Chemical Safety Assessment (CSA)
Definition
A Chemical Safety Assessment (CSA) is a hazard and risk assessment conducted by a REACH registrant for a substance manufactured or imported above 10 tonnes per year that is classified as hazardous or is PBT/vPvB. The CSA follows the methodology in Annex I and includes: hazard assessment (physico-chemical, human health, environmental); PBT/vPvB assessment; exposure assessment; and risk characterisation. The results are documented in the Chemical Safety Report (CSR).

Practical Explanation (Compliance Context)
The CSA and CSR are the scientific backbone of REACH registration for higher-tonnage and hazardous substances. Downstream users must check that their uses are covered in the registrant’s exposure scenarios; uncovered uses require the downstream user to prepare their own brief CSR or notify the registrant to add the use. The CSA also drives the content of the extended SDS (eSDS) communicated down the supply chain.
