As the infographic above clearly illustrates, the global tungsten supply chain is one of the most concentrated in the world. Based on 2024 data from the U.S. Geological Survey, a single country—China—dominates the market, accounting for a staggering 83% of all global mine production.

This dominance places tungsten firmly on the critical minerals list for the United States, the EU, and other major economies. But what makes this metal so vital, and what are the implications of a supply chain this lopsided?

Tungsten is not a household name, but it is the hidden backbone of modern industry. Its unique properties make it virtually unsubstitutable in its key applications.

• Extreme Hardness: Tungsten's primary use (over 60%) is in the form of tungsten carbide (WC), a cermet with a hardness approaching that of a diamond. This makes it essential for cutting tools, mining drills, and construction equipment—the very tools used to build our infrastructure and extract other resources.
• Highest Melting Point: At 3,422°C, tungsten has the highest melting point of all metals. This makes it indispensable for high-temperature applications like welding electrodes, rocket engine nozzles, and heating elements in industrial furnaces.
• Extreme Density: With a density similar to gold, tungsten is also used for weights, counterweights, and vibration damping in aerospace and automotive applications.
• Strategic Importance: In defense, tungsten's hardness and density make it a key component in armor-piercing ammunition and other high-performance military hardware.

The 2024 Production Landscape

The 2024 data reveals the extent of this supply concentration. Of the 80,000 metric tons produced globally:

• China was responsible for 67,000 tons (83%).
• Vietnam was a distant second, producing 3,400 tons.
• Russia came in third with 2,000 tons.

The rest of the world's production is fragmented among a handful of smaller players, including Rwanda (1,600 tons), North Korea (1,100 tons), and Bolivia (1,000 tons). Production in Western-aligned nations is minimal, with Australia, Austria, Spain, and Portugal collectively producing just 2,800 tons—only 4% of China's output.

The Geopolitical Equation: Production vs. Reserves

The situation is further complicated when looking at reserves. While production is overwhelmingly concentrated, the tungsten in the ground is slightly more dispersed.

According to the USGS, China holds approximately 2.4 million tons of tungsten reserves, which is about 52% of the global total of 4.6 million tons.

This data reveals a critical insight: China is not just the dominant holder of tungsten; it is the dominant producer by a much wider margin. This strategic position gives it significant leverage over global prices and supply availability.

This dependency has become a major concern for Western governments. The concentration of production, especially for a metal essential to defense and high-tech manufacturing, creates a significant supply chain vulnerability. This is why nations in Europe and North America have made it a priority to "de-risk" by identifying and supporting the development of new tungsten projects outside of China.

However, as the infographic makes clear, closing an 83% production gap is a monumental challenge that will take decades, significant capital, and a fundamental realignment of the global supply chain.
