Highlights

• The U.S. Defense Logistics Agency is investing $1 billion to secure strategic minerals and reduce dependence on China's supply chains.
• Key minerals include:
  • Cobalt
  • Antimony
  • Tantalum
  • Scandium
• These minerals are critical for defense technologies and national security.
• The stockpile aims to provide short-term supply resilience.
• However, it does not fully close the strategic mineral gap with China's extensive reserves.

The Pentagon—via the Defense Logistics Agency (opens in a new tab) (DLA)—is fast-tracking up to $1 billion in strategic minerals to blunt China’s leverage over U.S. defense supply chains. The surge follows Beijing’s new export curbs on rare earths/related tech and Washington’s tariff threats. Multiple independent reports and company releases confirm the buys and the speed-up. Rare Earth Exchanges (REEx) reports on the National Defense Stockpile (NDS).

What’s being bought (and why)

Mineral	Summary
Cobalt	Up to $500 million (~7,500 metric tons over ~5 years). First U.S. cobalt stockpile since 1990 to support jet-engine super-alloys and defense magnets. Tender restricted to non-Chinese suppliers (e.g., Canada, Japan, Norway). Analysts estimate this equals roughly one-sixth of non-China alloy-grade output—tightening Western supply but boosting U.S. leverage.
Antimony	About $245 million (~3,000 metric tons over 5 years). Sole-source contract with U.S. Antimony Corp (USAC); first $10 million order issued, deliveries starting late 2025. Characterized as sufficient for national-emergency industrial mobilization—vital for munitions and electronics. 2024 U.S. use ≈ 24,000 t → this stockpile ≈ 12–15 % of annual demand
Tantalum	Around $100 million for high-purity metal used in capacitors and jet-engine alloys. With negligible domestic mine output, supply will likely come from imports or recycling via approved U.S. or allied processors. Source: Mining.com.
Scandium	About $45 million (~6 t Sc₂O₃) sourced from Rio Tinto (Canada) and APL Engineered Materials (U.S.). Used in Al-Sc aerospace alloys; deal reportedly priced above market expectations, reflecting strategic urgency over cost
Signals on indium/bismuth	Pentagon RFPs include ~222 metric tons of indium—close to U.S. annual use—indicating intent to build surge buffers, not mere top-ups. Quantities for bismuth not yet disclosed.

Timeline: ready by late-2026 to early-2027?

Likely yes for core metals. The One Big Beautiful Bill (OBBA, informal name) sets $7.5B for critical minerals, including $2B to expand the National Defense Stockpile (NDS) by 2027; today’s $1B spree is effectively phase one. DLA issued multiple tenders by mid-2025 and is using multi-year IDIQs to pull deliveries forward. Antimony is already ramping; scandium can deliver quickly; cobalt awards run to 2030 but should yield meaningful tonnage by 2027.

Friction to watch: Excluding Chinese/DRC/Indonesian cobalt narrows supply; brokers say hitting 7,500 metric tons without paying up is “challenging.” Funding is secure and urgency high—trajectory still favors the late-2026/2027 goal. Source: The Oregon Group.

Is $1B enough? No—the investment will be useful but limited.

Factor	Summary
Scale	GAO (2024) pegs DoD critical-material shortfalls at ~$18.5B—about 18× this tranche and 80× recent annual stockpile budgets
Scope	This round covers a few top-risk inputs (cobalt, antimony, tantalum, scandium). Other chokepoints—rare earth magnets, graphite, nickel, titanium, specialty semiconductors—are mostly outside this tranche (though OBBA’s broader B supply-chain fund and a $500M credit program help).
Duration	The NDS is designed for weeks-to-months bridging in crises, not years. An Atlantic Council stress test finds public/private stockpiles deplete quickly in severe disruptions; stockpiles smooth supply—they don’t create it.

Net: The $1B hardens the tip of the spear—keeping munitions and aero alloys flowing through an initial shock—while broader U.S. industry (EVs, electronics) remains exposed without parallel civilian buffers.

The China yardstick (where the gap remains)

• Production/processing dominance: ~70% rare-earth oxide mining; ~85–90% rare-earth processing; ~80% cobalt refining; leading antimony miner.
• Deep state reserves: Prior reports cite ~2 Mt copper, 900 kt aluminum, 350 kt zinc (2021); reportedly 7,000+ metric tons cobalt and ~40,000 metric tons rare earths relevant to defense—far beyond current U.S. holdings. Beijing has used reserve releases to steady domestic markets.

The Bottom Line

The U.S. move narrows immediate risk for key defense lines and adds bargaining power—but it doesn’t erase China’s multi-decade head start.

• Readiness: On track for substantial delivery by 2026–27; contracts funded and moving.
• Sufficiency: Necessary but insufficient. Good for shock absorption, not prolonged decoupling.
• What’s next (America-forward): Keep buying the most weapon-critical inputs and accelerate non-China capacity—mine, refine, recycle, substitute. Expand the NDS beyond today’s metals; coordinate with allies’ reserves; use the Defense Production Act where strategic and cost-effective. That critical mineral and rare earth element industrial policy remains a cornerstone of the critical mineral and rare earth policy REEx has consistently emphasized.

If Washington sustains this pace—and couples stockpiles with real Western supply—U.S. leverage grows and Beijing’s coercive power shrinks. The $1B is the right first step. It shouldn’t be the last.
