A July 2026 Government Accountability Office assessment confirms that the United States is building critical-minerals processing capacity faster than it is securing the raw material to run it. Battery scrap is still being landfilled or shipped abroad, semiconductor recycling remains years away from viability, and the gap between capital commitments and operational infrastructure is widening as a January 2027 defense procurement deadline approaches. The findings point to a midstream-specific structural problem that billions in federal investment alone cannot fix.
Introduction
Imagine spending billions of dollars building a network of flour mills, only to discover that the wheat supply chain remains broken. The mills are real, the investment is real, but the shelves stay empty. That is roughly the situation the Government Accountability Office described in a report released on July 22, 2026, covering America's push to build domestic critical-minerals processing capacity.
The report, GAO-26-108687, was submitted to the House Committee on Energy and Commerce and focused on 11 minerals used in batteries and semiconductors, including cobalt, lithium, nickel, copper, gallium, and manganese. Its central finding was blunt: building processing plants does not guarantee that those facilities will have enough material to process. The United States is investing heavily to reduce its dependence on foreign supply chains, but the feedstock those new plants need is still being landfilled, exported, or lost to overseas processors.
This matters to manufacturers, defense contractors, policymakers, and anyone who uses a battery or a smartphone, which is to say nearly everyone. As of December 2025, the U.S. Geological Survey reported that 12 critical minerals had a net import reliance of 100 percent, and 34 more exceeded a significant import-dependence threshold. The GAO report lands at a moment when federal commitments to fix that problem have never been larger, yet the structural gap between investment and operational readiness has rarely been wider.
What the GAO Report Actually Says
The GAO's analysis covered technologies that could reduce import reliance through two pathways: substitution (replacing a scarce mineral with a different material) and recycling (recovering minerals from waste streams like old batteries, electronics, and manufacturing scrap). Its conclusions were sharply different depending on which industry and which technology you look at.
For batteries, the news is cautiously encouraging on technology but discouraging on infrastructure. Battery recycling technologies are mature. The process of recovering lithium, cobalt, nickel, and copper through chemical leaching and smelting is well understood. Experts told the GAO that established recycling methods could reduce imports of those four minerals within two to three years. The problem is not the science; it is the plumbing. The United States does not have the infrastructure needed to collect large quantities of batteries at scale and process them domestically. Instead, most of that recycling happens abroad.
The substitution side of the battery story is similarly mixed. Lithium iron phosphate, or LFP, batteries could reduce imports of cobalt, manganese, and nickel for stationary grid storage in the near term. But LFP batteries carry a performance penalty in high-demand applications like long-haul electric vehicles, where their lower energy density is a real constraint. Lithium-free battery chemistries that might eliminate the problem entirely are not yet commercially mature.
For semiconductors, the picture is considerably bleaker. Gallium, indium, and germanium, minerals where China controls dominant shares of global supply, do not yet have substitute materials that perform equivalently. Experts told the GAO that industry will not adopt substitutes until they match current materials in performance. Technologies to recycle minerals from semiconductor manufacturing scrap and end-of-life chips face an underdeveloped market and are not yet standard practice in the United States. The GAO's assessment is that building effective semiconductor recycling infrastructure could make recycled material the primary source of these minerals within ten years, and that meaningful substitutes are at least a decade away. That timeline offers no relief for the supply pressures arriving in 2027.
The Midstream Problem: Why This Is Not Just About Mining
To understand why the feedstock gap is so significant, it helps to think about where in the supply chain the real bottleneck sits. The value chain for critical minerals runs roughly from mining (pulling ore out of the ground) through midstream processing (refining that ore into battery-grade chemicals or semiconductor-quality compounds) and on to downstream manufacturing (turning those compounds into batteries, magnets, chips, or defense components). Most of the public attention and most of the political rhetoric focuses on the mining end. But as I covered in my earlier piece on the IEA's 2026 Outlook, the critical vulnerability sits in the middle: refining and processing.
The GAO report reinforces that point from a different angle. The United States has built collection and shredding capacity for battery scrap faster than it has built the downstream hydrometallurgical refining capacity needed to recover the actual minerals from that shredded material. The result is a substance called black mass: shredded lithium-ion battery scrap containing cathode materials, including lithium, cobalt, nickel, and manganese. It is, in effect, a domestic above-ground resource. But before mid-2026, limited domestic refining infrastructure meant most black mass processors had few commercial options beyond exporting the material.
This is a chicken-and-egg problem with serious economic consequences. A domestic refiner cannot justify the capital cost of a new facility when the feedstock keeps leaving the country. A black mass collector has no reason to invest in sorting and storage when there is no local buyer who can process it. Meanwhile, manufacturing scrap, end-of-life electronics, and retired rare-earth magnets, all materials that domestic processors need, are being landfilled or shipped abroad. The GAO found weak data and analytical tools for deciding which recovery technologies and infrastructure investments to prioritize, which makes planning harder still.
The report's scope also has a notable limitation. Its 11-mineral focus excludes rare-earth magnets, a gap that leaves a significant portion of the supply chain unaddressed at precisely the moment when domestic magnet manufacturing is being assembled in Texas and California.
Policy Responses: Export Controls, Executive Orders, and Federal Investment
The federal government has responded to the feedstock problem with a combination of investment, export controls, and executive action, some of it arriving in the weeks after the GAO report's release.
