Import Container Seal Number Discrepancy — Pre-Opening Checks and Initial Response
Interlink編集部Seal Number Mismatch and Unopened Condition Confirmation
Seal number mismatch and unopened condition confirmation refer to the practical process of verifying that the seal number recorded on documents such as the B/L, Arrival Notice, D/O, and delivery record matches the actual seal number on the imported container upon arrival.
In freight forwarder operations, a difference in seal numbers does not immediately lead to a conclusion of theft, pilferage, or carrier liability. It is necessary to sequentially check multiple possibilities including customs inspection, resealing at the load port, transshipment, document correction omissions, or recording errors.
However, seal number mismatches, seal damage, or absence of seals serve as initial indicators for issues such as quantity shortages, cargo pilferage, wet damage, damage, cargo shifting, or misdelivery. If cargo abnormalities are discovered after opening, whether or not the seal condition before opening was recorded will affect B/L claims, NVOCC notifications, insurance handling, and claims for indemnity.

Situations Where This Becomes a Practical Issue
Seal number mismatches become an issue when the actual seal number on the container at arrival does not match the documents, when the seal is damaged, missing, or replaced with a different seal number during resealing.
Also, if quantity shortages, cargo pilferage, wet damage, damage, or cargo shifting are found after opening, records of seal number verification become important evidence.
A seal number mismatch itself does not necessarily indicate damage. However, it serves as an entry point to confirm at what stage, by whom, and for what reason the container was opened or resealed. Therefore, at the site, before rushing to open the container, document cross-checks, photographic records, and consultation with involved parties are needed.
Classification of Causes for Seal Number Mismatch
| Situation | Items to Confirm | Notification Recipients | Practical Notes |
|---|---|---|---|
| Resealing After Customs Inspection | Check for customs inspection presence, opening location, resealing number, inspection records, and EIR notation. | Customs broker, customs officials, CY, CFS, NVOCC, shipping line agent | Even legitimate resealing without records may be difficult to explain later. |
| Resealing at Load Port or Transshipment Point | Check resealing records at load port warehouses, overseas agents, transshipment locations, and during transshipment. | Overseas agents, NVOCC, shipping line, load port forwarder | Resealing records at the local site may not be reflected in import-side documents. |
| Document Mistakes or Correction Omissions | Check differences in numbers between B/L, Arrival Notice, D/O, EIR, and delivery tickets. | NVOCC, shipping line agent, customs broker, warehouse | Confirm which document holds the latest information and keep correction records. |
| Record Differences During Port or CY Operations | Confirm CY gate out records, EIR, delivery tickets, gate records, and seal verification records. | CY, CFS, shipping line agent, delivery company, NVOCC | Cross-check whether port operation records and documentation information match. |
| Seal Damage or No Seal | Confirm damage condition, seal remnants, door surroundings, signs of pilferage, and cargo quantity. | NVOCC, shipping line, CY, CFS, warehouse, shipper, insurance company | Take photos before opening, and consider supervision or surveys if necessary. |
| Suspected Theft or Pilferage | Check quantity shortage, signs of external opening, cargo shifting, case marks, CCTV, and delivery and pickup records. | Shipper, warehouse, delivery company, NVOCC, shipping line, insurance company, relevant authorities as needed | Do not conclude theft based solely on seal number mismatch—verify with quantity records and cargo condition. |
Documents to Check First
When a seal number mismatch is identified, first check the B/L, Arrival Notice, D/O, EIR, delivery ticket, devanning instructions, warehouse delivery records, and container pickup records.
If the seal numbers differ across documents, confirm which document contains the most recent information and at what stage the number changed.
For example, if the seal number on the B/L differs from the seal number on the Arrival Notice, it needs to be checked whether a correction was made at the loading port, whether the latest information was reflected when creating the Arrival Notice, or if it was simply a transcription error. If a different number is recorded on the D/O or EIR, matching it against the actual seal on the container at the time of CY pickup becomes crucial.
