Busan to Colombo shipping route.

The shipping route from Busan, South Korea to Colombo, Sri Lanka covers 4,136 nautical miles port to port, via Strait of Malacca. On a globe the two ports sit 5,906 km apart, so the ship sails 1.30 times the straight line distance. On the way the vessel passes Strait of Malacca.

Pure steaming time is 12.3 days at 14 knots. A carrier that slow steams at 12 knots to save fuel needs 14.4 days, and a fast 18 knot string about 9.6. Container transit time on a liner service is longer than the steaming time: ships call at other ports on the rotation, and cargo may transship at a hub. Add terminal time at Busan and Colombo to plan the full ocean transit time.

The next option is via Sunda Strait, 4,761 nautical miles, 625 nm longer than the main route. Carriers pick it when Sunda Strait is congested or closed.

Container freight rates on Busan to Colombo move with fuel prices, ship capacity and the season. Compare several carriers before booking: the cheapest sailing is often the slowest one. At Colombo (LKCMB) carriers give about 5 free days before demurrage and detention charges start, so plan the truck or rail pickup before the box lands.

Of the 65 port to port routes from Busan in this directory, Colombo is the 19th shortest. Closer destinations include Tanjung Priok (2,876 nm), Port Klang (2,816 nm) and Laem Chabang (2,570 nm).
