How We Managed Our Any of our suppliers or sub-suppliers sourcing from the DRC must exclusively source from RMAP conformant refiners Battery Cobalt Supply Chain in 2020 In 2020, our battery cell sourcing was divided into three distinct supply chains for cobalt: Gigafactory Nevada and Fremont external cell sourcing, Gigafactory Shanghai and Fremont in-house cell production. For Gigafactory Shanghai and Fremont in- house cell production, we procure cobalt materials directly from producers that are verified as compliant with Tesla’s Code and with whom we have direct contractual obligations around responsible sourcing per OECD Guidelines. We work with participants along the value chain to shorten the supply chain by eliminating third-party cobalt refiners and by ensuring that Tesla’s material is stored in clearly marked, segregated areas of the plant and is toll processed on lines dedicated for Tesla. For Gigafactory Nevada and Fremont external cell sourcing, where Tesla does not directly procure cobalt materials, cobalt is sourced by our battery cell suppliers from many different countries (listed below). For material originating from the DRC, Tesla’s battery cell supplier and sub-suppliers are required to purchase refined cobalt exclusively from qualified, conformant cobalt refiners as per the Responsible Minerals Assurance Process (RMAP) standards set forth by the RMI. Audits are conducted by third parties approved by the RMI, and an “Active” or “Conformant” classification provides an acceptable level of supplier transparency. Currently, the only suppliers with a “Not Listed” classification that Tesla has a relationship with do not source minerals from the DRC.
