Our principles and approach to corporate responsibility

At Ardent Mills, corporate responsibility is a process of continually improving our standards, our actions and our processes. Ardent Mills was founded by companies with a long legacy and reputation for ethical business. That legacy continues with Ardent Mills today.

In line with our policies, we do not accept or support the use of illegal, abusive or enforced labor. The issue is challenging and we alone cannot solve this complex problem. We believe it is essential that all parties in our supply chains work together to support rural livelihoods, raise incomes and ensure children and adults are not subject to these conditions. We work hard to provide all of our own employees with an equitable, safe and supportive work environment providing competitive wages and the rights to join a union and voluntarily negotiate, and we expect the same from our suppliers.

Our Code of Conduct outlines our company’s ethical and compliance standards for conducting business throughout the world.

In addition to our Code, Ardent Mills is committed to operating responsibly across the markets we serve as we pursue our goal of nourishing what’s next and providing innovative and nutritious grain-based solutions. We are working to accomplish this by focusing on:

  • Working to earn trust every day, always operating with reliability and integrity.
  • Serving others with understanding, respect and care.
  • Operating with simplicity, clarity and transparency, removing barriers and letting people do what they do best.
  • Ensuring the safety of our products and people; doing what’s best to create the safest environment now and for the future.
Put together, our goal is to enhance the quality of life and standard of health of people.
