Trump’s 2027 Ban on Chinese Critical Minerals Set to Miss Deadline as U.S. Processing Lags

A Deadline the U.S. Minerals Industry Can’t Meet

A January 1, 2027 federal deadline that would bar the U.S. defence industry from buying Chinese rare earths, tungsten, tantalum and other strategic minerals is likely to be missed by a wide margin, according to interviews with 16 industry executives, investors and analysts. The gap between ambition and reality is stark. In 2025, demand for the most common rare earth magnet was 48,000 metric tons; U.S. companies supplied just 300 metric tons. American firms have not produced tungsten since 2015 and tantalum since 1959.

President Trump has made ending reliance on Chinese minerals a national security priority, pouring tens of billions of dollars into nearly 150 minerals companies and signing an executive order last Monday that makes it harder for defence contractors to obtain waivers. Yet the industry data and project timelines make clear that no amount of funding can compress the processing build-out into the next five months. Even the most advanced Pentagon-backed startups, such as MP Materials and Energy Fuels, will not have meaningful magnet or rare earth output until 2028 at the earliest.

The administration itself is hedging. In February it launched Project Vault, a $12 billion stockpiling effort that officials acknowledge will initially need to buy minerals “from anywhere in the world,” including China. Meanwhile, defence prime Lockheed Martin has handed the Pentagon a list of minerals it wants stockpiled rather than placing orders with new U.S. producers, a posture that frustrates domestic startups who say without binding contracts they cannot scale.

Why American Processing Projects Are Still Years Away from Commercial Scale

Pentagon-Funded Startups Are Racing the Clock

The funding spigot is open—Ucore Rare Metals, Phoenix Tailings, ReElement Technologies and Energy Fuels have all received Pentagon loans or investments—but processing technologies are still being calibrated. Ucore’s RapidSX solvent extraction alternative, described as faster and cleaner, won’t begin some production until 2027 at the earliest. ReElement’s chromatography process, borrowed from pharmaceuticals, has never been used at industrial mineral volumes. MP Materials spent years just calibrating its solvent extraction equipment, a “painstaking” process that delayed its Texas magnet plant, which now targets a first customer approval by year-end.

Why Waivers Are Almost Certain to Continue

The executive order signed on 21 July 2026 demands an “exhaustive effort” to avoid Chinese material, but with domestic supply meeting less than 1% of magnet demand, that standard is impossible for most contractors. Price suppression by Chinese state-backed producers further erodes the commercial case for U.S. projects. Industry analyst Chris Berry says it will take “many more years” to build the needed infrastructure. The inevitable result is that waivers will persist well beyond 2027, risking a cycle where contractors assume they can keep buying Chinese products and domestic players never get the offtake agreements they need.

The Price Problem and China’s Dominance

China controls more than 80% of global minerals refining, a position built over decades. Washington blames Beijing for subsidising production and flooding the market with cheap material, making U.S. projects unprofitable. The International Energy Agency recently warned that $6.5 trillion of global manufacturing is at risk if Beijing imposes export restrictions—a threat that makes the U.S. supply gap a systemic vulnerability, not just a defence procurement headache.

From Stockpile to Long-Term Supply

Project Vault’s $12 billion stockpile is a pragmatic stopgap, but it also creates a tension: if defence contractors can draw from a government stockpile filled with Chinese-sourced minerals, the incentive to order from U.S. producers is blunted. Partnerships with allies such as South Korea and Japan may provide a bridge, but ultimately domestic processing capacity must scale. The companies that succeed will be those that can lock in commercial offtake agreements alongside military contracts—a step most defence primes have so far been unwilling to take.

What Defence Contractors and Policymakers Should Do Now

For Defence Primes and Investors

• Begin binding offtake agreements now. The executive order requires an “exhaustive effort” to avoid Chinese supply; startups such as Phoenix Tailings and MP Materials can provide that evidence only if defence contractors commit to multi-year orders. Waiting risks both wafer-eligibility and future supply.
• Plan for a extended waiver regime. With domestic capacity for rare earth magnets at 5,000 tons by year-end versus 48,000 tons of demand, a hard cut-off on 1 January 2027 is impossible. Primes should model for waivers through at least 2029 while building parallel supply chains.
• Use Project Vault strategically. The $12 billion stockpile can ease immediate shortages, but the Pentagon should mandate that a rising share of stockpiled material be sourced from domestic producers once they are operational, mirroring the “buy American” mandate Trump has touted.
• Watch the China risk closely. The IEA’s $6.5 trillion exposure warning is not theoretical. Investors in U.S. minerals startups face a binary outcome: if Beijing restricts exports, even small-scale domestic production becomes a premium asset; if cheap Chinese supply continues to flow, projects will struggle to reach profitability without sustained government price supports.
