Seattle to Haiphong shipping route.

The shipping route from Seattle, United States to Haiphong, Vietnam covers 6,353 nautical miles port to port, on a direct course. On a globe the two ports sit 10,961 km apart, so the ship sails 1.07 times the straight line distance. No canals or major straits on this leg, the ship stays close to the direct line.

Shipping time depends on speed. At 14 knots, a common container ship service speed, the passage takes 18.9 days at sea. Slow steaming at 12 knots stretches it to 22.1 days, while 18 knots brings it down to 14.7. Liner schedules on the lane quote 28 to 42 days port to port, because the services call at other ports and some transship. Over the last 30 days we counted 17 sailings by 2 carriers (CMA CGM and MSC).

548 nm of the route, 9% 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 VNHPH start at $6,026 for a 20GP and $8,546 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 Haiphong (VNHPH) 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 Seattle in this directory, Haiphong is the 25th shortest. Closer destinations include Auckland (6,338 nm), New York (6,212 nm) and Manila (6,078 nm).
