Should the U.S. prioritize restricting foreign hardware imports even if it raises infrastructure project costs?
On August 26, 2026, President Donald Trump signed Executive Order 14421 to restrict Chinese-made hardware in the U.S. power grid. The order targets components including battery systems, transformers, and inverters.
Why it matters
The action seeks to mitigate national security risks stemming from reliance on foreign infrastructure in vital AI data centers. It forces a supply chain transition for critical energy technology.
China supplied 50% of U.S. lithium-ion battery imports in the 12 months ending June 2026, while South Korea, Mexico, and Canada combined for 74% of circuit breaker imports and 48% of transformer imports.
The players
Donald Trump
Donald Trump is the current President of the United States who signed the order to address energy grid security.
Hyosung Heavy Industries
Hyosung Heavy Industries is a South Korean manufacturer that signed contracts to supply ultra-high-voltage transformers for U.S. hyperscalers.
The details
The order mandates stricter oversight for substation transformers, grid-connected inverters, battery storage systems, and circuit breakers. Federal rulemaking to define prohibited ownership structures is required by December 24, 2026.
Timeline
August 26, 2026: President Donald Trump signed Executive Order 14421.
September 15, 2026: Hyosung Heavy Industries secured U.S. transformer contracts.
December 24, 2026: Deadline for federal rulemaking regarding equipment scope.
Roadmap
This move signals a broader transition in the U.S. automotive and tech sectors toward regionalized energy infrastructure supply chains. By favoring suppliers in South Korea, Mexico, and Canada, the order forces hyperscalers to decouple from long-standing reliance on Chinese hardware.
Data center operators and energy providers may face increased procurement costs as they shift to non-Chinese suppliers for transformers and battery systems. These shifts could influence the timeline for expanding power capacity for regional AI infrastructure.
The takeaway
The executive order significantly reshapes the procurement landscape for U.S. tech firms managing energy-intensive infrastructure. Businesses should prepare for rigorous vetting processes as federal definitions for compliant supply chains are finalized later this year.
What happens next
Federal agencies must complete the formal rulemaking process to define the scope of Covered Foreign Entity ownership by December 24, 2026.
