Suppliers are expected to establish due diligence processes aligned with the OECD Due Diligence Guidance, provide transparency regarding the smelters and refiners in their supply chains, and support responsible sourcing practices. 

HP conducts annual mineral surveys and reviews supplier-reported information, assesses potential sourcing risks, and engages suppliers to address identified issues through continuous improvement efforts. Where appropriate, we work with suppliers to mitigate risks associated with mineral sourcing and encourage the use of smelters and refiners that have been independently assessed through recognized industry programs, such as the Responsible Minerals Initiative's Responsible Minerals Assurance Process (RMAP). 

We also provide guidance, training, and ongoing engagement to help suppliers meet our expectations and support responsible sourcing throughout the supply chain.
