The global antimony market in 2026 has entered a period of structural realignment, characterized by a sharp pricing correction in the first half of the year and a frantic U.S.-led effort to decouple from Chinese supply chains. After the historic price spikes of 2024 and 2025: driven largely by Chinese export restrictions: the market is now navigating a "plateau at height." While prices have retreated from their record peaks, they remain fundamentally elevated compared to the previous decade, underpinned by the intensifying "geopolitical tax" on critical minerals.
As of July 2026, the industry is closely watching three converging factors: China’s temporary suspension of its civilian export ban, the U.S. Defense Logistics Agency’s (DLA) massive $245 million stockpile injection, and the accelerating development of the Stibnite Gold Project in Idaho.
H1 2026: The pricing correction and regional divergence
Following the extreme volatility of late 2025, antimony prices in North America saw a significant softening in the first half of 2026. Domestic prices for antimony trioxide and metal fell approximately 22.5% during H1, a move analysts attribute to a combination of inventory liquidation by industrial end-users and a temporary easing of immediate supply fears.
In China, the world’s dominant producer, 1# antimony ingot was trading at approximately 109,500 yuan/mt in early July, a notable decline from the 149,500 yuan/mt levels seen just twelve months prior. This correction was facilitated by a strategic pivot in Chinese production; Beijing has planned a 5% production increase for the second half of 2026, aiming for a total annual output of roughly 80,000 tonnes to maintain market share and stabilize domestic industrial input costs.
| Market Metric | Value (H1 2026) | Trend vs. 2025 |
|---|---|---|
| North American Price Drop | ~22.5% | Correction |
| China 1# Ingot Price | 109,500 yuan/mt | Downward |
| Global Market Valuation | $2.6 Billion | Growing |
| China Production Target | 80,000 tonnes | +5% YoY |
The China pivot: Imports surge and the November deadline
Despite its status as the top producer, China’s internal appetite for high-grade antimony ore has surged. Between January and May 2026, Chinese imports of antimony ore and concentrate skyrocketed by 209% year-over-year, reaching 48,659 tonnes. This aggressive procurement suggests that while China is increasing ingot production, it is increasingly reliant on external feedstock to maintain its smelting dominance.
Crucially, the current market calm is pinned to a fragile policy window. China’s temporary suspension of its export ban for civilian-use antimony is scheduled to remain in place through November 2026. This window has allowed global manufacturers of flame retardants: which account for 55% of total demand: to restock. However, the impending November expiration creates a "hard floor" for prices; any sign that the suspension will not be renewed is expected to trigger a secondary wave of panic-buying in Q4.
The $245M stockpile play: U.S. strategic defense response
The United States, which currently imports over 80% of its antimony, has accelerated its efforts to insulate the defense sector from supply shocks. The Defense Logistics Agency (DLA) has finalized a multi-year contract worth up to $245 million for the National Defense Stockpile (NDS).
This agreement aims to secure 3,026 tonnes of antimony over a five-year period, a volume that underscores the metal's criticality in defense applications. Antimony is essential for hardening lead alloys in ammunition, manufacturing infrared sensors, and producing high-strength military-grade steel. By moving to lock in these volumes during the 2026 price dip, the U.S. is effectively building a strategic buffer against the long-term threat of a permanent Chinese export embargo. This move follows broader initiatives like the White House's $1 billion equity play for critical minerals, reflecting a whole-of-government approach to supply security.
Domestic frontrunners: Stibnite and the push for U.S. production
While stockpiles provide short-term security, the long-term solution lies in domestic extraction. Three primary projects are currently leading the U.S. antimony resurgence:
- Perpetua Resources (Stibnite Project, Idaho): The Stibnite project remains the most advanced prospect. Once operational, it is expected to provide approximately 35% of total U.S. antimony demand. The project has benefited from recent permitting reforms in North America, which have helped streamline environmental reviews for critical mineral assets.
- US Antimony Corp (NYSE Uplist): Operating in Montana, US Antimony Corp is currently pursuing an NYSE uplisting to attract the institutional capital necessary to scale its domestic smelting and mining capacity.
- NevGold (Nevada Brownfield): NevGold is advancing a brownfield project in Nevada, aiming to leverage existing infrastructure to bring new supply online by the end of the decade.
These domestic efforts are mirrored globally as other jurisdictions seek to challenge the monopoly. For instance, Galway Metals recently updated its resource estimates at the Clarence Stream project, signaling that a broader North American supply base is slowly taking shape.
Beyond defense: The demand drivers for 2026–2035
While defense applications often capture headlines, the commercial drivers for antimony are equally robust.
- Flame Retardants: Holding 55% of global demand, the construction and electronics sectors remain the bedrock of the market. Stricter global fire safety regulations in 2026 have made antimony trioxide nearly indispensable in high-performance plastics.
- Photovoltaic (PV) Glass: The solar industry’s shift toward higher-efficiency glass has increased the use of antimony as a clarifying agent.
- Energy Storage: Next-generation liquid metal batteries, which use antimony-calcium alloys for long-duration grid storage, are moving from the pilot phase to commercial deployment.
Outlook: Navigating the 2026-2035 horizon
The global antimony market is currently valued at approximately $2.6 billion in 2026. Projections suggest this will expand to $4.7 billion by 2035, representing a compound annual growth rate (CAGR) of over 6%.
For investors looking for critical minerals stocks to buy in 2026, the focus should remain on companies with clear paths to production and significant de-risking via government grants or off-take agreements. The "antimony price trend 2026" shows a market that has matured past the initial panic of 2024. However, the underlying supply-demand deficit is far from resolved.
With China's export suspension nearing its November expiration, the current price retreat should be viewed not as a return to the "old normal," but as a tactical pause before the next phase of the critical minerals race. Operators and investors who use this H1 lull to secure supply or positions in domestic producers will likely be the best-positioned when the next supply crunch arrives.

Antimony prices fell 22.5% in H1 2026, but don't let the correction fool you. With China’s export suspension expiring in November and the US DLA launching a $245M stockpile play, the strategic race for this critical mineral is just heating up. #MiningNews #Antimony #CriticalMinerals #SupplyChain2026
