The Copper Mark standards include

• The Risk Readiness Assessment Criteria Guide: also known as the Copper Mark Criteria for Responsible Production, this is a set of 33 criteria that serve as a common standard of reference for environmental, social, and governance practices in mineral supply chains. This is the main standard, the successful completion of which results in The Copper Mark, The Molybdenum Mark, The Nickel Mark, and / or The Zinc Mark.
• The Joint Due Diligence Standard for Copper, Lead, Molybdenum, Nickel and Zinc: third-party assessed as aligned to the OECD Minerals Guidance, the Standard takes into account the risk profile of copper, lead, molybdenum, nickel and zinc (the principal covered metals) supply chains and is designed to enable effective due diligence for producers and/or traders of these metals. The standard is included in the second part of Criterion 10 of the full risk readiness assessment criteria guide.
• The Copper Mark Chain of Custody Standard: a voluntary add-on option to an assessment against the Copper Mark Criteria. It defines the requirements for a system of control and transparency for copper-containing products that move through a supply chain.
