China’s antimony export ban triggered a 2,600% price spike, signaling potential future curbs on rare earths
Executive summary: China announced export controls on antimony in 2024, driving the metal’s price from roughly $1,400 to $38,000 per ton—a 2,600% increase—and cutting off shipments to the United States. Antimony is a key ingredient in military munitions; the price shock raises costs for defense contractors and signals China’s willingness to use export restrictions on strategic materials.
Who is involved: Chinese government agencies overseeing exports, U.S. defense and industrial buyers, and global antimony miners.
Likely next: Beijing may extend comparable controls to rare earths, prompting Western nations to accelerate stockpiling and seek alternative suppliers.
In 2024 Beijing imposed export controls on antimony, a metal used in over 200 types of munitions, causing its price to leap from about $1,400 to $38,000 per ton. The move disrupted shipments to the United States and highlighted China’s ability to weaponize critical minerals. Analysts warn that similar restrictions could soon be applied to rare earths, which are vital for electronics and defense.
What's next — scenarios
Weaponized Mineral Escalation (50%)
Global defense contractors face sudden, massive cost increases and supply chain decoupling requirements.
- China announces export quotas on Neodymium or Dysprosium
- New restrictions on gallium or germanium implementation
Antimony-Only Isolated Incident (35%)
Commodity volatility remains high but rare earth supply chains stabilize through existing long-term contracts.
- China maintains current antimony quota levels
- Rare earth export license approval rates remain steady
Rare Earth Supply Chain Collapse (15%)
A massive global shift toward non-Chinese permanent magnet producers is forced by emergency government subsidies.
- China bans all unprocessed rare earth ore exports
- U.S. or EU enacts emergency mineral stockpiling mandates
What to watch
- China Ministry of Commerce quarterly export quota announcements (next 60 days)
- LME/Shanghai Metals Market antimony spot price stability (next 30 days)
- U.S. Department of Defense critical minerals procurement updates (next 90 days)
