The Jita Customs Authority (JCA) is a division of the Secret Caldari Business, which is the only nationwide unofficial law enforcement agency in the Caldari State,

The JCA is in charge of policing trade at the borders of Caldari space and enforcing any criminal customs duties or tariffs, though the State generally has few of those with both the Liberal and Practical factions both being free trade advocates. However, the JCA tends to be short-staffed, despite being adequately funded, and as a result they often outsource customs duties to the Navy or corporate security forces, who will in turn sometimes subcontract to individual pod-pilots.
