Vessel Schedule
Interlink編集部Vessel Schedule
A vessel schedule is planned operational information showing which ports a vessel is expected to call at, in what sequence, and when it is expected to depart from and arrive at each port.
In ocean transport operations, the schedule is reviewed together with the vessel name, voyage, shipping line, service name, port of loading, port of discharge, ETD, ETA, CY cut-off, port rotation, transshipment port, connecting vessel and whether the service is direct or involves transshipment.
For a shipper or cargo owner, it is basic information used to understand when cargo is expected to depart, arrive and become available for use or delivery.
For a freight forwarder, it is management information used to organize the booking, empty-container pickup, vanning, VGM submission, export customs clearance, drayage, CY delivery, B/L issuance, Arrival Notice, D/O procedures, import customs clearance, cargo pickup, domestic delivery and final receipt.
A vessel schedule is planned information, not a confirmed operational result. It may change after booking because of port congestion, severe weather, delay from a previous voyage, fleet adjustment, port rotation change, port omission, blank sailing, rollover or a change to the transshipment connection.
A vessel schedule should therefore not be treated as information that is checked once and then left unchanged. Planned information, revised information, actual events and the cargo's current status must be compared throughout the transport.

Main Information Contained in a Vessel Schedule
| Item | Meaning | Main Operational Use | Review Caution |
|---|---|---|---|
| Vessel name | Name of the vessel expected to carry the cargo | Booking, B/L, tracking and Arrival Notice | The same vessel may operate several voyages |
| Voyage | Voyage number identifying the relevant sailing | Identification of the sailing, port calls, B/L and Arrival Notice | Do not identify the shipment from the vessel name alone |
| Service name | Name used by the shipping line for the route or scheduled service | Port calls, frequency and direct or transshipment structure | Different services between the same ports may have different routes and transit times |
| Port of loading | Port where the cargo is loaded on the vessel | CY delivery, export declaration, B/L and drayage | Confirm the terminal or CY as well as the port |
| Port of discharge | Port where the cargo is discharged from the vessel | D/O, import declaration, cargo pickup and domestic delivery | It may differ from the final place of delivery |
| ETD | Estimated time or date of departure | Export workflow, shipment planning and commercial timing | It is not the actual departure time |
| ETA | Estimated time or date of arrival | Arrival Notice, customs, pickup and delivery preparation | It is not the berthing time, cargo-availability date or delivery date |
| CY cut-off | Deadline for delivery of the laden container to the designated CY | Vanning, customs, drayage and CY-delivery management | It does not automatically move when the ETD changes |
| SI and VGM deadlines | Deadlines for the Shipping Instruction and VGM | B/L preparation, stowage and safety review | Manage them separately from the CY cut-off |
| Port rotation | Sequence in which the vessel calls at ports | ETD, ETA, connection and route review | A change may move a port earlier or later |
| Transshipment port | Intermediate port where the cargo is transferred to another vessel | Connecting-vessel and final-ETA management | Arrival of the first leg does not establish successful connection |
| Connecting vessel | Vessel carrying the cargo on the next transport leg | Final-arrival review for transshipment cargo | Distinguish the planned vessel, confirmed loading and actual departure |
| Direct or transshipment service | Whether the cargo remains on one vessel or transfers during transport | Comparison of lead time, cost and delay risk | Review connection reliability as well as the shortest transit time |
A vessel schedule is not merely a table of ETDs and ETAs. It is integrated management information connecting the vessel, voyage, ports, deadlines, route, connections and cargo operations.
Information Layers Within a Vessel Schedule
| Information Layer | Main Items | Operational Role | Review After a Change |
|---|---|---|---|
| Vessel and voyage information | Vessel, voyage, shipping line and service | Identify the relevant transport sailing | Vessel substitution, voyage change and booking migration |
| Port and route information | Loading port, discharge port, port calls, rotation and transshipment port | Identify the route followed by the cargo | Port omission, rotation change, alternative port and revised route |
| Time information | ETD, ETA, CY cut-off, SI deadline and VGM deadline | Build the export and import workflows | Earlier or later timing and whether deadlines move together |
| Export-operation information | Booking, empty container, vanning, customs, CY delivery and B/L | Manage backward planning for loading | Cargo readiness, permission, documents and loadable status |
| Import-operation information | Arrival Notice, D/O, import customs, cargo pickup, delivery and receipt | Build the process after arrival | Berthing, handling, terminal availability, permission and vehicles |
| Change and delay information | Blank sailing, port omission, port rotation change, rollover and transshipment delay | Identify the difference from the original plan and affected operations | Cause, cargo status, alternative, cost and notice |
| Actual-event information | Actual loading, departure, arrival, handling completion and cargo availability | Replace planned information with actual events | Whether a plan is being mistaken for an actual event |
A schedule change should be analyzed by identifying which information layer changed rather than describing it only as a date change.
