Forwarder Response Policy in Cases of Unknown Cause of Accident
Interlink編集部Overview
In cargo incidents, the cause of the accident is not always clear at the time of discovery. Even if it is known that the cargo is damaged, wet, or short in quantity, it may be unclear where, why, or under whose custody the damage occurred.
In freight forwarder practice, what is important is not "doing nothing because the cause is unknown," but rather "managing the unknown cause situation." As time passes with the cause unknown, evidence may be lost, notification deadlines missed, survey opportunities lost, and it becomes difficult to claim compensation from carriers or NVOCCs.
This article organizes how freight forwarders should conduct fact-finding, evidence preservation, stakeholder notification, insurance company response, and shipper explanations when the cause of the incident is unknown.

Three Types of "Unknown"
When the cause of an incident is unknown, in actual logistics practice, it needs to be considered in three categories.
First, the transport segment is unknown. It is unclear whether the incident occurred during sea transport, CFS operations, port stevedoring, domestic delivery, or post-delivery storage.
Second, the cause of damage is unknown. It may be unclear whether the damage was caused by external force, inadequate packing, the cargo’s inherent nature, temperature and humidity mismanagement, or cargo collapse.
Third, the responsible party is unknown. There may be multiple possibilities for the cause or location, and it is unclear whether the shipping line, NVOCC, freight forwarder, warehouse operator, delivery company, or cargo owner is responsible.
Confusing these three leads to incorrect responses. Attempting to assign responsibility when the segment is unknown, or prematurely deciding insurance coverage when the cause is unknown, will complicate later explanations.
Three Classifications of Unknown Causes and Response Policies
| Category | Meaning | Documents to Check | Main Notification Recipients | Practical Response |
|---|---|---|---|---|
| Unknown Transport Segment | It is unclear whether the incident occurred at the export side, sea transport, CFS, CY, warehouse, delivery, or post-delivery storage. | B/L, House B/L, Master B/L, POD, receipts, devanning records, warehouse receipt records, delivery records, photos | Shipping lines, NVOCC, CFS, warehouse operators, delivery companies, overseas agents, insurance companies | Without determining the incident segment, send rights preservation notifications to all possibly involved parties. |
| Unknown Cause of Damage | It is unclear whether the cause is external force, cargo collapse, inadequate packing, inherent cargo nature, temperature/humidity issues, condensation, or poor storage. | Photos, videos, packing materials, temperature logs, container interior photos, Survey Report, pre-shipment inspection records | Shipper, insurance company, surveyor, warehouse operators, delivery companies, carriers | Do not speculate on the cause; prioritize evidence preservation and confirmation of whether a survey is necessary. |
| Unknown Responsible Party | There are multiple possible accident segments or causes, and responsibility cannot be determined. | Contracts, B/L terms, trade terms, work instructions, emails, POD, accident photos, stakeholder responses | Shipper, NVOCC, actual carrier, warehouse operators, delivery companies, insurance companies, and lawyers if necessary | Do not admit responsibility; organize the roles of parties, contractual relationships, and points under which custody was held. |
What Happens When Time Passes While the Cause Remains Unknown
Even if the cause is unknown, time does not stop.
Deadlines for damage notification after cargo delivery, notification conditions under B/L terms, statutes of limitations for suing carriers, accident notifications to marine cargo insurance and freight forwarder liability insurance, and whether to arrange a survey all become issues even before the cause is identified.
As time passes, cargo is moved, packing materials discarded, opportunities to photograph are lost, containers returned, and warehouse and delivery records become difficult to verify.
Therefore, even if the cause is unknown, it is necessary first to send rights preservation notifications to relevant parties, preserve evidence, and secure investigation opportunities.
Waiting to notify "after the cause is known" can be too late. It is crucial, precisely because the cause is unknown, to notify first and secure entry to investigation.
What to Do First Is Not Cause Estimation but Document Fixation
The first action to take in the event of an unexplained accident is not to speculate on the cause. First, secure the documentation.
Secure the date and time of discovery, place of discovery, discoverer, cargo condition, photos, videos, delivery receipts, POD, devanning records, warehouse entry records, delivery records, B/L, House B/L, Master B/L, Invoice, and Packing List.
At this stage, prematurely concluding that "the shipping line is at fault," "the packaging is faulty," or "the delivery company made a mistake" will skew the collection of necessary materials.
