China's top DRAM maker CXMT sues Pentagon over blacklisting, argues chips are civilian-grade

CXMT, China's leading DRAM producer, has filed a lawsuit against the U.S. Department of Defense in an attempt to overturn its classification as a company linked to China's military, according to Reuters. The company argues it has no connection to the People's Liberation Army and that the Pentagon's decision lacked supporting evidence, violated due-process requirements, and has damaged its business and reputation.

The Pentagon first designated CXMT as a Chinese military company in January 2025 under the Biden administration. The Trump administration maintained the classification when the list was updated in June. CXMT says it spent more than a year supplying information to the Defense Department in an effort to be removed from the list.

The company claims the DoD published a notice in February indicating it would be taken off the list, but withdrew the notice later the same day without explanation. In June, the Pentagon classified CXMT as 'directly affiliated with MIIT and indirectly affiliated with SASAC and MIIT'—MIIT being China's Ministry of Industry and Information Technology, and SASAC the State-owned Assets Supervision and Administration Commission.

While CXMT's memory can certainly be found in systems used by the PLA or China's security services, the company argues this does not automatically make it a direct military supplier. The Pentagon's original motivation included a 'military grade' argument: a 2024 report cited an advertisement describing CXMT products as 'military grade.' CXMT says that advertisement came from an unauthorized distributor, which later admitted the characterization was erroneous.

CXMT also claims its DRAM products conform to JEDEC commercial standards and lack the requirements imposed on Chinese military-grade semiconductor components regarding temperature, packaging, testing, and military oversight. The company says that if its products were made in the U.S., they would be classified as 'purely civilian uses,' and that it 'does not hold any licenses to manufacture products for military use.'

Inclusion on the Pentagon's list can lead to restrictions on U.S. government contracts—though CXMT says it barely seeks such contracts—and more importantly, it can affect commercial relationships and reputation. CXMT claims the designation has continually harmed it commercially and reputationally since January 2025, and that the lawsuit is intended to protect its business interests.

Why This Matters

The outcome could set a precedent for how Chinese tech companies challenge U.S. national security designations, affecting dozens of other firms on the Pentagon's list.
CXMT is a major global DRAM supplier; its blacklisting could disrupt supply chains for consumer electronics, data centers, and even Western companies that rely on competitive memory pricing.
The case highlights the growing tension between U.S. efforts to curb Chinese military-linked technology and the commercial reality of dual-use semiconductor components.

Background

CXMT is China's primary producer of DRAM, the type of memory used in virtually all computers, smartphones, and servers. The Pentagon maintains a list of companies it identifies as 'Chinese military companies' under Section 1260H of the National Defense Authorization Act. Inclusion on the list does not impose automatic sanctions but can trigger restrictions on U.S. government contracts and deter civilian business partners who wish to avoid association with Chinese military entities. The list has been a source of sustained legal and diplomatic friction since it was expanded in recent years.

Key Perspectives

CXMT: A purely civilian DRAM manufacturer that has been unfairly blacklisted based on flimsy evidence—an unauthorized distributor's erroneous 'military grade' claim—and denied due process. The company argues its products meet international commercial standards and it lacks military production licenses.

U.S. Department of Defense: The designation is based on CXMT's structure (reportedly affiliated with state-owned entities MIIT and SASAC) and the reality that its memory chips end up in systems used by the PLA. From the Pentagon's standpoint, CXMT is a part of China's broader defense industrial base, even if it supplies civilian customers.

Critics/Skeptics: Some may argue that even if CXMT's products are civilian-grade, the company's state-owned ties and the PLA's ability to use any available commodity chip make the blacklisting understandable. Others may note that the Pentagon's process has been inconsistent—as shown by the withdrawn February delisting notice—raising questions about its reliability.

What to Watch

Whether the court issues an injunction to remove CXMT from the list while the case proceeds, which would signal the strength of the company's due-process arguments.
The Pentagon's response to CXMT's claim that it spent more than a year providing information without resolution—this could reveal either administrative dysfunction or deliberate obstruction.
Potential ripple effects on other Chinese tech companies considering similar lawsuits, particularly those with civilian profiles but state-linked ownership.
