U.S. AI Data Center Supply Chain Deeply Reliant on China; Trump Signs Executive Order in Response
nashnova research
The power equipment behind America's AI data centers — transformers, switchgear, batteries — is heavily sourced from China. Trump last week declared a national emergency and authorized the Energy Department to restrict related transactions. This means → the AI buildout race has spread from the compute layer to the power layer, turning supply-chain security into a new front.
Why can't data centers quit Chinese suppliers?
US hyperscale data centers are expanding on a hundreds-of-billions-of-dollars trajectory, yet core power equipment — transformers, switchgear, batteries — is heavily sourced from China.
Transformers — devices that step down high-voltage transmission power to levels a data center can use — are the most exposed link: hyperscalers typically deploy on-site substations whose key components come from Chinese suppliers.
Optical technology is similarly concentrated. According to Counterpoint, Innolight and HGTECH lead global data-center transceiver revenue; Chinese firms supply roughly two-thirds of global units.
This means → the chokepoint for US AI infrastructure isn't just chips — it's the power-access layer that must work before any chip can run.
How deep does the dependence go?
Johns Hopkins associate professor Yury Dvorkin notes that China holds close to 30% of certain transformer and switchgear categories, and accounts for over 40% of US battery imports.
Upstream exposure runs deeper still — copper, electrical steel (the specialty steel used in transformer cores), and battery cathode materials are also heavily China-dependent.
In plain terms = it isn't just finished equipment bought from China. The raw materials to *make* that equipment are locked into Chinese supply chains too — "de-risking" means unwinding not one layer but several.
What does Trump's executive order actually do?
Trump last week signed an executive order declaring that foreign-made bulk-power-system equipment poses an "extraordinary foreign threat" to the US, formally invoking a national emergency.
The order authorizes the Department of Energy to prohibit or conditionally approve specific transactions involving grid and data-center components.
Trump stated: "Since my first term, the threat to the United States from foreign supply of bulk-power-system electrical equipment has only grown more severe."
This means → the policy toolkit has moved from "monitoring" to "can block deals outright" — but scope and enforcement hinge on follow-up rules yet to be written.
Why is the power layer only now getting attention?
Economist Group senior analyst Laveena Iyer told CNBC that scrutiny of China's role in the US data-center power layer has intensified over the past eight months — a shift from the earlier focus on the compute layer (chips, GPUs).
S&P Global forecasts US data-center capacity will grow from 62 GW in March 2026 to 152 GW by 2030 — more than doubling in under four years.
This reflects a turning point: the AI compute explosion is forcing a surge in power demand, yet power-equipment supply-chain security had barely been questioned until now.
Can "de-risking" outrun the pace of data-center expansion?
The White House says reshoring critical manufacturing is "the President's top priority," pursued through a combination of tax cuts, tariffs, and deregulation.
The core question remains: can domestic replacement capacity for transformers and similar equipment come online fast enough to match the data-center buildout window?
In plain terms = the policy direction is clear, but factories don't materialize by executive order. This is a race between "how fast can we build plants" and "how fast are data centers going up" — and nobody yet knows who crosses the finish line first.
