Apple Inc. has reached what it’s calling a milestone in supply-chain transparency, saying it’s now auditing 100 percent of its suppliers for the use of conflict minerals linked to violent militia groups in the Democratic Republic of the Congo.

The iPhone maker has been working since 2010 to remove minerals connected to these groups from its supply chain, and while it isn’t yet declaring its products totally conflict-free, the company said all of its 242 smelters and refiners of tin, tantalum, tungsten and gold are now subject to third-party audits. That figure is up from about 88 percent at the end of 2014 and 44 percent in 2013, according to an annual filing the company will release Wednesday.
