Critical Mineral Dominance Act
Current understanding
The Critical Mineral Dominance Act directs the Department of the Interior to accelerate hardrock and critical mineral production on federal lands, including identifying and expediting priority mining projects, rescinding agency actions deemed burdensome to domestic mineral development, and quantifying the economic costs of U.S. reliance on imported mineral commodities. The bill is framed as a supply-side response to import dependence rather than a tariff or export-control measure, and would primarily affect domestic miners, downstream manufacturers using critical minerals, and importers currently sourcing from foreign suppliers. Status: introduced.
Evidence log
- 2026-08-04 — Presidential Determination Pursuant to Section 101 of the Defense Production Act of 1950, as Amended, on Recoverable Critical Minerals and Materials: cross-connection with dpa-section-101-recoverable-critical-minerals: The Critical Mineral Dominance Act pursues by statute the same domestic supply-security objective that the Section 101 determination advances through executive DPA authority. (novelty: 3)
- 2026-07-23 — Securing America’s Defense Supply Chains and Ensuring Domestic Acquisition of Critical Materials: cross-connection with defense-supply-chain-critical-materials-eo: Legislative and executive-branch tracks pursuing the same domestic critical-minerals dominance objective for defense supply chains. (novelty: 3)
- 2026-07-16 — Critical Materials Processing Technology Testbed Act: cross-connection with critical-materials-processing-testbed: Both aim to strengthen domestic critical minerals/materials capacity as a hedge against import reliance; the testbed focuses on downstream processing technology while the Dominance Act addresses broader supply-chain policy. (novelty: 3)
- 2026-07-14 — Quantum-Enhanced Critical Minerals Mapping Act of 2026: cross-connection with critical-minerals-mapping-quantum: Complementary strategies: dominance-act focuses on production/processing policy while HR9646 targets the resource-identification stage of the same supply chain. (novelty: 3)
- 2026-02-05 — Critical Mineral Dominance Act: cross-connection with critical-mineral-import-reliance: The Act operationalizes the import-reliance concern by mandating accelerated domestic hardrock production and formal quantification of import-dependence costs. (novelty: 3)