When the cause is unknown, it is important to broadly collect documents that can be verified later while keeping multiple possibilities open.
Narrowing Down the Section of Occurrence
Next, narrow down the section where the damage likely occurred.
Check sequentially if the damage might have occurred on the export side, during ocean transport, at the CFS or CY, during domestic delivery, or after delivery.
For FCL cargo, container numbers, seal numbers, vanning records, devanning records, container exterior, and interior photos are important.
For LCL cargo, CFS receiving records, sorting records, records of the co-load destination, import CFS handling records, and delivery company pickup records are important.
Even if the occurrence section cannot be definitively narrowed down, organizing which sections are more or less likely significantly helps in explaining to the shipper and dealing with insurance companies.
Narrowing Down the Cause of Damage
Alongside narrowing down the occurrence section, investigate the possible causes of damage.
For physical damage, check for external dents, cargo shifting, insufficient securing, drops, impacts, or handling errors. For water damage, check seawater, rainwater, condensation, moisture from the container floor, or moisture inside the packaging.
For rust, mold, discoloration, odor transfer, or quality deterioration, review cargo-specific characteristics, packaging deficiencies, pre-shipment condition, temperature and humidity control, transportation duration, and storage conditions.
If you describe the damage merely as a "transportation accident" while the cause is unknown, it may be difficult later to revise this if packaging faults or cargo intrinsic properties are discovered.
In the initial stage, it is safer to limit descriptions to expressions such as "damage discovered during transport," "abnormalities confirmed after delivery," or "damage under cause investigation."
Notification to Related Parties Even if Cause is Unknown
Even if the cause is unknown, consider notifying related parties.
This may include carriers, NVOCCs, shipping lines, CFS, warehouse operators, delivery companies, overseas agents, and insurance companies — anyone potentially involved in the matter — in order to preserve rights.
In notification, it is important not to assign fault.
For example, the notification might say, "Damage has been discovered, and the cause and section of occurrence are currently under investigation. We hereby notify you for the purpose of preserving rights."
Sending notification without knowing the cause is not about blaming others but is a practical step to secure opportunities for further investigation later.
How to Explain to the Shipper
Shippers may demand a quick response even if the cause is unknown.
At such times, the freight forwarder should not just say "We do not know," nor should they explain unknown facts as if they do.
In actual logistics practice, the explanation is as follows.
"At this point, the section where damage occurred and the cause are not yet determined. We will first check receiving records, photos, POD, devanning records, delivery records, and whether notification to the insurance company is required, and then organize likelihoods."
"While we cannot assign responsibility at this unknown cause stage, we will proceed with notification to involved parties and preserving evidence."
"Based on investigation results, we will organize response policies toward the carrier, NVOCC, delivery companies, and insurance companies."
Admitting the cause is unknown while concretely communicating what is being checked is important.
Sample Notification Text to Carriers and NVOCC
When notifying carriers or NVOCC, avoid assigning responsibility and clearly state that the investigation is ongoing.
In Japanese, the following expression can be used:
「本件貨物について損傷が確認されました。現時点では発生区間および原因は調査中ですが、権利保全のため通知いたします。関係する配送記録、搬出入記録、取扱記録の保全をお願いいたします。」
In English, the following expression is practical for actual use:
We hereby notify you that damage to the subject cargo has been reported. The cause and place of occurrence are currently under investigation. We reserve all rights and request that you preserve all relevant records.
For a more cautious phrasing, you may write:
This notice is issued for the purpose of preserving our rights and shall not be construed as an admission of liability or as a determination of the cause of loss.
At the unknown cause stage, wording that avoids definitive statements is important.
How to Explain to Insurance Companies
If marine cargo insurance or freight forwarder liability insurance is involved, initial accident notification to the insurance company may occur while the cause is still unknown.
Communicate to the insurance company separating confirmed facts from unconfirmed points, without determining the cause.
For example: "Damage was discovered after delivery," "There are minor dents on the exterior," "No remarks are present on the delivery receipt," "Opening photos have been taken," "We would like to confirm whether a survey is required."
Notifying the insurance company at the unknown cause stage does not finalize an insurance claim. It is an entry step to arrange surveys, preserve evidence, and check the possibility of recovery early.
How Far to Investigate Before Treating as Unknown Cause
Not all accidents will have a clearly identifiable cause.
