CXMT Is the Seventh Chinese Firm to Sue the Pentagon Over the 1260H List

Changxin Memory Technologies, China's largest maker of DRAM, sued the US Department of Defense in the District of Columbia on 28 August 2026, challenging its designation as a Chinese military company under Section 1260H. Wire coverage reached Asia early on the 29th.

What the list is

Section 1260H requires the Pentagon to publish an annual list of Chinese military companies operating in the United States. Its legal effect is a bar on Department of Defense contracting with the listed entity, phased in over following years. It is not administered by the Commerce Department, it carries no licensing requirement, and it does not restrict CXMT from selling memory to anyone.

What the notice says about CXMT

The published reasoning for the June designation runs to roughly two lines and rests on ownership and affiliation — links to Chinese state industrial and asset-supervision bodies. It asserts no military end use, names no defence programme, and identifies no product supplied to the People's Liberation Army. Whether affiliation alone satisfies the statute is the question the suit puts to the court.

What the common framing gets wrong

Two things. This is repeatedly written up as a novel escalation following a similar filing by another Chinese tech giant; it is the seventh such suit, after actions by drone, lidar, module, memory, pharmaceutical and e-commerce companies, and several earlier plaintiffs won removal. And the list is routinely conflated with export controls — the entity list, the foreign direct product rule, equipment restrictions. Those are Commerce instruments and bite on what a company may buy. 1260H bites on what the Pentagon may buy. Headlines reading "US blacklists China's biggest memory maker" describe a different sanction from the one being litigated.

The detail in the file history

The Pentagon published a notice removing CXMT from the list in February 2026 and withdrew it the same day, then designated the company again in June. A reversal inside a single day is unusual in an annual statutory listing, and it is the kind of record that arbitrary-and-capricious arguments are built from.
