The Green Line is a line granted to companies holding an Authorized Economic Operator certificate, where neither document checks nor inspections are conducted. Goods related to the customs operations of AEO companies mostly go through the green line. Goods passing through the green line mean they are cleared from customs without inspection. After obtaining the customs declaration registration for the goods, they can be released without being subjected to any control.

OKSB (Approved Person Status) is a customs status that grants certain facilities in customs operations to companies that fulfill their customs obligations, keep their trade records according to generally accepted accounting principles, have financial sufficiency, employ a certain number of people, and have a certain foreign trade performance.
