A planned joint venture between Plansee U.S. Holding Corp. and Manhattan Five Partners LLC is intended to strengthen tungsten supply security in the United States, according to a May 19 statement from the CERATIZIT Group, a Plansee Group business area.

The goal, according to the Ceratizit statement, is to establish a strategic tungsten oxide stockpile in the U.S., reduce reliance on foreign sources for tungsten, and to support government, defense and critical industry demand. The agreement combines Plansee’s industrial and technical experience in tungsten oxide processing with Manhattan Five’s capabilities in structuring, financing and managing large-scale infrastructure and strategic asset platforms.

As part of the project, Plansee intends to expand tungsten oxide production capacity at Global Tungsten & Powders (GTP) in Towanda, Pennsylvania, to about 12,000 tons per year. GTP is a division of CERATIZIT Group. Initial deliveries are expected to begin in 2026.
