A Jom-trader was a kind of itinerant merchant on the planet Utapau. When Luke Starkiller noticed another landspeeder in the distance as he traveled from the Lars homestead to Mos Eisley, he dismissed his sighting of the Gray Tusken, an Imperial spy, as a "jom-trader".
On arrival in Mos Eisley, he noticed that the other landspeeder was a shiny black, a Tusken landspeeder, and he immediately became concerned.[1]
