Shortage of Quantity During Maritime Transport
Interlink編集部What Quantity Shortage During Marine Transportation Means
Quantity shortage during marine transportation refers to a discrepancy between the quantities stated on documentation such as the B/L, Packing List, and Invoice, and the quantities actually confirmed after import.
In freight forwarder practice, even if a quantity shortage is found, it cannot be immediately concluded that it resulted from loss during marine transportation or the carrier's liability. It is necessary to sequentially check for shortages at loading at origin, documentation errors, shortages inside the container, missed checks at devanning, record discrepancies at warehouse receipt, and quantity differences after domestic delivery.
It is especially important to distinguish whether the shortage is in the number of outer packages or if the outer packages are complete but the content quantity inside is lacking. The quantities on the B/L, Packing List, Invoice, devanning quantity, warehouse receipt quantity, and inspection quantity may each have different meanings.

Situations Where This Becomes a Practical Problem
Quantity shortages during marine transportation become problematic when the number of outer packages is short at devanning, the package count on the B/L does not match the actual warehouse receipt count, the number of pallets matches but case count is short, or inner content shortage is discovered after unpacking inspection.
Also, when there are differing seal numbers upon container arrival, damaged seals, abnormalities on container exterior, or when cargo shifting or obvious empty spaces are noticed during devanning, it is necessary to verify the connection with any quantity shortage.
Quantity shortage is not simply a matter of "goods disappearing during marine transport." It is important to distinguish and verify what quantity is stated on the B/L, what is on the Packing List, what was actually counted on site, and at what point the shortage was identified.
Difference Between Outer Package Shortage and Inner Quantity Shortage
| Category | Verification Documents | Notification/Confirmation Parties | Possible Responsible Parties / Notes |
|---|---|---|---|
| Outer Package Shortage | B/L, D/O, Arrival Notice, Packing List, Devanning Records, Warehouse Receipt Records, POD | Marine carrier, NVOCC, CFS, warehouse, delivery company, shipper | It is necessary to confirm at which stage the shortage occurred: international transport, CFS operations, devanning, warehouse receipt, or domestic delivery. |
| Inner Quantity Shortage | Packing List, Invoice, Inspection Records, Unpacking Records, Shipping Details, Manufacturer Shipping Records | Shipper, exporter, manufacturer, packing company, and insurance company as needed | If the outer packages are complete, the primary focus is on verifying packing, inspection, and shipped quantities at the origin. |
| Pallet Count Matches but Case Count Is Short | Packing List, Pallet Details, Devanning Records, Warehouse Receipt Records, Case Mark Photos | Warehouse, CFS, NVOCC, shipper, exporter | Avoid confusion between pallet units and case units. |
| Case Count Matches but Product Quantity Is Short | Invoice, Packing List, Inspection Records, Unpacking Photos, Shipping Inspection Records | Shipper, exporter, manufacturer, consignee | If the B/L quantity is stated by outer packaging units, the carrier may not have confirmed the number of individual items inside. |
| Discrepancies in Documented Quantities | B/L, Invoice, Packing List, D/O, Arrival Notice, Correction Records | Exporter, NVOCC, shipping line agent, customs broker, shipper | Possibility that the shortage is not actual but a result of errors or omissions in document preparation or corrections should also be checked. |
Documents to Check First
When a quantity shortage is confirmed, start by checking the B/L, Arrival Notice, D/O, Invoice, Packing List, container number, seal number, devanning records, warehouse receipt records, and inspection records.
It is particularly important to separately organize the quantities on the B/L, Packing List, quantities actually devanned, quantities recorded upon warehouse receipt, and quantities confirmed at the delivery destination.
Without verifying what each document is actually counting, outer package shortages and inner quantity shortages can easily be confused. For example, if the B/L states 20 packages, the Packing List states 20 cartons, and the Invoice states 200 pieces, these units are not equivalent.
Relationship with B/L Quantity
The quantity stated on the B/L is important information for confirming marine transport. However, the B/L quantity does not necessarily guarantee the detailed quantity of contents.
It is necessary to confirm whether the quantity on the B/L indicates the number of cartons, cases, pallets, or containers. Confusing the number of outer packages with inner quantity can lead to incorrect judgments about shortages.
