What is Closing Time?
“Closing Time”—also referred to as CY Closing or Customs Release Deadline—is the final cutoff for the shipping line to receive customs release information. Goods must clear customs, obtain release authorization, and have that release information transmitted to the shipping line before this deadline. If customs clearance is not completed on time, the container cannot be loaded onto the scheduled vessel and will be rolled over to the next voyage.
Closing times vary by port and shipping line, typically falling 24–48 hours before the vessel’s departure. As a professional About SynhopeLogistics | Xinjiang Freight Forwarder, SYNHOPE LOGISTICS provides these key deadlines immediately upon booking, ensuring customs declarations are arranged well in advance to prevent containers from being “rolled” (left behind).
What is SI Cut-off?
The SI (Shipping Instruction) Cut-off is the deadline for submitting and confirming the details required for the Bill of Lading (B/L). By this time, clients must provide all necessary B/L information—such as the details of the consignor and consignee, product description, package count, weight, dimensions, and shipping marks—and confirm the final version of the Bill of Lading.
Modifying B/L information after this deadline incurs amendment fees from the shipping line. Furthermore, the amendment process is time-consuming and can potentially cause delays during customs clearance at the destination port. SYNHOPE LOGISTICS proactively reminds clients to verify their data and finalize all details in a timely manner, helping to avoid the extra costs associated with document amendments.
What is VGM Cut-off?
VGM stands for “Verified Gross Mass” of a container. Under the mandatory requirements of the SOLAS (Safety of Life at Sea) Convention, the verified gross mass of every full container (FCL) intended for export must be submitted to the shipping line; containers without VGM data are not permitted to be loaded onto a vessel.
VGM data can be obtained via two methods: weighing the fully loaded container, or calculating the sum of the cargo weight and the container’s tare weight. The VGM cut-off time is generally earlier than the customs closing time; some shipping lines set a separate deadline for VGM, which may not align with the port or customs closing deadlines.
Sequence of Deadlines: VGM, Documentation, and Cargo Cut-off
In standard operations, the typical chronological order is: VGM cut-off → Documentation cut-off → Cargo cut-off. However, this is not a fixed standard; the specific requirements stated in the booking confirmation shall prevail.
| Item | Definition | Common Deadline | Risk if Missed |
|---|---|---|---|
| VGM Cut-off | Deadline for submitting verified gross mass of container | 24–72 hours before ETD | Container cannot be loaded on vessel |
| SI Cut-off | Deadline for submitting shipping instruction and confirm BL data | 24–48 hours before ETD | Amend fee for BL revision |
| Closing Time | Deadline for customs release information submission | 24–48 hours before ETD | Shipment rolled to next sailing |
Consequences of Missing Deadlines
- Missing the VGM (Verified Gross Mass) deadline: Even if the container has arrived at the port, it will be barred from loading and subsequently “rolled” (left behind). This results in container demurrage charges and additional costs for re-arranging drayage.
- Missing the documentation cutoff (SI/shipping instruction deadline): This necessitates a document amendment process, incurring amendment fees. Furthermore, errors in the Bill of Lading (B/L) data can lead to customs clearance delays at the destination port.
- Missing the cargo cutoff (port closing time): If customs clearance has not been granted, the cargo cannot be loaded onto the vessel. This leads to lost space, storage charges, and delivery delays.
