About United States Antimony Corporation
United States Antimony Corporation, a for-profit manufacturer headquartered in Cox Gulch, Montana, supplies antimony metal ingots to the Department of Defense's Strategic Materials division as a prime contractor under full-and-open, non-set-aside procurement. The vendor operates as the sole domestic qualified source for high-purity antimony metal (99.65% specification) and holds a single-award five-year Indefinite Delivery Indefinite Quantity (IDIQ) contract with the Defense Logistics Agency (DLA) Strategic Materials division, awarded September 22, 2025, with a $245 million ceiling and an ultimate completion date of September 21, 2030.
United States Antimony Corporation's federal footprint is narrowly concentrated and entirely dependent on one customer. The Defense Logistics Agency Strategic Materials division accounts for 100% of awards and 100% of combined potential value across all four prime contracts and IDIQs in the recent portfolio. The vendor holds a single-award IDIQ contract (SP800025D0007) supporting approximately 6.7 million pounds of antimony metal ingots across the five-year performance period, with annual delivery quantities ranging from 743,425 to 1.6 million pounds. Two delivery orders have been placed against the IDIQ to date: a $9.95 million first delivery order issued September 26, 2025 (ultimate completion September 25, 2027), and a $1.9 million second delivery order issued January 15, 2026 (ultimate completion January 14, 2028), both utilizing fixed-price pricing with economic price adjustment terms. Manufacturing and all deliveries occur at the vendor's Thompson Falls, Montana facility, with delivery directed to the DLA Strategic Materials Scotia Depot in New York.
The IDIQ was awarded as a sole-source acquisition under FAR 6.302-3(a)(2)(i) to maintain industrial mobilization supplies, with United States Antimony Corporation identified as the only qualified domestic supplier meeting specifications. Of the $257.4 million combined potential value across all awards, $12.4 million has been obligated (5% of ceiling). Two awards totaling $11.9 million in combined potential value reach ultimate completion within the next twenty-four months and face recompete exposure. The vendor carries no subcontract footprint and operates exclusively as a prime on strategic materials supply for defense industrial base resilience and National Defense Stockpile objectives.
