The mechanism: Section 30D's Foreign Entity of Concern rule (26 CFR § 1.30D-6) says a clean vehicle loses its entire $7,500 credit if its battery contains critical minerals or components sourced from a "foreign entity of concern" — in practice, anything traceable to Chinese ownership, control, or licensing. Treasury's 2024 final rule let automakers temporarily exclude "impracticable-to-trace" materials (low-value minerals buried deep in the supply chain) from FEOC scrutiny, but that transition relief runs out at the end of 2026. At the same time, the required critical-minerals and battery-component percentages that must be sourced domestically or from free-trade partners step up — 70% in 2026 rising toward 80% in 2027. The result isn't a demand shock for EVs. It's a supply-chain vise: automakers must lock in contracts with the handful of vendors who can document non-FEOC provenance, and there are only a few of them, so those vendors gain pricing power that has nothing to do with how many EVs actually sell.

Who cashes in:

  • MP Materials (MP) — the only integrated rare-earth miner-to-magnet producer on U.S. soil, running Mountain Pass, California mine-to-metal with a new Fort Worth, Texas magnet facility. It has already landed a Department of Defense price floor (~$110/kg NdPr) and a confidential long-term supply agreement with a major automaker specifically because its neodymium-praseodymium oxide never touches a Chinese entity. That's not an EV-demand trade — it's a "you literally cannot get a 30D-compliant magnet elsewhere" trade.
  • Albemarle (ALB) — its Kings Mountain, North Carolina and Silver Peak, Nevada lithium assets are unambiguously domestic and FEOC-clean, giving it what analysts have called a structural "Western premium" over Chinese lithium converters even in a depressed lithium-price environment. Automakers scrambling to hit the 2026-2027 critical-minerals thresholds need Albemarle's paperwork trail as much as its tonnage.
  • Freeport-McMoRan (FCX) — copper isn't named in FEOC battery rules directly, but EV motors, charging infrastructure, and grid buildout all lean on domestic copper, and Freeport is the largest U.S. producer sitting outside any China-linked ownership structure — a quieter beneficiary of the broader "de-risk the supply chain" mandate.
