Congress Introduces Critical Minerals Innovation Partnership Act: Washington's Supply Chain Strategy Continues to Expand Beyond Mining

Highlights

• Representative Young Kim introduced H.R. 9858 to establish a Critical Minerals Innovation Partnership focused on international cooperation and allied supply chain development.
• REEx warns that faster permitting and stronger alliances alone won't eliminate U.S. strategic dependence without commercial-scale separation, metallization, and magnet manufacturing.
• China continues to dominate the highest-value midstream segments of the rare earth supply chain, including alloy production and permanent magnet manufacturing.
• Allied producers like MP Materials, USA Rare Earth, and Lynas Rare Earths are expanding capacity, but most projects won't reach full commercial scale until 2027 or later.
• Congress is simultaneously advancing domestic permitting reform, Earth MRI reauthorization, and next-generation exploration technologies as part of a comprehensive minerals strategy.

Rare Earth Exchanges® (REEx) today highlights the introduction of H.R. 9858, the Critical Minerals Innovation Partnership Act, (opens in a new tab) legislation introduced by Representative Young Kim (R-CA-40) (opens in a new tab) that would establish a Critical Minerals Innovation Partnership. Introduced on July 22, the bill has been referred to the House Foreign Affairs Committee.

Representative Young Kim, (R-CA)

Although legislative text has not yet been released, the bill's title, sponsorship, and committee referral indicate that Congress continues to expand its critical minerals agenda beyond domestic mining toward international cooperation, innovation, and allied supply chain development.

"This legislation is another signal that Washington increasingly recognizes critical minerals as a geopolitical and industrial systems challenge rather than simply a mining issue. The policy conversation has evolved from permitting mines to building resilient mine-to-magnet ecosystems with trusted allies.

The proposal follows a series of congressional and executive actions aimed at reducing U.S. dependence on China across critical mineral supply chains. Representative Kim has also championed the bipartisan DOMINANCE Act, legislation designed to strengthen partnerships with allied nations by aligning U.S. diplomatic, development finance, and investment tools to support critical mineral supply chains abroad.

H.R. 9858 also arrives as Congress considers complementary legislation to accelerate domestic mineral permitting, reauthorize the Earth MRI geologic mapping program, and advance next-generation exploration technologies such as quantum sensing. Collectively, these initiatives reflect a broader shift toward integrating resource development, permitting, mapping, financing, diplomacy, and international partnerships into a comprehensive critical minerals strategy.

The Midstream Challenge Remains

Rare Earth Exchanges cautions that expanding mining and international partnerships addresses only part of the strategic challenge. China continues to dominate the highest-value segments of the rare earth supply chain, including separation, metallization, alloy production, and permanent magnet manufacturing. These midstream capabilities—not mineral deposits themselves—remain the principal source of Beijing's leverage over global supply chains.

According to REEx Chief Business Officer and Co-Founder John Parkinson, the United States has made remarkable progress in recognizing the problem." Parkinson, an Australian national, further elaborated: "The next challenge is ensuring that policy translates into commercial-scale separation, metallization, alloy production, and magnet manufacturing. Without those capabilities, faster permitting and stronger alliances alone will not eliminate strategic dependence."

Recent investments by MP Materials, USA Rare Earth, Lynas Rare Earths, Carester, and Less Common Metals demonstrate that allied industrial capacity continues to expand. However, many of these projects are not expected to achieve full commercial scale until 2027 or later, while procurement requirements and geopolitical pressures continue to intensify.

Rare Earth Exchanges' Assessment

The introduction of H.R. 9858 is another indication that Congress increasingly views critical minerals through the lens of national security, industrial competitiveness, and strategic alliances rather than as conventional commodity markets.

For investors, the principal question is no longer whether additional mines will be developed, but whether the United States and its allies can not only expedite permitting and other bureaucracy but also rapidly build the industrial middle of the supply chain. The most important metrics to monitor, in addition to accessing heavy rare earth feedstock, remain progress in separation, metals, alloys, magnet manufacturing, and traceable supply-chain infrastructure—the capabilities that ultimately determine whether Western supply chains can compete independently of China.
