The Northwest Seaport Alliance (Seattle + Tacoma) Weekly Volumes & Metrics Report 8/4/25

For the week ending in July 25, international imports and vessel lifts saw significant dips week over week and compared to the July 2024 weekly average. This was largely due to two voids and two arrivals delayed into the following week, though this week also had two additional calls that had been delayed from the previous week. Truck transactions did not see a significant decrease. 

International imports were down 24.5% from the week before and 25.9% compared with the July 2024 weekly average. Truck transactions were only down 5.5% from the week before and almost held steady with the July 2024 weekly average with a 1.1% decrease. Vessel lifts were down 38.5% from the week before and 37.8% compared to the July 2024 weekly average.  

Delays have so far led to up and down July volumes. It is typically difficult to assess volume trends on a weekly basis, but July has so far been especially difficult given the high number of delays and some voids. Next week will likely continue this fluctuating trend and is expected to be higher.

Market Intel

Feedback from the latest round of tariff announcements issued on August 1 has been centered around continued lack of clarity. There is lack of confidence in the market on implementation and consistency of application for tariffs.  

We are seeing small supply chain businesses considering closure, and others slow rolling their operations or cargo to ensure that they can stay open through the uncertainty.
