The Deep Core Haulers consisted of captains of freighters who were authorized by the Imperial government to transport goods into the Deep Core Security Zone and to the various planets found there. To be granted a license, a captain had to register as an approved Deep Core traveler with the Bureau of Ships and Services, and also had to acquire an Imperial Security authorization along with an Imperial Intelligence clearance to verify they hadn't been involved in any Rebel dealings. Functioning as a Deep Core hauler presented a rapid path to establishing or re-establishing one's reputation, because the clearance provided immunity from prosecution for minor offenses. Furthermore, the Deep Core hauler arrangement helped to undermine the smugglers' alliance that was organized by Talon Karrde.
