The tariff-driven cargo rush gave Seattle’s port a temporary boost—but now forward-bookings are vanishing, and the slowdown is setting in.
Volume is up for now, but early warning signs of a tariff-fueled slowdown are flashing bright red 🚨
Seattle port traffic is up—just not for long
Despite viral claims that the Port of Seattle is a “ghost town”, the reality is more nuanced. March volumes jumped 18.4%, with a short-term boost from importers front-loading cargo ahead of Trump’s new 145% tariffs on Chinese goods.
So yes—more ships were coming in.
Yes—cargo was moving.
But that boom? It’s already over.
The catch: forward-buying masked the pain
Port of Seattle and Tacoma volumes soared early this year because shippers raced to beat the tariff clock. Between January and March, container throughput rose 24% YoY, according to Northwest Seaport Alliance data.
But that wasn’t demand—it was desperation.
Now that the tariffs are in place, bookings have nosedived:
- 📉 Ocean bookings into Seattle/Tacoma fell 29% between March 30 and April 21
- 🛑 30% of ships are arriving with lighter loads
- ❌ Exporters are canceling shipments mid-transit
And vessel arrivals in April dropped 12% YoY, with some sources putting the number closer to 27%.
Operator POV: tariffs are silently nuking supply chains
The optics are misleading. Just because some ships are docked doesn’t mean all is well.
In fact, the pipeline is drying up.
Take SwaddleDesigns, a babywear brand based in Seattle. They halted a container this month because Trump’s tariffs would’ve slapped a $300,000 tax on a $200,000 order.
That’s not inflation. That’s strangulation.
And it’s not just imports. The Pacific Northwest exports hay, apples, and fries. Thanks to China’s retaliatory tariffs, some exporters are retrieving their goods from the dock—sales canceled, contracts voided.
Says one port insider: “They’re just picking them up and trying to find another home for them.”
This isn’t a one-week blip. This is the start of a tariff shockwave that will hit fully by mid-May, when the empty bookings of April materialize as empty docks.
Meanwhile, Seattle’s cruise season sails on
To confuse things further, Seattle’s port is booming in another way: cruises.
The city expects a record 298 cruise calls this year, bringing in $900M in economic impact and 5,000+ jobs, per KIRO Newsradio.
But don’t get it twisted—cruise traffic ≠ cargo recovery.
Cruise ships don’t replace the massive volumes of container freight, and while they’re good for local hospitality, they don’t help manufacturers, retailers, or trucking fleets survive tariff-induced whiplash.
Why it matters: the worst is still en route
Commissioner Ryan Calkins didn’t sugarcoat it. The latest forecasts show monthly cargo traffic could drop 25% or more in the next quarter.
And because of global shipping lag times, we won’t feel the full sting until weeks after the April slowdowns. Call it the tariff time bomb.
Even if the Trump administration eases tariffs tomorrow (and there are rumors it might), restarting the supply chain isn’t instant. As one longtime port-watcher put it:
“This pipeline has been shut off and it’s not like you can turn it back on and it starts up again in a day.”
Expect pain. Expect disruption. And if you’re a DTC brand or importer?
Expect a summer of chaos.
The takeaway
📈 March numbers look good because everyone panicked and ordered early.
📉 April bookings cratered. May arrivals will follow.
🔥 The Port of Seattle isn’t a ghost town—yet. But the tariffs are turning it into one.