Even after reviewing certain documentation, it may be impossible to specify the occurrence section or cause. In such cases, a decision to classify as an unknown cause may be necessary.
However, before handling an incident as unknown cause, the following minimum checks should be completed.
- Have you checked the shipment documents, B/L, Packing List, and Invoice?
- Have you checked the delivery receipt, POD, devanning record, and warehouse entry record?
- Have you checked photos, videos, and survey reports?
- Have you notified related parties and requested preservation of records?
- Have you confirmed whether notification to cargo insurance or liability insurance is required?
- Have you reviewed responses from carriers, NVOCC, delivery companies, and warehouse operators?
- Have you considered the balance between the amount of damage and investigation costs?
If the cause cannot be identified even after these checks, the case is handled as "cause unknown," and business decisions such as insurance handling, settlement, internal absorption, or claim abandonment are considered.
The important point is not to label the cause as unknown without any investigation, but to document the scope of what has been confirmed and what has not.
Verification Checklist
| Verification Stage | Party to Confirm With | Items to Confirm | Actions if There Are Issues |
|---|---|---|---|
| When receiving accident notification | Shipper, Consignee, Warehouse, Delivery Company, Internal Staff | Accident discovery date/time, discovery location, cargo condition, photos, videos, receipts, POD | Fix the documents and records before attempting cause estimation. |
| When confirming the transport segment where it occurred | Shipping company, NVOCC, CFS, Warehouse, Delivery Company, Overseas Agents | B/L, House B/L, Master B/L, devanning records, inbound records, delivery records, seal numbers | If the segment is unknown, send preservation of rights notices to all related parties. |
| When confirming the cause of damage | Shipper, Surveyor, Warehouse, Insurance Company, Delivery Company | Exterior dents, wet marks, packaging condition, temperature logs, cargo-specific characteristics, pre-shipment condition | Do not decide the cause based on assumptions; confirm whether a survey is required. |
| When notifying related parties | Carrier, NVOCC, CFS, Warehouse, Delivery Company, Overseas Agents | Notification recipients, notification deadlines, expressions for preserving rights, request for record preservation, attached photos | Do not assign responsibility; state that cause and segment of occurrence are under investigation. |
| When contacting the insurance company | Cargo insurance company, Freight Forwarder liability insurance company, Insurance agency | Confirmed facts, unconfirmed matters, survey necessity, insurance coverage, subrogation potential | Even if the cause is unknown, provide an early initial report and confirm evidence preservation and survey instructions. |
| When explaining to the shipper | Shipper, Consignee, Sales representative, Accident handler | Facts known at present, unsettled issues, documents under confirmation, notification status | Do not conclude responsibility or insurance payment; explain the investigation procedures. |
| When organizing as cause unknown | Management, Insurance company, Lawyer if needed | Confirmed documents, unconfirmed documents, responses from related parties, damage amount, investigation costs, recoverability | Record the scope of confirmation and reasons for judgment. |
| When deciding on claims or subrogation | Insurance company, Shipper, Carrier, NVOCC, Lawyer | Accident segment, responsible party, evidence, liability limitations, exclusions, statute of limitations | If evidence is insufficient, consider options including insurance handling, settlement, or claim abandonment. |
Forwarder's Involvement Scope
| Stage | What Can Be Assisted | What Should Not Be Determined | Practical Points |
|---|---|---|---|
| Initial response to cause unknown accident | Collect photos, POD, receipts, devanning records, delivery records | Determining responsibility of shipping company, delivery company, or shipper before document review | Prioritize evidence preservation over cause estimation. |
| Shipper Explanation | Explain facts known so far, unconfirmed matters, scheduled confirmations, notification status | Stating "Insurance will definitely pay" or "Shipping company is responsible" | Separate explanation of cause unknown status and ongoing response. |
| Notifying related parties | Send rights preservation notices and requests for record preservation while cause remains unknown | Deciding not to notify until cause is known | Notifications are for securing investigation opportunities, not for assigning responsibility. |
| Insurance company response | Make initial accident report, confirm survey necessity, check subrogation potential | Deciding it's pointless to contact insurance company because the cause is unknown | Early notification can be effective even if cause is unknown. |
| Cause investigation | Organize documents by segment where the incident occurred, cause of damage, and liable party | Collect documents based on only one presumed cause | Keep multiple hypotheses open for investigation. |
| Final organization | Record confirmed documents, unconfirmed points, and related parties’ answers | Processing as cause unknown without any confirmation | Document the decision process that led to cause unknown. |
