Supply structure: mine production by country
China is the largest producer of cadmium, at 41.0 percent of the published world total in 2025[1]. It is followed by Republic of Korea at 18.6 percent, Canada at 5.6 percent and Japan at 5.6 percent. The USGS puts world production at 23,000 metric tons; the sum of the country figures is 23,160 metric tons, the difference being rounding in the published total.[1]

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 Cadmium?▼
Global Cadmium 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 Cadmium?▼
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 Cadmium, and can it be substituted?▼
Cadmium is essential across energy transition, advanced electronics, and defense systems. While direct substitutes exist in select low-performance applications, replacing Cadmium in mission-critical hardware incurs significant metallurgical and cost trade-offs.
