The U.S. needs more of this obscure metal — and China owns 80% of its supply chain

China’s dominance in the supply chain for critical minerals is well-known, but the country has not implemented sweeping restrictions on tungsten, a valuable material used in various industries. Tungsten is important for its hardness and high energy density, making it useful in weapons, automobiles, electric car batteries, semiconductors, and industrial cutting machines. Despite the Biden administration’s recent tariffs on tungsten imports, China did not include the metal in new regulations aimed at boosting oversight of rare earths production. Experts believe China is not concerned about these tariffs and wants to avoid escalating tensions. Efforts to diversify away from China in the tungsten market are growing, with the US and Europe seeking alternative sources. Demand for non-Chinese tungsten is increasing, leading to rising prices. China currently dominates over 80% of the tungsten supply chain. However, other countries such as South Korea are becoming players in the market. Projects to produce tungsten outside of China have faced challenges and delays, but there is potential for growth.