Also, for FCL cargo, situations can arise where the shipper declares the loading quantity, such as with "Shipper's Load and Count," and the carrier has not directly verified the container contents. Even in such cases, organize the B/L quantity, seal condition, devanning records, and photos taken during opening to identify where the quantity differences may have occurred.
Difference Between Outer Package Quantity and Inner Quantity
When there is a shortage, first distinguish whether the shortage is in the outer package quantity or the inner quantity.
If there is a shortage in the outer package quantity, the focus will be on confirming the B/L, D/O, devanning records, warehouse receipt records, seal numbers, and container condition. On the other hand, if the outer package quantity is correct but the inner quantity is short, the packing, shipment, inspection on the loading side, and handling after opening will be relevant for investigation.
Shortages in the outer package quantity are often treated as issues occurring during the transport segment or within warehouse and delivery processes, whereas inner quantity shortages tend to be regarded as issues related to packing, inspection, shipment quantity, and product details at the shipment origin. However, if outer packages have been opened or there are seal abnormalities, both possibilities should be verified.
Checks During Devanning
At devanning, confirm the loading condition immediately after opening the container, the cargo arrangement, number of pallets, cases, presence of cargo collapse, and any empty spaces.
If a quantity shortage is suspected, it is important to document photographs inside the container before removing cargo, records during devanning, extracted quantities, and the quantity received into the warehouse. Even if a shortage is discovered after devanning, without records of the condition at the time of opening, verification becomes difficult.
During quantity confirmation in devanning, record the number of outer packages, pallets, cases, warehouse receipt quantity, and inspection quantity separately. It is important to be able to reconcile warehouse work records and shipper inspection records at a later time.
Relationship with Seal Numbers
If a shortage occurs, checking seal numbers is important. Confirm whether the seal numbers listed on the B/L, Arrival Notice, D/O, or delivery records match the physical seal numbers.
If discrepancies such as different seal numbers, seal damage, resealing, or absence of seals are found, check the pre-opening photos, inspection at opening, customs inspection presence, and resealing records. However, seal abnormalities alone do not conclusively establish causes of quantity shortages.
Conversely, even if seal numbers match, quantity shortages may still occur. Issues such as insufficient loading at origin, discrepancies in the packing list, shortages within outer packages, or counting errors during inspection can occur despite matching seal numbers.
Items to Document with Photographs
When a quantity shortage is suspected, photograph the container’s exterior, container number, seal number, interior immediately after opening, the entire cargo, labels, pallets, case numbers, and remaining cargo condition after devanning.
Since missing cargo cannot be directly photographed, it is important to capture the actual condition of existing cargo, loading patterns inside the container, label information, and the sequence of quantity confirmation.
Particularly, photographs of the container interior immediately after opening, photos of each pallet, case marks, labels, and quantity check photos at warehouse receipt may be used later in B/L claim letters, NVOCC notifications, insurance explanations, or recourse responses.
Relation to B/L Claim Letters
If a quantity shortage could have occurred during international transport, considering sending a B/L claim letter or damage notification to the maritime carrier is advisable.
When issuing a notice, organize the B/L number, vessel name, voyage number, container number, seal number, quantity on B/L, actual checked quantity, shortage quantity, date abnormality was found, devanning location, photos, and devanning records.
Even if the cause or liability of the shortage is not yet determined, to preserve rights, the fact that a quantity discrepancy has been confirmed may be notified first. The notification should clearly state that the cause, responsibility, and damage amount are under investigation.
Relation to Notifications to NVOCC
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, notify them promptly when quantity shortages are discovered, providing the B/L quantity, devanning quantity, warehouse receipt quantity, photos, and seal numbers.
Since the NVOCC may need to verify with the actual carrier, organize and share the House B/L, Master B/L, D/O, devanning records, and warehouse receipt records.
If there are discrepancies between quantities on the House B/L and Master B/L, or issues involve co-load cargo, LCL cargo, or CFS cargo, separate and clarify where quantities have been confirmed—whether by NVOCC, CFS, or actual carrier.
Separating from Marine Cargo Insurance
Quantity shortages occurring during maritime transport may be considered under marine cargo insurance. However, in freight forwarder practice, accident notifications to the insurer need to be handled separately from damage notifications to carriers or NVOCCs appearing on the B/L.
