Tungsten vs. Other Critical Minerals: Why Supply Risk Is Different
China accounts for roughly 80% of global tungsten mine production and around 85% of ammonium paratungstate (APT) processing, a concentration higher than most other critical minerals. Export controls and tariff actions in 2025 pushed tungsten prices sharply higher, underscoring why buyers are prioritizing diversified, traceable sources such as South America.
How Concentrated Is Tungsten Supply, Really?
Tungsten's supply chain is unusually concentrated at both the mining and processing stages. China supplies close to 80% of mined tungsten and an even higher share, near 85%, of APT, the standard intermediate product most manufacturers actually purchase. That double concentration, at both the raw material and the processed-material stage, is part of what sets tungsten apart from many other critical minerals.
In 2025, this concentration translated into real market volatility. Following new export controls from China and increased U.S. tariffs on Chinese tungsten products, benchmark prices for tungsten concentrate and APT roughly doubled within the year. For buyers with contracts tied to a single region of origin, that kind of swing is a direct cost and planning risk.

Comparing Tungsten to Other Critical Minerals
Most critical minerals carry some degree of geographic concentration, but the pattern differs by material:
| Mineral | Primary Supply Concentration | Key Risk Factor |
|---|---|---|
| Tungsten | ~80% mining, ~85% APT processing (China) | Concentrated at both mining and processing stages |
| Rare Earth Elements | Majority mining and most processing (China) | Processing concentration even more extreme than mining |
| Cobalt | Majority mining (Democratic Republic of Congo) | Single-country geological concentration, governance risk |
| Lithium | Split across Australia, Chile, China processing | Mining more diversified; processing still China-heavy |
| Copper | More geographically diversified globally | Newer critical-mineral designation; demand-driven risk |
The pattern that stands out: tungsten and rare earths share the trait of concentrated processing, not just concentrated mining. A buyer can theoretically source ore from a non-Chinese mine and still end up dependent on Chinese processing capacity to turn that ore into a usable intermediate product. This is why supply chain diversification for tungsten has to account for processing capacity, not only where the rock came out of the ground.
Why Diversified Sourcing, Like South America, Matters
South American supply is not a future possibility, it is already a meaningful part of the U.S. tungsten import mix. Bolivia was tied for the third-largest source of U.S. tungsten ore and concentrate imports from 2021 to 2024, accounting for about 8%, on par with Vietnam and behind only China (26%) and Germany (14%). For buyers looking to reduce China-concentrated exposure, established South American supply chains, including Bolivia, offer a track record most emerging projects elsewhere have yet to build.
New tungsten supply is starting to emerge outside China, including projects in South Korea, the United Kingdom, Canada, and Kazakhstan, but much of this capacity is still under development and subject to execution risk and uncertain timelines. South American sources, including established concentrate supply chains, offer buyers a way to diversify today rather than wait for new projects to reach commercial production.
Diversification also intersects directly with regulatory compliance. U.S. defense procurement rules are set to restrict sourcing tungsten metal powder and heavy alloys from China and other designated countries starting in 2027, and broader FEOC-related rules already affect eligibility for various federal incentive programs. A supplier relationship built around verified, non-Chinese origin addresses both the price-volatility risk and the compliance risk at the same time.
What This Means for Buyers Today
- Tungsten's risk profile is shaped by concentration at both the mining and processing stages, not mining alone
- Price volatility in 2025 showed how quickly concentrated supply can affect cost and availability
- New non-Chinese supply is emerging but remains early-stage and execution-dependent
- Diversified, traceable sourcing addresses both cost risk and regulatory compliance requirements simultaneously
