The package comprises three legislative acts establishing a Common Data Platform (CDP) on chemicals, re-attributing technical tasks, and strengthening cooperation among EU agencies, notably the European Chemicals Agency (ECHA).

The objective is to harmonise and streamline how chemicals are assessed across all relevant EU legislation, improving consistency, transparency and efficiency. A key operational change for industry is the creation of the CDP, which will centralise chemical-related data used under EU laws and is expected to become operational within the next three years.

Importantly, companies will be required to notify any studies generating chemical data that they commission to support an application, notification or regulatory dossier submitted to an authority. This includes studies carried out as part of risk or safety assessments under relevant Union legislation. At the time of commissioning, companies must inform the laboratory or testing facility that the study is subject to this notification obligation.

IFRA will continue to keep members informed as implementation of the OSOA framework progresses.
