RE:U.S. and Japan Cooperate on Critical Metals The key statement in the article that is relevant to Sokoman is this:
The catch, however, is that there is a “Made in the U.S.” provision for such projects and that includes EVs and the minerals that make up their batteries. In order for a carmaker to qualify for a federal $7,500 EV credit, it must be able to provide evidence that at least half of the metals and minerals used in the car’s battery were sourced from the United States itself or a country with which the U.S. has a free trade agreement.