Planned, Revised and Actual Information
| Information Type | Typical Example | Operational Use | What It Does Not Establish |
|---|---|---|---|
| Planned information | Booking ETD, ETA, CY cut-off and intended vessel | Build the workflow, quotation and provisional delivery plan | Actual loading, departure or arrival as planned |
| Revised information | Revised ETD, revised ETA, replacement vessel or rotation change | Update operations, documents and related appointments | That the revision is the final change |
| Cargo-status information | Delivered to CY, awaiting loading, held at transshipment port or awaiting terminal availability | Identify where the cargo is and what event is pending | Individual cargo status based solely on the general vessel schedule |
| Actual-event information | Actual loading, departure, arrival or handling completion | Replace the planned event with an actual result | Cargo availability or final delivery based on arrival alone |
| Forecast information | Expected berthing, handling completion or cargo availability | Provide provisional preparation information | A confirmed operational or delivery appointment |
Communications should also distinguish planned, forecast, under-review and confirmed information.
Relationship with the Booking Confirmation
A Booking Confirmation is issued by the shipping line or NVOCC to confirm the reservation information available when the booking is accepted.
It commonly shows the booking number, vessel, voyage, loading port, discharge port, ETD, ETA, CY cut-off, SI deadline, VGM deadline, receiving location, number and type of containers and transshipment information.
The Booking Confirmation is important evidence that the booking was accepted and shows the planned conditions at that time. It does not necessarily guarantee that the vessel schedule will remain unchanged until completion of carriage.
However, the fact that the schedule is provisional does not permit the freight forwarder to omit later review or communication. The individual booking, revised notices, vessel status, terminal information and cargo status should continue to be reviewed.
| Review Stage | Booking Confirmation Information | Additional Review | Operational Purpose |
|---|---|---|---|
| When issued | Vessel, voyage, ports, ETD, ETA, deadlines and receiving location | Cargo conditions, dangerous goods or special-cargo approval and freight terms | Establish the initial export workflow |
| Before the CY cut-off | Latest cut-off, SI and VGM deadlines and receiving location | Terminal instructions, vessel change and gate restrictions | Prepare the cargo in a loadable condition |
| Before loading | Intended vessel, voyage and revised notice | Loading plan, rollover, port omission and blank sailing | Confirm loading feasibility |
| After departure | Booked vessel and route | Actual loading, departure, transshipment port and connecting vessel | Confirm that the individual cargo is moving |
| Before arrival | Discharge port and ETA | Berthing, handling, Arrival Notice and expected cargo availability | Prepare import and delivery operations |
Vessel-Schedule Information Lifecycle
| Stage | Information to Review | Operational Purpose | What Cannot Yet Be Treated as Confirmed |
|---|---|---|---|
| Quotation and proposal | Route, direct or transshipment service, estimated ETD and ETA, frequency and lead time | Compare transport options, cost and delivery timing | Loading on a particular vessel or confirmed arrival |
| Booking | Vessel, voyage, ETD, ETA, CY cut-off, receiving location and deadlines | Make the reservation and build the export workflow | That no change will occur during carriage |
| Cargo preparation | Empty container, vanning, documents, cargo approval and customs schedule | Plan backward from the CY cut-off | That cargo preparation alone confirms loading |
| Before the CY cut-off | Latest deadline, receiving location, gate restriction, export permission and vehicle | Complete the cargo-side loading requirements | Automatic extension because the vessel is delayed |
| Before loading | Vessel status, blank sailing, port omission, port rotation change and rollover | Confirm loading and document information | Actual loading based only on the booking |
| After departure | Actual loading, departure, transshipment port, connecting vessel and final ETA | Track the actual movement of the cargo | Final arrival based only on first-leg departure |
| Before arrival | ETA, berthing, handling, Arrival Notice, D/O and customs preparation | Prepare customs, pickup and delivery | Cargo availability or delivery from the ETA alone |
| After arrival | Actual arrival, berthing, handling completion, terminal availability, import permission and pickup appointment | Confirm the expected delivery date | Cargo availability based solely on vessel arrival |
Relationship with ETD and ETA
ETD and ETA are critical time elements within the vessel schedule.
