Letter of Access management

The European chemicals legislation REACH requires chemical substances that are placed on the EU market to be registered with the chemicals agency ECHA; and pursues the principle “one substance, one registration”.

All registrants of the same substance are obliged to the Joint Submission and must use the same data to avoid unnecessary animal testing.

The access right to the data for the participants in the Joint Submission is regulated via the so-called “Letter of Access” (LoA). By signing the Joint Submission Agreement, the co-registrant agrees to contribute to the total cost of registering a particular substance. These costs consist of the data, dossier and administrative costs and are reflected in the LoA fee. After payment of the LoA fee, the co-registrant receives the agreed files necessary for registration, the token allowing him to access the Joint Submission and the LoA document certifying the data access rights.
