We began as Independent Commodity Trading, a company focused on connecting fuel suppliers with clients through brokerage and distribution. As our expertise and network grew, we recognized the importance of logistics in delivering real value — and expanded our operations to manage transportation between suppliers and customers.

To strengthen this capability, we established Harper Fuel Services, dedicated to providing efficient and reliable fuel supply for domestic markets. Through hard work, consistency, and a commitment to operational excellence, we earned a reputation for delivering quality products and dependable service. This foundation allowed us to secure state and federal fuel supplier licenses and build direct relationships with refineries and terminals across North America.

As our business evolved, we invested in rail infrastructure — acquiring a modern fleet of railcars and establishing long-term partnerships with major North American railroads, supported by our subsidiary in Mexico. Today, all our operations are unified under Oleum Group, reflecting our growth from a fuel broker to a fully integrated energy and logistics company. Our mission is to deliver energy and logistics solutions that move the world — with a primary focus on North America and a vision that extends globally.