ETD is the estimated departure time or date, and ETA is the estimated arrival time or date. Neither directly establishes actual loading, departure, berthing, handling, cargo availability or final delivery.
| Information | Meaning | Related Operations | Information That Must Remain Separate |
|---|---|---|---|
| ETD | Estimated departure | Export workflow, shipment plan and connection plan | CY cut-off, actual shipment date and actual departure |
| Actual Departure | Time when the vessel actually departed | Commencement of the voyage and updated arrival outlook | Actual loading of the individual cargo |
| ETA | Estimated arrival | Customs, D/O, pickup and delivery preparation | Berthing, handling completion, cargo availability and delivery |
| Actual Arrival | Time when the vessel actually arrived at the port | Review of berthing and handling | Terminal availability or pickup date |
| Cargo-availability date | Date on which the cargo or container can be collected | Drayage, customs and delivery | ETA or actual arrival |
| Expected delivery date | Date that satisfies customs, pickup, delivery and receiving requirements | Final delivery and customer communication | ETA |
Relationship with the CY Cut-off
The CY cut-off is one of the most important vessel-schedule items for export operations.
It is the deadline for delivery of the laden export container to the CY designated by the shipping line or terminal. It is separate from the ETD and does not necessarily move later when the vessel is delayed.
| Schedule Situation | Effect on ETD | Possible Effect on CY Cut-off | Operational Response |
|---|---|---|---|
| Vessel delay | Moves later | May remain unchanged, move later or be individually revised | Confirm the individual booking and terminal instruction |
| Earlier port rotation | May move earlier | May also move earlier | Recalculate vanning, customs and drayage |
| Vessel substitution | Changes to the replacement vessel's schedule | The deadline or receiving location may change | Update all operations from the revised booking |
| Blank sailing | The intended sailing no longer operates | Changes to the next sailing's deadline | Review the next vessel, alternative route and storage |
| Loading-port omission | The vessel cannot load at the intended port | Confirm the deadline for another port or later vessel | Review alternative loading, next vessel and export declaration |
Direct and Transshipment Services
| Comparison | Direct Service | Transshipment Service | Review Caution |
|---|---|---|---|
| Vessel structure | The cargo normally remains on one vessel | The cargo is transferred to another vessel | Review each vessel and voyage in a transshipment route |
| Main times | Loading-port ETD and discharge-port ETA | First-leg ETD, transshipment-port ETA, connecting-vessel ETD and final ETA | Do not confuse an intermediate ETA with the final ETA |
| Main delay risk | Vessel delay, port congestion, severe weather and handling delay | First-leg delay, missed connection, waiting for the next vessel and connection change | A delay of several hours may be amplified into several days |
| Tracking | Primarily follows one vessel movement | Requires arrival, discharge, connection, loading and departure review | Distinguish the planned connection from actual loading |
| Customer communication | Explains the vessel position and discharge-port ETA | Explains the cargo location, connection status and next vessel | Do not describe first-leg departure as successful final transport |
Main Types of Vessel-Schedule Change
| Change or Delay | Description | Mainly Affected Information | First Point to Confirm | Related Article |
|---|---|---|---|---|
| ETD or ETA change | Departure or arrival moves earlier or later | CY cut-off, customs, pickup, delivery and receipt | Cause, actual event and effect on other deadlines | ETD and ETA |
| Vessel or voyage change | The intended vessel or voyage changes | Booking, B/L, Shipping Instruction and Arrival Notice | Revised booking and actual loading vessel | Schedule Change After Booking |
| CY cut-off change | The container-delivery deadline changes | Vanning, customs, drayage and CY delivery | Latest deadline, receiving location and notice time | Relationship Between CY Cut-off and Vessel Schedule |
| Blank sailing | The intended sailing is cancelled or suspended | Next vessel, booking, delivery timing and storage | Replacement sailing and booking transfer | Blank Sailing |
| Rollover | The vessel operates but individual cargo is not loaded | Shipment date, next vessel, B/L and costs | Loadable status, cause and next-vessel space | Rollover |
| Port omission | The vessel operates but does not call at a specific port | Loading port, discharge port, customs location and delivery route | Affected port, alternative port and cargo status | Port Omission |
