GHS Classifications

Classifications according to the Globally Harmonized System of Classification and Labelling of Chemicals (GHS) for the same chemical can differ across countries/regions. For more information on the classifications found via eChemPortal, see the information made available by each individual data provider.

 

The main reasons for diverging classifications are the use of different underlying datasets, a difference in interpretation of the underlying data (e.g. due to difference in data availability or a different rationale for selecting a study over another), a different application of the classification criteria, or a mix of these reasons. As well, classifications can be based on different forms of a substance or on classification of an analogous substance.

 

Information on the Globally Harmonized System of Classification and Labelling of Chemicals (GHS) can be found on the website of the United Nations Economic Commission for Europe (UNECE).

 

See also, the results of a pilot exercise performed in the context of the Organisation for Economic Co-operation and Development (OECD) to analyse possible reasons leading to diverging classification outcomes of chemicals listed in Annex III of the Rotterdam Convention: Series on Testing and Assessment No. 119 - Classification and Labelling of Chemicals According to the UN Globally Harmonized System: Outcome of the Analysis of Classification of Selected Chemicals listed in Annex III of the Rotterdam Convention.
