This two-page official commodity sheet is one of the clearest annual snapshots of cobalt supply. It combines domestic production, trade, recycling, prices, world output and reserves in a format that exposes where industrial dependence actually sits.
The sheet should be read as a balance sheet rather than a forecast. Its value is the consistency of definitions across years and countries, while our analysis focuses on the difference between geological availability, usable production and qualified industrial supply.
What the official report establishes
USGS records the structure of the U.S. cobalt industry, principal uses, trade flows, recycling and import sources. It also identifies events and policy changes that affected the market during 2025.
The world-production and reserves table provides a common official baseline. Estimates can later be revised, but the sheet makes concentration, trade dependence and the scale of domestic capacity immediately visible.
Production, trade and market numbers
Congo (Kinshasa) supplied an estimated 230,000 tonnes in 2025 and about 73% of global mined cobalt; Indonesia supplied about 44,000 tonnes and 14%. U.S. mine output was only about 300 tonnes, with import reliance near 79%.
The figures are most useful when compared across stages. Mine production, refining, semi-fabrication and final consumption are not interchangeable; a country can be a significant miner while remaining dependent on imported refined material or components.
Supply-chain and industrial consequences
The market combines extreme mine concentration with dominant Chinese refining. Export quotas in Congo demonstrate that policy decisions can move availability and inventories more rapidly than mine development.
For procurement and policy, the correct response is stage-specific. New mining does not solve a shortage in refining, qualified chemicals, alloying, recycling or component production. Inventory and substitution strategies must use the same material specification as the threatened application.
Where the real bottlenecks sit
Cobalt risk sits across mine ownership, intermediate products, refining and battery-chemical qualification. Much cobalt is produced as a by-product of copper or nickel, so supply does not respond only to the cobalt price. Hydroxide, matte, metal and sulfate are not interchangeable. The chain is further concentrated because a large share of mined material is converted in a small number of refining jurisdictions.
Demand, substitution and qualification
Battery chemistry is changing, but cobalt remains important in selected high-energy cathodes, superalloys, hard metals and catalysts. Substitution in one market can alter price and investment signals for another. A procurement strategy should distinguish between declining cobalt intensity per battery and growth in total battery output, while protecting non-battery users that cannot easily change alloy systems.
Pollution, circularity and social licence
The social and environmental burden cannot be separated from security of supply. Traceability, labour conditions, tailings, acid use and energy sources affect whether material is acceptable to regulated buyers. Excluding high-risk production without creating alternative qualified capacity can, however, tighten the market and displace problems rather than solve them. Due diligence must be paired with investment in credible supply routes.
A practical supply-chain stress test
The highest-impact scenario is not necessarily mine depletion; it is a policy or logistics interruption affecting intermediate exports or refining. Because the market is concentrated, quotas, royalties, stockpiling or port constraints can alter availability quickly. Buyers should map contractual rights, inventory location and conversion capacity rather than relying on annual mine totals.
Decision framework for industrial users
The official figures should be converted into a company-specific exposure model for cobalt. Start with annual consumption by grade and form, identify every qualified supplier and conversion step, then calculate usable inventory after allowing for in-process material, minimum order quantities and transport time. This exposes the difference between apparent stock and material that can actually enter production.
Next, separate structural and temporary responses. Structural responses include new capacity, redesign, recycling systems and supplier qualification; temporary responses include inventory, toll conversion, route changes and demand prioritisation. Treating a temporary price fall as proof of long-term security is as dangerous as treating a short spike as evidence of permanent scarcity.
Finally, assign indicators and decision thresholds. Official annual data provide the baseline, but operating decisions need higher-frequency signals such as plant outages, freight, exchange inventories, premia, treatment or conversion charges, policy announcements and customer qualification status. The objective is not to predict one price; it is to know which action becomes necessary under each state of the chain.
Limits, uncertainties and omissions
USGS values are annual estimates and can mask monthly volatility, company-level outages and quality differences. Reserve figures are not a direct measure of commercially available supply, and production numbers do not show the full environmental or social cost of extraction.
Implications for governments, producers and investors
- Maintain a stage-by-stage cobalt flow map from mine to end use.
- Compare import reliance with recycling potential and domestic conversion capacity.
- Use official tonnage with grade, form and qualification requirements.
- Update the annual baseline with higher-frequency market and company data.
What to watch next
- Revisions to production and reserve estimates.
- Changes in export controls, tariffs or stockpile policy.
- New refining, recycling and substitution capacity entering qualified production.