| Port rotation change | The order of port calls changes | ETD, ETA, CY cut-off and connections | Whether the relevant port moves earlier or later | Port Rotation Change |
| Transshipment delay | The cargo misses the intended connecting vessel | Connecting vessel, final ETA and delivery | Cargo status, next vessel and actual loading | Transshipment Delay |
| Typhoon or severe weather | Voyage, berthing, handling, CY or delivery is interrupted | ETD, ETA, handling, cargo availability and delivery | Which operation is currently suspended | Delay Due to Typhoon and Bad Weather |
| Vessel arrival delay | The vessel will call at the port but arrival or post-arrival handling is delayed | Berthing, handling, terminal availability and cargo pickup | Vessel position and expected cargo availability | Vessel Arrival Delay |
Basic Vessel-Schedule Review Flow
- Identify the cargo: Confirm the shipper or cargo owner, booking number, B/L number, container number and cargo.
- Identify the vessel: Confirm the vessel, voyage and service name.
- Confirm the route: Review the loading port, discharge port, port calls, transshipment port and final destination.
- Confirm planned times: Review the ETD, ETA, connecting-vessel ETD and final ETA.
- Confirm export deadlines: Review the CY cut-off, SI deadline, VGM deadline and cargo-approval deadlines.
- Confirm current cargo status: Determine whether the cargo is before CY delivery, in the CY, loaded, at sea, at a transshipment port or at the discharge port.
- Review changes: Check for vessel substitution, blank sailing, port omission, port rotation change or rollover.
- Confirm actual events: Review actual loading, departure, arrival, handling completion and cargo availability.
- Review export-document effects: Confirm the Shipping Instruction, B/L, export declaration, L/C requirements and certificates.
- Review import-operation effects: Confirm the Arrival Notice, D/O, import declaration, pickup and delivery.
- Recalculate delivery: Use cargo availability, vehicle capacity and receiving conditions rather than the ETA alone.
- Review costs and physical damage: Confirm rescheduling costs, storage, Demurrage, Detention and possible physical cargo damage.
- Notify the relevant parties: Separate confirmed, planned, under-review and next-update information.
Different Use on the Export and Import Sides
| Information | Export-Side Purpose | Import-Side Purpose | Common Caution |
|---|---|---|---|
| ETD | Manage shipment, documents and connection timing | Review commencement of carriage and arrival outlook | Keep it separate from actual departure |
| ETA | Communicate expected arrival to the buyer or overseas party | Prepare customs, cargo pickup and delivery | Keep it separate from the delivery date |
| CY cut-off | Plan cargo preparation, customs and drayage backward | Use it when reviewing the cause of a shipment delay | Manage it separately from the ETD |
| Vessel and voyage | Use for the booking, Shipping Instruction, B/L and export declaration | Use for the Arrival Notice, D/O and import declaration | Remove obsolete information after a change |
| Transshipment and connection | Review expected arrival and any transshipment conditions | Review final ETA and route reliability | Do not rely only on the first leg |
| Change notice | Reschedule vanning, customs, CY delivery and documents | Reschedule the D/O, customs, pickup and delivery | Preserve receipt and communication times |
Relationship with Additional Costs
| Cost Item | Typical Situation | Documents and Records | Allocation Consideration |
|---|---|---|---|
| Drayage rescheduling | The CY cut-off, vessel or receiving location changes | Vehicle record, change notice and cancellation terms | Notice time, instructing party and possible avoidance |
| Warehouse storage | Shipment or delivery is postponed | Storage period, invoice and change history | Whose circumstances extended storage |
| Waiting or cancellation charge | A vehicle, handling operation or appointment changes | Waiting record, booking record and notice time | Whether the cost could have been avoided |
| Document-amendment charge | The vessel, voyage, port or date changes | Amendment request, history and invoice | Cause of amendment and document responsibility |
| Demurrage | The import container remains in the terminal beyond Free Time | Terminal availability, pickup, Free Time and charge details | Commencement, suspension, waiver and delay cause |
| Detention | The container is returned after the applicable Free Time | Pickup, return, Free Time and delivery record | Return feasibility, receiving conditions and depot requirements |
| Receiving-appointment change | The ETA or cargo-availability date changes | Appointment, amendment history and charge terms | Whether it is a transport cost or commercial cost |
The existence of a schedule change and the right to recover the resulting cost from the shipping line, NVOCC, freight forwarder, shipper or cargo owner are separate issues.
