Seaports handle around 80 percent of international cargo. In 2005 a total of 105,251 metric tons of cargo were transported by water. Colombia's most important ocean terminals are Barranquilla, Cartagena, and Santa Marta on the Caribbean Coast and Buenaventura and Tumaco on the Pacific Coast. Exports mostly pass through the Caribbean ports of Cartagena and Santa Marta, while 65 percent of imports arrive at the port of Buenaventura. Other important ports and harbors are Bahía de Portete, Leticia, Puerto Bolívar, San Andrés, Santa Marta, and Turbo. Since privatization was implemented in 1993, the efficiency of port handling has increased greatly. Privatization, however, has had negative impacts as well. In Buenaventura, for example, privatization of the harbor has increased unemployment and social issues. There are plans to construct a deep-water port at Bahía Solano.
