In ocean freight, booking a vessel is only the beginning of the shipping process. Your cargo must also arrive at the correct terminal, complete export customs procedures, submit shipping instructions and meet all carrier deadlines before the vessel departs.
Two of the most important terms in this process are cut-off time and sailing time.
Although they are closely connected, they refer to different stages of an ocean shipment:
- Cut-off time is the deadline for completing a required shipping activity.
- Sailing time usually refers to the vessel’s scheduled departure or the beginning of the ocean journey.
Missing a cut-off can cause your container to miss the planned vessel, even when the vessel has not yet sailed. Understanding these deadlines helps importers, exporters and manufacturers avoid rollovers, storage charges and supply chain delays.
Cut-Off Time vs Sailing Time: Quick Explanation
| Item | Cut-Off Time | Sailing Time |
|---|---|---|
| Meaning | Deadline for cargo, documents or declarations | Scheduled vessel departure |
| Common abbreviation | CY cut-off, SI cut-off, VGM cut-off | ETD |
| Set by | Shipping line, terminal or local authority | Shipping line and vessel operator |
| Occurs | Before vessel departure | When the vessel leaves the port |
| Main responsibility | Shipper and freight forwarder must meet it | Carrier operates the sailing schedule |
| Risk if missed | Cargo may be rolled to another vessel | Transit and arrival schedule may change |
The easiest way to remember the difference is:
Cut-off time is the shipper’s deadline. Sailing time is the vessel’s schedule.
What Is Cut-Off Time in Ocean Freight?
Ocean freight cut-off time is the latest date and time by which a specific action must be completed for cargo to remain eligible for the booked vessel.
A shipment normally has more than one cut-off. Depending on the shipping line, terminal, port and destination, a booking may include separate deadlines for:
- Container gate-in
- Shipping instructions
- Verified Gross Mass
- Export customs declaration
- Dangerous goods documentation
- Reefer cargo arrangements
- Advance manifest filing
Carrier schedule systems commonly display container gate-in, shipping instruction and VGM deadlines separately because each deadline serves a different operational purpose.
Meeting one deadline does not automatically mean that all requirements have been completed. For example, a container may arrive at the terminal before the CY cut-off but still miss the vessel because the shipping instructions or VGM were submitted late.
Main Types of Ocean Shipping Cut-Off Times
1. CY Cut-Off or Container Gate-In Cut-Off
The CY cut-off, also known as the container yard or gate-in cut-off, is the latest time a loaded export container can enter the designated port terminal.
Before gate-in, the shipper or freight forwarder normally needs to arrange:
- Empty container pickup
- Cargo loading and securing
- Container sealing
- Export customs declaration
- Truck transportation to the terminal
If the truck arrives after the terminal closes the vessel’s receiving window, the terminal may reject the container or require approval for late gate-in.
CY cut-off times can vary according to the terminal, vessel, service route and port conditions. Shippers should always use the deadline shown on the latest booking confirmation rather than relying on a general rule.
2. Shipping Instruction Cut-Off
The shipping instruction cut-off, often called the SI cut-off or documentation cut-off, is the deadline for submitting the information required to prepare the bill of lading.
Shipping instructions usually include:
- Shipper and consignee information
- Notify party details
- Port of loading and discharge
- Final destination
- Cargo description
- Number and type of packages
- Gross weight and measurement
- Container and seal numbers
- Freight payment terms
- Bill of lading requirements
Late or incorrect shipping instructions can delay manifest filing, bill of lading preparation and customs compliance.
Importers and exporters should review company names, addresses, cargo descriptions and destination requirements carefully before submission. Correcting documentation after the carrier’s manifest has been filed may result in amendment fees or customs delays.
3. VGM Cut-Off
The VGM cut-off is the deadline for submitting the Verified Gross Mass of a packed container.
Under SOLAS requirements, the shipper is responsible for providing the verified gross mass of the packed container. The VGM must be available early enough for the terminal and vessel operator to use it when preparing the vessel stowage plan.
A packed container without an accepted VGM may not be loaded onto the vessel.
The verified weight can generally be obtained by:
- Weighing the complete packed container; or
- Weighing the cargo, packaging, pallets and securing materials, then adding the container tare weight using an approved method.
Some terminals may also operate a “No VGM, No Gate-In” policy, meaning the container can be rejected at the terminal entrance when no valid VGM has been submitted.
4. Customs or Manifest Cut-Off
Customs and advance manifest deadlines may occur before the physical cargo cut-off.
Depending on the destination, carriers and freight forwarders may need to submit advance cargo information to customs authorities before loading or before vessel departure.
Common systems include:
- AMS for shipments to the United States
- ISF requirements for US imports
- ACI for Canada
- ENS or ICS2 requirements for the European Union
- Destination-specific advance manifest systems
Because these filings depend on accurate commercial and transportation information, exporters should provide the commercial invoice, packing list and consignee details well before the final documentation deadline.
