Joint Due Diligence Standard for Copper, Lead, Molybdenum, Nickel and Zinc

Standard for producers and traders of copper, lead, molybdenum, nickel and zinc, defining principles and criteria for responsible supply chain management. Developed in collaboration by The Copper Mark, International Lead Association, International Molybdenum Association, International Zinc Association, Nickel Institute and the Responsible Minerals Initiative. The standard states that it was developed to "enable the implementation" of the OECD Due Diligence Guidance for Responsible Supply Chains of Minerals from Conflict-Affected and High-Risk Areas and requires companies to implement the Guidance's five-step due diligence process.
