「關貿網路」股份有限公司前身為於1990年奉中華民國行政院核定成立的「貨物通關自動化規劃推行小組」。該小組之任務為建置台灣進出口通關自動化系統，協助貿易商透過網路連線即可完成進出口通關及關稅繳納作業，以降低貿易成本、加速通關作業。經過4年的努力，先後達成海運與空運的貨物通關自動化，使原本需4小時之空運通關作業平均時間縮短為0.216小時，亦使原本需6小時之海運通關作業平均時間降低為2.049小時，且免審免驗貨物之平均通關已低於10分鐘，為台灣貿易史上開啟了嶄新的時代。任務圓滿達成後，政府考量到當時台灣產業在電子化進程上仍有進步空間，因此擬轉型後持續營運，裁定由政府與民間合組民營公司型態於1996完成民營化，並定名為「關貿網路」股份有限公司(英文名稱Trade-Van，Van為Value Added Network的縮寫)，繼續加強通關自動化服務，並積極開拓網路資源，研發尖端技術，擴展營業範圍，提供全方位加值網路服務。關貿網路股份有限公司於2011年掛牌上市，目前已有超過5萬9仟多家客戶，業務範圍包含通關網路服務、電子商務服務、全球運籌服務、政府專案服務、金融保險服務、財產管理服務、電子報稅服務、資訊安全服務及創新金融服務。除此之外本公司自有營運機房及客服中心，為客戶提供24x7不間斷之服務。The predecessor of Trade-Van was "The Cargo Clearance Automation Planning and Promotion (CCAPP) Task Force", which was formed under the approval of the Executive Yuan of the Republic of China to address the difficulties faced by the exporters and importers in customs clearance. The mission of the CCAPP task force was thus to build a clearance automation and customs duty payment system to speed up customs clearance operations and help traders reduce trading costs. After four years of efforts, the CCAPP task force successfully set up the customs clearance automation system, which reduced the air cargo clearance time from 4 hours to 0.216 hours on the average and shortened the sea cargo clearance operations from 6 hours to an average of 2.049 hours. After successful completion of the mission, the CCAPP task force was privatized and reformed as a company (with the government holding less than 50% of shares) in 1996. The company was named Trade-Van Information Services Co. (VAN stands for "Value Added Network"), whose mission was to continue strengthening customs clearance automation services, actively explore the network resources, research and develop state-of-the-art technology, expand business and service scopes, and provide a full range of value-added network services.
