How a $2.5B Deal Targets America’s Tungsten Chokepoint

The United States sourced tungsten from a single dominant supplier for decades. Within two weeks in September 2026, the federal government committed roughly $2.5 billion across two separate agreements to begin changing that.

The Defense Logistics Agency (DLA) contract with Elmet Technologies closed on 11 September 2026. The Masan High-Tech Materials equity and supply agreement followed on 24 September 2026. The back-to-back timing is not coincidence. It is a sequenced supply chain strategy, and anyone tracking critical mineral policy or defence supply chain risk needs to read the architecture, not just the headlines.

This piece breaks the deal into its three working parts: the DLA stockpile contract, Elmet’s equity stake in Masan, and the eight-year supply agreement that connects them. Here is how those parts fit together as a system, where the genuine execution risks sit, and what it would take for this to actually reduce US tungsten dependency rather than simply signal an intention to.

The honest read sits in the tension between ambition and delivery. This is a serious piece of industrial policy. It is also a long way from proven.

The two-week sprint that rewired America’s tungsten strategy

The sequence began on 11 September 2026, when Elmet Technologies, a subsidiary of Elmet Group (NASDAQ: ELMT), signed an exclusive offtake agreement with DLA Strategic Materials. The structure is an indefinite delivery, indefinite quantity (IDIQ) contract, meaning the government commits to a framework and a ceiling rather than a fixed purchase.

The ceiling runs to $2 billion. The guaranteed funded minimum sits at $150 million of tungsten ore, concentrates, and sodium tungstate. The base ordering period runs five years, through 30 August 2031, with a two-year extension option at DLA’s discretion through 30 August 2033.

Alongside the contract, a separate US government investment of roughly $450 million flowed into Elmet Group itself. That distinction matters. Federal capital is underwriting both sides of the equation: the demand side through the stockpile contract, and the supply infrastructure through Elmet’s US manufacturing base across Maine, Michigan, and Ohio.

The Masan-Elmet deal does not exist in isolation: it sits inside a broader critical minerals strategy that has accelerated federal procurement authorities, expanded the scope of the Defense Production Act for mineral inputs, and repositioned allied-nation supply agreements as instruments of strategic competition rather than routine commodity sourcing.

The Masan stake that makes the contract executable

A guaranteed federal demand signal is only useful if there is material to fill it. That is where the second announcement, on 24 September 2026, comes in.

Elmet agreed to acquire a 4.99% equity stake in Masan High-Tech Materials for approximately $124.75 million to $125 million, implying a company valuation of around $2.5 billion. Masan Group, the parent conglomerate, retains controlling ownership of roughly 87.46% after the deal. The market read it favourably: Masan High-Tech shares climbed 7% on the announcement morning.

Completion is expected in the first half of October 2026, subject to regulatory and corporate approvals. Read together, the two agreements tell you this is coordinated industrial policy, not two firms doing routine business.

Why tungsten, and why Vietnam sits at the center of this deal

To understand why the US government would move this quickly, you need to understand what tungsten does and where it comes from.

Tungsten is prized for exceptional hardness and high-temperature performance, which makes it difficult to substitute in the applications that matter most to defence and advanced manufacturing. The US Department of Defense formally designates it a critical mineral. Its uses include armour-piercing munitions, aerospace components, high-temperature alloys, and semiconductor manufacturing equipment.

The defence dependency in one list Armour-piercing munitions. Aerospace components. High-temperature alloys. Semiconductor manufacturing equipment. Every one of these is a category where supply interruption directly affects readiness.

The structural problem is China. Public assessments from US government and technical bodies consistently describe China as accounting for a large majority of mined tungsten output and an even greater share of refined product and downstream materials.

The structural problem predates this deal by years, and the pathways available to the US for tungsten supply chain diversification have been narrowing as China has tightened its grip on concentrate upgrading and APT production across successive policy cycles.

Here is the part most readers underestimate: the processing stage is the more dangerous chokepoint, not the ore itself. Critical steps such as concentrate upgrading, ammonium paratungstate (APT) production, and high-purity powder manufacture are heavily concentrated in China. Ore availability elsewhere means little if the refining capacity to convert it stays in one country’s hands.

