The U.S. Treasury proposed guidance last Friday that would significantly restrict what battery parts and materials can qualify for incentives in the Inflation Reduction Act. The rules label China and several other countries as “foreign entities of concern.” These rules will prevent materials and parts sourced from those countries, starting in the next few years, from counting toward the IRA’s electric vehicle tax credits. The new rules are meant to push battery companies to develop supply chains outside the control of Chinese officials and companies, which control much of the world’s battery industry. They come following a first batch of guidance released this year by the Treasury, which the IRA tasked with developing specific rules for implementing the law. So what does the new guidance mean for battery supply chains? This episode features two conversations with Sam Jaffe, senior director of business development at Addionics. The first is a short update on last week’s proposed rules. The second is a longer conversation Shayle had with Sam in April about the first batch of rules, which focused on which battery ingredients count as “constituent materials” under the IRA. Both discussions are relevant to understanding what’s happening now. In this update they cover topics like: Defining what counts as a material controlled by a foreign entity of concern, such as percentage ownership in a joint venture Key loopholes in law, such as licensing arrangements and small percentages of low-value materials, like cathode binder and electrolyte salts  The parts of the supply chain most significantly affected by the rule, such as Chinese graphite, Indonesian nickel, and Congolese cobalt Upcoming deadlines in 2025 and 2026, and whether onshored or friend-shored facilities can begin supplying materials before then Recommended Resources: Canary: The US EV industry now faces a choice: Tax credits or Chinese batteries Heatmap: It’s Suddenly a Mystery Which EVs Will Qualify for a Tax Credit in 2024 Sign up for Latitude Media’s Frontier Forum on January 31, featuring Crux CEO Alfred Johnson, who will break down the budding market for clean energy tax credits.
