ECHA | New advice for using read-across

ECHA’s advice helps companies create robust and complete read-across adaptations for their substances, including those of unknown or variable composition, complex reaction products or biological materials (UVCBs). It covers changes to the REACH annexes that started to apply in January 2022.

Helsinki, 6 May 2022 – Companies are required to adequately justify and document the use of grouping and read-across in their registrations. They need to include robust study summaries for each study performed on a source substance which is used to provide information for the target substance. Their registrations also need to contain justifications and evidence for the read-across hypothesis.
