Singapore to Houston shipping route.

Ships leaving Singapore for Houston head north east and cover a sea distance of 11,766 nautical miles (21,790 km), via Suez Canal. The straight line between the ports is 16,016 km; coastlines and shipping lanes add the rest. On the way the vessel passes Suez Canal, Bab-el-Mandeb, Strait of Malacca and Strait of Gibraltar, so canal transit fees and waiting time at the canal are part of every voyage.

Pure steaming time is 35.0 days at 14 knots. A carrier that slow steams at 12 knots to save fuel needs 40.9 days, and a fast 18 knot string about 27.2. Liner schedules on the lane quote 42 days port to port, because the services call at other ports and some transship. Over the last 30 days we counted 1 sailings by 1 carrier (CMA CGM).

The shortest route goes through the Red Sea. Since attacks on shipping began there in late 2023, many carriers send ships via Panama Canal instead. That route is 12,222 nautical miles, 456 more, and adds about 1.3 days at 14 knots. Longer voyages burn more fuel and tie up more ships, which is why freight rates on Red Sea lanes jumped when the diversions started.

2,746 nm of the route, 23% 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.

Recent freight rates for SGSIN to USHOU start at $11,700 for a 20GP and $13,000 for a 40GP. These are spot market prices from carriers that sail the lane; your quote will also include terminal handling, documentation and any bunker surcharge. 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 64 port to port routes from Singapore in this directory, Houston is the 64th shortest. Closer destinations include Cartagena (10,997 nm), Callao (10,858 nm) and Savannah (10,683 nm).