Points for Physical Inspection
For a physical container, confirm the container number, seal number, type of seal, presence or absence of seal damage, damage around the doors, and any signs of resealing.
Photographs should include the entire container, container number, seal number, close-ups of the seal, the area around the doors, and any abnormal points. A photo of just the seal number may not identify which container it belongs to, so it is important to keep a combination of full container photos and close-up shots.
In addition to close-up photos of the seal number, photos that clearly show both the container number and seal together, full door photos, and photos that reveal whether there is damage around the seal are helpful for future explanations.
Actions to Take Before Opening
If a mismatch in seal numbers, seal damage, or absence of a seal is confirmed, do not open the container immediately. First, document the unopened condition.
Then, contact the shipper, warehouse, CFS, delivery company, NVOCC, shipping agent, and others to confirm whether an opening witness, photo documentation, survey arrangement, or preservation of records is necessary.
Especially when a shortage or pilferage is suspected, the condition of the seal before opening and the stowage condition immediately after opening are critical. Proceeding without permission may cause difficulties later in explaining when, who, and under what conditions the container was opened, so caution is required.
Relation to Customs Inspection and Resealing
Even if the seal number has changed, there may have been a legitimate opening and resealing carried out by customs inspections or involved parties.
Therefore, freight forwarders should confirm whether a customs inspection took place, where the container was opened, the new seal number applied during resealing, records by involved parties, and any corrections in the system. Even legitimate resealing can become difficult to explain during claim handling if records are not maintained.
Even when resealing records can be confirmed, if there is cargo shortage or damage, it is necessary to verify the cargo condition before and after resealing, handling during inspection, and records of attendance at the opening. The fact of resealing alone does not resolve all issues.
Relation to Cargo Shortage
Seal number discrepancies can be related to shortage claims. If cargo is found to be short after opening, mismatched or damaged seals become points to check during transport or at inspection and resealing.
However, seal discrepancies alone do not determine the cause of shortages. It is necessary to cross-check B/L quantity, packing lists, devanning records, warehouse receipt, photos, and inspection records together.
Organizing whether the external quantity matches, if internal units are short, shortages at the pallet level, or if stowage was disturbed before opening helps clarify the relationship between seal irregularities and quantity discrepancies.
Relation to Wet Damage and Physical Damage
If the seal number differs or the seal is damaged, carefully inspect the container’s interior condition at the time of opening. Check for wet cargo, rust, mold, cargo shift, outer packaging damage, strange odors, and water stains on the floor.
If abnormalities are found in the cargo, organize photos of the container exterior, seals, right after opening, devanning records, and photos of the cargo in chronological order.
Even if the spatial relation between seal anomalies and cargo damage is unclear, keeping records before and immediately after opening forms useful materials for later confirmation with insurers, NVOCC, carriers, and warehouses.
Relation to B/L Claim Letters
If a seal number discrepancy is found along with cargo damage or shortage, consider issuing a B/L claim letter or damage notification to the maritime carrier.
When notifying, organize details such as the B/L number, container number, seal numbers on documents and on the actual cargo, the date of anomaly discovery, opening condition, damage details, photos, and devanning records.
At an early stage where the cause is not established, notify in a way that does not assign blame, for example: “The seal number did not match the documentation upon arrival, and confirmation is ongoing during opening,” or “Cargo abnormalities were confirmed after opening, so this is to preserve rights.”
Relation to NVOCC Notifications
For House B/L cases, notifying the NVOCC of claims is also important. When the NVOCC is involved as the carrier on the House B/L, promptly notify them of discrepancies in seal numbers, opening confirmation, and cargo abnormalities.
Since the NVOCC may need to check with the actual carrier, prepare to share photos, seal numbers, devanning records, EIR, and delivery records early on.
Especially when the NVOCC will make subsequent notifications or claims against the actual carrier, initial records of seal discrepancies, photos before opening, EIR, and devanning records are critical. Notifications from the shipper to the NVOCC and from the NVOCC to the actual carrier should be confirmed separately.
