Trump signed an executive order requiring the US defense supply chain to stop purchasing rare earth, tungsten, molybdenum, and tantalum from China, Russia, Iran, or North Korea by January 1, 2027. The administration has invested billions of dollars to support nearly 150 domestic mineral companies as part of efforts to reduce China's control over US weapon and strategic product supply chains. However, experts warn that US mining and processing capacity remains far from self-sufficient, and exemptions will likely be granted when the deadline arrives. Industry analysts note that building competitive infrastructure will require many more years beyond the current timeline.
US Rare Earth Production Falls Short of Domestic Demand
According to Reuters, defense industry manufacturers and other producers face just over five months until the January 1, 2027 deadline. At that point, companies will be prohibited from purchasing rare earth, magnets, tungsten, molybdenum, and tantalum from China, Russia, Iran, or North Korea under federal regulations.
Data from Arthur D. Little shows that US demand for the most common type of rare earth magnets in 2025 is approximately 48,000 tons, while domestic sources can supply only 300 tons. By the end of this year, US companies are projected to increase production capacity to 5,000 tons.
US companies have not produced tungsten since 2015, and tantalum production ceased in 1959. Guardian Metal Resources plans to open a US tungsten mine by 2028, while Lion Rock Resources is developing a tantalum mine in South Dakota but has not announced an extraction timeline.
Mineral industry analyst and consultant Chris Berry stated that the US industry cannot possibly produce sufficient minerals by January to end current exemption measures. "Building the infrastructure needed to compete will require many more years," Berry said.
Mining Companies Face Extended Development Timelines
Ucore Rare Metals, a mineral refining startup supported by the US Department of Defense, has developed processing technology called RapidSX. The company believes this technology is similar to the industry-standard solvent extraction method but faster, more environmentally friendly, and cheaper.
Ucore originally planned to begin refining operations in 2025, but CEO Pat Ryan told Reuters that due to changing Pentagon requirements, the company has adjusted its plans. Some production will now be delayed until 2027 at the earliest. "Can the entire supply chain be established by 2027? I can only say it's a tough battle," Ryan said.
The US possesses reserves of most critical minerals but lacks the capacity to mine and process many of them. China gradually gained dominance in the global mineral refining industry in the late 20th century and currently controls over 80% of the global market.
The International Energy Agency warned this month that if Beijing imposes restrictions on rare earth exports, global manufacturing industries worth $6.5 trillion will face risks.
White House Tightens Exemption Requirements for Defense Contractors
Washington has attempted to limit such imports for years, but the government has frequently approved corporate exemption applications because domestic supply capacity cannot meet demand.
Trump posted on Truth Social on May 10 criticizing such exemption measures: "All federal agencies must purchase American-made products, no excuses!" He signed an executive order on the 20th to further increase the difficulty for defense contractors to obtain exemption qualifications.
When asked to respond, the White House cited Trump's executive order content, stating that exemptions may only be granted when contractors prove they have "exhausted all efforts" to avoid using Chinese materials and provide a timeline for gradually decoupling from related supply chains. The Pentagon did not respond to requests for comment.
