The evaluation phase involves a thorough assessment of the information provided in the registration dossier. ECHA and member states evaluate the data to verify the safety of the substances. There are two main types of evaluation: dossier evaluation and substance evaluation. Dossier evaluation focuses on compliance checks and testing proposals, while substance evaluation assesses whether a substance poses a risk to human health or the environment. This step is vital in identifying any data gaps or concerns that may require further investigation.