5. Dangerous Goods Cut-Off
Dangerous goods shipments usually require earlier booking and documentation deadlines.
The shipper may need to provide:
- Material Safety Data Sheet
- Dangerous goods declaration
- UN number
- Proper shipping name
- Hazard class
- Packing group
- Flash point
- Packaging certificates
- Container packing certificate
The shipping line must review and approve the cargo before accepting it. A missing or incorrect dangerous goods document can prevent the container from entering the port or being loaded.
6. Reefer Cargo Cut-Off
Refrigerated containers may have special terminal receiving windows and operational requirements.
Before delivery, the shipper may need to confirm:
- Required temperature
- Ventilation settings
- Humidity settings
- Pre-cooling requirements
- Cold treatment instructions
- Generator requirements during trucking
- Terminal power connection arrangements
Reefer shipments should be coordinated early because late gate-in may affect temperature control and cargo quality.
What Is Sailing Time?
In shipping conversations, “sailing time” can have two different meanings.
Vessel Sailing Time
Vessel sailing time may refer to the scheduled date and time when the vessel leaves the port of loading. This is usually shown as the Estimated Time of Departure, or ETD.
For example:
- ETD Qingdao: August 8
- ETA Los Angeles: August 22
The ETD is the planned departure date, while the ETA is the estimated arrival date.
Ocean Transit Time
Some shippers also use “sailing time” to describe the number of days required for the vessel to travel from the origin port to the destination port.
The more accurate term for this is transit time.
Transit time may include:
- Direct ocean transportation
- Calls at intermediate ports
- Canal passage
- Transshipment waiting time
- Feeder vessel transportation
A direct service usually offers a more predictable transit schedule than a service requiring one or more transshipments. However, actual transit time can still change because of weather, congestion, vessel rotation or operational adjustments.
How Cut-Off Time and Sailing Time Work Together
Cut-off deadlines must occur before the vessel’s ETD because the carrier and terminal need sufficient time to:
- Receive export containers
- Complete security and customs checks
- Confirm container weights
- Finalize cargo manifests
- Plan container stowage
- Move containers to the loading area
- Load and secure containers on the vessel
Consider the following simplified example.
Example Shipping Timeline
A container is booked on a vessel with a Friday ETD.
| Shipping Activity | Example Schedule |
|---|---|
| Cargo ready at factory | Monday |
| Empty container pickup | Tuesday |
| Container loading | Tuesday |
| Export customs declaration | Wednesday |
| Shipping instruction cut-off | Wednesday |
| VGM cut-off | Wednesday or Thursday |
| CY gate-in cut-off | Thursday |
| Vessel ETD | Friday |
This is only an example. Actual deadlines may be earlier or later depending on the shipping line, terminal and trade route.
The booking confirmation and carrier schedule should always be treated as the official reference.
What Happens If You Miss the Cut-Off Time?
Missing a cut-off does not always mean the shipment is cancelled, but it can create serious operational and financial consequences.
Cargo Rollover
The carrier may move the container to the next available vessel. This is commonly known as a rollover.
The next vessel may depart several days later, or much later during peak shipping periods.
Rebooking Charges
The original booking may need to be amended or replaced. Depending on the carrier and rate agreement, rebooking or cancellation charges may apply.
Additional Trucking Costs
If the terminal refuses the container, the truck may need to return it to a warehouse or container yard.
This can result in:
- Additional trucking fees
- Waiting charges
- Driver detention
- Lift-on and lift-off charges
- Overnight container storage
Port Storage
A container that enters the terminal but misses its planned vessel may remain inside the port until another sailing is confirmed.
Terminal storage fees may apply when the container exceeds the permitted free period.
Container Detention
When a container remains outside the terminal longer than the shipping line’s free-time allowance, detention charges may arise.
This can happen when cargo loading, customs clearance or gate-in is delayed after the empty container has been collected.
Customs Amendment
If the export declaration or manifest has already been filed against the original vessel, the documentation may need to be amended.
This can cause additional service charges and processing time.
Delayed Delivery
A missed vessel can affect:
- Production schedules
- Customer delivery commitments
- Retail inventory
- Construction projects
- Seasonal promotions
- Amazon or warehouse appointments
- Downstream trucking and distribution
The total business cost may be much higher than the direct rebooking fee.
Why Can Vessel Sailing Times Change?
Meeting every cut-off does not guarantee that the vessel will depart exactly at the original ETD.
Ocean freight schedules may change because of:
- Port congestion
- Severe weather
- Vessel delays at previous ports
- Berth availability
- Labor disruptions
- Canal congestion
- Equipment or mechanical problems
- Changes to vessel rotation
- Transshipment delays
- Blank sailings
A shipment can meet the terminal cut-off and still experience a delayed ETD. This is why shippers should monitor both the cargo deadlines and the latest vessel schedule.
