About TDK | Procurement

Green Procurement Activities

TDK is promoting procurement of products with reduced environmental impact (environmentally-friendly products) with the objective of supplying products with minimal environmental impact.

As awareness concerning environmental preservation rises, corporate and production activities that take the environment into consideration are becoming more important.

To ensure the proper promotion of such activities, TDK conducts surveys of supplier environmental and other activities, reviews information on substances of concern used in procured goods, and conducts surveys of green procurement through the latest TDK Green Purchasing Standards.

Green procurement is not possible without the cooperation of suppliers. Accordingly, we request your understanding of TDK's policies and your support and cooperation.
