Antimony prices soared to an unprecedented $59,750 per tonne in July 2025, igniting a global scramble as supply shortages deepened. The ensuing volatility has reshaped market dynamics, catching miners, manufacturers, and governments off guard.
Key Takeaways
- Antimony prices peaked at $59,750 per tonne in July 2025 before easing to approximately $39,500 by mid-2026.
- China controls over 70% of global antimony production and imposed export bans affecting U.S. supply since December 2024.
- Perpetua Resources’ Stibnite Gold Project aims to fill 35% of U.S. antimony demand by late 2028 amid ongoing supply gaps.
- U.S. Defense Logistics Agency increased stockpile efforts in early 2026 due to military-grade material scarcity.
What Triggered the Antimony Price Surge and Supply Crisis?
Antimony prices hit record levels after China restricted exports in late 2024, significantly curtailing global supply. Beijing’s ban on shipments to the United States, citing national security, doubled prices from $10 to over $20 per pound within months. By July 2025, the Rotterdam spot price peaked at $59,750 per tonne, forcing industries to find costly alternatives or cut back usage. These restrictions exposed the risks of a supply chain heavily reliant on one country.
Currently, prices have corrected downward but remain about 35% below the 2025 highs, stabilizing near $39,500 per tonne by June 2026. China’s partial lifting of export bans for civilian-grade antimony extended through November 2026 has eased some pressure. However, military-grade antimony remains tightly controlled, maintaining supply tension for defense sectors reliant on the metal.
How Is the Defense Sector Responding to Antimony Price Volatility?
The U.S. defense industry consumes roughly 40% of antimony supply, primarily for ammunition and infrared sensor production. The 2024–2025 shortage prompted the Defense Logistics Agency to expand metal stockpiles aggressively in early 2026. Despite these efforts, limited availability of military-grade antimony caused a more fragmented market between civilian and defense uses. Analysts emphasize growing concerns over availability risk, not just pricing, highlighting the metal’s strategic importance.
Efforts to diversify sourcing and increase stockpiles are ongoing amid ongoing export restrictions. This situation underlines the critical intersection between antimony market dynamics and national security policy, pushing defense procurement to rethink supply resilience.

What Pressures Is the Industrial Sector Facing Due to Rising Antimony Costs?
Industrial demand, especially from the flame retardant sector, accounts for nearly half of U.S. antimony consumption. Manufacturers use antimony trioxide to meet strict fire safety regulations across plastics, textiles, and electronics. The metal’s price surge has placed intense cost pressure on polymer producers, with no direct effective substitutes available. Additionally, solar energy applications in China compete for antimony supplies, reducing export volumes for Western industries.
Refining and processing plants now face urgent needs to improve efficiency amid high raw material expenses. These industrial challenges demonstrate how elevated antimony prices ripple beyond mining into downstream manufacturing, emphasizing the metal’s critical role.

Can Western Projects Bridge the Antimony Supply Gap?
Western supply expansion remains the key to reducing reliance on China. The Stibnite Gold Project in Idaho, managed by Perpetua Resources, stands as the most advanced U.S. initiative to boost domestic antimony output. The project cleared crucial permits by early 2025 and started construction after securing $139 million in financial assurance. It also attracted nearly $80 million in U.S. Department of Defense funding and seeks a $2 billion Export-Import Bank loan.
Despite progress, Stibnite’s first antimony production is not expected until late 2028. Upon startup, it should meet about 35% of annual U.S. consumption, still leaving substantial shortfalls. Until then, the supply gap persists, forcing reliance on recycling and imports from countries including Tajikistan and Vietnam.

Industry Impact: What This Means for Antimony Mining and Supply Chains
The antimony price surge underscores vulnerabilities in the global mining sector’s supply concentration. China’s dominance over 70% of production exposes supply chains to geopolitical risk, causing major price shocks that ripple through industrial and defense sectors. Companies like Perpetua Resources highlight Western efforts to mitigate risk by developing domestic sources, although lengthy project timelines maintain pressure on markets.
Mining investors and operators must consider enhanced risks tied to export policies and capacity constraints. Strategic reserves, such as those of the U.S. Defense Logistics Agency, now form central pillars of commodity security.

Market Analysis: How Antimony Prices Are Shaping Investment and Supply Strategies
Antimony prices peaked near $60,000 per tonne in mid-2025 before stabilizing between $38,000 and $40,000 by mid-2026. This elevated price level well exceeds pre-pandemic averages around $5,800 per tonne in 2020. Supply restrictions and escalating demand, especially in defense and industrial applications, have created a market with sustained tightness and higher costs.
As China’s export policies remain fluid, secondary recycling plays an increasing though insufficient role in cushioning supply. Southeast Asian smelting expansion also provides some relief. The price volatility has prompted renewed investor interest in antimony projects, particularly those that can boost Western supply. For market details, consult the mining finance reports and historic price tables.
Future Outlook: What Investors Should Watch in the Antimony Market
Investors should focus on the expiration of China’s civilian export suspension in November 2026. A reinstatement of the ban could trigger another price spike and panic buying. Meanwhile, domestic projects like Stibnite Gold will remain watchpoints as their production timelines will shape supply dynamics through 2028 and beyond.
Increasing secondary recycling and Southeast Asian processing capacity may marginally alleviate shortages but not replace primary supply. Market participants must prepare for continued volatility and potential supply disruptions while anticipating Western project ramp-ups. Ongoing coverage is available through mining news channels.
In summary, antimony prices hit record highs in 2025 due to supply shocks primarily caused by China’s export bans, sending prices to unprecedented levels. The situation has shifted investment and procurement toward domestic production and strategic stockpiling, signaling a new era for the metal’s market. Careful attention to policy changes and project milestones will be key for investors navigating this tight supply landscape.
