Amid the expansion of the global trade and international production processes, demand for trade information and documents are expanding accordingly. Utilization of trade documents is not just confined in national level, but it is also applied to international level across the borders. Both manual and digital form of document exchange is used around the world where the ratio of digital form is getting larger and replacing its counterpart.

One of the most prominently used trade document is a certificate of origin (CO) which is used to prove origin country of a traded good. Proof of origin is important as treatment for the good differs according to a trade agreement as well as status of a country where the good is from.

Depending on agreements between different countries as well as their level of preparations in CO management, cross-border CO exchange procedures and complexity can vary greatly. In order to understand the details, this paper will study background and history of Cos as well as policies on CO management. Then it will list different types of COs and their electronic forms, also known as electronic Certificate of Origin (eCO). Ultimately this paper will conclude by drawing implications from the listing, for both related policies and technicality that can be referenced by policy makers who are trying to implement cross-border eCO exchange in the future.

In addition, the paper will study the Korea-China cross-border eCO exchange or Electronic Origin Data Exchange System (EODES) case which provides real world case details. The case study would provide policy makers insight information of an actual system that is currently in operation as well as details of regulations on cross-border eCO exchange in the region.
