Purchasing and Procurement
Since establishing the Green Procurement Guidelines in FY2003, the Teijin Group has continued to confirm whether suppliers who provide specified substances are operating an environmental management system, and, if not, to request that those suppliers put such a system in place. Furthermore, since FY2007, our green procurement standards have been posted on our website (in Japanese and English) to ensure the full awareness of our suppliers.
Furthermore, the Teijin Group Chemical Substance Self-Imposed Control Guideline was established in FY2004 aiming for not only recognizing the status of environmental management in suppliers, but also controlling chemicals and minimizing risk in the Teijin Group´s business activities. We conduct the management of chemicals based on the degree of risk.
We are also focusing on the management of hazardous substances found in raw materials that may have become included in our products, and strengthening our controls on chemical substance purchasing, such as those relating to substances specified in the RoHS regulations and the Law Concerning the Examination and Regulation of Manufacture, etc., of Chemical Substances. We have listed prohibited substances including those prohibited in principle on our website in Japanese and English to ensure that suppliers are fully aware of these substances.
Green Procurement Guidelines
These refer to a group of substances that are prohibited to be used under any international treaty or domestic law. Needless to say, the Teijin Group will not procure such chemicals, nor will the Group procure items containing any of such chemicals in order to support its business activities, including unintentional procurement of such items.
Furthermore, we request suppliers to verify that no prohibited substances are contained in the materials they supply. In addition, substances prohibited by the domestic laws of the countries where Teijin Group companies are located are subject to the same laws.
This category contains substances designated in the POPs Treaty, Class 1 specified chemicals under the Law Concerning the Examination and Regulation of Manufacture, etc., of Chemical Substances, substances prohibited to be manufactured under the Industrial Safety and Health Act, Japan, etc.
A group of substances subject to control or similar regulation under international treaty or law.
We require examination of such substances by expert staff of the Teijin Group and approval of the head of the business group.
This category contains Class 2 specified chemicals under the Law Concerning the Examination and Regulation of Manufacture, etc., of Chemical Substances, EU/RoHS Directive substances, high-risk endocrine disrupting chemicals, etc.
