The US Department of Transportation has flagged Ford's partnerships with Chinese giants CATL, Geely, and BYD as national security risks, triggering a significant drop in the automaker's stock price.

  • US Transportation Secretary Sean Duffy warned Ford CEO Jim Farley about security risks tied to Chinese partnerships.
  • Concerns center on CATL's battery production in Michigan and joint ventures with Geely and BYD.
  • Ford's stock plummeted by 4.2% following the disclosure of the warning letter.

In a significant escalation of trade tensions between Washington and Beijing, the United States Department of Transportation (DOT) has issued a stern warning to Ford Motor Company. In a letter addressed to CEO Jim Farley, Transportation Secretary Sean Duffy asserted that the automaker's deep-rooted partnerships with Chinese entities pose substantial national security risks.

A primary point of contention is Ford's collaboration with CATL, a global battery leader, at its Marshall, Michigan plant for the production of lithium-iron-phosphate (LFP) battery cells. The DOT argued that relying on Chinese technical expertise, even in a limited capacity, undermines the spirit of American economic security and the goal of achieving supply-chain independence. It is noteworthy that CATL was previously banned by the US Department of Defense in January 2025.

Why This Matters

BozokMedia analysis shows that this move signals a shift from general trade tariffs to targeted operational scrutiny. The US government is no longer just taxing imports; it is actively auditing the internal supply chains of domestic champions like Ford. This creates a precarious position for automakers who rely on Chinese efficiency to remain competitive in the global EV transition while facing immense political pressure to 'de-couple'.

"Supply chain sovereignty is no longer just an economic goal; it is now a core pillar of national defense strategy."

The DOT's concerns extend beyond batteries. Secretary Duffy highlighted Ford's joint venture with Geely in Spain, suggesting it provides strategic adversaries a "vital foothold" in Western markets. Furthermore, ongoing discussions with BYD regarding hybrid vehicle components were criticized for potentially embedding subsidized foreign technology into Ford's core operational framework.

While Ford has committed to moving the production of the Lincoln Nautilus from China to the US by 2030, the DOT dismissed this timeline as insufficient. The letter stated that this transition leaves an "unacceptable, multi-year window of reliance" on Chinese manufacturing, which the government views as a strategic vulnerability.