That concentration creates several distinct ways supply can be squeezed:

• Export controls imposed by China
• Broader geopolitical tensions between China and importing nations
• Environmental crackdowns across China’s domestic mining sector
• Internal Chinese demand surges that pull material away from export
• Sharp price spikes triggered by any of the above

This is exactly why Vietnam matters. Per US Geological Survey data, Vietnam ranked as the world’s second-largest tungsten producer in 2024, behind only China. The country’s annual output of approximately 3,400 metric tons comes virtually entirely from a single asset: Masan’s Nui Phao mine, one of the largest tungsten operations outside China.

USGS tungsten production data for 2024 confirms Vietnam’s position as the world’s second-largest producer, with China maintaining a commanding lead in both mined output and, critically, the downstream refining stages where geopolitical leverage is most concentrated.

Nui Phao is not standing still. Expansion plans announced in June 2026, targeting both Nui Phao and the adjacent Nui Chiem area, could add up to 115 million metric tons of tungsten-polymetallic resources. For a US buyer trying to bypass the Chinese processing chokepoint, Vietnam is the most credible near-term alternative on the board, which is precisely why the Masan deal bundles both mined supply and conversion services rather than ore alone.

How the deal is structured to lock in supply from mine to manufacturer

The equity stake grabs the headlines, but it is not where the strategic security lives. A 4.99% holding gives Elmet limited governance rights and no operational control over Masan. That is deliberate.

Pairing a sub-5% stake with a long-term supply contract is a relationship anchor, not a control mechanism. The stake signals commitment and aligns interests without forcing Elmet to absorb the governance complexity or capital risk of a controlling position. The real security sits in the commercial contract.

The supply contract terms that matter

The supply and processing agreement is where the deal earns its strategic label. The key terms:

• Annual committed volume: approximately 1,250 metric tons of WO3-equivalent
• Duration: minimum eight years
• Estimated aggregate gross revenue for Masan: approximately $1.5 billion over the initial term at prevailing prices
• Scope: both mined output from Nui Phao and conversion or processing services from Masan’s Vietnamese refining complex
• Effective date: upon equity closing, anticipated first half of October 2026

That final scope point is the architectural detail that separates this from a routine offtake deal. Most supply contracts secure ore. This one secures ore and the refining that turns it into usable material, addressing the processing chokepoint directly, where Chinese leverage is highest. If you are assessing whether the deal delivers real supply chain security or just headline volume, the processing services component is what determines the answer.

Jefferies Singapore acted as sole financial advisor to Masan High-Tech on the transaction. Masan has framed the deal explicitly as a first step, stating it intends to pursue comparable partnerships across additional key markets. That signals a template designed to be replicated, not a one-off.

What precedent says about the gap between announcing supply chain deals and delivering them

Announcements are easy. Delivered volumes are hard. The empirical record of comparable US critical mineral diversification efforts is the most honest tool available for calibrating what to expect here.

Consider rare earths. The US Department of Defense funded Lynas Rare Earths to build processing capacity in Texas, creating a non-Chinese supply route for key rare earths. Even that well-funded, government-backed project has faced the multi-year permitting, engineering, and ramp-up sequence that turns an announcement into reliable throughput slowly rather than immediately.

The Mountain Pass case is starker still.

The precedent that should temper the optimism US support helped restart mining at Mountain Pass, California, through MP Materials, but for years a substantial share of processing continued in China. Restoring domestic mining proved far easier than rebuilding a full domestic value chain.

These precedents, alongside the broader Minerals Security Partnership framework coordinating investment among allied nations, point to three lessons that apply directly to the Masan-Elmet structure:

China’s processing monopoly extends well beyond tungsten, covering cobalt refining, rare earth separation, and lithium hydroxide conversion at scale, which means the architectural challenge the Masan deal attempts to solve in one mineral category is being replicated simultaneously across the full critical minerals portfolio that Western defence and technology sectors depend on.

