Colombo to Houston shipping route.

Ships leaving Colombo for Houston head north and cover a sea distance of 10,218 nautical miles (18,924 km), via Suez Canal. The straight line between the ports is 15,904 km; coastlines and shipping lanes add the rest. On the way the vessel passes Suez Canal, Bab-el-Mandeb and Strait of Gibraltar, 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 Colombo and Houston 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 12,032 nm instead of 10,218 nm and spends roughly 5.4 extra days at sea. Ask your forwarder which routing the carrier uses: the booking price and the arrival date both depend on it.

2,746 nm of the route, 27% of it, lies inside North American ECA and 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 Colombo to Houston move with fuel prices, ship capacity and the season. Compare several carriers before booking: the cheapest sailing is often the slowest one. At Houston (USHOU) 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 65 port to port routes from Colombo in this directory, Houston is the 63rd shortest. Closer destinations include Balboa (9,819 nm), Cartagena (9,578 nm) and Los Angeles (9,376 nm).
