Houston to Durban shipping route.

The shipping route from Houston, United States to Durban, South Africa covers 8,324 nautical miles port to port, via Cape of Good Hope. On a globe the two ports sit 14,884 km apart, so the ship sails 1.04 times the straight line distance. On the way the vessel passes Cape of Good Hope.

Shipping time depends on speed. At 14 knots, a common container ship service speed, the passage takes 24.8 days at sea. Slow steaming at 12 knots stretches it to 28.9 days, while 18 knots brings it down to 19.3. 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 Houston and Durban to plan the full ocean transit time.

835 nm of the route, 10% of it, lies inside North American ECA and US Caribbean 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 Houston to Durban move with fuel prices, ship capacity and the season. Compare several carriers before booking: the cheapest sailing is often the slowest one. At Durban (ZADUR) carriers give about 3 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 Houston in this directory, Durban is the 36th shortest. Closer destinations include Djibouti (8,069 nm), Cape Town (7,610 nm) and Jeddah (7,409 nm).
