Incheon to Shanghai shipping route.

Ships leaving Incheon for Shanghai head south west and cover a sea distance of 538 nautical miles (997 km), on a direct course. The straight line between the ports is 823 km; coastlines and shipping lanes add the rest. No canals or major straits on this leg, the ship stays close to the direct line.

Shipping time depends on speed. At 14 knots, a common container ship service speed, the passage takes 1.6 days at sea. Slow steaming at 12 knots stretches it to 1.9 days, while 18 knots brings it down to 1.2. 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 Shanghai to plan the full ocean transit time.

Container freight rates on Incheon to Shanghai move with fuel prices, ship capacity and the season. Compare several carriers before booking: the cheapest sailing is often the slowest one. At Shanghai (CNSHA) carriers give about 6 free days before demurrage and detention charges start, so plan the truck or rail pickup before the box lands.
