The National Association of Shell Marketers (NASM) is a brand specific trade association which represents the interests of those companies which have wholesale contracts with Shell Oil. NASM was founded in 1974 by Texaco petroleum marketers as a non-profit organization, and was expanded to include marketers of Shell petroleum products in 1999. As the conversion from Texaco to Shell retail outlets progressed, the Association evolved into an exclusively Shell marketer organization. NASM represents Shell wholesale marketers with retail locations in nearly every state in the U.S., and over 120 suppliers of goods and services to the industry.
