The Northwest Seaport Alliance (NWSA), encompassing the ports of Seattle and Tacoma, has released its Weekly Volumes & Metrics Report for the week ending July 25, 2025, revealing significant dips in international imports and vessel lifts. These decreases are largely attributed to vessel delays and voids.

According to the report, international imports and vessel lifts saw substantial declines both week-over-week and when compared to the July 2024 weekly average.

Key figures for the week ending July 25 include:

• International Imports: Down 24.5% from the previous week and 25.9% compared with the July 2024 weekly average. A total of 10,386 containers were imported. This is also 19.2% lower than the 2025 year-to-date average and 23.6% lower than the 2024 weekly average.

• Vessel Lifts: Experienced an even steeper drop, down 38.5% from the week before and 37.8% compared to the July 2024 weekly average. The NWSA reported 19,136 vessel lifts for the week. This figure is also 29.4% lower than the 2025 year-to-date average.

Reasons for the Decreases: The primary cause for these significant reductions was operational disruptions. The report specifically notes:

• Two voids (scheduled vessel calls that did not occur).

• Two arrivals delayed into the following week.

• Two additional calls delayed from the previous week.

These ongoing delays have made it difficult to assess typical volume trends on a weekly basis throughout July, leading to "up and down" volumes.

In contrast to imports and vessel lifts, truck transactions did not see a significant decrease. Truck transactions were only down 5.5% from the week before and remained almost steady with the July 2024 weekly average, showing only a 1.1% decrease. A total of 24,225 truck transactions were recorded for the week ending July 25.

Looking ahead, the NWSA anticipates continued fluctuating trends for next week, with expectations for higher volumes. The report, authored by Kate Nolan, Manager of Communication & Outreach for The Northwest Seaport Alliance, also highlighted broader market concerns.

Feedback on recent tariff announcements issued on August 1 has centered around continued lack of clarity and a lack of market confidence regarding implementation and consistency of application. This uncertainty is leading some small supply chain businesses to consider closure or slow down operations to navigate the current environment
