Joint Due Diligence Standard for Copper Lead Nickel and Zinc
The Joint Due Diligence Standard was developed collaboratively by the Copper Mark (CuMark), the International Lead Association (ILA), the International Zinc Association (IZA), the Nickel Institute and the Responsible Minerals Initiative (RMI).
The Standard enables companies in the supply chain to comply with the London Metal Exchange Responsible Sourcing requirements, and covers risks associated with conflict and human rights abuses in mineral supply chains. The Standard is designed to enable effective due diligence for producers and traders. It builds on existing standards and it intends to provide flexibility for multi-metal producers which extract both primary and secondary (by-product) minerals at their production sites.
