National Critical Materials Act — Strategic Minerals Policy Framework

The National Critical Materials Act of 1984 establishes federal policy for identifying, assessing, and ensuring adequate domestic and allied supplies of "critical and strategic materials" needed for national defense, clean energy, and advanced manufacturing. The Act created a framework for interagency coordination, federal research investment, and stockpile assessment — but it was the convergence of the EV battery transition, Chinese supply chain dominance, and the Inflation Reduction Act's domestic content requirements that transformed critical minerals from a niche policy concern into a front-line national security priority. Today the 50-mineral USGS Critical Minerals List drives billions of dollars in federal investment and shapes trade policy across the Indo-Pacific.

30 U.S.C. § 1806 — Assessment and inventory: directs USGS to maintain a current inventory of domestic and global critical mineral resources and assess vulnerabilities in supply chains
30 U.S.C. § 1808 — Definitions: defines "critical material" as a material essential to economic or defense applications that faces potential supply disruption

How It Works

The cornerstone of current critical minerals policy is the USGS Critical Minerals List — 50 mineral commodities whose combination of economic essentiality and supply chain vulnerability places them in the highest-priority tier for federal attention. The list includes lithium, cobalt, nickel, graphite (used in battery anodes), all 17 rare earth elements (REEs, used in magnets for EV motors and wind turbines), tungsten, manganese, vanadium, and platinum group metals. USGS updates the list every three years based on production concentration, reserve geography, and substitutability assessments. A mineral's presence on the list triggers eligibility for accelerated permitting review, DOE loan program financing for processing facilities, and DOD Defense Production Act Title III investments.

The supply chain geography of critical minerals is the core policy problem. For rare earth elements, China controls roughly 60% of global mining and 90% of global processing — a dominance built over decades through strategic state investment that deliberately undercut Western producers. For cobalt, more than 70% of global mining occurs in the Democratic Republic of Congo, with the majority of production under Chinese off-take agreements. For graphite, China controls over 90% of global processing capacity. This concentration means that geopolitical tensions, trade disputes, or Chinese export restrictions (China imposed graphite export controls in 2023) can rapidly disrupt supply chains for EVs, wind turbines, defense electronics, and advanced semiconductors.

Federal responses operate on multiple tracks. USGS produces geologic assessments identifying domestic mineral resources. DOE's Loan Programs Office finances domestic mining and processing projects (Lithium Americas' Thacker Pass lithium mine in Nevada received a $2.26 billion DOE loan in 2023). DOD uses Defense Production Act Title III to invest directly in domestic critical mineral production for defense needs. The Inflation Reduction Act created strong financial incentives by restricting the §30D EV tax credit to vehicles whose battery minerals come from the U.S. or from countries with qualifying free-trade agreements — effectively requiring automakers to build non-China supply chains to access the credit. International agreements with Japan, South Korea, and the EU have been used to expand the pool of qualifying "domestic" sourcing under this framework.

How It Affects You

If you're an EV or battery manufacturer needing to qualify for the IRA Section 30D credit: The up-to-$7,500 consumer EV tax credit requires that qualifying critical minerals in the battery be extracted or processed in the U.S. or a free-trade-agreement partner country (and meet increasing percentage thresholds each year). China-sourced lithium, graphite, cobalt, or nickel disqualifies the vehicle. This regulatory structure drives your sourcing decisions — and why Lithium Americas' Thacker Pass (Nevada), ioneer's Rhyolite Ridge, and MP Materials' Mountain Pass matter commercially, not just geopolitically. If your supply chain currently routes through Chinese processors, the IRA mineral tracing requirements and "foreign entity of concern" restrictions are increasingly constraining.

If you're a mining company pursuing a critical mineral project: The Trump administration's January 2025 executive order declaring a national energy and mineral emergency directed federal agencies to accelerate permitting for critical mineral extraction using categorical exclusions from full NEPA environmental review. The Permitting Council's FAST-41 process is being applied to increasing numbers of mine permit applications. DOE's Loan Programs Office (LPO) and DOD's Defense Production Act Title III program have been active investors — the $2.26 billion DOE loan to Lithium Americas for Thacker Pass is the largest single critical minerals investment to date. If your project is on federal lands, engage the Bureau of Land Management's critical minerals program early; expedited processing is available but requires proper initiation.

If you're a technology or defense company with supply chain exposure to Chinese rare earth processors: China controls more than 90% of global graphite processing and imposed export controls on graphite in late 2023, followed by additional gallium and germanium export restrictions. China's dominance in rare earth element (REE) processing means that even if your REE raw materials come from Australia or elsewhere, processed oxides and magnets often route through China. DOD's Title III program has funded several alternative processing projects; check whether your critical inputs qualify for domestic alternatives or FTA-partner sourcing. The USGS Critical Minerals List (updated every 3 years) and the National Defense Stockpile program are the government's formal signals of which materials face the greatest supply risk.

Recent Developments

The Inflation Reduction Act's domestic content requirements for EV battery minerals created an immediate, commercially-significant demand pull for non-Chinese critical mineral supply chains. This triggered billions of dollars in investment announcements for lithium, cobalt, nickel, and graphite projects in the U.S., Canada, and allied countries. Lithium Americas' Thacker Pass project in Nevada — receiving a $2.26 billion DOE loan — and ioneer's Rhyolite Ridge lithium/boron project (also Nevada) represent the vanguard of a domestic lithium mining buildout. MP Materials, which processes rare earth concentrate from Mountain Pass into separated oxides, expanded its magnet manufacturing capacity with DOD support.

The Trump administration entered 2025 with aggressive executive action on critical minerals: an executive order in January 2025 declared a national energy and mineral emergency and directed all agencies to accelerate permits for critical mineral extraction on federal lands, including through categorical exclusions from NEPA review. A separate 2025 executive order directed DOD and Commerce to develop a strategic mineral stockpile plan and expand DPA Title III investments. These actions reflect bipartisan consensus — rare in the current environment — that reducing dependence on Chinese mineral supply chains is a national security imperative. Congressional efforts to further streamline permitting for domestic critical mineral mines remained active in 2025–2026, with the Permitting Council's FAST-41 process being applied to an increasing number of mine permit applications.
