Supplier code of conduct

Standards of the supplier code of conduct


A message from our supply chain

Black Hills Corp. is committed to safety, diversity, environmental leadership, social responsibility and ethical business practices. These fundamental values ensure that the decisions we make today are the right decisions for tomorrow. We expect our suppliers of goods and services to adhere to these fundamental values and apply them to how they do business.

Our Code of Business Conduct and the Supplier Code of Conduct describes our expectations in more detail. Suppliers should educate their employees, agents and subcontractors so that they understand and comply with these codes as well as their own ethics and compliance guidelines. Noncompliance can alter Black Hills Corp.’s business relationship with a supplier, potentially resulting in termination of the business relationship.

I thank each of our suppliers, vendors and contractors for their commitment to these values. Upholding the highest standards of ethical, social and sustainable conduct is at the core of our relationship.

Vice President, Supply Chain