Differentiation from Marine Cargo Insurance
Seal discrepancies do not automatically lead to a marine cargo insurance claim. First, confirm whether there is actual damage to the cargo, a shortage, and when the damage was discovered.
Even when proceeding with insurance claims, confirmation of the seal number, photos before and during opening, devanning records, cargo photos, and survey reports become essential documents. Freight forwarders need to manage accident notifications to the insurer separately from notifications to the carrier or NVOCC named on the B/L.
When shortages, suspected pilferage, wet damage, physical damage, or high-value cargo are involved, an early incident report should be made to the insurer or insurance agent to confirm the necessity of a survey and how to preserve the cargo.
Confirmation Checklist
| Verification Situation | Contact Party | Items to Check | Actions if Issues Found |
|---|---|---|---|
| When a seal number discrepancy is discovered | Warehouse, CFS, delivery company, CY, delivery destination | Date and time discovered, location discovered, container number, actual seal number, seal condition | Take photos before opening and notify relevant parties. |
| When verifying documents | Freight forwarder, NVOCC, shipping line agent, customs broker | Seal numbers on B/L, Arrival Notice, D/O, EIR, loading slip, devanning instructions | Confirm which document has the latest information and at what stage the number changed. |
| When inspecting the actual cargo | Warehouse, CFS, delivery company, shipper, surveyor as needed | Seal type, any damage, around the doors, signs of resealing, container external abnormalities | Record a combination of overall photos and close-up photos. |
| When deciding before opening | Shipper, warehouse, NVOCC, shipping line agent, insurance company | Need for supervision, need for survey, permission to open, photo coverage, method for quantity confirmation | If there is suspected shortage or pilferage, verify before operations begin. |
| When checking the possibility of resealing | Customs broker, customs officials, CY, CFS, NVOCC, overseas agents | Customs inspection, reseal number, inspection records, correction records, transshipment records | Obtain records even if resealing is legitimate. |
| At devanning | Warehouse, CFS, devanning contractor, shipper, surveyor | Loading condition immediately after opening, cargo arrangement, shift, moisture, damage, quantity, packaging condition | Check the relationship between seal irregularities and cargo irregularities. |
| When judging B/L or NVOCC notifications | NVOCC, shipping company, B/L issuer, overseas agents | B/L number, container number, seal number on documents, actual seal number, notification recipients, notification deadlines | Consider rights preservation notification even if the cause is not yet confirmed. |
| When contacting the insurance company | Cargo insurance company, insurance agent | Cargo damage, quantity shortage, pre-opening photos, seal photos, devanning records, need for survey | Confirm with the insurance company before altering the cargo condition. |
Freight Forwarder's Scope of Involvement
| Situation | Support That Can Be Provided | Things Not to Conclude | Practical Points |
|---|---|---|---|
| Initial Checks | Comparing seal numbers on documents with the actual seal numbers | Concluding theft or pilferage based only on seal number discrepancy | Also check customs inspections, resealing, and document errors. |
| Pre-opening Measures | Recording pre-opening photos, seal condition, around the doors, and container number | Deciding that post-opening checks alone are sufficient | The pre-opening condition cannot be reproduced later. |
| Contacting Relevant Parties | Confirming with the shipper, warehouse, NVOCC, shipping line agent, insurance company | Assuming that contacting only one party suffices for all relevant parties | Separate notifications for contractual parties and site parties. |
| Quantity Confirmation | Verifying against B/L quantity, packing list, devanning records, warehousing records, inspection records | Concluding the cause of quantity shortage solely based on seal number discrepancy | Confirm quantity shortages in chronological order. |
| Insurance Handling | Reporting incidents and checking survey requirements with the insurance company if cargo damage or quantity shortage exists | Determining insurance payment eligibility solely from seal number differences | Insurance decisions are based on cargo damage and policy terms. |
| Subsequent Notifications | Organizing rights preservation notifications to the carrier listed on B/L, NVOCC, and actual carrier | Deciding not to notify until the cause is confirmed | Notifications may be required even if the cause is not yet confirmed. |
Common Practical Issues
