In September 2023, China announced export restrictions on antimony, with similar measures expected for tungsten in the coming months. These moves, effective as of September 15, 2023, have garnered significant attention from the global minerals industry. Viewed as a strategic maneuver to leverage China's dominance in global supply chains, particularly for metals essential to civilian and military industries, the export restrictions signal a new phase in the ongoing economic and geopolitical competition between China and the United States. This article analyzes China's export data, resource reserves, and the potential impacts on U.S. industries, especially in the defense and high-tech sectors, while examining the competitive dynamics between the two nations in securing these strategic resources.
China’s Dominance in Global Supply of Critical Metals
China holds a commanding position in the global supply chains for critical metals like antimony and tungsten, which are vital for both high-tech and defense applications. The recent export restrictions aim to ensure that these metals remain available for domestic use as China navigates an increasingly complex international environment and geopolitical pressures. With these metals being critical to industries such as semiconductors, energy, and high-end manufacturing, China’s actions could have broad implications for global markets.
Export Data (2018-2023)
Antimony: China accounts for approximately 48% of global antimony production, making it the world’s largest producer. Over the past five years, China has exported an average of 60,000 metric tons of antimony annually, with fluctuations driven by global market demand, price volatility, and domestic policy shifts. Major export destinations include the U.S., Japan, Germany, South Korea, and the Netherlands, where antimony is used primarily in electronics, flame retardants, and battery manufacturing.
Tungsten: China controls about 85% of global tungsten production, positioning itself as the primary source of this critical metal. Between 2018 and 2023, China exported an average of 30,000 metric tons of tungsten annually. However, production has recently declined due to stricter environmental regulations, resource depletion pressures, and rising domestic demand. Major export destinations include Europe (especially Germany and Austria), the U.S., Japan, South Korea, and India, where tungsten is used in cutting tools, electronics, semiconductors, and military equipment.
China’s dominance in these two metals makes it a key player in the global supply chain, but export volumes are subject to various factors such as domestic environmental policies, global market conditions, and strategic national interests. China’s Resource Reserves
China’s vast reserves of critical metals give it significant leverage in global markets.
Antimony: China holds about 55% of the world’s antimony reserves, concentrated in provinces like Hunan, Guangxi, and Yunnan. These reserves enable China to maintain its leading position in the global antimony market.
Tungsten: China controls about 60% of global tungsten reserves, primarily located in Jiangxi, Hunan, and Henan provinces. Despite growing domestic demand, these reserves ensure China’s continued dominance in the global supply of tungsten.
Industrial Applications of Antimony and Tungsten
These metals play a vital role in both civilian and military industries:
Antimony: Antimony is used in the production of bullets, nuclear weapons, and lead-acid batteries, as well as in enhancing the strength and hardness of other metals. It also has significant applications in flame retardants and microelectronics, making it a critical component in several high-tech industries.
Tungsten: Known for its high melting point and hardness, tungsten is widely used in weapons manufacturing, semiconductors, and industrial cutting tools. Its military applications are particularly important, with tungsten being a key material in armor-piercing projectiles and missile components.
Impact on U.S. Industry
China’s export restrictions on critical metals like antimony and tungsten could have severe repercussions for U.S. industries, particularly those dependent on stable and affordable supplies of these materials.
Defense Industry: The U.S. defense sector heavily relies on tungsten for a variety of military applications. A potential shortage could lead to increased costs and production delays, ultimately affecting national security.
High-Tech Sector: The semiconductor industry, which uses tungsten, could experience supply chain disruptions, leading to shortages and higher production costs. This, in turn, could impact the energy sector, particularly in the production of lead-acid batteries and other energy storage solutions.
Manufacturing: U.S. manufacturers that rely on tungsten for cutting tools and industrial machinery could see rising production costs, which may affect their global competitiveness and lead to job losses in certain sectors.
Strategic Competition Between China and the U.S.
The competition between China and the U.S. for control over critical resources is intensifying as both countries recognize the strategic importance of metals like antimony and tungsten.
Strategic Competition: The U.S. has been working to reduce its dependence on Chinese supplies of critical metals, with legislative measures such as the REEShore Act aiming to secure domestic sources of rare earth elements and critical minerals. However, in the short term, the U.S. remains vulnerable to supply disruptions.
Global Supply Chain Dynamics: China’s actions may accelerate efforts by the U.S. and other countries to diversify their sources of critical metals, potentially leading to increased investment in alternative supply chains, including domestic production and recycling programs.
Geopolitical Tensions: These export controls reflect broader geopolitical tensions between China and the U.S. As both nations vie for technological and military supremacy, control over critical resources like antimony and tungsten becomes increasingly crucial.
U.S. Response to China’s Export Restrictions
In response to China’s export restrictions, the U.S. is taking multiple steps to address the critical metals supply issue. Legislative and policy support is being directed toward boosting domestic production and processing of rare earths and critical metals to reduce reliance on China. Measures such as the REEShore Act aim to incentivize domestic mining and processing, while the U.S. also seeks to build supply chain partnerships with resource-rich countries in North America, Australia, and Africa.
By pursuing these strategies, the U.S. hopes to gradually wean itself off dependence on China for critical minerals in the coming years.
Potential Risks for China’s Economy
China’s export restrictions on critical metals could also have unintended negative consequences for its own economy. While these measures give China leverage over global supply chains, they may prompt international customers to seek alternative suppliers, potentially diminishing China’s market share. As global demand for these minerals remains strong, the development of alternative sources could weaken China’s competitive position in the long run. Moreover, restrictions could discourage foreign investment and technology cooperation, further isolating China from the global market and accelerating efforts to diversify away from Chinese suppliers.
China’s export controls on critical metals like antimony and tungsten are a clear signal of its intent to leverage its dominant position in global supply chains to counter rising geopolitical tensions. These measures could exacerbate challenges for U.S. industries, particularly in defense and high-tech sectors. To mitigate these impacts, the U.S. is pursuing a range of measures to secure alternative supplies of critical minerals, both domestically and through international partnerships. However, China’s export restrictions could also backfire, potentially diminishing its market dominance as global competitors ramp up efforts to diversify supply chains and reduce dependence on Chinese resources.
