Extended Safety Data Sheet (eSDS)
Definition
An extended Safety Data Sheet (eSDS) is a Safety Data Sheet that includes one or more Exposure Scenarios appended to Section 16. The eSDS is required when a Chemical Safety Report has been prepared for the substance (i.e., hazardous substances or PBT/vPvB substances above 10 t/year). It communicates the specific conditions of safe use (operational conditions, risk management measures) for each identified use to downstream users in the supply chain. The eSDS is the primary REACH communication tool for chemical supply chains.

Practical Explanation (Compliance Context)
Downstream users receiving an eSDS must check whether their use is covered by the appended exposure scenarios. If their use is not listed, or their operating conditions exceed the ES parameters, they must address the uncovered use. The eSDS annex can contain dozens of exposure scenarios for complex substances; compliance teams need systematic tools to map their uses against each ES.
