The IGSA was incorporated in 1928 as the Idaho Traffic Association with the sole charge to fight for fair transportation rates for the Idaho agricultural industry. In its early years, iconic industry members such as J.R. Simplot served as President and the Association held annual conventions in Boise, Idaho Falls and Sun Valley, Idaho. As the needs of the members evolved so did the name of the Association. In 1945, the Association changed its name to the Idaho Potato & Onion Shippers Association only to change it again seven years later to the Idaho Shippers Association. In 1960, the name was changed to the current Idaho Grower Shippers Association (IGSA). Nearly 100 years after the first annual meeting of its members, the IGSA continues to facilitate the accomplishment of common goals within the Idaho potato industry.
