Chesar can support registrants with the TCC requirements on CSRs also in absence of exposure assessment

08 June 2022

Since March 2021 ECHA’s technical completeness check has been extended to CSRs. We would like to draw your attention to two key requirements for technical completeness: 

  • Each use reported in the IUCLID dossier must have a corresponding exposure scenario in the CSR.
  • Each contributing activity per reported use in IUCLID must have a corresponding contributing scenario in the relevant exposure scenario in the CSR.

Chesar guides users in carrying out a chemical safety assessment per reported use and contributing activity. In case an assessment is not needed for a use or contributing activity, a justification for the absence of the assessment should be reported in the CSR. Information on how to report such justification in a standard location in the CSR (to ensure that it will be identified during the manual CSR TCC) can be found in the new FAQ recently published on the Chesar website.

To meet the CSR TCC requirements Chesar users are invited to read carefully also the following FAQs: 

  • How can I ensure the synchronisation of my exposure scenarios in the CSR generated by Chesar with the use description in IUCLID? Which option shall I choose in Box 4 of Chesar?
  • I am a lead registrant and I need to generate both an own CSR and a joint CSR. How can I use Chesar to ensure that the use description in IUCLID and in the CSR are aligned and consistent with the exposure scenarios?
