Corporate Social Responsibility:
For Customers, for the Environment and for Society

Quality of TANAKA

Delivery of "good items" to customers is a principle of Tanaka Kikinzoku Group.
In addition to the quality of products, we also pay attention to human rights, the environment, health and safety, ethics and other issues in the process of producing products.

Quality Management Activities Based on QMS

To supply safe and secure products that satisfy customers in a continuous manner, we have established and operated a quality management system (QMS) based on ISO 9001. We also review the effectiveness of the QMS and improve the system so that we can promptly respond to ever-changing customer demand on quality and meet the trust and expectation of customers. In addition, requirements of IATF16949, a quality management system for the car industry that requires a sophisticated quality management structure, are reflected for the continual improvement of the QMS.

Realization of CSR Activities That Satisfy Customers

○Efforts to Enhance the Reputation of Our CSR Activities
Tanaka Kikinzoku Group performs business activities in consideration of CSR issues including human rights, the environment, health and safety and ethics, and complies with Tanaka Kikinzoku Group Code of Conduct and Tanaka Kikinzoku Group Standards of Conduct, which are in line with the spirit of the RBA Code of Conduct*1, to meet the demand of customers in the world as well as social expectation. In fiscal 2017, we implemented a factory audit by a third-party institution accredited by RBA, as well as a self-audit, and took corrective actions. In addition, we call on approximately 200 suppliers to comply with the RBA Code of Conduct and continuously conduct the survey of their status of compliance and feeding back of the results.
In the assessment by EcoVadis*2, a supply chain CSR assessment agency, concerning the environment, occupational health and safety, ethics and supply chain, we were awarded a silver rating in September 2017.

○Efforts for Responsible Procurement of Minerals
We promote conflict free procurement of raw materials. To this end, Tanaka Kikinzoku Kogyo K.K. has established its Responsible Mineral Management Policy to control risks related to the transaction of conflict minerals, namely gold, tantalum, tungsten and tin, in the procurement of raw materials and to avoid any procurement involving violation of human rights, terrorism, money laundering, illegal transactions, inhuman acts and armed groups. With respect to the transaction of gold, we obtained certification after an audit by a third party based on the LBMA* Responsible Gold Guidance, and have renewed the certificate every year since 2014.
