NWSA 2025 volumes at a glance
TEUs
NWSA handled 3.2 million 20-foot equivalent units (TEUs) in 2025, down 5.5% from 2024’s 3.3 million TEUs. Strong import shipments in anticipation of tariffs and uncertainty related to Canadian longshore and rail labor contract negotiations contributed to strong volumes in 2024.
Global reach
NWSA has regular weekly services with key markets in Asia, Europe, Latin America, and Oceania, and the products from our region reach markets all over the world. Asia made up most of the volume through the NWSA gateway, accounting for 90.5% of trade by TEUs in 2025.
Strong trade relationships
Washington state is one of the most trade-dependent states in the nation and has established strong trade relationships with many other countries. These top countries import and export valuable merchandise and commodities through the NWSA gateway.

Washington agriculture
As has been noted in past posts, agricultural products are a huge part of the NWSA’s export volumes. The Port of Seattle recognizes that our state would never be an agricultural leader without the contributions of migrant farm workers and partners.

Breakbulk and autos
The NWSA provides a range of services like shipping breakbulk, project cargo, heavy lift cargo, and autos — including helicopters — with regularly scheduled services to and from Asia, Europe, and Oceania, and by transshipment to anywhere in the world.
In 2025, auto units finished down 18.8%, as high interest rates and inflation muted car sales. Breakbulk metric tons were down 18.7%. High interest rates took a toll on agricultural, mining, and construction equipment sales.
If you are a watcher of Seattle’s working waterfront, you may have noticed auto vessels calling at Terminal 46. View recent operations.
