Tungsten Prices Jump 666% as Export Curbs Squeeze Semiconductor and Defense Supply

A Sixfold Price Surge

International tungsten prices have climbed 666% year-on-year, driven by tightening export restrictions from both China and the United States. The metal, prized for its extreme hardness and heat resistance, sits at the heart of advanced manufacturing across semiconductors, aerospace, and defense sectors.

China imposed export controls on tungsten earlier this year, choking off a supply route that has historically fed global manufacturers. The move came as Beijing escalated its grip on strategic minerals, leveraging its dominant position in tungsten production to shape supply chains in its favor.

More recently, the US Department of Commerce announced restrictions on exports of tungsten scrap and battery black mass, materials that can be recycled back into usable tungsten. The regulation adds a second layer of constraint to an already stressed market, limiting the flow of secondary material that manufacturers had relied on to supplement primary ore.

Why Tungsten Matters

Tungsten carbide is a workhorse material in semiconductor fabrication. It serves as a barrier layer in advanced chip architectures and forms the cutting edges of precision tools used to etch and polish silicon wafers. Without reliable tungsten supply, fabs face delays and cost overruns in ramping new process nodes.

Aerospace engineers depend on tungsten alloys for components exposed to extreme temperatures, including turbine blades, rocket nozzles, and guidance systems. The metal's density also makes it indispensable in counterweights and vibration dampers for aircraft.

Defense contractors use tungsten in armor-piercing ammunition, missile components, and shielding for radiation-sensitive electronics. The simultaneous squeeze on primary and secondary supply has prompted procurement teams across the sector to lock in long-term contracts and explore alternative materials, though few substitutes match tungsten's performance envelope.

Regional Reverberations

Asia's semiconductor hubs are feeling the pinch most acutely. Taiwan, South Korea, and Japan import the bulk of their tungsten, either as refined powder from China or as scrap from global recyclers. Foundries in Hsinchu and fabrication lines in Seoul have begun stockpiling inventory, a defensive posture that further tightens spot market availability.

Chinese producers, meanwhile, are redirecting supply to domestic chipmakers and defense contractors, a strategic reallocation that aligns with Beijing's push for technological self-sufficiency. The redirection compounds shortages for offshore buyers who have few alternative sources at scale.

The US restrictions on scrap exports aim to keep secondary tungsten within domestic recycling loops, ensuring American manufacturers retain access to recovered material. But the policy also reduces the volume available to Asian and European recyclers, many of whom had built business models around processing US-origin scrap.

Supply Chain Adjustments

Recyclers are scrambling to secure alternative feedstock. Battery black mass, a byproduct of lithium-ion cell recycling that contains tungsten and other metals, has become a contested commodity. Prices for the material have risen in tandem with tungsten, and processors report longer lead times as buyers compete for limited volumes.

Mining companies with tungsten assets outside China are accelerating exploration and development. Projects in Vietnam, Rwanda, and Canada are attracting fresh investment, though new capacity will take years to come online. In the interim, manufacturers are rationing tungsten use, redesigning parts to minimize material content, and in some cases delaying product launches.

Some fabrication equipment makers are testing tungsten-rhenium and tungsten-molybdenum alloys to stretch available supply, though these blends introduce trade-offs in thermal stability and machinability. The adjustments underscore the urgency with which industrial buyers are seeking to navigate a market reshaped by geopolitical friction.

What Comes Next

Market participants expect prices to remain elevated through the remainder of the year. Analysts note that even if export restrictions ease, restocking demand and limited spare capacity will keep upward pressure on quotes. The prospect of further trade measures, either from Beijing or Washington, adds a layer of uncertainty that is likely to sustain volatility.

For semiconductor fabs and aerospace manufacturers, the tungsten crunch is a reminder of the fragility embedded in specialized material supply chains. As the US and China continue to wield export controls as strategic tools, industries dependent on narrow sourcing bases will face recurring episodes of price spikes and allocation battles.
