US Antimony DLA contract strengthens US strategic antimony supply

US Antimony

US Antimony DLA contract marks a major step in rebuilding North America’s antimony supply chain and defense resilience. The five-year, fixed-price US Antimony DLA contract is worth up to $245mn and targets nearly 6.7mn lbs of metal. As a result, the US Antimony DLA contract positions the company as the core domestic supplier for this critical mineral.

DLA moves to secure domestic antimony for the stockpile

The US Defense Logistics Agency awarded US Antimony a contract to supply ingots for the National Defense Stockpile. Deliveries will go to the Scotia Depot in New York, with first shipments expected this week under the multi-year framework. The tender directly cited US Antimony as the only source of qualifying domestic-grade material, underscoring its unique position.

US Antimony operates the only two antimony smelters in North America, in Montana and at Madero in Mexico. The Madero smelter reopened in April, restoring additional regional capacity for processed antimony products. Together, these assets give the company integrated upstream and midstream control from ore to ingot.

Antimony’s role in defense and critical minerals strategy

Antimony is a core ingredient in many strategic and military applications, especially for alloys and flame retardants. It is used in batteries, cables and specialized defense components, making secure supply a national priority. Therefore, the contract fits into Washington’s broader push to rebuild domestic and allied capacity for critical minerals.

The DLA has expanded its National Defense Stockpile purchases across several critical minerals this year. Recent tenders and RFIs have targeted cobalt, bismuth, high-purity aluminum, scandium flake, niobium and ferro-niobium. This portfolio approach aims to reduce dependence on unstable or adversarial foreign sources.

Market implications for antimony and strategic metals

The US Antimony DLA contract sends a strong demand signal to antimony markets and potential investors. Long-term, fixed-price offtake can support capital spending, operational stability and potential future expansions. Meanwhile, the contract highlights the value of having permitted, operating smelter capacity in politically stable jurisdictions.

Global antimony supply remains concentrated, with China still dominating mine output and processing. As a result, Western buyers increasingly seek diversified supply chains, including North American and allied producers. US Antimony’s position as the only North American smelter operator makes it a central part of this shift.

The Metalnomist Commentary

This deal effectively transforms US Antimony from a niche smelter into a strategic asset for US defense planners. For the broader critical minerals sector, it signals that long-dated government offtake contracts may become a key financing tool for non-Chinese supply.
