Manufacturers are to ensure compliance with those Ecodesign requirements that are applicable at the time of the placing on the market of an individual unit. However, a number of obligations are to be fulfilled by manufacturers prior to the placing on the market of individual products such as carrying out the conformity assessment, issuing the EU declaration of conformity and affixing the CE marking on the product.
When more than one piece of EU legislation apply to a product and require the issuing of EU declarations of conformity, the manufacturer can fulfil its commitment via an unique EU declaration of conformity and can also establish a consolidated technical documentation.
Disclaimer: Please note that the European Commission cannot provide a legally binding interpretation of the EU legislation, as this is the sole competence of the European Court of Justice. Any remarks from the European Commission services are without prejudice to the position the Commission might take should related cases arise in a procedure before the Court of Justice.
