Green procurement activities

To partners delivering parts and materials to Hamamatsu Photonics K.K.

As interest grew on the part of society with respect to the environment and international environmental regulations were beefed up, Hamamatsu Photonics decided to formulate "Green Procurement Guidelines" and "Green Procurement Management Standard for Chemical Substances", and to promote involvement in environmental concerns. We ask our business partners for their understanding and cooperation in this effort, and to conform to these guidelines and standards when delivering products and materials to us.
