Incheon to Charleston shipping route.

Ships leaving Incheon for Charleston head north east and cover a sea distance of 10,228 nautical miles (18,942 km), via Panama Canal. The straight line between the ports is 11,732 km; coastlines and shipping lanes add the rest. 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 30.4 days at sea. Slow steaming at 12 knots stretches it to 35.5 days, while 18 knots brings it down to 23.7. 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 Incheon and Charleston to plan the full ocean transit time.

The next option is via Suez Canal, 13,228 nautical miles, 3,000 nm longer than the main route. Carriers pick it when Strait of Gibraltar 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 Incheon to Charleston move with fuel prices, ship capacity and the season. Compare several carriers before booking: the cheapest sailing is often the slowest one. At Charleston (USCHS) carriers give about 4 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 Incheon in this directory, Charleston is the 49th shortest. Closer destinations include Houston (10,173 nm), Algeciras (9,597 nm) and Valencia (9,340 nm).
