In 2012, the Securities and Exchange Commission adopted rules implementing the conflict minerals provisions of the Dodd-Frank Act (the “Conflict Minerals Rules”). This requires public companies to annually disclose information about whether the products they manufacture or contract to manufacture, for which 3TG Minerals are necessary to the functionality or production of those products, contain 3TG Minerals that originated in any of the Covered Countries. If so, information about the source and chain of custody of those 3TG Minerals must also be disclosed.


This Policy applies to McKesson’s employees who manage relationships with suppliers of products to McKesson, its subsidiaries, and its affiliates.  


Our supply chain is highly complex, and our manufacturing process is significantly removed from the mining, smelting and refining of 3TG Minerals. As a result, we expect that all of our suppliers will partner with us to provide appropriate information and conduct necessary due diligence in order to facilitate our compliance with the Conflict Minerals Rules.  We are committed to working with our suppliers to educate them about these issues and the steps that they can take to increase the transparency of the supply chain.

McKesson suppliers are expected, upon request, to:

  • Identify the steps in the supply chain through which 3TG Minerals are introduced, and undertake all due diligence efforts necessary to identify the smelter, refiner and/or mine from which 3TG Minerals originate. This may include requiring direct or indirect suppliers to our suppliers to cooperate in diligence efforts and to provide any information necessary to facilitate our compliance efforts with respect to the Conflict Minerals Rules;
  • Supply us with timely and accurate information regarding the source of 3TG Minerals in our supply chain and the steps that have been undertaken to determine whether such products and materials are DRC Conflict Free, including whether the source has been verified by a recognized, independent third party; and
  • Advise us promptly of any determination that any products or materials in the supply chain are not DRC Conflict Free.

We evaluate our relationship with our suppliers on an ongoing basis.  Although the existence of the Conflict Minerals Rules is no guarantee that our suppliers will be in compliance or cooperate with our requests for additional information, the disclosure requirement is mandatory.  If a supplier has failed to comply with this Policy, or if we determine that a supplier’s efforts are deficient, we will take appropriate action, which could result in terminating our relationship with the supplier and securing a replacement supplier who will comply with this Policy.

McKesson employees are always obligated to report instances of non-compliance with our policies.  To report potential violations of this Policy, employees should:

  1. Contact their Business Unit Compliance Officer or Business Unit Lawyer;
  2. Send an email to conflictminerals@mckesson.com; or
  3. Call McKesson’s Integrity Line at 1-877-625-4625.  Local toll-free numbers for locations outside the U.S. are listed at integrity.mckesson.com. 

McKesson prohibits retaliation against those who, in good faith, raise concerns or ask questions regarding matters of ethics or legal compliance or participate in an investigation.

Nothing in this Policy is intended to modify or otherwise limit our contractual or legal rights.
