Responsible Minerals Sourcing

Hamamatsu Photonics recognizes that problems of minerals concerning tantalum, tin, tungsten, and gold, etc, including human rights abuse such as child labor, environmental destruction, and source of funding for groups involved in inhumane armed acts, are one of serious social issues throughout the supply chains for minerals from conflict-affected and high-risk areas. From Cooperate Social Responsibility (CSR) viewpoint, we set our fundamental policy claiming to contribute solving such problems, and are committed to promote the following measures with our business partners.

<Fundamental Policy of Responsible Minerals Sourcing>

We will

  • promote to procure minerals solely from smelters certified as conflict-free under the Responsible Minerals Initiative(RMI*).
  • establish our supply chain management framework compliant with OECD due diligence guidance.
  • carry out the corrective action measures promptly to reduce the risks if identified. Especially, we will examine the concerns if customers pointed out, and do further actions such as survey to our suppliers.

Framework for Responsible Minerals Sourcing

Hamamatsu Photonics has been building our framework for responsible mineral sourcing compliant with OECD due diligence guidance. While we regularly share the status and responding measures to the matters at the Hamamatsu Photonics' Headquarters Environment Committee chaired by a managing director, the survey to business partners is led by the Headquarters Product Assessment Subcommittee with the related departments such as procurement.

Surveys for Responsible Minerals Sourcing

Hamamatsu Photonics conducts surveys of minerals using the reporting templates published by the RMI throughout the supply chains. Based on the results, we conduct its evaluation and do further investigation to business partners if necessary. Meanwhile, we will continue to respond requests from customers appropriately with introducing information database system to support relating operations such as managing survey results and making answers.
