US DOMINANCE Act on critical minerals: supply chain takeaways for engineers

30 Second Briefing
The US House has passed H.R. 7037, the DOMINANCE (Developing Overseas Mineral Investments and New Allied Networks for Critical Energies) Act, aimed at cutting reliance on China, which currently controls about 90% of global rare earth processing capacity. The legislation focuses on overseas strategic mineral investments with allies, expanded energy diplomacy, and workforce development to support mining, processing, refining, and recycling. Backers include the National Association of Manufacturers, the Information Technology Industry Council, SAFE’s Center for Critical Minerals Strategy, and the US-ASEAN Business Council.
Technical Brief
- DOMINANCE is framed as bipartisan energy-security legislation, co-sponsored by Representatives Ami Bera and Young Kim, both from California.
- Scope covers the full value chain: mining, processing, refining and recycling of critical minerals for energy systems.
- Energy diplomacy tools are to be aligned with economic instruments to steer overseas strategic mineral investments.
- Workforce development funding is aimed at building technical expertise for secure, diversified critical mineral supply chains.
- Critical minerals are positioned as foundational to the US defence industrial base and advanced manufacturing sectors.
- Beijing’s prior use of export restrictions and economic coercion is cited as justification for supply-chain diversification.
- Support spans national security, manufacturing, technology and climate policy groups, including Third Way and Climate Leadership Council.
Our Take
China’s roughly 90% share of rare earth processing cited in H.R. 7037 lines up with other coverage in our database showing Beijing also tightening export controls on rare earths, which suggests the DOMINANCE Act is being framed in Washington as a direct response to emerging resource nationalism rather than a generic industrial policy move.
