Charleston to Busan shipping route.

Charleston to Busan is a 9,793 nautical mile shipping route via Panama Canal, heading north west from the United States to South Korea. That is 18,136 km of water against 11,886 km as the crow flies. On the way the vessel passes Panama Canal, so canal transit fees and waiting time at the canal are part of every voyage.

Shipping time depends on speed. At 14 knots, a common container ship service speed, the passage takes 29.1 days at sea. Slow steaming at 12 knots stretches it to 34.0 days, while 18 knots brings it down to 22.7. 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 Charleston and Busan to plan the full ocean transit time.

The next option is via Suez Canal, 13,159 nautical miles, 3,366 nm longer than the main route. Carriers pick it when Suez Canal is congested or closed.

367 nm of the route, 4% of it, lies inside North American ECA. In an emission control area ships must burn fuel with no more than 0.1% sulphur or clean the exhaust with scrubbers. That fuel costs more, and carriers add it to the ocean freight bill as a low sulphur or ECA surcharge.

Container freight rates on Charleston to Busan move with fuel prices, ship capacity and the season. Compare several carriers before booking: the cheapest sailing is often the slowest one. At Busan (KRPUS) carriers give about 10 free days before demurrage and detention charges start, so plan the truck or rail pickup before the box lands.

Of the 64 port to port routes from Charleston in this directory, Busan is the 48th shortest. Closer destinations include Melbourne (9,750 nm), Sydney (9,442 nm) and Tokyo (9,429 nm).
