The container is at the terminal. The vessel is calling at the port. The booking is confirmed. It sounds like the cargo is guaranteed to depart.
Yet in ocean freight, a container can already be inside the terminal and still be left behind.
The industry even has a term for this: rolled cargo - a shipment misses its planned sailing and is moved to a later vessel.
There are several possible reasons:
📦 Insufficient capacity. More cargo may be booked than the vessel can ultimately accommodate.
⚖️ Missing VGM. Under SOLAS requirements, a packed container needs a Verified Gross Mass before loading. Without it, the container cannot be loaded.
📄 Documentation or customs issues. Incomplete paperwork, customs complications or missed deadlines can prevent loading.
⏰ A missed cut-off. The vessel's departure time is not the only deadline. Cargo gate-in, documentation and VGM can each have their own cut-off.
And a rollover does not necessarily mean a delay of only a few days. Cargo is generally moved to the next available vessel, but even that sailing is not always guaranteed.
This is why ocean freight requires attention far beyond simply booking space. A shipment needs to be monitored until the container is actually loaded on board.
At LOADSTAR, we organise sea and multimodal freight and coordinate the key stages required to keep cargo moving according to plan.
