On October 29-November 1, 2018, CLDP, in partnership with the Pakistan Regional Economic Integration Activity (a private sector implementer for USAID), the U.S. Commercial Service, U.S. Customs and Border Protection, and Korean Customs Service, led a delegation of officials from the Pakistan Customs Service, Ministry of Commerce, Ministry of Planning, Development, and Reform, and other stakeholder agencies on a study tour to Daejeon and Seoul, South Korea. Pakistan recently passed legislation regarding its single window, a required element under the World Trade Organization’s Trade Facilitation Agreement, and has been developing its platform. The study tour focused on the three different Korean single window projects run by different ministries, the inter-agency process to harmonize data required for clearances, and port community systems. The study tour provided non-customs agencies with better insight into the advantages of single window and helped the Pakistan Customs software engineers understand how to build an inter-agency and user-friendly platform. Following this study tour, CLDP will work with USAID to determine next steps, including a possible U.S. port visit.
