Key findings
What the evidence shows
World production and the largest producer
The USGS puts world production at 81,000 kilograms. Chile is the largest producer with 37% of the total.
How concentrated supply is
The Herfindahl-Hirschman index over country shares is 2,370 (moderately concentrated). The top three producers hold 74%; 2 countries supply half.
United States import reliance
The United States relied on net imports for 75% of its use in 2025; main sources: Chile, Canada, Germany, Poland.

Supply
Who produces it
Below 1,500 is read as unconcentrated and above 2,500 as highly concentrated (US merger-review bands, used as a reference point).
Full analysis and cited sources
Where rhenium is produced
Chile is the largest producer of rhenium, at 37.0 percent of the published world total in 2025[1]. It is followed by China at 24.7 percent, Poland at 12.3 percent and United States at 12.1 percent. The USGS puts world production at 81,000 kilograms; the sum of the country figures is 81,000 kilograms, the difference being rounding in the published total.[1] Reserves are held principally by Chile (1,300,000 kilograms), United States (400,000 kilograms), Russia (310,000 kilograms)[1].
How concentrated supply is
Measured by the Herfindahl-Hirschman index over production shares, rhenium supply is moderately concentrated, with an index of 2,370. The top three producers hold 74.1 percent of output, and 2 producers together account for half of supply. An index below 1,500 is conventionally read as unconcentrated and above 2,500 as highly concentrated; the thresholds are the United States merger-review bands, used here as a published reference point rather than as a judgement about market conduct. The United States was 75 percent reliant on net imports for rhenium in 2025, with the principal import sources over 2021–24 being Chile, Canada, Germany, Poland.[2] The principal sources of United States imports over 2021–24 were Chile (31 percent), Canada (27 percent) and Germany (16 percent)[3].
Trade measures in force
The USGS compilation of export controls effective January 2026 records no measure specific to rhenium. That is a statement about the compiled list, not a guarantee of open trade: measures framed around ores and concentrates generally, or around a broader commodity group, can still apply.
Recent United States official notices
Federal Register documents naming rhenium, most recent first. 2025-11-07: Final 2025 List of Critical Minerals. Critical minerals are essential for national security, economic stability, and supply chain resilience because they underpin key industries, drive technological innovation, and support critical infrastructure vital for a modern American economy. The United States is heavily reliant on imports of certain mineral commodities from foreign sources, some of which are at risk of serious, sustained, and long-term supply chain disruptions.[4]

Executive Briefing & Strategic FAQ
Essential empirical supply-chain and geopolitical questions for market participants and intelligence analysts.
Which countries dominate global mining and refining for Rhenium?▼
Global Rhenium production is characterized by high geographical concentration in both raw extraction and chemical processing, as documented in MiningBridge's empirical supply-chain models.
What are the critical supply chain bottlenecks and geopolitical risks for Rhenium?▼
Key geopolitical and operational risks include export licensing constraints, high chemical conversion barriers, and long lead times for developing non-concentrated commercial refining capacity.
What are the primary commercial uses for Rhenium, and can it be substituted?▼
Rhenium is essential across energy transition, advanced electronics, and defense systems. While direct substitutes exist in select low-performance applications, replacing Rhenium in mission-critical hardware incurs significant metallurgical and cost trade-offs.
