A 100% Buy America Mandate Stalls the $5 Billion Federal EV Charger Network

The great American road trip is undergoing a massive transition as electric vehicles hit the highways, but the infrastructure to support them has hit a bureaucratic bottleneck. At the center of the debate is the National Electric Vehicle Infrastructure (NEVI) program, a $5 billion federal initiative designed to place fast chargers every 50 miles along major interstates. The program was intended to eliminate range anxiety and open up rural corridors to electric travel.[2][4]

In February 2026, the U.S. Department of Transportation, led by Secretary Sean P. Duffy, proposed a sweeping change to the rules governing these funds. The new mandate requires that 100% of the components in federally funded EV chargers be manufactured in the United States, effectively eliminating a previous waiver that capped the requirement at 55%.[1][6]

The Department of Transportation argues that the 100% domestic content rule is essential for national security and economic growth. By forcing companies to onshore their supply chains, the administration aims to create domestic manufacturing jobs and protect critical infrastructure from foreign-made components that could harbor cybersecurity vulnerabilities.[4][6]

To understand the crisis, it helps to look at how the "Buy America" provision actually works. Under the previous framework established in 2023, chargers had to undergo final assembly in the U.S., and their steel or iron enclosures had to be entirely domestic. The internal components, however, were granted a waiver allowing up to 45% of their cost to be sourced internationally.[4][7]

The new proposal removes that buffer. Now, every single component—from the heavy-duty cooling cables to the microscopic printed circuit boards—must be sourced and manufactured domestically for the charger to qualify for federal funding. This strict interpretation applies to all new procurement contracts moving forward.[1][7]

Industry experts and state transportation officials warn that this 100% threshold is currently impossible to meet. While the United States excels at final assembly and steel fabrication, the global supply chain for specialized electronics is deeply entrenched overseas, particularly in Asia.[5][7]

Certain critical parts simply do not have domestic manufacturing equivalents at the scale required. High-voltage contactors, advanced liquid-cooling systems for 350-kilowatt fast chargers, and specific microchips are overwhelmingly produced abroad, and building those specialized factories takes years of capital investment and workforce training.[3][8]

Because no EV charger currently on the market meets the 100% domestic content requirement, the mandate effectively freezes the deployment of NEVI funds. States and municipalities cannot purchase compliant hardware, leaving billions of dollars sitting idle while highway corridors remain without charging stations.[5][7]

For the average driver planning a cross-country EV road trip, this translates to a delayed rollout of reliable fast-charging hubs. The promise of a seamless network connecting rural routes and national parks is pushed further into the future as the industry scrambles to adapt to the new regulatory landscape.[4][8]

The mandate has sparked significant pushback from state governments. A coalition of 20 state attorneys general recently argued that the rule makes the $5 billion fund unusable, noting that there is not enough immediate demand to justify the massive capital investments required to build 100% domestic supply chains overnight.[1][8]

Despite the hurdles, the mandate is forcing a rapid recalibration within the manufacturing sector. Companies are aggressively scouting U.S. locations for component production, and joint ventures are forming to bridge the gap in domestic electronics manufacturing, though these facilities will take time to come online.[4][6]

While the short-term effect is a severe bottleneck, proponents argue that the growing pains are a necessary step toward true energy independence. If successful, the policy could eventually yield a robust, fully domestic supply chain that secures the future of American transportation infrastructure.[6][8]

The Federal Highway Administration is currently reviewing feedback from state agencies and manufacturers before finalizing the rule. The outcome will determine whether the national charging network accelerates toward completion or remains stalled in a standoff between ambitious industrial policy and supply chain realities.[4][7]
