ChangXin Memory Technologies (CXMT), China’s top maker of dynamic random-access memory chips, has sued the U.S. Department of Defense to overturn its designation as a Chinese military company. The lawsuit, filed in the U.S. District Court for the District of Columbia, names Defense Secretary Pete Hegseth, Deputy Defense Secretary Steve Feinberg and Assistant Secretary of Defense for Industrial Base Policy Michael Cadenazzi as defendants. CXMT says it has no affiliation with the Chinese military and designs, produces and sells DRAM chips for civilian and commercial use. The company argues that the Pentagon’s decision was arbitrary, unsupported by evidence and violated its due-process rights. The designation was made under the Biden administration and retained by the Trump administration in a June update, after the Pentagon withdrew a February notice saying CXMT would be removed. CXMT says the listing has damaged its reputation and business, while the restrictions can bar direct Defense Department contracts and limit third-party purchases starting next year. Its revenue rose 874% in the first half, and it aims to enter the U.S. market over the long term. The case follows similar litigation by Alibaba; Xiaomi won removal from the list in 2021.
