New ISO Rare Earth Water Content Standard Led by Baotou Institute Released

Recently, the international standard "Rare Earths—Determination of Water Content in Rare Earth Products—Gravimetric Method" (ISO 24548:2025), led by the Baotou Rare Earth Research Institute in its development, was officially released. This marks another significant breakthrough for Baotou in the field of international rare earth standardization.

In industrial competition, the right to formulate international standards holds a critical position. For a long time, the international rare earth industry has faced challenges such as inconsistent terminology and varying detection methods, which have hindered international trade and technical cooperation. To date, seven international standards in the field of rare earths, led or participated in by Baotou, have been successfully released. These standards cover multiple core aspects, including rare earth terminology, product detection, and scrap recycling, accounting for nearly half of the published international rare earth standards. This fully demonstrates that Baotou's voice and influence in the formulation of international standards for the global rare earth industry are continuously increasing.
