Importers check container status expecting a yes or a no. What they get is a small grid of independent flags, any one of which can stop a truck. A container can be physically sitting in the stack, discharged days ago, and still be undispatchable because one line in that grid says the wrong thing.

Understanding the grid saves a remarkable amount of money, because most demurrage is not caused by slow trucking. It is caused by someone assuming a container was ready three days before it actually was.

The flags that matter

Terminal systems differ in wording, but the same underlying checks apply at PortMiami and Port Everglades.

Vessel discharged

The box is off the ship. This is necessary but not close to sufficient. A freshly discharged container often is not yet available to pick up — it may still be in the working stack, or the terminal may not have completed its inventory update.

Terminal availability

The terminal is willing to hand it over. This is the flag most people mean when they say “available.” It can flip back to unavailable if the box gets buried, if the terminal restows, or during equipment outages.

Customs status / CBP hold

Released, or held. A hold can be a documentary review, an exam, or an agency referral to FDA, USDA or another agency. Our guides on customs exams for Miami importers and FDA and USDA agency holds cover what each type involves and roughly how long they run.

Line release / freight release

The ocean carrier has been paid and has released the cargo. This is the one that silently blocks more pickups than any other. Ocean freight, destination charges, or a telex release that never got issued will hold a box that is otherwise perfectly clear.

Hold for charges

Demurrage, exam fees or terminal charges owed. Even a released, cleared, available container will not gate out with an unpaid balance.

Booking or equipment flags

For exports, the equivalent checks are booking validity, earliest receiving date and gate cutoff. See our guide to export drayage and ERD at PortMiami.

Why “it says available” still gets a truck turned away

A driver arrives, gets to the gate, and the move fails. Common causes:

• The status was checked yesterday and something changed overnight.
• The line release posted, but a terminal charge was added after.
• The box is available but there is no appointment slot for the window the driver has.
• The container was restowed and is temporarily inaccessible.
• The chassis situation changed — the box is available but there is no usable chassis at that terminal at that hour.

A failed gate attempt is not free. Depending on the circumstances it can generate a dry run charge, which we break down alongside other drayage accessorial charges.

The practical checking rhythm

The day before pickup: confirm all flags are clear, confirm the appointment, confirm the chassis plan. This is the check that prevents dry runs.

The morning of pickup: re-check the release and hold flags specifically. These are the two that move overnight.

When a hold appears: find out which agency and which type immediately. An intensive exam has a very different timeline from a document review, and the difference determines whether you should be arranging a pre-pull or simply waiting.

Throughout: watch the last free day against the actual availability date, not the vessel date. Our explainer on last free day covers how it is calculated.

What good carriers do differently

A carrier that monitors status actively rather than reactively catches the release the hour it posts and gets into the appointment queue before the slots go. A carrier waiting for you to email “it’s ready” starts the process a day later — and on a tight last free day, a day is the whole margin.

Go Drayage tracks container status on its own platform and dispatches from a 5-acre Miami yard with company-owned equipment, which means when a hold clears at 2pm, there is a truck available to act on it rather than a search for one. You can see how the tracking side works on our shipment tracker page, or review the wider sequence in our vessel-to-delivery timeline.

When the status will not clear in time

Sometimes the release comes too late to deliver before free time expires, or your warehouse is closed. The move that protects you is pulling the container off the terminal and into yard storage, which stops the terminal clock even though the cargo is not yet at its destination. Terminal storage is almost always the most expensive place to leave a box.

If you are staring at a container that will not clear and a last free day that will, contact the team — the decision usually needs to be made the same day.

Frequently asked questions

My container says available but my carrier says they cannot pick it up. Why? Availability is only one of several flags. The most common blockers behind an “available” status are an outstanding line release, an unpaid terminal or demurrage balance, a customs or agency hold posted separately, or simply no appointment slot in the window your carrier can work. Ask which specific flag is blocking it.

How long does a customs hold usually take to clear? It depends entirely on the type. A documentary review can clear in a day; a physical or intensive exam involves moving the container to an exam site and can run considerably longer. Get the hold type identified early, because it determines whether you should be planning around a short wait or arranging storage.

Who is responsible for checking container status, me or my drayage carrier? In practice a good carrier monitors it continuously and tells you when something changes, but the release and payment flags usually depend on actions by you, your customs broker or your forwarder. Treat it as shared: the carrier watches the terminal side, you clear the commercial and customs side.
