IRA Supply Chain Rules

The IRA's clean vehicle tax credit ($7,500) comes with strings: the battery must contain critical minerals sourced from US or free-trade-agreement countries (50% in 2024, rising to 80% by 2027), and battery components must be manufactured or assembled in North America (60% in 2024, rising to 100% by 2029). If either requirement is not met, the credit is halved. These rules transform a climate incentive into an industrial policy instrument.

The China exclusion. Starting in 2024, any vehicle with battery components from a "foreign entity of concern" (primarily China and Russia) is disqualified from the credit entirely. Since China produces 75% of the world's lithium-ion battery cells and processes 60-90% of critical minerals, this effectively requires automakers to rebuild their entire battery supply chain.

The compliance challenge. In early 2024, fewer than 25 EV models qualified for the full $7,500 credit. Tesla, which sources batteries from multiple countries, qualified some models. Hyundai, which assembles batteries in South Korea, qualified for half. Many Chinese-battery-dependent models qualified for nothing. Automakers announced $100+ billion in US battery factory investments to comply.

Do supply chain requirements slow EV adoption by limiting eligible vehicles?

In the short term, yes. Fewer qualifying models means fewer consumers receive the full credit, slowing adoption. In the medium term, the factories being built to comply will create domestic supply chains that reduce Chinese leverage. The policy accepts slower near-term deployment as the cost of building resilient long-term supply chains, a tradeoff between climate speed and industrial security.
