About the Seattle to Singapore shipping route
Seattle to Singapore is a 7,171 nautical mile shipping route on a direct course, heading north west from the United States to Singapore. That is 13,281 km of water against 12,988 km as the crow flies. No canals or major straits on this leg, the ship stays close to the direct line.
At sea, the voyage lasts 24.9 days at 12 knots, 21.3 days at 14 knots and 16.6 days at 18 knots. Liner schedules on the lane quote 25 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).
548 nm of the route, 8% of it, lies inside North American 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 USSEA to SGSIN start at $6,815 for a 20GP and $9,450 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 Singapore (SGSIN) carriers give about 6 free days before demurrage and detention charges start, so plan the truck or rail pickup before the box lands.