Cut-Off Time, ETD, ETA and Transit Time
These terms should not be used interchangeably.
| Shipping Term | Meaning |
|---|---|
| Cut-Off Time | Final deadline for completing a shipping requirement |
| ETD | Estimated Time of Departure from the origin port |
| ATD | Actual Time of Departure |
| ETA | Estimated Time of Arrival at the destination port |
| ATA | Actual Time of Arrival |
| Transit Time | Estimated transportation duration between origin and destination |
| Cargo Ready Date | Date when the goods are ready for pickup or loading |
A reliable shipment plan should start with the cargo ready date and work backward from the relevant cut-offs.
How to Avoid Missing an Ocean Freight Cut-Off
Confirm Every Deadline in Writing
Do not ask only for the vessel ETD. Request the complete deadline schedule, including:
- SI cut-off
- VGM cut-off
- Customs cut-off
- CY cut-off
- Dangerous goods cut-off
- Reefer cut-off
Deadlines may be revised when the vessel schedule changes, so the latest booking confirmation should always be checked.
Prepare Shipping Documents Early
Prepare the commercial invoice, packing list, shipping instructions and certificates before the container is loaded.
Early preparation gives the shipper and freight forwarder enough time to identify:
- Incorrect consignee information
- Missing HS codes
- Inconsistent cargo descriptions
- Weight differences
- Destination documentation requirements
- Special customs restrictions
Schedule Factory Loading in Advance
Container loading should not be arranged at the last possible moment.
Allow additional time for:
- Empty container pickup delays
- Factory loading problems
- Cargo quantity changes
- Container inspection
- Truck breakdowns
- Traffic restrictions
- Customs inspections
Complete Customs Clearance Before Gate-In
Export customs problems can prevent the truck from entering the port before the CY cut-off.
Send customs documents to the freight forwarder early and verify whether the cargo requires:
- Export licenses
- Commodity inspection
- Special certificates
- Dangerous goods approval
- Brand authorization
- Additional customs supervision
Leave a Safety Buffer
The official terminal cut-off should not become the shipper’s target arrival time.
Whenever possible, arrange for the container to arrive earlier than the final deadline. A reasonable buffer protects the shipment from traffic, terminal congestion and customs delays.
Monitor Vessel Schedule Changes
Carriers may update ETD, terminal opening times or cut-off dates after the initial booking.
Shippers should monitor the shipment from booking confirmation until the container has been loaded and the vessel has actually departed.
Work With an Experienced Freight Forwarder
A professional freight forwarder coordinates the factory, trucking company, customs broker, terminal and shipping line.
This is especially important for shipments involving:
- Multiple suppliers
- Heavy cargo
- Dangerous goods
- Refrigerated cargo
- Buyer-owned containers
- Door-to-door delivery
- DDP or DDU services
- Transshipment routes

Frequently Asked Questions
Is cut-off time the same as vessel departure time?
No. Cut-off time is a deadline that occurs before vessel departure. The vessel departure time is normally shown as the ETD.
How long before sailing is the CY cut-off?
There is no universal interval. The timing depends on the shipping line, terminal, port, route, cargo type and local operating conditions. Always check the latest booking confirmation.
Can a container enter the port after the CY cut-off?
Normally, the terminal may reject a late container. In some cases, the carrier and terminal may approve late gate-in, but approval is not guaranteed and additional charges may apply.
What happens if the container arrives on time but the VGM is late?
The container may still be prevented from loading. Verified Gross Mass is a condition for loading packed containers covered by the SOLAS requirements.
Can the cut-off time change after booking?
Yes. A cut-off may change when the vessel schedule, terminal plan or port operation changes. Shippers should check for updated booking confirmations and schedule notices.
What is the difference between CY cut-off and SI cut-off?
The CY cut-off is the deadline for delivering the physical container to the terminal. The SI cut-off is the deadline for submitting the cargo and bill of lading information.
Does meeting the cut-off guarantee loading?
No. Meeting the deadline keeps the shipment eligible for loading, but loading may still be affected by customs holds, operational restrictions, vessel capacity, cargo compliance or carrier decisions.
Should I plan according to ETD or cut-off time?
Both are important, but factory pickup, container loading and customs clearance should be planned according to the earliest applicable cut-off—not only the ETD.
Conclusion
Cut-off time and sailing time represent two different parts of the ocean freight process.
- Cut-off time is the deadline for completing cargo, documentation, customs or weight requirements.
- Sailing time refers to the vessel’s scheduled departure or, in some conversations, the ocean transit period.
- Transit time is the estimated number of days required to move cargo from the origin to the destination.
- ETD is the estimated vessel departure date.
A successful ocean shipment requires more than selecting a vessel with a suitable ETD. The shipper must also coordinate cargo readiness, container loading, customs clearance, terminal delivery, VGM submission and shipping documentation.
BRF SHIPPING helps importers and exporters manage these deadlines through complete ocean freight, customs clearance, warehouse loading and door-to-door logistics services.
