The new Toy Safety Directive 2009/48/EC (TSD) requires a series of safety assessments, including the Chemical Safety Assessment (CSA). If the non-chemical requirements were already enforced in July 2011, the chemical requirements are to be enforced first on 20 July 2013. In 2009, the European Union adopted the new Toy Safety Directive 2009/48/EC (TSD). The Comité Européen de Normalisation or CEN wrote these standards in order for them to be harmonized under the Toy Safety Directive. Official EU Guidance on the interpretation of the Toy Safety Directive 2009/48/EC exists and although non-binding, it has been agreed by a majority of EU Member States.
