Antwerp to Seattle shipping route.

The shipping route from Antwerp, Belgium to Seattle, United States covers 9,023 nautical miles port to port, via Panama Canal. On a globe the two ports sit 7,913 km apart, so the ship sails 2.11 times the straight line distance. On the way the vessel passes Panama Canal, so canal transit fees and waiting time at the canal are part of every voyage.

Pure steaming time is 26.9 days at 14 knots. A carrier that slow steams at 12 knots to save fuel needs 31.3 days, and a fast 18 knot string about 20.9. 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 Antwerp and Seattle to plan the full ocean transit time.

The next option is via Strait of Magellan, 14,485 nautical miles, 5,462 nm longer than the main route. Carriers pick it when Strait of Magellan is congested or closed.

1,758 nm of the route, 19% of it, lies inside North American ECA, US Caribbean Sea ECA and North 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 Antwerp to Seattle move with fuel prices, ship capacity and the season. Compare several carriers before booking: the cheapest sailing is often the slowest one. At Seattle (USSEA) carriers give about 3.94 free days before demurrage and detention charges start, so plan the truck or rail pickup before the box lands.

Of the 61 port to port routes from Antwerp in this directory, Seattle is the 42nd shortest. Closer destinations include Ho Chi Minh City (8,991 nm), Tanjung Priok (8,639 nm) and Singapore (8,362 nm).
