In Guardian’s supplier diversity program, a diverse supplier is a for-profit enterprise that is owned, controlled and operated by (1) minority group members (e.g., Hispanic American; Native American; African American), (2) women, (3) U.S. military veterans, or (4) lesbian, gay, bisexual, or transgender individuals. For this purpose, “owned” means that the enterprise is at least 51% owned by such individuals (if the entity is publicly owned, at least 51% of the stock must be owned by one or more such individuals), “controlled” means that such persons actively exercise the power to make policy decisions for the enterprise, and “operated” means that such persons are actively involved in the daily management of the business.

How to participate

In order to participate in our program you must be certified by one of the following:

  • National Minority Supplier Development Council (NMSDC)

  • Women's Business Enterprise National Council (WBENC)

  • National Gay & Lesbian Chamber of Commerce (NGLCC)

  • National Veteran-Owned Business Association (NAVOBA)

  • Certification from select federal, state, and local government agencies

  • Small Business Administration 8(a) Program (SBA)

Interested diverse suppliers should send a copy of their certification(s) to Guardian at Once submitted, diverse suppliers will receive email confirmation of Guardian’s receipt of their certification materials. Their names will then be vetted through our certification process and made available to Guardian’s sourcing team for possible inclusion in future procurement activities.

Please note that submitting this information is not a guarantee of business and that contracts are not awarded based on diverse certification status alone. All vendors, whether certified as diverse suppliers or not, must undergo additional qualification by Guardian’s operating business units and/or sourcing team for the best possible fit with respect to Guardian’s business needs.
