UNI-PASS is an e-Customs system which provides swift customs clearance, increases government revenue, connects various government and private parties to facilitate international trade and ultimately contributes to the economic development of Korea and many other countries.

The UNI-PASS is divided into 5 main components: Customs Business, Integrated Risk Management, Single Window, IT Management, and Customs Administration. Each component has various sub-systems that when put all together provides a fully functional e- Customs system. Further more by applying international standards the system is compatible to any customs business environment, prepared to share information with other customs authorities.


Since the 1960s, Korea has experienced a dramatic increase in trade volume and international passengers. With limited available resources, the KCS(Korea Customs Service) was looking for a way to overcome these difficulties by innovative means. The solution was to re-engineer, optimize and standardize the customs procedures in order to automate the existing practices and apply state of the art IT technology that resulted in development of UNI-PASS system by the KCS and CUPIA. First developed as a simple trade statistic system in 1974, UNI-PASS has experienced various innovations while incorporating the Single Window portal in 2006, and in 2016 the KCS successfully finished implementing the 4th Generation UNI-PASS system.

Implementation of UNI-PASS involves enhancing regulations, business practices and organization structure by applying automation techniques. These enhancements are consisted of implementing the following 6 areas.

Customs Business Component

Composed of modules for the automation of customs administration, it includes business procedure modules (cargo & clearance management etc.) and non-business procedure modules (investigation, audit etc.)

Integrated Risk Management Component

Assists and supports the Customs Administration component with modules such as the Customs Data Warehouse(CDW) and Integrated Risk Management(IRM) module etc.

Single Window Component

Provides the public users with modules such as the Single Window portal and G2G data exchange module that lets them handle customs clearance process without visiting the customs office.

IT Management Component

Controls and administrates the overall e-customs system to prevent any system failures. It consists of modules such as the EWACS and IT Resource management module etc.

Customs Administration Component

Supports the Customs Administration process and provide non-business procedural functions such as Knowledge management and Performance management.

International standards

The UNI-PASS system is based on international standards such as WCO DM 3.0. UN codes and has applied international recommendations such as the Revised Kyoto Convention and the WCO SAFE Framework. Based on such foundations, the system has been exchanging customs data with other countries.
