Product safety – REACH declaration

Declaration on the Regulation EC1907 / 2006 concerning the Registration, Evaluation, Authorization and Restriction of Chemicals (REACH Regulation)

DIENES Werke GmbH & Co. KG is aware of its responsibility within the supply chain and complies with all guidelines required by REACH to ensure a high level of product safety.

DIENES does not manufacture any substances or preparations affected by REACH, nor do we import any. Therefore, in terms of REACH, we are a downstream user in the supply chain, are not subject to any registration obligation and do not have to prepare any safety data sheets.
All products delivered to you by DIENES plants are classified as articles according to the REACH regulation (Art. 3, definition) and are therefore not subject to registration. There are also no substances released from our delivered products under normal or reasonably foreseeable use according to REACH regulation article 7.

We have requested our suppliers to inform us immediately, in accordance with the notification obligation from the REACH Regulation Article 33, if substances of very high concern classified by the ECHA according to the candidate list are contained in the product now or in the future. Furthermore, we will also inform you about relevant changes caused by REACH within the products, their delivery capability as well as the quality of the parts/ products supplied by us to you within the scope of our business relationship and coordinate suitable measures with you in individual cases.

Our development engineers and production staff therefore leave nothing to chance in order to guarantee service life and safety in your ongoing production.
