Iran War Drains Tungsten Supply; China Controls 80% of Global Output
Tungsten scarcity forces a choice between sustaining current Iran war tempo and maintaining industrial base capacity for peer-conflict scenarios. If China restricts exports or the blockade extends into Q3, the DoD will face either production rationing (which limits strike packages) or price spikes that consume FY27 procurement dollars meant for new platform development.
This converts a supply-chain story into a force-readiness variable.
This is a real constraint, not theoretical.
The Pentagon spent $25B on ordnance alone in the first eight weeks of the Iran war — and tungsten-heavy kinetic munitions (DU rounds, penetrators) make up a significant portion of that burn rate. If sustained demand exceeds US strategic reserves and allied stockpiles, procurement will compete directly with commercial aerospace and semiconductor applications.
Raytheon, L3Harris, and General Dynamics all depend on reliable tungsten feedstock; a supply crunch forces either price escalation (margin compression on fixed-price contracts) or allocation conflicts between munitions production and commercial backlog. The China dependency is the real problem.
Beijing has no incentive to increase exports, and can credibly threaten supply restrictions if US-China tensions escalate further. Unlike semiconductors, there is no alternative material for armor-piercing warheads.
Does the Pentagon have formal guidance on tungsten allocation priority between munitions production and commercial defense contractors? If not, who arbitrates when supply tightens?
