Responsible Mineral Procurement
This document sets out Rigaku’s stance on responsible mineral procurement.
See Responsible Mineral Procurement Policy
The Dodd-Frank Wall Street Reform and Consumer Protection Act, commonly referred to as Dodd-Frank, enacted in 2010, served as a starting point for the world to take more interest in “Responsible mineral procurement”. Tin, tantalum, tungsten, and gold (“3TG” for short) are called “conflict minerals”. Especially 3TG mined in the Democratic Republic of Congo (DRC) and its neighboring countries have the risk of providing funds to armed groups, etc. Section 1502 of Dodd-Frank enacted in 2013 obliged SEC (Securities and Exchange Commission) registered companies to conduct an annual survey/report about usage of these minerals which were mined in DRC and its neighboring countries and fund armed groups or anti-government forces. In 2021, Conflict Minerals Regulation came into full force across the EU. The EU legislation’s scope is not only DRC and its neighboring countries but also the other countries or areas considered to be conflict-affected or high-risk. As represented by this legal development, target minerals are not limited to 3TG and the necessity and importance is increasing of responsible mineral procurement based on international trends which consider the risks of general human-rights violations including child labour or corruption.
The Rigaku group of companies works to achieve responsible mineral procurement through the whole supply chain. We establish this Responsible Mineral Procurement policy to clearly explain our stance.
Declaration of Partnership Building
By committing to this Rigaku group declares that it focuses on coexistence and co-prosperity of the entire supply chain and disclose “Declaration of Partnership Building” to the public, which is promoted by the cabinet members of related Japan ministries and agencies.
We strive to increase the value added throughout the supply chain by reaching out, comply with desirable trade practices, and enforce the relationship with business partners.
