Chinese Chipmaker CXMT Challenges Pentagon Blacklist in Federal Court

Leading Chinese semiconductor manufacturer ChangXin Memory Technologies (CXMT) has initiated legal action against the U.S. Department of Defense, seeking to be removed from a federal blacklist that identifies the firm as a Chinese military company. The lawsuit, filed in the U.S. District Court for the District of Columbia, names Secretary of Defense Pete Hegseth as a defendant and challenges the accuracy of the government's classification.

In its court filing, the company asserts that it has no ties to the Chinese military. CXMT maintains that its DRAM memory chips are developed exclusively for commercial and civilian applications. The firm argues that the Pentagon's designation is factually incorrect and has caused significant reputational and commercial damage since the company was first added to the restricted list in January 2025.

This legal challenge follows a pattern of similar actions by other Chinese technology firms, such as DJI and Hesai Group, which have also sought to contest their inclusion on U.S. government watchlists. Legal experts have noted that recent judicial trends suggest U.S. courts are increasingly willing to scrutinize the evidence provided by the Department of Defense when companies challenge these administrative designations.

While the Pentagon has maintained its policy of not commenting on active litigation, the case highlights the ongoing tensions surrounding U.S. trade restrictions on Chinese technology. CXMT, which remains a major player in the memory chip sector, is pushing for a reversal of the label to mitigate the impact of potential government contracting restrictions and to restore its standing in the global market.
