With the widespread use of the internet, e-commerce transaction volume in world trade is increasing day by day. The desire of individuals or companies to supply a product they demand at certain standards and at a lower cost positively affects the demand for e-commerce. Many users prefer to order via e-commerce as it is both a simple and useful system. With the increasing volume of e-commerce transactions globally, more information is needed regarding the customs procedures applied to shipments. They are also subject to trade policy measures of that country in each shipment. These customs procedures are carried out on behalf of individuals or companies within the scope of indirect representation authority, by companies authorized for post and express cargo transportation. One of the ways to make the customs procedures of export and import shipments made within the scope of post and express cargo transportation in a simpler and shorter time is the Electronic Trade Customs Declaration (ETCD). Products with a certain value and amount of customs value and shipments such as samples and documents without commercial value are subject to ETCD. ETCD is also trying to alleviate the workload of customs administrations. In this study, by giving information about the ETGB process and its operation, strengths, weaknesses, opportunities and threats of this process have been tried to be determined by SWOT analysis. At the same time, suggestions were made for further improvement of the process. It is thought that the study will contribute to the literature due to the limited number of studies on this subject in the literature.
