian products, including smartphones, consumer electronics, and computing hardware. The Hefei-headquartered memory producer noted that it spent more than twelve months sharing technical documentation and corporate records with the Department of Defense to clear its name. According to the court filing, the Pentagon issued a formal delisting notice in February but withdrew the notice on the same day without explanation.
CXMT was first added to the Section 1260H registry in January 2025 and remained on the list after an administrative review in June. While this specific listing does not enforce a full export embargo, it prevents the U.S. military from contracting directly with listed firms. Furthermore, these procurement limits are scheduled to extend into broader defense supply chains by June 2027. In practice, the designation creates major commercial hurdles by causing global banks, component suppliers, and multinational device makers to reconsider their business relationships with listed vendors.
The lawsuit comes at a time when global electronics manufacturers depend heavily on stable, diversified memory component sourcing. Industry analysts note that standard DRAM chips are foundational building blocks for everyday technology products, making regulatory clarity vital for international supply networks.
CXMT’s filing follows a series of similar court challenges by other Chinese technology firms seeking relief under U.S. administrative law. Legal experts point out that American courts have shown willingness to examine government justifications carefully. Recent cases involving companies such as lidar developer Hesai Group, drone maker DJI, and biotechnology firm WuXi AppTec have seen federal judges scrutinize whether state ties alone justify defense-related blacklists.
Legal specialists believe the CXMT case will serve as an important benchmark. It will test whether general interactions with regulatory agencies justify security designations, and how U.S. courts evaluate due process protections for international technology manufacturers operating in commercial markets.
