Seattle to Lagos (Apapa) shipping route.

The shipping route from Seattle, United States to Lagos (Apapa), Nigeria covers 9,460 nautical miles port to port, via Panama Canal. On a globe the two ports sit 12,004 km apart, so the ship sails 1.46 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.

Shipping time depends on speed. At 14 knots, a common container ship service speed, the passage takes 28.2 days at sea. Slow steaming at 12 knots stretches it to 32.8 days, while 18 knots brings it down to 21.9. 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 Seattle and Lagos (Apapa) to plan the full ocean transit time.

The next option is via Strait of Magellan, 12,405 nautical miles, 2,945 nm longer than the main route. Carriers pick it when Strait of Magellan is congested or closed.

1,267 nm of the route, 13% 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 Lagos (Apapa) move with fuel prices, ship capacity and the season. Compare several carriers before booking: the cheapest sailing is often the slowest one. At Lagos (Apapa) (NGAPP) carriers give about 7 free days before demurrage and detention charges start, so plan the truck or rail pickup before the box lands.
