Apple has committed to using conflict-free minerals and will require suppliers to use only verified elements by naming and shaming companies.
The company’s latest annual Supplier Responsibility Report listed 104 suppliers that are not known to be verified by the Conflict-Free Smelter Program (CFSP).
Apple also listed details of 59 companies that are CFSP compliant, and a further 23 firms that have agreed to participate in the CFSP audit.
The company said last month it confirmed third-party auditors had verified all active, identified tantalum smelters in its supply chain as conflict-free.
“We’re pushing our suppliers of tin, tungsten, and gold just as hard to use verified sources,” added Apple.
“The smelter list is just one example of how we work hard to be more transparent, which we believe is critical to improving conditions for workers around the world.”
