The Port of Kaohsiung was designed to handle 10 million TEUs (twenty-foot equivalent units) per year, but has been overloaded since 2007, and currently has a throughput of 10.26 million TEUs. The excess containers pack every terminal and even nearby consolidation sheds. Containers for which there is no room have been diverted to other ports, though there are no precise figures for the number rerouted.
高雄港原設計有 1,000 萬 TEU 的貨櫃量，但自 2007 年起即超載，目前已達 1026 萬 TEU；超額的貨櫃量塞爆了所有的貨櫃碼頭，就連港區附近的貨櫃集散場也早已全部爆滿，擠不進來的貨櫃只好忍痛轉往其他港口，確切數量難以估計。
