CXMT Sues Pentagon Over Military Company Designation
ChangXin Memory Technologies (CXMT), China’s leading dynamic random-access memory (DRAM) chipmaker, has sued the U.S. Department of Defense in federal court seeking removal from the Pentagon’s list of companies linked to China’s military. The lawsuit, filed in the U.S. District Court for the District of Columbia, challenges a designation CXMT says is unsupported by evidence and has damaged its commercial prospects in the United States.
The Defense Department first designated CXMT under the Section 1260H framework in January 2025. CXMT said it spent more than a year providing information to the Pentagon to challenge the designation before the department briefly indicated in February 2026 that it would remove the company, withdrew that notice the same day and subsequently retained CXMT on the list in June.
CXMT said in its complaint that the designation was “arbitrary,” lacked evidentiary support and violated its due-process rights. The Pentagon has declined to comment on the pending litigation.
CXMT Challenges Pentagon’s Evidence
CXMT has rejected any military affiliation and said in its lawsuit that it “designs, produces, and sells its DRAM chips for civilian and commercial use, not for military use.” The company is asking the court to overturn the designation and remove it from the Pentagon’s list.
The Pentagon’s current 1260H framework requires the department to identify companies it determines are Chinese military companies operating directly or indirectly in the United States. The department’s own guidance says the designation can affect contracting eligibility for covered organizations.
CXMT’s complaint also challenges the process used to maintain its designation. The company said it submitted information for more than a year but that the Pentagon ultimately reinstated the listing in June without adequately explaining its change in position.
US-China Semiconductor Dispute Reaches Court
The lawsuit comes as Washington continues to scrutinize Chinese semiconductor companies over national-security concerns. In July, U.S. senators said the Pentagon had designated both CXMT and Yangtze Memory Technologies as Chinese military companies under Section 1260H and urged Apple not to use their memory chips.
CXMT’s legal challenge follows similar litigation by Chinese companies facing Pentagon designations. Alibaba sued the U.S. government in June over its placement on the same type of list, while Xiaomi successfully challenged its designation in U.S. federal court in 2021 and secured removal.
The legal disputes have therefore created a separate avenue for Chinese technology companies to challenge U.S. national-security designations. For CXMT, the court case could determine whether the Pentagon must provide a stronger evidentiary and procedural basis for keeping the company on the list.
CXMT’s Rapid Growth Raises Stakes
The lawsuit comes days after CXMT reported a sharp increase in first-half revenue. A Shanghai Stock Exchange filing showed revenue of 150.31 billion yuan ($22.4 billion) for the six months ended June, up 873.64% from a year earlier.
CXMT also reported first-half net profit of 77.61 billion yuan, compared with a loss of about 2.3 billion yuan in 2025, according to its financial disclosure. The company attributed the stronger performance to higher memory prices and increased sales amid rising demand for computing capacity.
The financial improvement increases the commercial significance of CXMT’s dispute with Washington. The company has stated an ambition to enter the U.S. market over the longer term, while its Pentagon designation creates additional restrictions and reputational risks around potential U.S. business relationships.
What the Court Decision Could Mean
A ruling for CXMT could provide a legal route for other Chinese technology companies to challenge Pentagon designations rather than relying solely on administrative appeals. Xiaomi’s 2021 case provides a precedent for such challenges, although the circumstances and legal arguments in CXMT’s case will be determined by the court.
The case also places CXMT’s rapidly expanding memory business directly against Washington’s national-security policy. U.S. lawmakers have argued that CXMT and other Chinese memory producers pose security risks, while CXMT maintains that its products are intended for civilian and commercial applications.
For CXMT, removal from the list would eliminate one significant U.S. regulatory and reputational obstacle as the company expands globally. The court will now determine whether the Pentagon’s designation survives the company’s challenge.
