For most of the last decade, the mental model was simple: the West Coast clogs, the East Coast catches the overflow. Shippers diversified eastward on that premise. The data from the first half of 2026 says that premise has quietly expired.

Across 12 major U.S. container ports, the two coasts now post roughly comparable total import cycle times, measured from vessel arrival through berth, discharge, and the container leaving the terminal gate. But they get there through completely different bottlenecks, and the difference matters more than the average.

The West Coast problem is the berth

At Los Angeles and Long Beach, the time it takes to discharge a vessel once it is berthed runs 28 to 58 hours. That is two to four times longer than any East or Gulf Coast port. It is not a backlog and it is not a labor event. It is the physics of working the largest vessels afloat at the San Pedro Bay complex, and it has not materially improved across 18 months of data.

The vessels are not waiting at anchor. Arrive-to-berth times in San Pedro Bay are low and stable. The slowdown is at the crane, not the queue. That is the part shippers tend to misread, because "West Coast congestion" still conjures images of vessels stacked off the coast. The constraint moved inside the fence line, and it is structural. No operational quick fix resolves it without changing terminal productivity or the size of the vessels calling.

The East Coast problem is the dwell

The East and Gulf Coast bottleneck sits at the other end of the cycle: how long a container sits in the yard after it is discharged before it exits the gate.

Norfolk is the clearest case. Its discharge-to-gate-out time has not dropped below 73 hours in a single month since January 2025, when it sat at 122. It is improving, slowly, but it remains the most persistently congested terminal in the country on dwell, running two to three times the East Coast average. A shipper routing imports through Norfolk should plan for extended terminal pickup windows as a baseline, not an exception.

The important distinction: dwell congestion is variable and responsive to operational intervention in a way berth congestion is not. Charleston worked its way down. Miami posted the best export dwell improvement on the coast. Savannah absorbed real volume growth, vessel calls up from 61 a month to over 100, while holding the lowest dwell times on the East Coast. East Coast congestion is a problem you can manage your way out of. West Coast berth congestion is one you plan around.

"Equal" hides a wide spread

The coast-level averages converge, but do not read that as twelve interchangeable ports. The spread between the slowest and fastest terminals is the widest it has been in the dataset.

Norfolk and Seattle sit at the top of the total import cycle, both well above 110 hours. Los Angeles and Long Beach land closer to 80 to 90, despite their berth penalty, because their terminal dwell is lower. Tacoma, Charleston, and Miami run the fastest overall. The coast you pick matters far less than the specific terminal you pick. Routing decisions made on the old "East Coast is faster" heuristic will be wrong as often as they are right in 2026.

Two terminals are worth watching specifically. Jacksonville's dwell has climbed from 38 hours in April 2025 to the 82 to 106 range in mid-2026, a near-tripling. It is a small port, so a single service change could explain it, but the trend has been consistent for more than a year. Seattle has posted dwell above 100 hours in five separate months with no improvement trend, also at low call volume. Neither is a crisis. Both are the kind of early operational drift that shows up in the data long before it shows up in a rate quote.

The signal worth flagging

One pattern in the 2026 data does not have a clean explanation from port operations alone. In February 2026, New York and Norfolk hit their worst export dwell readings since early 2025 in the same month, then both partially recovered. Two major ports moving together like that points to something at the service or capacity level rather than anything happening inside either terminal. The port-level data cannot confirm the cause. It can only tell you the two ports moved in lockstep, which is itself the kind of thing worth knowing before it becomes a headline.

What this means if you move freight

Stop treating the coast as the unit of decision. The useful unit is the terminal and the specific stage of the cycle that constrains it. If your cargo is time-sensitive on the import pickup side, a low-dwell terminal like Savannah, Charleston, or Miami beats a marquee West Coast gateway. If you are optimizing for vessel transit and berth availability, the calculus flips.

The broader point: congestion in 2026 is not a single number going up or down. It is a set of distinct, stage-specific constraints that move independently, sometimes in opposite directions on the same coast in the same month. The shippers who see it that way, at the granularity of berth versus dwell versus export staging, are the ones routing around problems their competitors are still averaging into invisibility.

See this for your own boxes

Everything above came from container-level tracking across these 12 ports. The same view works for your lanes, your terminals, and your containers, broken into the same stages: how long your boxes wait for berth, how long discharge takes, and how long they sit before they clear the gate.

That is what BoxTrack does. It turns the port performance you just read about into a live, operational picture of where your freight actually is and where it is about to slow down, early enough to reroute around it.
