Refined cobalt is a key raw material for manufacturing products such as superalloys, cemented carbides, and magnetic materials. Europe, as a significant global center for aerospace, high-end manufacturing, and chemicals, is also one of the core consumer markets for refined cobalt. Its price dynamics will significantly influence the global market structure and pricing. As the largest port in Europe, Rotterdam aggregates raw materials from major producing regions worldwide, as well as spot cargo circulating within the region, forming a mature storage, logistics, and trading network. Its prices truly reflect the arrival costs, supply-demand balance, and regional premiums in the European market, providing a crucial price reference benchmark for market participants. Therefore, SMM plans to add a new price index, “SMM Refined Cobalt (In warehouse Rotterdam)", to provide the industry with more comprehensive price references.
