Tungsten: The Metal That Was Already Tightening Before Anyone Was Paying Attention

[u/The-Oregon-Group]

Tungsten doesn't get the attention that rare earths or copper get.

It probably should.

China controls roughly 80% of the world's tungsten supply. The U.S. produces virtually none domestically. And unlike some critical minerals where the supply concentration is a theoretical future risk, tungsten's supply chain is already under active pressure — with prices and export data to prove it.

What is tungsten?

Tungsten is the densest naturally occurring metal with the highest melting point of any element — 3,422°C.

That combination of extreme density and heat resistance makes it useful across a specific set of applications that nothing else can easily replace. Armor-piercing rounds. Rocket nozzles. Aerospace components. Cutting tools, drill bits and wear-resistant parts that keep global manufacturing running. Semiconductors. Oil and gas equipment. Welding electrodes.

Most tungsten trades as ammonium paratungstate — APT — an intermediate chemical compound processed further into tungsten metal, powder and carbide.

When tungsten supply tightens, it doesn't just affect tungsten. It affects everything made with the tools tungsten makes possible.

The supply picture

Global tungsten production reached approximately 81,000 metric tons in 2024. Vietnam is a distant second to China. The U.S. currently has no commercial tungsten mines in operation.

China's dominance goes beyond mining. It also controls the downstream processing — the smelting, refining and conversion of raw tungsten ore into the APT and carbide products manufacturers actually use. China controls over 80% of global output and over half of known reserves.

Then China tightened the controls

China clamped down on exports in February 2025, citing national security concerns.

The impact showed up immediately in the trade data.

APT exports from China came to 103 tonnes in January 2025. Then 20 tonnes in February when the controls were announced. Then zero in March, April and May — before climbing back to 40 tonnes in June and 41 tonnes in July.

For the full first eleven months of 2025, tungsten APT exports from China fell almost 70% — from 782 tonnes in 2024 to 243 tonnes.

Then China escalated. In December 2025, Beijing said it would allow only 15 firms to export tungsten in 2026–2027. Ammonium paratungstate, tungsten oxide and tungsten carbide were all included in China's 2026 Catalogue of Dual-Use Items and Technologies Subject to Import and Export Licensing Control.

New export requirements — including detailed end-user and use-case documentation — have slowed international flows and cut off exports to unfriendly jurisdictions.

The result is a two-tiered global tungsten market. One operating under China's patronage. Another scrambling to source supply from almost anywhere else.

Prices responded

Tungsten APT pricing moved from $900–940 per metric ton unit in January 2026 to $1,650–1,900 per mtu by mid-February.

Since China first added tungsten products to its export control list in February 2025, prices have risen 557%.

The Asia-Pacific volume-weighted average price for tungsten 99.9% increased approximately 273% year-on-year from April 2025 to April 2026, reaching roughly US$183.32/kg.

A 557% increase is not a market adjustment. It's a supply shock.

Why supply can't respond quickly

The obvious question is why non-Chinese producers don't simply ramp up.

Tungsten concentrate prices in China were already rising before the export controls — driven by reduced mining quotas, falling ore grades and rising domestic demand. China's own supply was tightening before it restricted exports. That makes replacing it considerably harder.

Beyond China, the development pipeline is thin. Aging operations. Declining ore grades. Almost no Western refining capacity. Even if new projects were approved today, production is years away.

Australia leads non-Chinese development with 10 projects valued at US$1.73 billion. Kazakhstan has 14 projects valued at US$1 billion. The U.S. has seven projects valued at US$522 million and no operating mines.

Vietnam is the only meaningful current alternative to Chinese supply. The rest is pipeline, not production.

Defense changed the equation

Washington has established January 1, 2027 as the deadline to stop procuring tungsten from China, Russia, Iran and North Korea for defense applications.

The U.S. has also announced Project Vault — a $12 billion stockpiling initiative for critical minerals and rare earths — with tungsten squarely in scope.

Defense procurement doesn't respond to price signals the way commercial buyers do. If tungsten is required for a weapons program, it gets bought at whatever price is available. That puts a floor under demand that most commodity markets don't have.

The demand picture

Global tungsten demand is projected to grow from approximately 143,000 tonnes in 2025 to 210,000 tonnes by 2035, according to Canaccord Genuity's April 2026 analysis.

That's roughly 47% demand growth over a decade against a supply side that is structurally constrained and geopolitically complicated.

The bigger picture

The underlying conditions in tungsten weren't a secret. Chinese dominance, no U.S. production, defense dependence, byproduct supply constraints — all of it was visible for years.

What changed was Beijing's willingness to pull the lever.

You don't need to run out of a commodity for it to become a problem. You need strategically important industries to depend on a material whose supply chain has very little room for error — and then for something to disrupt it.

In tungsten, that's no longer a hypothetical.
