Building a Strategic Tungsten Oxide Stockpile in USA
Plansee US Holding Corp., an affiliate of the Plansee Group, and Manhattan Five Partners LLC have entered into a definitive collaboration framework agreement outlining the formation of a joint venture to establish a strategic tungsten oxide stockpile in the United States.
This initiative is designed to support U.S. national security objectives, strengthen domestic supply chain resilience, and reduce reliance on foreign adversarial sources for critical minerals. The project is being developed in alignment with U.S. government priorities and is structured to potentially leverage programs administered from the Department of War (DOW), Department of Energy (DOE), Department of Commerce (DOC), Development Finance Corporation (DFC), the Export-Import Bank of the United States (EXIM).
The partnership combines Plansee’s industrial and technological leadership in tungsten oxide processing with Manhattan Five’s expertise in structuring, financing, and managing large-scale infrastructure and strategic asset platforms.
As part of the initiative, Plansee intends to expand production capacity for tungsten oxide at its US facility in Towanda, Pennsylvania to approximately 12 000 t/a within a short timeframe. The stockpile will consist of tungsten oxide derived from recycled tungsten scrap and non-adverse-country concentrates, ensuring alignment with U.S. sourcing, traceability, and supply chain security requirements. Initial deliveries are expected to commence in 2026.
A significant portion of production will support a strategic tungsten oxide reserve intended to serve U.S. government, defense, and critical industry demand. Under the joint venture structure, Manhattan Five will oversee warehousing, logistics infrastructure, and long-term asset management, while Plansee will lead production expansion and supply.
Tungsten is widely recognized as a critical mineral essential to defense systems, aerospace applications, energy infrastructure, and advanced manufacturing. Through its Global Tungsten & Powders (GTP) facility in Towanda, Pennsylvania, Plansee already supplies a significant share of U.S. demand. The establishment of a strategic tungsten oxide stockpile represents a meaningful step toward strengthening long-term domestic supply independence.
