  • As the substance does not have a threshold, the "Socio-economic Analysis" route will be chosen. This analysis will have to show that the benefits related to the granting of the authorisation outweigh the risks associated.
  • Whether the substance works with a threshold or not is not determined for these endocrine disruptors.
  • In addition to the CSR and Analysis of Alternatives, the applicant will have to conduct a socio-economic analysis for the dossier.
  • The preferred methodology to conduct the socio-economic analysis of the authorisation application is the cost/benefit analysis.
  • Key elements of a successful authorisation dossier:
    • A specific request with the most elements possible in relation to your activity
    • Transparence and realism of the hypotheses and data as all elements produced will be challenged by the committees or stakeholders
    • The “applied for use” and “non-use” scenarios are essential for the relevance of the socio-economic analysis
