Measures regulating the kind, colour and size of printing on packages and labels and defining the information that should be provided to the consumer: Labelling is any written, electronic, or graphic communication on the packaging or on a separate but associated label, or on the product itself. It may include requirements on the official language to be used as well as technical information on the product, such as voltage, components, instruction on use, safety and security advises, etc.
Example: Refrigerators need to carry a label indicating its size, weight as well as electricity consumption level.
