promoting the sustainable and responsible production and use of cobalt in all forms


Industry research has also identified some further hazards for physico-chemical, human health and environmental endpoints, and CI and CoRC members have agreed on the appropriate self-classifications. Self-classifications for cobalt and cobalt compounds have been derived according to the UN Globally Harmonized System, and full details of appropriate substance self-classifications under EU CLP are available via the Cobalt REACH Consortium website.

For inhalation carcinogenicity, the self-classifications of cobalt compounds (cobalt metal, cobalt monoxide and cobalt dihydroxide) were established in 2013, 2016 and 2017 respectively. For reproductive toxicity and specific target organ toxicity, self-classifications of several cobalt compounds were adopted in 2018. The industry actions for responsible assessment and classification of cobalt substances related to these self-classifications can be found below:
