In your daily life, while using and handling items such as mobile phones, music players, toys, cables, and other electronic equipment or machines, you might have noticed two letters, CE, on these products. Forasmuch as this is a mark applicable to products traded within the European Economic Area (EEA, the 27 Member States of the European Union [EU] and 3 countries of the European Free Trade Association [EFTA]: Norway, Iceland and Liechtenstein), consumers living in these areas may be familiar with it as it can be found in almost every product. But yet many people may wonder why it is applied to products or what does it serve for.
