About the Seattle to Incheon shipping route
Seattle to Incheon is a 5,110 nautical mile shipping route on a direct course, heading north west from the United States to South Korea. That is 9,464 km of water against 8,350 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 17.7 days at 12 knots, 15.2 days at 14 knots and 11.8 days at 18 knots. 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 Seattle and Incheon to plan the full ocean transit time.
548 nm of the route, 11% 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.
Container freight rates on Seattle to Incheon move with fuel prices, ship capacity and the season. Compare several carriers before booking: the cheapest sailing is often the slowest one. At Incheon (KRINC) carriers give about 10 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, Incheon is the 10th shortest. Closer destinations include Callao (4,868 nm), Busan (4,675 nm) and Cartagena (4,515 nm).
