Socio-Economic Analysis (SEA)
Definition
A Socio-Economic Analysis (SEA) is a cost-benefit assessment required in REACH authorisation applications where the applicant argues that socio-economic benefits outweigh risks, or where adequate control cannot be demonstrated. The SEA must quantify the benefits of continued authorised use (economic and social value to applicants and downstream users) against the health and environmental costs of the risks. SEA methodology follows ECHA guidance and must include a scenario analysis of what would happen if authorisation is refused.

Practical Explanation (Compliance Context)
A weak SEA is one of the primary reasons authorisation applications fail or receive short review periods. The SEA must be quantified wherever possible, drawing on production volumes, value-added data, employment figures, and substitution costs. Industry sector data from trade associations strengthens individual applications. Joint applications combining SEAs across multiple applicants benefit from more representative economic data.
