Supply chain integrity We endeavor to provide safe, high-quality products to our customers and their patients; a commitment that is guided by our company’s purpose and mission. Additionally, the suppliers of our internationally sourced private-label products must agree to the McKesson Supplier Sustainability Principles (MSSP), which cover compliance with applicable laws along with adherence to strict policies on protecting workers, preparing for emergencies, and protecting the environment. Global sourcing and supply chain management Our company-wide values are the foundation of McKesson’s approach to being a responsible corporation. As a trusted organization — one that goes the extra mile to advance our customers’ and business partners’ success — these values are also the foundation of McKesson’s approach to being a responsible steward of international supply chain management. Our Global Sourcing organization is responsible for identifying potential overseas suppliers for our private-label brands. Once suppliers are identified, we begin assessment and qualification processes to determine if these suppliers meet our criteria. Our Global Sourcing teams evaluate suppliers for adherence to Current Good Manufacturing Practices (CGMP) and other regulations, while our Responsible Sourcing teams evaluate supplier conformance to the MSSP. Global Sourcing To support our Global Sourcing program, we have employees in certain countries where our private-label products are manufactured by third party suppliers. These McKesson employees focus on product quality, supply chain and logistics, and sourcing; and perform product inspections and audits during factory visits. Suppliers must complete assessments and audits covering CGMP and our own responsible sourcing criteria, outlined in the MSSP in accordance with our protocols. Our Global Sourcing team may only procure items from suppliers after the supplier fulfills our standards and are added to our approved supplier list. Furthermore, new internationally sourced private-label products undergo product qualification processes, which can involve using benchmark products, developing inspection criteria and private- label artwork to help ensure compliance with brand guidelines and regulatory obligations. We have in-house licensed customs brokers for shipments bound for the U.S. that enable the importation of products into the U.S. Our company- wide values are the foundation of McKesson’s approach to being a responsible corporation.
