London, August 11th (Argus) - Ucore Rare Metals, an American rare earth developer, and Sumitomo Corporation (Americas) have signed a cooperation agreement to purchase raw materials and develop the sales of separated rare earth products, expanding Japan's role in emerging supply chains outside China.
The two companies stated that under the agreement, the two companies will collaborate to purchase materials for Ucore's planned strategic metal complex in Louisiana and develop the purchase commitments for processing rare earth products. Sumitomo will also distribute selected products to Japan and other markets.
What is more notable about this statement is the potential benefits it may bring rather than the guarantees it provides. Neither company has disclosed the quantity of raw materials, the quantity of purchase commitments, pricing terms, investment commitments, or the duration of the contract. The press release also does not indicate whether Japanese customers have agreed to purchase materials from this project.
Ucore is seeking to establish a rare earth separation business in North America, while Japanese companies are increasingly seeking alternative suppliers to China's supply. In May this year, Japan and Australia committed to deepening cooperation in key mineral sectors, including strengthening business connections between producers and Japanese manufacturers.
The demand issue still exists
Many projects in the rare earth industry still lack a firm demand commitment.
In June this year, Amanda Lacaze, the CEO of Lynas Rare Earths, warned that governments and enterprises were overly focused on increasing supply but failed to ensure sufficient downstream demand and long-term purchase commitments.
Sumitomo has a track record in this industry. The Japanese trading company agreed in 2023 to be the exclusive distributor of praseodymium and neodymium oxides produced by MP Materials, while the rare earth factory Summit Atom rare earth Company continues to produce separated materials through the supply chain, which now includes the raw materials from the Kangankunde project of Lindian Resources in Malawi.
This agreement also aligns with Japan's broader strategy of combining financing, marketing, and purchase commitments. The Japan Organization for Metals and Energy Security has established rare earth partnerships with Sojitz, Toyota Tsusho, and Iwatani, linking investments directly to future supply arrangements.
This transaction also occurred after the rare earth market experienced significant fluctuations over the past nine months. Argus reported that the price of praseodymium and neodymium oxide from China rose by nearly 70% from November 2025 to February 2026, while the price of oxide dysprosium in the United States rose by 80% during the same period, strengthening the commercial rationale for establishing alternative supply chains.