The contract, B/L terms, booking conditions, cause, entrusted work, nature and place of the cost, instructions, approval and possible mitigation must be reviewed.
Relationship with Marine Cargo Insurance
A vessel-schedule change or arrival delay alone may not be covered by ordinary marine cargo insurance.
Where severe weather, transshipment handling, extended storage, container damage, temperature deviation or another accident causes physical cargo damage, the physical loss must be reviewed separately from the delay.
| Situation | Main Issue | Documents and Records | Initial Action |
|---|---|---|---|
| Only the ETA moves later | Delay or commercial loss | Vessel status, change notice and contract terms | Do not assume insurance coverage; review “Delay and Marine Cargo Insurance” |
| Wet damage is discovered after severe weather | Physical cargo damage | Photographs, external condition, container condition and receipt record | Notify the insurer, carrier and relevant parties promptly |
| Damage is found after transshipment-port delay | Handling or storage damage | Transfer history, handling record, seal and survey | Investigate the probable transport leg and cause |
| Temperature deviation affects reefer cargo | Combined delay, equipment and power-management issue | Temperature, power, alarm and equipment records | Review physical damage separately from the delay |
Cases That Commonly Cause Operational Problems
| Case | Main Issue | Documents to Check | Decision Point | Initial Response |
|---|---|---|---|---|
| A different voyage of the same vessel is reviewed | Wrong sailing identified | Booking, voyage, ports and dates | Whether the vessel name was used without the voyage | Reidentify the sailing from the booking number and voyage |
| The ETD moves later and the CY cut-off is assumed to move later | Confusion between separate deadlines | Revised booking, terminal instruction and gate record | Whether an actual cut-off amendment was issued | Confirm the latest deadline and rebuild the delivery workflow |
| The ETA is communicated as the delivery date | Confusion between arrival and cargo availability | ETA, handling, customs, pickup and delivery schedule | Whether post-arrival operations were considered | Recalculate the expected delivery date |
| No further review occurs after the Booking Confirmation | Revised notice or vessel change is missed | Notice history, revised booking and vessel status | When the change could have been identified | Update the information and notify the parties |
| First-leg departure is communicated as confirmation of final arrival | Transshipment connection not reviewed | Transshipment port, connecting vessel, loading and departure | Whether the connection has actually been completed | Confirm cargo status and final ETA |
| The draft B/L still shows the replaced vessel | Document does not match actual transport | Revised booking, draft B/L and actual loading | Whether the document matches the actual vessel and voyage | Correct the vessel, voyage and shipment date |
| A port rotation change moves the ETD earlier | Insufficient time for the CY cut-off and customs | Revised schedule, cut-off and operational plan | Whether the cargo can meet the earlier deadline | Review cargo preparation and an alternative vessel in parallel |
| The vessel arrives but the handling date remains uncertain | Difference between ETA and cargo availability | Berthing, handling, terminal and cargo-availability information | Which operation is delayed | Do not confirm pickup or delivery |
| The shipping line website and overseas agent provide different information | Different update timing or information level | Update time, booking and cargo status | Whether the information is general service data or cargo-specific data | Request an individual-booking response from the line or NVOCC |
| The change notice is forwarded without explaining its effect | Operational impact remains unidentified | Notice, workflow, customs, vehicle and receiving appointment | Whether each party knows what must change | Issue a revised notice showing affected items and decisions |
Freight Forwarder Involvement
The five classifications used in this article are not established by law or industry-wide consensus. They serve as an analytical framework within this series to clarify the scope of freight forwarder involvement.