1. Treat the timeline as long. Building resilient supply chains outside China typically takes many years. The eight-year contract horizon is consistent with observed project realities, and should be read as a minimum for visible impact rather than a delivery date.
2. Full-chain integration is the right architecture. Coupling mining, refining, and manufacturing under long-term agreements is the approach most consistently linked to successful diversification. The Masan-Elmet structure attempts exactly this, which is a point in its favour.
3. Single deals reduce but do not eliminate dependency. The 1,250 tonnes per year is significant but not sufficient alone. Meaningful reduction in Chinese exposure requires a portfolio, not one transaction.

The historical record does not argue against this deal. It argues that you should watch for whether complementary supply agreements follow before concluding that US tungsten dependency has been structurally reduced.

The risks this deal does not resolve, and the variables that will determine whether it matters

The precedent record explains the pattern. The forward-looking question is what this specific structure leaves unresolved. Four risk dimensions stand out:

• Governance limitation: The 4.99% stake gives Elmet no meaningful control over Masan’s operational or strategic decisions. The long-term commercial contracts are the sole supply security mechanism, carrying all the counterparty and performance risk that implies.
• Execution risk: The minimum eight-year term depends on sustained production at Nui Phao and reliable operation of Masan’s Vietnamese refining complex across a long horizon. Multi-year performance is never guaranteed in critical mineral supply.
• Geopolitical positioning: Vietnam maintains balanced relations with both China and the United States. Chinese pressure over the strategic direction of Vietnamese mineral exports is a plausible risk channel across an eight-year window, even if it is not a near-term threat.
• Scale relative to dependency: 1,250 tonnes WO3-equivalent per year and $1.5 billion over eight years are material but not transformative against total US consumption and China’s dominant processing capacity.

What to watch, and what remains unconfirmed

The most important open question is not whether initial volumes flow. It is whether the structure holds under geopolitical or commercial stress over a full eight-year term.

Two leading indicators are worth tracking. The first is Vietnam’s trade policy signals, which will reveal whether Hanoi’s balancing act tilts under pressure. The second is any escalation in Chinese export controls, which would test both the value and the resilience of non-Chinese supply.

It is also worth being precise about status. As of 24 September 2026, the equity deal had not closed, with regulatory and corporate approvals still pending. No named independent defence policy or critical-minerals analysts had commented specifically on the transaction in accessible reporting, and no regulatory agency statements had surfaced. The coverage so far is announcement framing. The verdict on execution will come later.

Whether this deal shifts the structural picture, or just the optics

The strongest case for this deal is its architecture. By bundling mining at Nui Phao, refining in Vietnam, and manufacturing at Elmet’s US plants under a single long-term agreement, and by linking that chain to a federal stockpile contract, the structure matches what precedent suggests gives diversification the best chance of sticking. Full-chain integration is the feature, not the equity stake.

The verdict on impact is more measured. The deal meaningfully reduces spot-market and single-event disruption risk for Elmet’s specific throughput. It does not move the structural needle on US tungsten dependency until several comparable partnerships follow and the National Defense Stockpile is demonstrably rebuilt.

The number nobody is watching closely enough The DLA contract carries a $150 million guaranteed minimum against a $2 billion ceiling. Whether federal intent converts into actual purchased volume, closing that gap, is what separates a genuine stockpile rebuild from a policy signal.

The National Defense Stockpile has operated well below target levels for several critical minerals for years, and the DLA contract structure, with a guaranteed $150 million minimum against a $2 billion ceiling, reflects the gap between policy intent and actual procurement that has characterised stockpile management across multiple administrations.

Combined with the roughly $450 million government investment in Elmet, the federal commitment reaches around $2.45 billion. That is a real bet. Whether it pays off in reduced dependency rather than headline value depends on two forward signals worth monitoring:

• Whether Masan pursues the additional partner-market deals it has flagged
• Whether the DLA contract translates into actual stockpile drawdown, or remains a ceiling-value commitment never fully exercised

Track that drawdown against the ceiling over the next 12 to 24 months, and you will have a sharper read on whether US tungsten policy is executing or stalling than anyone following headline announcements alone.
