REACH applies to all substances currently produced in or imported to the EU. They are registered in three phases with data requirements depending on their production volume (substances above 1,000 metric tons per year; substances above 100 metric tons per year; substances above 1 metric ton per year). The implementation of REACH is not limited to registration. Following the registration process, the dossiers that are submitted have to be updated continuously. The risk assessments prepared by the industry are reviewed by ECHA and EU member states competent authorities. These evaluations can result in requests for additional data as well as restrictions or authorization processes. The REACH requirements have to be implemented in the production and business processes. This is intended to ensure the safe handling of chemical substances in Europe
While REACH only applies in Europe, BASF has also set a goal to review all risk assessments worldwide by the year 2020 for substances and mixtures which BASF sells in quantities of more than one ton.