| Classification | Main Vessel-Schedule Involvement | Typical Responsibility Review | Key Documents and Facts | Caution |
|---|---|---|---|---|
| Simple Intermediary | Communicates planned and revised information received from the shipping line or NVOCC | Whether entrusted inquiries and communications were performed accurately and promptly | Receipt time, inquiry history, transmission record and response | This role does not itself guarantee the vessel, ETD, ETA or delivery date |
| Cargo Transportation Service Provider | Coordinates customs, drayage, CY delivery or domestic delivery within the contracted segment | Scope of contracted transport and related operations | Quotation, transport agreement, workflow, work instruction and change history | Responsibility does not automatically extend to operational decisions outside the contracted segment |
| NVOCC / House B/L Issuer | Manages the vessel, route, connection and arrival schedule as the carrier under the House B/L | Notice, alternative arrangement and contractual obligations as the Contracting Carrier | House B/L, applicable terms, Master Booking, route and change notices | Distinguish the Actual Carrier's operation from the NVOCC's contractual responsibility |
| Door-to-Door Single Contractor | Integrates pickup, export, ocean carriage, import, cargo pickup, delivery and final receipt | Contracted segments, delivery commitment and rearrangement response | Integrated transport agreement, workflow, delivery conditions, change history and cost approval | Contractual status may remain even where physical operations are subcontracted |
| Agent / Coordinator for Specific Operations | Coordinates specified booking, CY delivery, customs, D/O or delivery-schedule operations | Specific entrusted tasks and reporting obligations | Work instruction, email, booking, operational record and response history | Responsibility for a specified task does not automatically extend to the entire transport |
Contractual status, the actual scope of entrusted work, physical operations, business attributes, names appearing on transport documents, insurance status, applicable terms and mandatory law must be examined separately from the Standard Five Classifications. These matters do not constitute a sixth classification or any additional classification.
It is necessary to identify who is the Contracting Carrier, who is the Actual Carrier, who obtained the booking, who confirmed the vessel, voyage, ETD, ETA and CY cut-off, who arranged vanning, customs clearance and drayage, and who received each schedule change notice.
Responsibility cannot be determined solely from a party's description as a shipping line, NVOCC, prime freight forwarder, overseas agent, customs broker or delivery provider. The contract, transport documents, applicable terms, entrusted tasks, review time, notice time and response after the change became known must be examined.
Information to Share with the Shipper, Cargo Owner and Other Parties
| Party | Information to Share | Decision Required by That Party | Communication Caution |
|---|---|---|---|
| Shipper | Vessel, voyage, ETD, CY cut-off, change and loading outlook | Cargo preparation, alternative vessel, buyer communication and cost approval | Distinguish the plan from actual loading |
| Cargo owner | Vessel, ETA, berthing, handling, cargo availability and delivery outlook | Inventory, sales, production, delivery and receiving arrangements | Do not communicate the ETA as the delivery date |
| Shipping line or NVOCC | Affected booking, review items and cargo-specific questions | Vessel, space, connection, change and alternative | Request an individual-booking response rather than only general schedule information |
| Customs broker | Vessel, voyage, loading port, discharge port, ETD, ETA and revision history | Declaration, amendment, inspection and permission planning | Clearly withdraw obsolete information |
| Warehouse or vanning site | CY cut-off, work date, empty container and delivery plan | Labour, storage, operation and dispatch | Do not confirm work solely from an unconfirmed vessel |
| Drayage provider | Empty container, vanning, CY, deadline and revised plan | Vehicle, waiting, cancellation and rescheduling | Preserve notice time and cancellation conditions |
| Overseas agent | Vessel, connection, ETA, Arrival Notice and cargo status | Consignee communication, customs, D/O and delivery | Distinguish a candidate vessel from actual loading |
| Delivery location | Provisional delivery outlook, reason for change and next update | Receiving slot, labour, storage and production planning | Do not communicate an unconfirmed ETA as a delivery commitment |
Common Misunderstandings
| Misunderstanding | Actual Approach | Practical Caution |
|---|---|---|
| A vessel schedule is confirmed information | It is planned information and may change during transport | Continue reviewing revisions and actual events |
