National Defense Stockpile — Strategic Materials Reserve

The National Defense Stockpile (50 U.S.C. §§ 98–98h) is a federal reserve of strategic and critical materials — minerals, metals, and other raw materials that are essential for national defense and that the United States would need in a national emergency but cannot produce domestically in sufficient quantities. Managed by the Defense Logistics Agency's Strategic Materials division, the stockpile was created in 1939 as World War II loomed and the U.S. faced potential cutoffs of critical imports. At its Cold War peak, the stockpile held over $10 billion worth of materials including tin, tungsten, cobalt, chromium, manganese, rubber, and dozens of other commodities. Since the end of the Cold War, the stockpile has been significantly drawn down — Congress has authorized the sale of surplus materials, using the proceeds to fund other defense programs. Today's stockpile is valued at approximately $1 billion and focuses on materials critical to modern defense technology: rare earth elements, titanium, cobalt, lithium, beryllium, and other specialty materials essential for advanced weapons systems, electronics, and aerospace.

Current Law (2026)

Legal Authority

• 50 U.S.C. § 98f — Special Presidential disposal authority (President may order disposal of stockpile materials in a national emergency declared by Congress)
• 50 U.S.C. § 98h — National Defense Stockpile Transaction Fund (revolving fund — proceeds from stockpile sales are deposited and available for new acquisitions)

How It Works

The stockpile holds materials determined strategic and critical — essential for military, industrial, and civilian use in a national emergency but not available domestically in sufficient quantities to meet emergency demand. Historical holdings included tin, natural rubber, chromium, cobalt, manganese, tungsten, and industrial diamonds. Today's focus is on materials critical to advanced technology: rare earth elements (essential for precision-guided munitions, fighter jet engines, and military electronics), titanium (aircraft structures), cobalt (jet engines, batteries), beryllium (satellite systems), germanium (fiber optics, infrared systems), and lithium (batteries). Each year, DOD submits an Annual Materials Plan (AMP) to Congress identifying which materials to acquire, which to dispose of, and the financial impact — based on DOD modeling of materials needed to sustain a major-war scenario lasting a defined period. Congress must authorize major disposals; proceeds from sales go into the Transaction Fund for future acquisitions.

The stockpile's history shows a troubling cycle: built up during the Cold War to guard against prolonged conventional war cutting off overseas mineral access, then systematically drawn down after the Cold War when Congress used over $7 billion in surplus sales to fund other defense programs — treating the stockpile as a piggy bank. That drawdown left the U.S. with minimal strategic reserves at exactly the moment China's dominance emerged as a national security concern. China now controls approximately 60% of rare earth mining and 90% of rare earth processing — materials essential for virtually all advanced weapons systems. The 2022 NDAA authorized multiyear procurement contracts for domestically processed critical minerals under § 98e-2, and the Defense Production Act has been invoked to support domestic mining and processing, but rebuilding takes years and faces constraints: limited domestic capacity, environmental permitting timelines, and competition with commercial demand for the same materials.

How It Affects You

If you're a defense industry manufacturer or prime contractor: The stockpile is both a supply source and a price signal. When DLA Strategic Materials acquires materials — rare earths, cobalt, beryllium, titanium sponge — it tightens an already thin market and can push prices higher. When it disposes, it adds supply and can depress prices. Monitor the Annual Materials Plan (AMP), which DOD submits to Congress each year — it tells you what the government intends to buy and sell over the next 12 months. The AMP is available through the DLA Strategic Materials website at dla.mil/strategic-materials.

If you manufacture advanced weapons systems, precision-guided munitions, jet engines, satellite components, or military electronics, understand your exposure to the 16 rare earth elements, cobalt, and beryllium — DLA Strategic Materials tracks these specifically. China controls approximately 90% of global rare earth processing, meaning your supply chain for samarium, neodymium, dysprosium, and other magnet-grade rare earths runs through a single geopolitical chokepoint. The stockpile provides a buffer, but current inventory doesn't cover even a 6-month conflict scenario for many materials.

You can also purchase materials directly from the stockpile — DLA conducts sales of surplus materials through competitive solicitations. Register at sam.gov and search for DLA Strategic Materials solicitations. These purchases can be priced below spot market for legacy materials the government has declared excess.

If you're a domestic mining or mineral processing company: The stockpile's expanded acquisition authority is a direct revenue opportunity — but accessing it requires navigating federal procurement.

The multiyear procurement authority under 50 U.S.C. § 98e-2 — enacted in the 2022 NDAA — allows DLA to sign long-term contracts (up to 10 years) for domestically processed critical minerals. This is specifically designed to de-risk investment in domestic processing capacity, which requires enormous capital and takes years to build. If you're building or expanding a rare earth separation facility, lithium refinery, cobalt processing operation, or similar facility, a DLA multiyear contract can anchor your business case for investors and lenders.

To pursue stockpile contracts: monitor sam.gov for DLA Strategic Materials solicitations, review the current USGS Critical Minerals List (50 minerals as of 2025) to confirm your materials qualify, and contact DLA Strategic Materials directly at dla.mil/strategic-materials/programs for market research and industry day information. The Defense Production Act Title III program — administered by Air Force Research Laboratory — complements the stockpile by funding domestic industrial capacity; check the Air Force Title III program for parallel funding opportunities.

Important: stockpile acquisitions require domestic processing — raw ore from a foreign mine processed overseas does not qualify. The "domestic content" requirement is strict and enforced.