On July 30, 2026, President Trump issued a determination under the Defense Production Act authorizing the commerce secretary to establish export controls on recoverable critical minerals, explicitly including black mass, end-of-life rare-earth magnets, tungsten scrap, and other waste streams containing critical materials. The Bureau of Industry and Security followed on August 6 with a Temporary Final Rule requiring U.S. persons selling covered black mass to allocate 100 percent of monthly sales to other U.S. persons. That rule took effect August 27, 2026, and expires after one year on August 27, 2027. Then, on August 26, President Trump signed Executive Order 14420 banning imports of foreign battery energy storage systems, signaling that additional executive actions targeting battery materials are likely.
The intent of the black mass export restriction is straightforward: guarantee domestic refiners a feedstock supply so they can justify building U.S.-based processing plants. Industry reactions have been mixed. Several domestic recycling companies voiced support, citing the benefit of a more consistent feedstock supply to spur investment. Others raised concerns about supply chain disruption, permitting alignment with existing environmental laws, and whether domestic refining capacity can absorb the sudden influx of material previously processed overseas.
On the investment side, the numbers are substantial. The U.S. government has mobilized more than $30 billion in letters of interest, loans, investments, and other support for critical minerals projects over the past six months. Aggregate federal commitments across Department of Energy channels exceed $2 billion in announced funding, including a $500 million Battery and Processing notice of funding opportunity, a $475 million DOE loan to Glencore Battery Recycling, and a $150 million Critical Material Innovation funding opportunity. Pentagon financing under the Defense Production Act has accelerated from roughly $540 million in July 2025 to nearly $4.9 billion in conditional loan agreements by August 2026. Federal equity investment in minerals companies has reached $8.6 billion since January 2025.
The GAO itself identified four policy options for closing the gap: establishing domestic manufacturing capacity to produce substitute technologies; building domestic recycling infrastructure; securing inputs for recycling through collection, sorting, transportation, and storage programs; and funding research and development. National e-scrap collection programs, combined with financial incentives for collection and storage, could meaningfully expand the feedstock pool, though the report acknowledged that battery storage safety issues and insufficient commercial demand remain obstacles.
What the Objections Look Like
There are legitimate competing perspectives on how to read the GAO's findings and the policy responses they have prompted.
Supporters of the current approach argue that the sequencing problem is real but solvable, and that the export controls on black mass are exactly the intervention needed to break the chicken-and-egg dynamic. By guaranteeing domestic refiners a feedstock supply, the argument goes, the government creates the commercial certainty that justifies plant construction. The $475 million DOE loan to Glencore Battery Recycling and the broader $500 million Battery and Processing program are designed to fund precisely that missing midstream infrastructure. From this view, the GAO report is a useful diagnostic, but the policy response is already in motion.
Critics offer several counterarguments. First, the one-year expiration on the black mass export rule creates its own uncertainty. Refiners considering major capital investments need long-term feedstock security, not a twelve-month guarantee. Second, the economics of black mass recycling are genuinely difficult. Analysis suggests that black mass alone can represent roughly 48 percent of modeled hydrometallurgical recycling costs, and the rise of lower-value lithium iron phosphate batteries makes those economics tougher still, since LFP chemistry yields less recoverable cobalt and nickel per tonne of scrap. Third, the GAO itself flagged that weak data and analytical tools make it hard to prioritize which recovery technologies and infrastructure to fund, raising the risk that investment flows toward politically visible projects rather than structurally important ones.
A broader critique comes from the National Mining Association, whose president Rich Nolan responded to the report by noting how hard it is to put a dent in China's decades-long strategy to dominate minerals markets. That framing points to a structural asymmetry: capital costs for refining projects outside the dominant supplier are 20 to more than 150 percent higher than inside it, according to the IEA's 2026 Outlook, and operating costs are on average around 50 percent higher. Building a competitive domestic midstream is not simply a matter of writing checks.
What Happens Next
Several near-term developments will shape how this story unfolds over the coming months.
The most immediate pressure point is January 1, 2027, when statutory prohibitions take effect on purchasing defense materials from foreign adversaries. S&P Global Market Intelligence data from July 2026 puts the average U.S. mine discovery-to-production timeline at nearly 30 years, meaning no mining project currently in development will contribute meaningful supply before that deadline. The gap has to be closed by recycling, stockpiling, or allied-nation sourcing, none of which is moving as fast as the deadline requires.
The Department of Energy's $500 million Battery and Processing program is due to announce its seven selected projects later in 2026. Those selections will signal which technologies and facility types the government has decided to back, and how seriously the feedstock-first logic of the GAO report has penetrated procurement decisions. The BIS rule's one-year clock is also running. If domestic refining capacity does not expand materially before August 2027, the government will face a choice between extending the export restriction (which may provoke trade friction) or allowing black mass to flow abroad again.
Building on my earlier analysis of how America's new processing plants may run short of raw material, the GAO report confirms that the feedstock problem is not a footnote to the capacity buildout story; it is the central structural challenge. The White House's 2026 National Security Science Strategy identifies critical mineral vulnerabilities, but analysts have noted it lacks a concrete midstream industrial plan with specific capacity targets for 2027, 2030, and 2035. Proposals for a National Critical Minerals Midstream Mobilization Plan, mapping every strategic bottleneck from concentrate through finished component and using Defense Production Act financing to bridge projects until commercial markets mature, are circulating in policy circles but have not yet translated into legislation.
The United States is, in summary, building the mills. Whether it will secure the wheat in time is a question that investment alone cannot answer.
