Apple has established its own supplier’s code of conduct, which begins “Apple is committed to ensuring that working conditions in Apple’s supply chain are safe, that workers are treated with respect and dignity, and that manufacturing processes are environmentally responsible,” and also for some time has published annual audits of its suppliers. Apple’s website organizes this information in a section labeled “Supplier Responsibility at Apple.” The following documents can be found there.
