Posco International rare earth investment strengthens EV supply chain strategy

Efforts to secure critical materials for electric vehicle production are intensifying as companies move upstream in the supply chain. Posco International has initiated a strategic investment program focused on rare earth elements, aiming to strengthen its position in the EV ecosystem and reduce dependency on external suppliers. Through collaboration with Posco Investment, the company has launched a KRW 25 billion corporate venture capital fund to support advanced material technologies.

The initial investment targets a domestic specialist in rare earth separation and refining. This company has developed proprietary processes to extract and purify heavy rare earth elements such as dysprosium and terbium, which are essential for high-performance permanent magnets used in EV traction motors. The technology enables oxide purification levels exceeding 99.5% and metal refinement reaching 99.9%, ensuring high efficiency and reliability for automotive applications.

Global expansion strategy for rare earth supply

Beyond domestic investments, Posco International is expanding its footprint across international markets to build a resilient raw material procurement network. In Malaysia, the company is working with a local partner on a USD 30 million rare earth separation and refining project. This initiative is expected to move into mass production after validating mining and processing systems.

Additional developments are underway in Laos, where participation in regional projects is projected to secure approximately 4,500 tons of annual production capacity across Southeast Asia. Future investments are expected to scale this capacity to over 10,000 tons, reinforcing supply stability for EV components and reducing exposure to market volatility.

North America joint venture and future production plans

In the North American market, Posco International is collaborating with ReElement Technologies Corporation to establish a rare earth separation and refining facility in the United States. The plant is designed with an annual capacity of 3,000 tons and is scheduled to begin mass production in the second half of 2027.

Looking ahead, the company plans to further integrate its operations by establishing permanent magnet production capabilities of 3,000 tons per year by 2028. This move aligns with its strategy to create a vertically integrated rare earth value chain, linking raw material processing with traction motor core manufacturing to enhance competitiveness in the EV components market.

Through these coordinated investments and global partnerships, Posco International is positioning itself as a key player in the evolving EV supply chain, ensuring long-term access to critical materials while supporting the transition toward electrified mobility.
