Maritime Cargo Comings and Goings 2024

The Northwest Seaport Alliance (NWSA or the alliance) is one of the top container ports in North America. Cargo operations through the Seattle and Tacoma gateway have a significant impact on international trade and the local economy, providing jobs and revenue to Washington state — one of the most trade-dependent states in the country.

The NWSA produces an annual cargo trade report that highlights trade activity, including country, port, and commodity breakdowns, as well as profiles on the top 10 trading partners by total 20-foot equivalent units (TEUs).

Here is a summary of NWSA 2024 volumes:

TEUs

NWSA handled 3.3 million TEUs in 2024, up 12.3% from 2023’s 3 million TEUs. Strong imports were driven by shippers moving cargo ahead of possible tariffs. In addition, shippers diverted cargo to the West Coast due to uncertainty around the International Longshoremen’s Association (ILA) and United States Maritime Alliance (USMX) contract negotiations. Uncertainty around contract negotiations concerning Canadian railroads also contributed to diverted cargo.

Global reach

NWSA has regular weekly services with key markets in Asia, Europe, Central and South America, and Oceania, and the products from our region reach markets all over the world. Asia and Pacific make up most of the volume through the NWSA gateway, accounting for 92.2% of trade by TEUs in 2024.

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.

Here are the types of commodities moved through NWSA container terminals in 2024 by TEUs and vessel value.

Export gateway of choice

hay and forage:

• apples
• frozen potato products (French fries)
• fresh potatoes
• legumes (peas, beans, and lentils)
• grass feed
• hops and hop extract

In addition, the NWSA is the nation’s second-largest gateway for containerized refrigerated (reefer) exports. Top reefer exports include:

• frozen potato products (French fries)
• apples
• fish
• fresh potatoes
• pork
• dairy products
• vegetables
• beef

Gateway to Alaska and Hawaii

While most cargo is international, the NWSA is also the gateway to Alaska and Hawaii. In 2024, 21.9% of cargo was domestic. NWSA domestic terminals handle more than 80% of containerized ocean shipments between Alaska and the lower 48 states.

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 2024, the alliance handled 402,681 metric tons of breakbulk. Breakbulk metric tons were down 11.2%. High interest rates had an impact on agricultural, mining, and construction equipment sales. 

After a record-breaking 2023, auto units were down 0.3% in 2024.

Vessel calls

You have probably heard the phrase “big-ship ready” a lot. It’s more than just a buzzword. The NWSA has been proactively planning and developing terminal improvements to remain competitive in the changing global shipping industry. That includes working with tenants to make major capital improvements to marine terminal facilities to meet the demand of larger vessels. In early March 2025, Terminal 5 in Seattle (North) Harbor welcomed the 16,000 TEU MSC Ilenia, the largest container vessel to call at the terminal to date.

Phase 2 of Terminal 5 was completed in Q1 2024. Read about the project→

Fun fact: The largest vessel handled in the gateway is the 17,859 TEU CMA CGM Benjamin Franklin, which called at Terminal 18 in the Seattle (North) Harbor in 2016.
