Guidance on the Chemical Safety Report

REACH requires the submission of a Chemical Safety Report (CSR) for all substances subject to registration in quantities of 10 tonnes or more per annum per registrant or by downstream users if their uses are not addressed by their supplier. This report forms part of the registration process or ‘registration dossier’ and should be a readily understandable, stand-alone document.

The chemical safety report (CSR) under REACH is divided into 2 parts:

Section A: the summary of relevant risk management measures (RMM) for the identified use(s) of a substance, based on exposure scenario(s)and declarations that the RMM are implemented by the organisation preparing the CSR and communicated to downstream users;
Section B: the conclusions of the chemical safety assessment (CSA) process according to Annex I of the REACH Regulations and the supporting factual information to arrive at these conclusions. The CSA contains a detailed summary of the environmental and human health hazards properties of a substance, together with an assessment of exposure and risk where such an assessment is required (Figure 1).

The CSR is an important part of the REACH process as it is the source from which information is communicated further down the supply chain, by extraction for use in extended safety data sheets (eSDS).The principles applied, the assumptions made and the conclusions drawn should be easily identifiable without the need to revert to the underlying substance data sets (i.e. the IUCLID substance data set). The preparation of the CSR needs to be carefully considered and requires a high level of expertise.
