Technical Equivalence will be one of the next challenges for the Biocides Industry

Technical Equivalence must be demonstrated at product authorisation stage if the source of the active substance is different from the reference source. Getting an alternative source recognised as technically equivalent is not an easy and straightforward process. Decisions by ECHA on technical equivalence are subject to review by the Board of Appeal. 

This webinar provided a regulatory and legal overview of this complex matter and identified the steps to a successful Technical Equivalence application and strategic considerations on remedies available. It covered the following points: 

  • When is it needed?
  • Required information
  • Tier I or Tier II?
  • Timelines
  • Legal remedies
