CXMT, China’s largest DRAM maker, has taken the U.S. Department of Defense to court in a bid to reverse its designation as a company tied to the Chinese military. ChangXin Memory Technologies argues it has no links to the People’s Liberation Army and says the Pentagon’s decision lacks supporting evidence, failed to meet due-process standards, and has harmed both its business and reputation.
The dispute centers on memory chips that CXMT insists are ordinary civilian products built to JEDEC commercial specifications rather than defense hardware. The outcome could shape how American companies weigh their relationships with one of China’s fastest-growing semiconductor firms.
How the Designation Unfolded
The Pentagon first labeled CXMT a Chinese military company in January 2025, during the Biden administration. The Trump administration kept the designation in place when the Defense Department refreshed its list in June. CXMT says it spent more than a year submitting information to the department in an effort to be removed.
According to the company, the Defense Department published a notice in February signaling that CXMT would be dropped from the list, only to withdraw that notice the same day without explanation. By June, the Pentagon described CXMT as “directly affiliated with MIIT and indirectly affiliated with SASAC and MIIT.” MIIT refers to China’s Ministry of Industry and Information Technology, while SASAC is the State-owned Assets Supervision and Administration Commission of the State Council, which formally holds the government’s stakes in non-financial state-owned enterprises.
The ‘Military Grade’ Argument at the Center of the Case
CXMT contends the Pentagon’s original justification was weak. The complaint states that a 2024 Defense Department report claimed CXMT contributed to China’s defense industrial base partly because its DRAM is dual-use, and pointed to an advertisement describing the company’s products as “military grade.” CXMT says that advertisement came from an unauthorized distributor that later acknowledged the label was a mistake.
The company further argues that its DRAM products meet JEDEC commercial standards and lack the requirements applied to Chinese military-grade semiconductor components in areas such as temperature tolerance, packaging, testing, and military oversight. CXMT adds that if its products were manufactured in the United States, they would be classified for “purely civilian uses,” and that it holds no licenses to produce components for military use.
What the Blacklisting Means for Business
While the memory in some systems used by the PLA or Chinese intelligence services may include CXMT chips, the company argues this does not make it a direct supplier to those entities or prove it is a military firm.
Placement on the Pentagon’s list can trigger restrictions on U.S. government contracts, a market CXMT says it barely pursues. The larger concern is commercial fallout, since many firms avoid partnerships with companies tied to the Chinese military. CXMT states that the designation has continuously damaged it commercially and reputationally since January 2025, and that the lawsuit is meant to protect its business interests.
