Abstract: This paper briefly introduces the global framework of chemical metrology and outlines the work progress made by the International Bureau of Weights and Measures (BIPM), the Consultative Committee for Amount of Substance: Metrology in Chemistry and Biology (CCQM), the Regional Metrology Organizations (RMOs) and related international organizations. It describes the development trend of international mutual recognition under the CIPM MRA framework and presents the highlights of China's international cooperation activities. The international cooperation in chemical metrology is growing in response to the rising demand in essential emerging areas, which is characterized by an enhanced cross-field and cross-disciplinary pattern. The focus on knowledge transfer and capacity building for emerging economies has continued. China has been a more active participant in international cooperation in chemical metrology, with its role gradually shifting to an initiator, which represents its undertaking in the international community of metrology.
