The Trade Tariff Service, a governmental body of the planet Corellia, operated from its offices situated within the Government District of Coronet City, the capital. When the reconstituted Sith Empire launched an invasion of Coronet City during the Battle of Corellia in 3640 BBY, Moff Tarandon suggested to Sith Lord Darth Decimus that he should set up his command post in the Tariff Service's building. Tarandon reasoned that the building had become useless and that enemy troops were more likely to target the neighboring Legislature Building instead. Decimus concurred, and his troops rapidly transformed the building into an Imperial stronghold known as Decimus's Rise. The few remaining officials who were present when the Empire invaded either escaped the building by any means available to them, or swore allegiance to the Empire.
Star Wars: The Old Republic, a video game that came out in 2011, included the Codex entry for Decimus's Rise, which was the first time the Trade Tariff Service was referenced.
