02ABOUT

Neutral Sourcing, Reliable Supply

Murua Korea Corp. is the Korean company of Murua Group AG, headquartered in Zug, Switzerland — a Seoul-based strategic metals and advanced materials supply chain platform strengthened by the group’s planning, sourcing, compliance and process capabilities.

It is not a newly formed local entity: it builds on a Korean operating base dating back to 2023 and was strengthened through Murua Group’s acquisition of JPEnergy in Korea in November 2025.

Rather than offering products alone, we address what buyers actually need — demand planning, diversified sourcing pathways and local delivery coordination — in Korean and in the same time zone.

MESSAGE

A supply chain built on trust

Thank you to every customer and partner who has taken an interest in Murua Korea.

Competitiveness in semiconductors and advanced industries now depends on how reliably critical materials can be secured, and supply chains that lean on a single country can be disrupted at any time. Murua Korea was founded to supply the ultra-high-purity metals and strategic materials Korean industry needs through neutral, transparent routes, backed by Murua Group's global sourcing network and its European refining and smelting partners.

Our first principle is simple: deliver the promised quality and quantity at the promised time. Every transaction rests on origin traceability and compliance procedures, and we work alongside our customers' purchasing and quality teams in the same language and the same time zone.

We intend to be more than a supplier — a partner that shares responsibility for our customers' long-term supply security. We look forward to your continued interest and support.
