Su-ao Port is situated at and dominates the Su-ao Bay in Lanyang Plain, northeast of Taiwan. A fine natural port in terms of terrain conditions, it is 50 NM away from Keelung Port in the north and 40 NM from Hualien Port in the south, and can be reached by Taiwan's North Link railway directly from Taipei and Hualien. There are also Tai No. 9 Highway and the Coastal Highway to connect to Taipei and Keelung, reaching out in all directions. Access to the Port zone consists of Special No. 1 Highway of Su-ao Township and Lanyang No. 2 Tunnel, facilitating the transportation of goods, which provides shipping companies and goods owner with fast and convenient service. Su-ao Port thus makes a best auxiliary port to Keelung Port, as well as leads the movement to prosperity in Lanyang area.

The water of Su-ao Port covers an area of 2.9 million sq. m., and its area on land stretches for 860 thousand sq. m. Thirteen wharves, in total length of 2,610 m, are disposed in the Port, including one for the working vessels, and twelve commercial wharves (which include six for sundries goods, one for coal, one for petroleum, two for cement and two for chemicals). These wharves have water depth ranges from –7.5 to –15 m, and have lengths varying from 125 to 300 m, where vessel of Panamax class can stop. At the Port, imports are mainly of coal, fuel, Paraxylene, slag, steel billets, etc., while exports are chiefly cement, pure Paraxylene acid and Potassium Sulfate. Operation-wise, delivery on board prevails. With various services expanding each day, the Port has developed toward an international commercial port.

In addition to the four tugs, one line boat, one patrol boat and one cleaner ship, which already make up good working facility to the Port, a port management information system is set up. In wharf and transit shed operations, we have opened, since January 1999, the loading/unloading operation of general sundries and bulk cargo to three private operators. When the Taipei-Yilan Freeway is complete, the hinterland of Su-ao Port will expand to encompass the Taipei metropolis, thus draw more industries to Lanyang area. Along with the firms coming to Yilan Science Park and Lize and Long-der industrial zones to set up plants, the function of Port will further be exerted to create a remarkable future for Su-ao Port.
