Tungsten.
The metal behind every drill, every cutting tool, every armour piercing round. The modern world cannot machine itself without it. And almost all of it is refined in one country.
Irreplaceable by physics, not by choice.
China dominates the market, not the geology.
It holds under a third of the world's reserves. Two decades of consolidation policy built the rest. The result is a market with the competitive structure of a monopoly.
Official German statistics show twenty one percent of tungsten imports coming from China. Trace the re exports through the tier one hubs and the true origin dependency is sixty seven percent. That is already past the ceiling the EU Critical Raw Materials Act sets for any single source, sixty five percent.
Ammonium paratungstate. The one node every chain runs through.
APT is the mid stream product from which every downstream value chain is derived. China supplies seventy eight percent of it, at a concentration even higher than the mines. Diversify the mining alone and you have relocated the problem, not removed it.
Seeing the risk is half of it. The other half is the move.
The mitigations, their sequence and their cost are named in the confidential briefing, not on this page. That is the part you act on, and the part we do not publish.
