Cartagena to Karachi shipping route.

The shipping route from Cartagena, Colombia to Karachi, Pakistan covers 8,948 nautical miles port to port, via Suez Canal. On a globe the two ports sit 14,362 km apart, so the ship sails 1.15 times the straight line distance. On the way the vessel passes Strait of Gibraltar, Bab-el-Mandeb and Suez 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 26.6 days at sea. Slow steaming at 12 knots stretches it to 31.1 days, while 18 knots brings it down to 20.7. 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 Cartagena and Karachi to plan the full ocean transit time.

Red Sea security changes the sea distance on this lane. A ship sent via Cape of Good Hope sails 10,983 nm instead of 8,948 nm and spends roughly 6.1 extra days at sea. Ask your forwarder which routing the carrier uses: the booking price and the arrival date both depend on it.

1,935 nm of the route, 22% of it, lies inside Mediterranean Sea 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 Cartagena to Karachi move with fuel prices, ship capacity and the season. Compare several carriers before booking: the cheapest sailing is often the slowest one. At Karachi (PKKHI) 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 Cartagena in this directory, Karachi is the 46th shortest. Closer destinations include Incheon (8,948 nm), Mombasa (8,783 nm) and Busan (8,513 nm).