If you're a military planner or defense acquisition professional: The stockpile's usefulness in a near-peer conflict depends on two things: whether the right materials are on hand and whether the wartime industrial base can actually use them. Current DOD war-gaming suggests the stockpile covers only a fraction of requirements for an extended high-intensity conflict — particularly for neodymium-iron-boron magnets (used in motors, actuators, and guidance systems), cobalt superalloys (jet engine turbine blades), and germanium (infrared optics and fiber optics). The 2022 and 2023 NDAAs authorized DLA to begin rebuilding these reserves, but physical rebuilding takes years.

The Annual Materials Plan is your primary tool for understanding gaps between stockpile levels and DOD's assessed wartime requirements. If your acquisition portfolio has critical materials not appearing in the AMP, engage DLA Strategic Materials directly — the AMP is shaped by requirement inputs from the military services.

If you're a critical minerals investor or analyst: The National Defense Stockpile is one of three interlocking federal mechanisms supporting domestic critical mineral supply chains — alongside Defense Production Act Title III (industrial capacity investment) and IRA/CHIPS Act tax credits (domestic manufacturing incentives). Together, these mechanisms represent the federal government's multi-billion-dollar bet on reducing dependence on Chinese-dominated supply chains.

What to watch:

• DLA sam.gov solicitations for stockpile acquisitions signal which materials face the most acute supply gaps. Recent acquisitions have focused on rare earth oxides, cobalt metal, and beryllium products.
• China export controls: Beijing's restrictions on gallium (2023), germanium (2023), and graphite (2023-2024) exports — materials where China holds dominant global market share — directly elevated the strategic importance of the stockpile for those materials and created price spikes visible in London Metal Exchange data.
• NDAA annual provisions: Each year's NDAA includes stockpile-related provisions. The 2024 NDAA expanded DLA's authority to enter strategic partnerships with allied nations' material reserves — watch for bilateral stockpile agreements with Australia (nickel, cobalt, lithium), Canada (cobalt, uranium), and Japan (rare earth recycling).
• Publicly traded companies with significant exposure to stockpile acquisition demand include MP Materials (Mountain Pass rare earths mine and processing, NYSE: MP), Albemarle (lithium, NYSE: ALB), Materion (beryllium, NYSE: MTRN), and Compass Minerals (specialty minerals, NYSE: CMP). DLA acquisition announcements can move these stocks.

State Variations

The National Defense Stockpile is exclusively federal:

• State economic development agencies may support domestic mining and mineral processing that feeds the stockpile
• State environmental permitting affects the timeline for developing domestic mineral sources — see Federal Mining Law for the federal framework governing mineral extraction
• State mineral rights laws govern private mining operations that may supply the stockpile

Recent Developments

The strategic competition with China has elevated stockpile policy from an obscure defense logistics topic to a national security priority. The 2022 and 2023 NDAAs significantly expanded stockpile authorities, including the multiyear procurement authority for critical minerals. DLA Strategic Materials has begun acquiring rare earth elements, lithium, cobalt, and other materials identified as critical. The Executive Order on America's Supply Chains (2021) directed a comprehensive review of critical mineral supply chains, reinforcing the stockpile's role. The Inflation Reduction Act and CHIPS and Science Act include billions in incentives for domestic critical mineral processing — complementing stockpile acquisitions with industrial base development. Despite these efforts, rebuilding the stockpile to meet modern requirements will take years given limited domestic production capacity.

• Trump critical minerals executive order — accelerated domestic production and stockpile emphasis (2025): President Trump signed an executive order in March 2025 declaring a national energy emergency and directing accelerated development of domestic critical mineral resources, including streamlined permitting for mines that supply stockpile materials. The order invoked the Defense Production Act to support domestic rare earth, lithium, cobalt, and uranium production. For the stockpile specifically, the order directed DOD to identify and prioritize acquisition of materials with the most acute Chinese supply chain dependence — particularly neodymium-iron-boron magnets, heavy rare earths like dysprosium and terbium, and germanium (used in infrared optics and fiber optics).
• China escalates critical mineral export controls — gallium, germanium, graphite restricted (2023–2025): China imposed export licensing controls on gallium and germanium in August 2023 (effective immediately), and expanded restrictions to include graphite in December 2023. By 2025, China has extended controls to additional antimony, bismuth, and specialty alloys. These controls directly affect materials in the National Defense Stockpile or targeted for acquisition — China controls approximately 80% of global gallium production and 60% of germanium. DLA Strategic Materials has accelerated acquisition of stockpile-relevant materials affected by Chinese controls; the 145% tariff rate Trump imposed on Chinese goods in 2025 further complicated supply chain economics for processors relying on Chinese raw material inputs.
• 2025 NDAA stockpile provisions: The FY2025 National Defense Authorization Act included provisions to expand the National Defense Stockpile Transaction Fund's acquisition authority, authorize bilateral stockpile agreements with Australian and Canadian critical mineral producers, and direct the DOD to conduct a 90-day assessment of stockpile adequacy for a Taiwan Strait conflict scenario. The assessment findings (classified) were provided to Congress; unclassified summaries confirm significant shortfalls in rare earth magnets and specialty metals required for munitions and advanced electronics production at wartime rates.
• DOGE DLA workforce reductions — stockpile administration affected (2025): DOGE-driven workforce reductions at the Defense Logistics Agency have included early retirement offers and hiring freezes affecting DLA Strategic Materials staff. While stockpile physical assets are not at risk, the administrative capacity to execute complex multiyear procurement contracts, conduct competitive solicitations for new acquisitions, and manage disposal proceedings has been reduced. Processing timelines for new stockpile acquisition contracts have lengthened; industry partners reporting delays in contract awards for DLA solicitations published in FY2024.