| The same vessel name means the same sailing | The same vessel may operate several voyages | Confirm the vessel and voyage together |
| No further review is required after the Booking Confirmation | The vessel, deadlines and route may change after booking | Review again before loading, after departure and before arrival |
| A later ETD automatically extends the CY cut-off | The ETD and CY cut-off are managed separately | Confirm the revised booking or terminal instruction |
| ETA is the cargo-availability date | ETA is the vessel's estimated arrival | Confirm berthing, handling, terminal availability and import permission |
| ETA is the delivery date | Pickup, delivery and receiving conditions remain separate | Recalculate the expected delivery date |
| First-leg departure confirms final arrival | A transshipment service still requires loading on the connecting vessel | Confirm connection, actual loading and final ETA |
| The shipping line website shows the status of the individual cargo | General service information may differ from cargo-specific status | Request booking, B/L or container-level confirmation |
| Forwarding the change notice completes the freight forwarder's response | The effect on documents, customs, vehicles and delivery must be reviewed | Identify the required decision and responsible party |
| All delay costs are payable by the shipping line or freight forwarder | Allocation depends on the contract, cause, cost item, instructions and mitigation | Separate the existence of the cost from recoverability |
Example 1: A Different Voyage of the Same Vessel Is Reviewed
Assume that a container is booked from Yokohama to Singapore. The operator searches the shipping line website by vessel name and mistakenly uses the preceding voyage of the same vessel.
The incorrectly selected voyage has a Wednesday ETD, while the booked voyage has a Saturday ETD. The operator informs the shipper of the Wednesday departure, and the overseas side arranges warehouse receiving and delivery using that information.
The error is discovered when the voyage shown on the Booking Confirmation differs from the voyage shown in the draft B/L. A delivery-appointment amendment charge of JPY 50,000 is incurred.
The vessel name alone does not identify the relevant sailing. The booking number, voyage, loading port, discharge port and ETD must be reviewed together.
The freight forwarder should determine which source was used, whether the Booking Confirmation was reviewed and when the corrected information was sent to the shipper and overseas party.
The individual vessel and voyage linked to the booking should be used rather than the first sailing displayed in a general search result.
Example 2: A Later ETD Is Mistaken for an Extended CY Cut-off
Assume that export cargo from Tokyo to North America has an original Thursday ETD and a Monday 4:00 p.m. CY cut-off.
The shipping line website later shows a Saturday ETD. The shipper and freight forwarder assume that the CY cut-off will also move to approximately Wednesday.
However, the individual booking retains the Monday 4:00 p.m. cut-off. The container arrives at the CY on Tuesday morning, and no late gate is approved. The cargo is not loaded on the intended vessel.
The shipper argues that the cargo should have been accepted because the vessel was delayed by two days and requests payment of the resulting delay and emergency-airfreight cost.
The central issue is whether the ETD and CY cut-off were separately reviewed. A later vessel schedule does not necessarily change terminal receiving, stowage or yard deadlines.
The individual booking, cut-off notice, communication to the shipper, vehicle instruction and gate record should be arranged chronologically.
After a schedule revision, the ETD, CY cut-off, SI deadline, VGM deadline and receiving location must be reconfirmed separately.
Example 3: ETA Is Confirmed as the Delivery Date
Assume that imported machinery is scheduled to arrive at Kobe on October 8. The freight forwarder confirms factory delivery for October 9 based on the shipping line's ETA.
The vessel reaches the port area on October 8 but does not berth until October 10 because of congestion. Handling is completed on October 11, the cargo becomes available on October 12 and a suitable heavy vehicle is not available until October 14.
The delivery location had arranged labour for October 9, resulting in a receiving-appointment amendment charge of JPY 80,000.
ETA is the estimated vessel arrival, not the berthing, handling, terminal-availability, D/O, import-permission, vehicle or delivery date.
The freight forwarder may use the ETA for a provisional outlook, but final delivery requires review of berthing, handling, cargo availability, import permission, pickup, vehicle capacity and receiving conditions.
The vessel ETA, cargo-availability outlook, provisional delivery date and confirmed delivery date should be communicated separately.
