China's antimony export controls have created a two-tier market that shows no sign of converging. European antimony metal traded around USD 33,700 per metric ton in July 2026, while China domestic prices sat at roughly USD 15,940 per ton — a gap of more than 50% that reflects the administrative friction and uncertainty embedded in China's export licensing system.
The divergence has been building since China introduced export restrictions on antimony and other strategic minerals. In May 2026, before the most recent correction, Europe antimony was assessed at USD 58,000-59,650 per ton in Rotterdam. The spike was sharp and immediate — a textbook export-control shock. Since then, prices have corrected but remain structurally elevated compared to the pre-control levels around USD 12,000 per ton in 2024.
China's role as the dominant supplier makes this fracture consequential. The country accounts for roughly 55% of global mined antimony and 60-80% of refined output. No other producer comes close. The export licensing system creates months-long delays and bureaucratic hurdles that Western buyers must navigate, effectively rationing supply and pushing Rotterdam prices to a permanent premium.
Demand for antimony is driven primarily by its role as a flame retardant synergist in plastics, electronics, and construction materials — applications where there is no cost-effective substitute at scale. The market is also seeing growing demand from the defense sector, where antimony is used in infrared detectors, tracer ammunition, and other military applications that are inelastic to price. Regulatory pressure on halogenated flame retardants in Europe is creating additional structural demand for antimony trioxide.
Supply outside China is limited. The remaining global production comes from Russia, Tajikistan, and Myanmar — each with its own geopolitical complications. New capacity development in other regions is minimal. The global antimony market is effectively structured around access to Chinese material, and export controls have made that access unpredictable.
The procurement outlook is one of persistent regional divergence and elevated Western pricing. Northeast Asia (including China domestic) averaged around USD 17.4/kg in July, down 12.3% quarter-on-quarter. The Western premium is likely structural rather than cyclical — rooted in a policy decision rather than market fundamentals. Buyers cannot wait this out; they must adapt their supply chains to the new pricing architecture.
Antimony buyers need to accept that the old pricing paradigm is gone. The export control regime is a policy choice, not a temporary disruption, and Western buyers will pay a permanent premium. Strategies should include: building inventory buffers that can absorb licensing delays, qualifying multiple Chinese suppliers to hedge against individual license denials, evaluating antimony trisulfide as a partial substitute in some applications, and engaging directly with the few non-Chinese producers for strategic volumes. The price gap between China domestic and Rotterdam is unlikely to narrow without a policy reversal that is not foreseeable.
