If you are an importer or distributor and you add your own name or mark to a construction product, you must be aware, that your role changes.
Under the law, you become a manufacturer, and you must thus meet all the obligations of a manufacturer.
This means that you must draw up the declaration of performance and affix the CE marking to the construction product, and that you become responsible for ensuring the factory production control of the construction product in accordance with the Construction Products Regulation and the relevant harmonised standard.
If the initial testing and calculation has already been carried out for the product in accordance with the harmonised standard, it is possible to use the test results and documentation. In order to do so, you need to obtain a permission from the manufacturer.