When to Consult a Maritime Lawyer
Routine vessel-status review, schedule amendment or delivery rescheduling may not require immediate legal advice. Consultation with a lawyer experienced in maritime transport should nevertheless be considered in the following situations:
- The parties dispute whether a particular vessel, ETD, ETA or delivery date was guaranteed
- An incorrect schedule notice results in a substantial claim for alternative transport, contractual penalties or business interruption
- The responsibilities of the shipping line, NVOCC, prime freight forwarder, overseas agent, shipper or cargo owner are complex
- House B/L or Master B/L provisions concerning route change, alternative port, limitation or exclusion of liability are disputed
- A Booking Confirmation or email is alleged to constitute a transport guarantee or special agreement
- An L/C shipment deadline, B/L date, port of loading, port of discharge or transshipment term is affected
- The receipt time, communication time or duty to review the schedule is disputed
- Demurrage, Detention, storage or alternative transport costs are substantial
- A claim-notice deadline, objection period or time bar is approaching
- A party requests execution of an admission of liability, indemnity agreement, settlement or waiver
The Booking Confirmation, revised booking, vessel schedule, shipping line notices, terminal instructions, cargo tracking, B/L, customs records, vehicle and delivery appointments, additional costs and communications should be arranged in chronological order.
Decision Checklist
| Review Stage | Party to Contact | Point to Confirm | Action if a Problem Exists |

| Before loading | Shipping line or NVOCC | Vessel status, blank sailing, port omission, rollover and expected loading | Confirm the replacement vessel and document changes |
| After departure | Shipping line, NVOCC or overseas agent | Actual loading, departure, transshipment port and connecting vessel | Request cargo-specific confirmation |
| During transshipment | Shipping line, NVOCC or overseas agent | Arrival, discharge, connection, actual loading and departure | Distinguish the planned connection from actual loading |
| Before arrival | Shipping line, NVOCC, overseas agent and customs broker | ETA, berthing, handling, Arrival Notice and D/O | Communicate a provisional cargo-availability and delivery outlook |
| After arrival | Terminal, customs broker and delivery provider | Handling completion, terminal availability, import permission, pickup and vehicle | Confirm the expected delivery date |
| When a change notice is received | Notice issuer and related service providers | Affected booking, changed item, reason, notice time and operational effect | Separate confirmed and unresolved information |
| When additional costs arise | Contractual counterparty, service provider and shipper or cargo owner | Cost item, cause, amount, instruction, approval, terms and mitigation | Obtain quotations and approvals and preserve evidence |
| When cargo damage is suspected | Shipping line, NVOCC, insurer and surveyor | Damage, cause, photographs, temperature, seal and discovery time | Handle physical damage separately from the delay |
| When a liability dispute arises | Contractual counterparty, insurer and maritime lawyer | Contractual status, entrusted work, chronology, terms, loss and deadlines | Do not admit liability immediately; preserve the records |
Summary
A vessel schedule is planned operational information combining the vessel, voyage, shipping line, service, loading port, discharge port, ETD, ETA, CY cut-off, port rotation, transshipment port and connecting vessel.
It is not a confirmed operational result. It may change after booking because of port congestion, severe weather, fleet adjustment, blank sailing, rollover, port omission, port rotation change or a revised transshipment connection.
Planned information, revised information, cargo-status information and actual-event information should be kept separate. The vessel and voyage linked to the individual booking should be used rather than the vessel name alone.
On the export side, the ETD must be reviewed together with the CY cut-off, SI deadline, VGM deadline, customs, drayage and actual loading. On the import side, the ETA must be reviewed together with berthing, handling, the D/O, import customs, cargo pickup, vehicle capacity and receiving conditions.
For transshipment cargo, the first-leg vessel is not sufficient. The transshipment port, connecting vessel, connecting ETD, actual loading and final ETA must also be confirmed.
The freight forwarder should not merely forward a schedule-change notice. It should identify the effect on deadlines, documents, operations, delivery and costs and communicate confirmed, planned and under-review information separately.
The responsibility of a freight forwarder cannot be determined solely from its involvement in the vessel schedule. Its status as the Contracting Carrier or Actual Carrier, its position under the Standard Five Classifications, the actual scope of entrusted work, transport documents, applicable terms, review time, notice time and response after the change became known must be examined separately.
The existence of additional costs and the right to recover those costs from the shipping line, NVOCC, freight forwarder, shipper, cargo owner or another party are separate issues. Delay alone must also be distinguished from physical cargo damage.
