U.S. moves to curb Chinese components in AI data centers amid supply chain concerns
Federal actions targeting foreign power and optical equipment could exacerbate existing hardware shortages for American data centers.
The short version
- President Donald Trump signed an executive order authorizing the Department of Energy to regulate or restrict foreign equipment used in bulk-power systems and data centers.
- The administration is also reportedly drafting an import ban on Chinese optical transceivers to reduce strategic dependence on Beijing.
- Industry analysts warn that replacing Chinese suppliers could worsen existing hardware shortages and inflate costs for U.S. AI hyperscalers.
- Domestic and Western manufacturers face a 12-to-24-month gap before they can scale up sufficient production capacity to absorb the demand.
Key facts
- President Donald Trump declared a national emergency regarding foreign threats to bulk-power systems, authorizing the Department of Energy to restrict or condition certain equipment transactions for the grid and data centers.[CNBC]
- China accounts for roughly two-thirds of the global unit supply of data center optical transceivers, over 40% of U.S. battery imports, and nearly 30% of certain transformer and switchgear categories.[CNBC]
- Wood Mackenzie estimated power transformers and substations are facing supply shortages of 15% and 8%, respectively, in 2026.[CNBC]
- S&P Global projects U.S. data center capacity to grow from 62 gigawatts in March 2026 to 152 gigawatts by 2030, driven by artificial intelligence workloads.[CNBC]
- Siemens Energy and Hitachi Energy have each announced $1 billion investments to expand U.S. production facilities for electrical grid and power infrastructure.[CNBC]
What remains uncertain
- The final scope and timing of a reported Trump administration ban on Chinese optical transceiver imports remain unconfirmed, as the White House and FCC did not address the reporting.[CNBC]
- Analysts at Counterpoint note it is uncertain whether Western photonic competitors can scale packaging and cleanroom capacity quickly enough to replace Chinese volume within the next 12 to 24 months.[CNBC]
