Focus: Antimony
Class: Tier 1 Urgency — Defense, Grid Hardening, Flame Retardants

⛓️ What’s Happening

China now controls over 84% of the world’s antimony supply — and recent reports suggest delays at ports and pricing pressure are tightening the global pipeline. Antimony is crucial for military-grade alloys, grid-scale battery storage, and flame-retardant systems.

Meanwhile, the U.S. Defense Logistics Agency (DLA) added antimony to its high-priority stockpile list, and Perpetua Resources is advancing the only near-term U.S. source.

🔍 Strategic Takeaways

  • Antimony is a choke point in the U.S. defense and energy security chain.

  • Grid-scale batteries (esp. liquid metal batteries) rely heavily on stable antimony sourcing.

  • China’s internal demand for antimony is rising, likely reducing export availability further.