Common Practical Issues
| Case | Common Issues | Documents to Check | Practical Points to Note |
|---|---|---|---|
| Case where the cause of water damage could not be identified | It becomes difficult to differentiate between seawater damage, rainwater, condensation, water damage during storage after delivery, or moisture inside packaging. | Photos inside the container, photos of the floor surface, packaging materials, survey documents, storage conditions after delivery, POD | Even if the cause is unknown, notify the shipping company, delivery company, and insurance company. |
| Case where it is unclear if damage occurred during transport or after unpacking | No photos before opening, so it is impossible to determine whether the accident occurred during transport or during warehouse handling. | Photos before opening, video during opening, POD, warehouse work records, photos of outer packaging | Gradually keep photos before opening, during opening, and after opening. |
| Case where the location of quantity shortage could not be identified | Cannot determine whether the shortage occurred at export, due to CFS sorting errors, loss during transport, or movement after delivery. | Packing List, vanning records, CFS records, loading/unloading records, delivery slips, receipts | Trace the timing of quantity confirmation and the responsible manager in sequence. |
| Case where cause of temperature deviation was unknown | Disputes may arise over incorrect temperature settings, power connection failure, equipment malfunction, insufficient pre-cooling, or deficiencies on the shipper's side. | Temperature logs, set temperatures, pre-cooling records, reefer PTI, power connection records, work instructions | Check not only temperature logs but also instructions and work records. |
| Case where no remarks were on the receipt and the cause was unknown | Claims of undamaged handover, making later damage claims difficult. | POD, receipt, photos at delivery, photos at unpacking, inspection records, consignee communication records | Even without remarks, immediately notify and preserve evidence after damage discovery. |
| Case where the shipper discarded goods first | Impossible to conduct physical inspection, survey, residual value confirmation, or investigation into the damage cause. | Photos before disposal, disposal certificate, shipper instructions, insurance company contact, survey confirmation | Advise to consult insurance company and related parties before disposal. |
| Case where notification was sent only to one party and others were forgotten | Even if the accident section is unknown, notifying only the shipowner or only the delivery company eliminates other possible parties. | Notification records, B/L, delivery records, CFS records, warehouse records, responses from parties involved | When the section is unclear, notify all potentially related parties broadly. |
| Case where responsibility was admitted despite unknown cause | Initial admissions may be used disadvantageously later if packaging defects or post-delivery accidents emerge. | Initial emails, shipper responses, accident documents, survey documents, insurance company responses | Separate receipt confirmation and responsibility acceptance while the cause is unknown. |
Example 1: Case where the cause of water damage could not be identified
After delivery of imported FCL cargo, the shipper contacted us reporting "some cartons have water stains." There were no remarks on the receipt, and no abnormal appearance reports on the delivery day.
The freight forwarder immediately requested photo evidence from the shipper, and checked the container number, seal number, devanning records, delivery records, and container exterior photos.
The photos showed water stains on some cartons, but no clear water leakage traces were found on the container exterior walls or ceiling. Water on the floor was also limited, making immediate judgment difficult as to whether the damage was from seawater, condensation, or water during storage after delivery.
The freight forwarder notified the shipping company and delivery company to preserve rights, and also reported the accident promptly to the insurance company. After confirming whether a survey was needed, they explained to the shipper that "the cause and location of occurrence are under investigation, and the responsible party has not been determined at this time."
Subsequently, the survey also could not confirm a clear external water damage cause, and possibilities such as storage conditions and moisture inside packaging remained. Ultimately, there was insufficient evidence to clearly pursue carrier responsibility, and the matter was handled mainly through marine cargo insurance and internal records.
In this case, the failure was not that the cause remained unidentified until the end. The important point was that even when the cause was unknown, notification, evidence preservation, and initial reporting to the insurance company were conducted, leaving records that could be explained later.
Example 2: Case where it was unclear if damage occurred during transport or after unpacking
Upon unpacking imported cargo at the warehouse, damage was found on some inner boxes. However, there were no photos of the exterior before opening or videos during unpacking.
