Responsible Supply Chain

Western Digital is committed to advancing its corporate social and environmental responsibility (CSER) within our internal operations and with our global suppliers.  We continue to be an active member of the Responsible Business Alliance (RBA) and to subscribe to the RBA Code of Conduct.  As part of our commitment, and as a condition of RBA membership, we require global production parts (PP) suppliers and contract manufacturers (CMs) that support the manufacture of Western Digital products (including WD, SanDisk, HGST and other brands) to meet the following requirements:

  • Commit to and have policies and programs in place for complying with the RBA Code of Conduct and demonstrate that they have implemented an effective process to communicate the Code's requirements to their next tier suppliers.
  • Register for RBA Online and complete an RBA self-assessment questionnaire (SAQ) for the facilities that support Western Digital products.
  • Authorize Western Digital to access their RBA facility SAQs that they've uploaded to RBA Online and any Validated Audit reports for their facilities that support the manufacture of Western Digital products.

Additionally, Western Digital requires major PP suppliers and contract manufacturers to also meet the following additional requirements:

  • Undergo an RBA Validated Assessment Process (VAP) Audit every two years and implement corrective action plans for any findings in accordance with RBA timelines.
  • Obtain certification to the most updated revision of ISO 14001 (Environmental) and OHSAS 18001 (Occupational Health & Safety), or ISO 45001 Management System standards.

Policy Regarding Conflict-Free Minerals
Western Digital strongly disapproves of the violence, unsafe working conditions and child labor in the Democratic Republic of Congo (DRC) and adjoining countries and is committed to supporting responsible sourcing of conflict minerals (gold, columbite-tantalite, also known as coltan, cassiterite, wolframite, or their derivatives tin, tantalum or tungsten (collectively "3TG")) and cobalt from the region. Western Digital expects its suppliers to supply materials to Western Digital that are "DRC conflict-free." This means (1) any 3TG necessary to the functionality and production of supplied materials do not directly or indirectly finance armed groups through mining or mineral trading in the DRC or an adjoining country, or (2) any 3TG in supplied materials are from recycled or scrap sources. Western Digital also expects its suppliers to responsibly source cobalt from the DRC and adjoining countries and other conflict-affected and high-risk areas. We further expect our suppliers to adopt policies with respect to 3TG and cobalt in support of this policy and, throughout the supply chain, to require their suppliers to adopt similar policies.

Due Diligence Program
We have established and maintain a responsible supply chain due diligence program designed to ensure responsible sourcing of 3TG used in our products.  This includes ongoing communication and engagement with our global production parts suppliers to ensure sustained due diligence in the sourcing of minerals used in our products.  We are also active members of the Responsible Minerals Initiative (RMI) and we participate in various working groups dedicated to advancing responsible minerals sourcing.  More information about RMI and its programs is available at:
