Classification
EU CLP Classification
Under EU Regulation No. 1272/2008 on the classification, labelling, and packaging of substances and mixtures (EU CLP), companies are required to ensure the safe use of substances by clearly identifying and communicating their hazards.
Cobalt Institute plays an active role in supporting the appropriate classification of cobalt and cobalt-containing substances. This includes generating scientific and regulatory evidence, engaging with regulatory authorities, and developing position papers when necessary to ensure that classifications are scientifically justified and proportionate.
An overview of the classification and concentration limits under CLP of the substances under the Institute’s portfolio is available below (for further details please email REACHinfo@cobaltinstitute.org). Please note that the information in the overview will apply only to pure substances and targets CLP requirements. Therefore, it only applies to the European Union territory.
For the substance cobalt (EC 231-158-0, CAS 7440-48-4) in powder form, a particle-size based classification is used. In order to determine the respirable fraction of any cobalt powder, the “Size Weighted Respirable Fraction” (SWeRF) is calculated, taking into account the particle size distribution and the probability that the particles reach the alveoli, and using cumulative particle size distribution.
This particle-size based classification can be overruled by an in vivo testing result on an individual powder only.
If you have any questions on cobalt and cobalt compound EU CLP classifications, please contact the CI Secretariat (REACHinfo@cobaltinstitute.org).
GHS Classification
The Globally Harmonised System (GHS) of classification and labelling and packaging of chemicals provides a basis for classification of chemicals by types or hazard and a harmonised hazard communication.
For an overview of the classification of these substances under the Institute’s portfolio under GHS, please refer to the information below.
