Tungsten Supply Gap Persists Through 2030?S&P Data Reveals a Deeper Feedstock Squeeze

Highlights

• S&P Global projects only ~34,000 tonnes WO₃ of ex-China mine capacity by 2030 against ~50,000 tonnes of primary demand, leaving a 16,000-tonne gap.
• APT CIF prices surged from $83/kg in January to $340/kg in July 2026, yet economics are no longer the main constraint—execution is.
• Ex-China APT refining capacity could reach 70,000 tonnes WO₃ by 2030 while mine supply lags, creating a fierce competition for limited concentrate and scrap.
• Recycling supplies roughly 60% of ex-China tungsten output, and long-term offtake deals like Sangdong's 21-year contract with GTP further tighten available spot feedstock.
• China controls ~79% of tungsten mining and ~85% of APT refining, yet imports ~30% of the concentrate feeding its own refineries—signaling a global feedstock squeeze.

S&P Global's August 2026 tungsten analysis (opens in a new tab) points to a problem more complicated than China's dominance. Even if 11 announced ex-China mines arrive, S&P projects only ~34,000 tonnes WO₃ of mine capacity by 2030 against roughly 50,000 tonnes of ex-China primary demand after recycling—a 16,000-tonne gap. Yet the deeper REEx finding is upstream: refiners are multiplying faster than secure feedstock.

REEx Insight | The Real Shortage Is Becoming Mobile Feedstock

China still controls roughly 79% of tungsten mining capacity and 85% of ammonium paratungstate (APT) refining capacity. But buried beneath those familiar numbers is the more consequential trend: China imports roughly 30% of the concentrate feeding its own refining system, while its mining share has declined about six percentage points since 2016.

Meanwhile, ex-China APT capacity could rise from roughly 42,000 tonnes WO₃ today to 70,000 tonnes by 2030, while mine capacity reaches only about 34,000 tonnes. Western refiners, Chinese processors, and defense-compliant supply chains could increasingly chase the same limited pool of concentrate and high-quality scrap. That is the emerging choke point.

Rare Earth Exchanges® tracks rare earths and the broader critical-minerals complex, because these supply chains increasingly rhyme: mining concentration, processing bottlenecks, geopolitical controls, and the race for qualified, traceable material.

Price Is Screaming—Supply Still Cannot Move Fast Enough

APT CIF surged from about $83/kg WO₃ in January to $340/kg in July 2026. Yet S&P calculates that only $36–48/kg would structurally support more than 85% of identified current and proposed ex-China projects. Even $90/kg could theoretically support the entire modeled pipeline.

That extraordinary spread exposes the real problem: economics are no longer the principal constraint. Execution is.

Financing, permitting, construction, commissioning, qualification, and feedstock security take years. Another ~20,000 tonnes of announced mine capacity is already stalled by economic or permitting challenges and excluded from S&P's main supply case.

The Market Is Smaller Than It Looks

Recycling already supplies roughly 60% of ex-China tungsten output, making quality scrap strategically important. And new mine output can disappear into long-term contracts: 90% of Sangdong Phase I production is committed to Global Tungsten & Powders for 21 years. The investment takeaway is stark: the premium may increasingly migrate from owning nominal processing capacity to controlling secure, traceable feedstock.
