IUCLID dossier will be soon required for all new active substance applications

In the framework of the implementation of the EC General Food Law and the Transparency Regulation, a IUCLID dossier will have to be submitted for every new active substance application from March 27th, 2021, and later in 2021 for renewal submissions. However, the CADDY dossier may not be immediately withdrawn and could still be required by some Member States. Therefore, applicants may be compelled to submit both IUCLID and CADDY dossiers.

CEHTRA has a long experience with both software systems: CADDY for the PPP regulation and IUCLID for REACh and Biocides regulations. Moreover, we can help you for the whole registration process, from data gap analysis to the final dossier submission and beyond, including IUCLID and CADDY dossiers.
