Green Procurement & SDS

To manage environmentally harmful substances, we have stipulated a list of prohibited chemical substances, and check that prohibited substances are not contained in the materials and indirect materials we purchase.

In April 2017, we added these prohibited substances to our List of prohibited substances (Rev.3). These changes were made in order to reflect revisions to national and international law (Act on the Evaluation of Chemical Substances and Regulation of Their Manufacture, RoHS2.0, REACH, Conflict Minerals etc.) and to add information regarding frequently requested substances.
