Summary of Port of Seattle Cargo Activity Amid Tariff Changes
As of late April 2025, the Port of Seattle has not been entirely empty as claimed by various social media posts. Despite assertions that international vessels ceased calling the port due to newly imposed U.S. tariffs, the Northwest Seaport Alliance (NWSA) reported that the port operated at normal capacity and even registered an increase in shipping activity compared to the same period in 2024.
While ship traffic generally remained consistent, the volumes of cargo arriving at the port were indeed unpredictable. The NWSA indicated that some vessels came in carrying as much as 30% less cargo than expected. This fluctuation can be attributed to the uncertainties created by U.S. tariff policies, particularly the significantly high duty rates on imports from China, which had risen to an unprecedented 145%.
Social media posts erroneously suggested that the port was effectively shut down and that no new international ships would be arriving post-April 29. Speculative images, such as one claiming to show the empty port on April 23, gained traction online, which were believed to exaggerate the situation. However, NWSA communications manager Kate Nolan clarified that while some effects of the tariffs were already noticeable—like canceled orders from exporters—claims of empty terminals or halted ship traffic were false.
On April 29, the port was actively preparing for the arrival of multiple international vessels, with 15 ships scheduled through early May, including 12 that either originated from or went through Chinese ports. Following this period, an additional 16 ships were slated for arrival, disproving claims of an abrupt cessation of shipping activity.
Furthermore, despite the backdrop of tariffs affecting shipment volumes and operational activities at the port, it was noted that there was a 7.3% increase in shipments to Seattle in the 30 days leading up to April 29. This surge was attributed, in part, to shippers accelerating cargo movements prior to the expected impact of tariffs.
In summary, while the NWSA recognized the real and immediate consequences of the tariffs—impacting jobs directly linked to cargo volume—the claim that Seattle’s marine cargo terminals were empty or that international vessels had stopped calling entirely was inaccurate. The port continued to function with a consistent level of international shipping activity, revealing that social media narratives often do not capture the full scope of operational realities. The situation was evolving, with the NWSA preparing for ongoing effects as they adapt to new trade policy challenges.
