Most importantly, you know us for their people and their way of doing business. Their basic values and traditions have remained unchanged for more than 118 years: showing their customers the utmost courtesy and respect; conducting business ethically; and, putting you and your needs first—always. These are the enduring Riddle family values that ensure your continued satisfaction, and that have helped us to remain a leading global processor and merchant of graphite and carbon for well over a century.

Three simple goals, each focused on satisfying the needs of their customers, drive their business. They strive to be increasingly creative in carbons, to be continually global in service, and to respond quickly to every customer’s needs.
