The symbol "CE" found on children's toys stands for "Conformité Européene," which means European Compliance. The symbol indicates that a toy meets European Toy Safety Directive (TSD) requirements. When toy manufacturers adhere to the TSD, those products can be freely traded in European Union and EFTA member states.
As of August 2014, the most-recent directive, enacted in 2009, required that all toys pass a series of chemical and non-chemical safety assessments. The original mark, "EC," was adopted in 1990 and changed to "CE" in 1993. It is referred to as a CE Marking in all official European documents. The symbol itself may be reduced or enlarged, but its proportions must be maintained and it can be no less than 5 millimeters tall.
