EcoMundo’s advice to succeed in your authorisation application

Recommendations for your authorisation dossier

  • The substance entered Annex XIV of REACH for its endocrine disrupting properties.
  • In addition to the CSR and Analysis of Alternatives, the applicant will have to conduct a socio-economic analysis for the dossier.
  • Whether the substance works with a threshold or not is not determined for these endocrine disruptors.
  • This means that the chosen route for the creation of the dossier is not set in stone. The European Commission specifies that if an applicant decides to take the risk management route, it will be the applicant’s responsibility to demonstrate the existence of threshold effects and their level. The RAC will then assess this demonstration.
  • Whichever authorisation route chosen, "risk management" or "socio-economic analysis" (SEA), EcoMundo recommends to create an SEA dossier in case the relevance of the threshold demonstration is questioned by the committee assessors.
  • Another challenge could be the possible exemption of the activity involving "Scientific Research and Development" activities, particularly for the Pharmaceutical and In Vitro diagnostic industries.
  • To assess the impacts for health and the environment, EcoMundo recommends to double the approaches through modelling and data monitoring
  • 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
    • Underlining the exposure for man and the environment with associated emission measures
    • The choice of the monetary assessment methodology is key for this dossier