| Case | Common Issues | Documents to Check | Practical Notes |
|---|---|---|---|
| Case where the physical seal number does not match the B/L | It is necessary to differentiate between document errors, resealing at the loading port, customs inspection, and intermediate opening. | B/L, Arrival Notice, D/O, EIR, photos of the physical seal | Confirm which document contains the most up-to-date information. |
| Case where the seal is damaged | Multiple possibilities such as seal removal suspicion, damage during handling, or missed resealing exist. | Seal photos, photos around the door, EIR, delivery records, quantity confirmation records | Contact relevant parties before opening and preserve the records. |
| Case where no seal is attached | Issues arise from intermediate opening, missed resealing after inspection, seal detachment during transportation, or inadequate on-site records. | Container photos, door photos, EIR, CY dispatch records, inspection records | Carefully check the condition before opening and the cargo quantity. |
| Case of resealing after customs inspection | Even if resealing itself is legitimate, explanation becomes difficult without proper records. | Customs inspection records, reseal numbers, EIR, customs broker records | Obtain the reseal number and inspection records. |
| Case where quantity shortage was found after opening | The causal relationship between seal irregularities and quantity shortage becomes a key issue. | B/L, Packing List, devanning records, warehouse entry records, photos before opening, inspection records | Separate the confirmation of outer packaging quantity, inner packaging quantity, and product quantity. |
| Case where wet damage or breakage was found after opening | It is necessary to distinguish between seal irregularities, container external damage, external forces during transportation, and storage after devanning. | Photos before opening, photos immediately after opening, photos inside the container, cargo photos, Survey Report | Keep continuous records linking conditions before and immediately after opening. |
| Case where the seal number discrepancy was overlooked and devanning proceeded as usual | If quantity shortage or damage later becomes evident, the pre-opening condition cannot be explained. | Staff memos, devanning records, cargo photos, warehouse entry records | When a seal difference is noticed, immediately take photos and keep records. |
| Case where seal numbers differ across multiple documents | Confusion arises as to which document among the B/L, Arrival Notice, D/O, and EIR should be the reference. | B/L, Arrival Notice, D/O, EIR, correction records, overseas agent responses | Separate and organize the timing of document preparation and physical confirmation. |
Example 1: Case of resealing after customs inspection
When the imported FCL cargo arrived at the warehouse, the physical seal number did not match the number indicated on the D/O. The warehouse staff took photos of the container number, the physical seal number, seal condition, and around the container door before opening, and contacted the freight forwarder.
The freight forwarder cross-checked the B/L, Arrival Notice, D/O, and EIR, and confirmed with the customs broker and NVOCC. As a result, it was found that a customs inspection had been carried out upon import, and the container was resealed with a different seal number after the inspection.
In this case, the seal number discrepancy was confirmed to be due to legitimate resealing after inspection, not theft or seal removal.
However, if there is no record of the resealing, explaining any subsequent quantity shortages or damage may be difficult. Even when resealing is legitimate, obtaining and preserving records is important.
Example 2: Case where quantity shortage was found after seal damage
Upon arrival at the warehouse, part of the container seal was damaged, and the site notified the freight forwarder. Before opening, photos were taken of the seal damage area, container number, around the door, and the entire container.
After notifying relevant parties, the container was opened, and a shortage of some cartons was confirmed during devanning.
In this case, to verify the relationship between the seal damage and quantity shortage, it is necessary to cross-check the B/L quantity, Packing List, devanning records, warehouse entry records, photos taken immediately after opening, and CFS or CY dispatch records.
Seal damage alone does not allow a definite conclusion of theft, but having pre-opening records provides useful documentation for subsequent B/L claims, NVOCC notifications, and explanations to the insurance company.
Example 3: Case of seal number differences due to document errors
The physical seal number of the imported container differed from the number on the Arrival Notice, but matched the EIR.
