Importers face uncertainty as a court case about tariffs imposed by President Donald Trump affects the upcoming holiday shipping season, according to the Port of Los Angeles.

A US Court of International Trade ruling threatened to delay or block Trump’s “Liberation Day” tariffs, but a federal appeals court temporarily reinstated them.

Deadlines for responses are set for June 5 and June 9, with no clear resolution yet.

Shipping volumes at the Port of Los Angeles are significantly lower than last year. May cargo volume is expected to decline by double digits, following a 30% drop in early and late May.

Ten vessel arrivals in June have been canceled, including five in the first week.

Companies are reluctant to place orders due to fluctuating tariff rates, with nearly 60 trade policy announcements since January.

🧠 Food for thought

1️⃣ Historical pattern of import surges followed by sharp declines

The current shipping decline at the Port of Los Angeles follows a pattern seen in previous trade disputes, where tariff announcements trigger inventory stockpiling followed by dramatic volume drops.

During the 2019 trade tensions, eastbound shipping from China to the U.S. increased by 7.8% as companies rushed to import goods before tariffs were imposed 1.

This cycle is now repeating, with the Port of Los Angeles expecting May volume to drop by double-digit percentages and reporting 10 canceled vessel arrivals for June, including five in the first week alone.

The last major tariff implementation in 2019 threatened nearly 1.5 million U.S. jobs and over $186 billion in economic activity according to a study commissioned by the Port of Los Angeles 2.

This pattern creates operational challenges for ports, as they must first manage congestion during the rush period and then deal with underutilization when volumes collapse.

2️⃣ Tariff uncertainty ripples beyond ports to regional economies

Port volume declines directly impact regional employment, with California ports already reporting that longshore workers are facing reduced hours similar to pandemic conditions.
