Iran War Exposes Critical US Tungsten Dependency on China for Weapons Production

The Iran war has driven tungsten prices up over 500% as US munition consumption rapidly depletes stocks of the metal essential to armor-piercing rounds and precision weapons. China dominates global tungsten production and imposed export controls in late 2025. Foreign Policy reports it will take years before the US can build a supply chain that does not touch China. DOD restrictions on Chinese-sourced tungsten for defense contracts take effect January 2027, but current wartime consumption outpaces any alternative supply.

Analysis
The 500% price surge exposes a strategic vulnerability the Pentagon has known about but not resolved. DOD restrictions on Chinese-sourced tungsten do not take effect until January 2027, meaning the current war is being fought with munitions whose supply chain runs through the very country providing weapons to the adversary. This is the clearest example of how the Iran war has turned a latent supply chain risk into an acute operational constraint.