The freight forwarder confirmed with the NVOCC and discovered that it was a transcription error when creating the Arrival Notice, and the B/L correction information was not reflected in some documents.
In this case, the seal number difference was not due to actual opening or resealing, but a document error.
However, if the document error is not verified and operations proceed as usual, it becomes difficult to explain seal management if cargo damage or quantity shortage is discovered later. It is important to verify which documents are correct and to keep records of corrections, even in case of document errors.
Common Misunderstandings
| Common Misunderstandings | Actual Considerations | Practical Points to Note |
|---|---|---|
| Mismatched seal numbers definitely indicate theft | There are multiple possibilities such as customs inspection, resealing, document errors, transshipment, or recording omissions. | Do not jump to conclusions about the cause; cross-check documents and the actual cargo. |
| There is no problem if the container is resealed | Even if the resealing itself is legitimate, issues may arise relating to the condition of the cargo before and after resealing or related records. | Verify inspection records, reseal numbers, and attendance records. |
| Even if the seal number on the documents is incorrect, there is no problem if the quantities match | Even if quantities match, concealed damage or issues affecting insurance or claims could arise later involving seal management. | Record reasons for the seal number discrepancy. |
| Taking photos after opening is sufficient | After opening, it is impossible to reproduce the seal condition before opening, door condition, or abnormal points. | Keep separate photos taken before opening, immediately after opening, and during devanning. |
| Seal damage always means pilferage | Damage could occur during handling, due to aging, inspections, or missed resealing. | Check alongside quantity shortages, cargo arrangement, and signs of exterior opening. |
| Only the seal number on the B/L needs to be confirmed | Seal numbers may differ between documents such as Arrival Notice, D/O, EIR, and gate tickets. | Cross-check multiple documents. |
| Notifying the insurance company makes B/L carrier notification unnecessary | Accident notification to the insurer and notification to the carrier or NVOCC on the B/L are separate practical procedures. | Manage insurance notifications and carrier notifications in parallel. |
| No need to document just a seal number discrepancy | Even if there is no cargo damage at that time, shortages or hidden damage may be discovered later. | At minimum, keep photos of the cargo, document cross-checks, and confirmation outcomes. |
Practical Points to Note
Seal number discrepancies are an important entry point in international transport claims. However, a difference in seal numbers alone cannot definitively determine cargo damage causes or responsibility scope.
Freight forwarders should organize the status before opening, seal numbers on documents, actual seal numbers, resealing records, presence or absence of customs inspection, devanning records, and cargo photos in chronological order. They should also separate confirmed facts from matters under investigation with carriers shown on the B/L, NVOCCs, shipping line agents, shippers, and warehouses.
Particularly when a seal number discrepancy, seal damage, or missing seal is confirmed, photos before opening must always be retained. Record container numbers, seal numbers, door area conditions, seal status, and exterior abnormalities, and consider attendance, survey, and notifying relevant parties as needed.
When cargo damage or quantity shortages are confirmed, it is important to separate and properly manage accident notifications to the insurance company and rights preservation notifications to the carrier or NVOCC on the B/L.
Summary
Seal number discrepancies and opening inspections are practical procedures at container arrival where the seal numbers recorded on the B/L, Arrival Notice, D/O, and gate records do not match the physical container’s seal numbers, prompting confirmation of the pre-opening condition.
A seal number difference does not immediately confirm theft, pilferage, or carrier liability. Customs inspections, resealing, transshipment, document errors, and recording omissions should be systematically checked.
In practice, B/L, Arrival Notice, D/O, EIR, gate tickets, actual seal numbers, container numbers, photos before opening, loading condition immediately after opening, devanning records, and cargo photos are all organized chronologically.
A seal number discrepancy itself is not a final judgment, but rather an entry to opening inspection, quantity confirmation, cargo damage verification, B/L notifications, NVOCC notifications, and marine cargo insurance responses. The key is to avoid premature conclusions, preserve records, and perform necessary verifications with stakeholders.