The shipper claimed the damage occurred during transport, but the warehouse responded that it "could also have happened during handling after unpacking." There were no remarks of damage on the receipt, and the delivery company stated that delivery was made without abnormalities.
In this case, although damage presence was confirmed, proving the damage occurred during a specific stage became difficult. Ideally, photos of the exterior, pallet condition, photos before and after opening, POD, and warehouse work records should have been retained, and rights preservation notices sent to both the delivery company and warehouse while the cause was still unknown.
Example 3: Case where the occurrence location of quantity shortage was unknown
For LCL cargo, after delivery, a shortage in carton quantity was discovered. The shipper suspected loss during transport, but it could not be determined whether the shortage occurred at export CFS loading, co-loading sorting, import CFS unloading, or domestic delivery.
The freight forwarder checked the Packing List, export CFS records, transshipment records for co-loads, import CFS unloading records, delivery company pick-up records, and consignee receipts.
Results showed that the quantity at import CFS unloading was likely complete, but quantity confirmation at delivery was insufficient. However, a definitive responsible party could not be identified.
In this case, it was important not simply to describe the shortage as “loss during transport” but to sequentially verify quantity records at each stage. In quantity shortages, it is necessary to trace who managed the cargo and how many units existed in chronological order.
Common Misunderstandings
| Common Misunderstandings | The Actual Approach | Practical Points to Note |
|---|---|---|
| It is acceptable to wait for notification until the cause is known | Even if the cause is unknown, early notification may be required to meet notification deadlines or preserve evidence. | Indicate that the cause and location of occurrence are under investigation when issuing a rights preservation notice. |
| No insurance payout if the cause is unknown | Even if the cause is unknown, the insurer will make a decision based on policy terms, accident circumstances, and evidence. | Do not conclusively determine the cause; separate confirmed facts from unconfirmed matters in the initial report. |
| No remarks on the receipt prove there was no problem | While the absence of remarks is important, it does not necessarily disprove damage discovered later. | Check POD, unpacking photos, inspection records, and discovery timing. |
| Nothing can be done if the cause is unknown | Even if the cause is unknown, it is possible to preserve evidence, notify involved parties, arrange a survey, and notify the insurer. | Before determining the cause, create a state where investigation can proceed. |
| It’s fine to speculate and communicate the cause quickly to the shipper | Speculating on the cause can cause difficulties explaining findings if another cause later emerges. | Clearly categorize and explain terms like "under investigation," "possible," and "undecided." |
| Notify only the party most likely responsible | If the location of occurrence is unclear, notifying only one party can delay notices to other potential claim targets. | Send rights preservation notifications broadly to all parties who may be involved. |
| The freight forwarder must be responsible if involved, even if the cause is unknown | Forwarder responsibility depends on contractual position, scope of control, negligence, and terms. | Confirm whether acting as agent or NVOCC and whether the forwarder undertook handling operations. |
| If the cause ultimately remains unknown, record keeping is unnecessary | Especially when processing as unknown cause, it is important to record what was confirmed and what was not. | Keep internal records of the scope of verification, responses from involved parties, and rationale for decisions. |
Practical Points to Note
When the cause of an accident is unknown, the freight forwarder should not simply leave it as "unknown" but categorize "what is unknown."
Whether the unknown relates to the location of occurrence, damage cause, or responsible party will affect which documents need to be checked and to whom notification should be sent.
Even before the cause is determined, it may be necessary to proceed with notification deadlines, evidence preservation, arranging surveys, and initial accident notification to the insurer.
In dealing with unknown causes, it is important to avoid definitive statements, collect records, notify relevant parties, and document the scope of the investigation.
Even if ultimately processed as an unknown cause, being able to explain the process that led to this conclusion is crucial practical work for forwarders.
Summary
When the cause of an accident is unknown, the freight forwarder should organize whether it falls under unknown location of occurrence, unknown damage cause, or unknown responsible party rather than speculating the cause.
At the unknown cause stage, secure and preserve documents such as photos, POD, receipts, devanning records, delivery records, B/L, House B/L, and Master B/L, and consider sending rights preservation notices to involved parties and initial notifications to the insurer.
Being unable to identify the cause is not a failure in itself. What is important is not leaving the unknown unaddressed, but recording what was checked, who was notified, and how far the investigation proceeded, enabling explanations to shippers, insurers, and carriers.
