Cartagena to Haiphong shipping route.

Ships leaving Cartagena for Haiphong head north and cover a sea distance of 10,191 nautical miles (18,874 km), via Panama Canal. The straight line between the ports is 16,525 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.

Pure steaming time is 30.3 days at 14 knots. A carrier that slow steams at 12 knots to save fuel needs 35.4 days, and a fast 18 knot string about 23.6. 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 Cartagena and Haiphong to plan the full ocean transit time.

The next option is via Suez Canal, 12,438 nautical miles, 2,247 nm longer than the main route. Carriers pick it when Strait of Gibraltar is congested or closed.

Container freight rates on Cartagena to Haiphong move with fuel prices, ship capacity and the season. Compare several carriers before booking: the cheapest sailing is often the slowest one. At Haiphong (VNHPH) carriers give about 4 free days before demurrage and detention charges start, so plan the truck or rail pickup before the box lands.
