China's Top Memory Chipmaker CXMT Sues Pentagon Over Military Blacklist Designation

ChangXin Memory Technologies (CXMT), China's largest manufacturer of memory chips, has filed a federal lawsuit against the U.S. Department of Defense. The company is seeking to overturn its designation as a "Chinese military company," arguing the label is baseless and has caused significant commercial damage.

Details of the Legal Challenge

In a complaint filed Friday in the U.S. District Court for the District of Columbia, CXMT asserted that it has no affiliation with the Chinese military. "CXMT designs, produces, and sells its DRAM chips for civilian and commercial use, not for military use," the company stated in the lawsuit.

The chipmaker claims the Pentagon's decision was "arbitrary," lacked evidentiary support, and violated its due-process rights. According to a statement provided to Reuters, CXMT has "continuously suffered reputational and commercial harm" since first being placed on the list in January 2025. The U.S. Defense Department told Reuters it does not comment on pending litigation as a matter of policy.

Background on the Designation

The Pentagon's list of so-called Chinese military companies can subject firms to government contracting restrictions and significant reputational risk, potentially hindering international business operations. CXMT alleges it spent more than a year providing the Pentagon with information to challenge the designation.

The complaint also highlights an unusual incident from February, when the department reportedly published a notice that CXMT would be removed from the list but then withdrew the notice on the same day. CXMT alleges the Pentagon did not adequately explain its reversal.

Market Context and Precedent

As China's top producer of dynamic random-access memory (DRAM) chips, CXMT is a key player in the global semiconductor supply chain for products like smartphones, PCs, and servers. The company, which saw its revenue surge by 874% in the first half of the year, has long-term ambitions to enter the U.S. market, according to Reuters.

CXMT's legal action follows a path taken by other major Chinese corporations. In 2021, electronics giant Xiaomi successfully sued to have itself removed from the same list. More recently, e-commerce and technology firm Alibaba filed a similar lawsuit in June to challenge its inclusion.
