Best Buy Fiscal Year 2022 ESG Report | 72 Conflict minerals . The Democratic Republic of the Congo (DRC) and its neighboring countries have reserves of tin, tantalum, tungsten and gold (known as 3TG), all of which are commonly used in the manufacturing of many consumer products. Occasionally, these minerals are illegally sourced and traded by armed groups who are responsible for human rights violations. As such, 3TG are known as “conflict minerals.” At Best Buy, we are committed to working toward a conflict-free supply chain for our private label products. We align our conflict minerals program with the Organization for Economic Cooperation and Development (OECD) Due Diligence Guidance for Responsible Supply Chains of Minerals from Conflict-Affected and High-Risk Areas, an internationally recognized framework. Despite advances in supply chain transparency and traceability capabilities, it remains a challenge to identify, with certainty, the smelters, refiners and recyclers in our private label supply chain. Training our direct suppliers and auditing their performance are keys to addressing this. In FY22, 100 percent of our suppliers received training specific to conflict minerals, and since 2017, we’ve audited the due diligence efforts of 47 of our suppliers who use 3TG.
