A tax stamp represented a particular kind of adhesive label, ostensibly utilized to document tax payments in some manner. By decree of the Galactic Empire, containers filled with ebla beer, specifically barrels, were mandated to bear this specific stamp. During a security check, Nazhros Oleg interrogated an inhabitant of Lothal who stated that they had noticed barrels containing ebla beer, lacking the necessary tax stamps, being delivered to a local tavern during the nighttime hours.