Even when proceeding with insurance claims, documents such as the B/L, Packing List, devanning records, warehouse receipt records, photos, Survey Report, and evidence supporting shortage quantities are important. These are used not only for insurance claims but also for notifications to carriers and liability allocation.
Notifying the insurance company does not eliminate the need to notify maritime carriers or NVOCCs. In cases where the insurer pursues subrogation later, the initial notifications, quantity records, photographs, and chronological documents remain crucial.
Checklist for Confirmation
| Situation to Check | Party to Check With | Points to Check | How to Respond if There Is a Problem |
|---|---|---|---|
| When Discovering Quantity Shortage | Shipper, Consignee, Warehouse, CFS, Delivery Company | Date and time of discovery, location of discovery, details of shortage, whether exterior packaging quantity shortage or inner quantity shortage, photos | Confirm the unit of quantity and preserve records without immediately assigning responsibility. |
| When Checking B/L Quantities | Freight forwarder, NVOCC, Shipping Line, Overseas Agent | B/L number, quantity units, packages, cartons, pallets, container, presence of Shipper's Load and Count notation | Confirm whether the B/L quantity guarantees exact counts including inner units. |
| When Checking Packing List / Invoice | Shipper, Exporter, Manufacturer, Freight forwarder | Exterior packaging quantities, product quantities, item numbers, lot numbers, case marks, shipment details | Organize exterior packaging quantities and product quantities separately. |
| When Checking Quantities at Unstuffing | Warehouse, CFS, Unstuffing Contractor, Shipper | Arrangement immediately after opening, number of pallets, number of cases, quantity removed, work records | Keep photos immediately after opening and unstuffing records. |
| When Checking Warehouse Receipt Quantities | Warehouse, Shipper, Delivery Company | Warehouse receipt records, delivery receipts, POD, inspection records, storage location, photos at receipt | Check if there is a discrepancy between unstuffing quantities and warehouse receipt quantities. |
| When Checking Seal Numbers | Warehouse, CFS, NVOCC, Shipping Line, Customs Broker | B/L, Arrival Notice, D/O, EIR, physical seal, resealing records | Avoid concluding quantity shortage causes solely based on seal anomalies. |
| When Considering B/L or NVOCC Notifications | Ocean Carrier, NVOCC, B/L Issuer, Shipping Line Agent | Notification recipients, notification deadlines, shortage quantities, B/L quantities, actual confirmed quantities, photos, unstuffing records | Consider rights protection notifications even if the cause is not yet determined. |
| When Contacting the Insurance Company | Marine cargo insurance company, Insurance Agent | Insurance contract, shortage quantities, estimated damage amount, quantity evidence documents, necessity of survey | Manage insurance notification separately from carrier notification. |
Scope of Freight Forwarder Involvement
| Scenario | What Forwarders Can Support | What Should Not Be Concluded | Practical Points |
|---|---|---|---|
| Initial Response to Quantity Shortage | Collect B/L, Packing List, Invoice, unstuffing records, warehouse receipt records | Immediately concluding the quantity shortage is due to loss during ocean carriage | First confirm the unit of quantity and timing of discovery. |
| Confirming Exterior Packaging Quantity Shortage | Reconcile exterior packaging quantities, number of pallets, number of cases, unstuffing quantities, warehouse receipt quantities | Always attributing exterior packaging quantity shortage to carrier liability | Check each stage: loading point, CFS, unstuffing, warehouse, and delivery. |
| Confirming Inner Quantity Shortage | Reconcile Packing List, Invoice, inspection records, shipment records | Explain that B/L quantities guarantee inner quantities | Separate exterior packaging units and product units. |
| Responding to Seal Anomalies | Check seal numbers, resealing records, photos before opening | Conclude theft or pilferage based solely on seal number discrepancies | Also verify customs inspections, resealing, and document errors. |
| B/L and NVOCC Notifications | Consider rights preservation notifications to ocean carrier, NVOCC, shipping line agent | Decide that insurance notification alone makes carrier notification unnecessary | Manage insurance claims and carrier notifications separately. |
| Explaining to Cargo Owners | Explain confirmed quantities, shortage quantities, unconfirmed points, and future confirmation plans | Prematurely conclude causes or liable parties before document review | Organize and explain quantity discrepancies by unit and timeline. |
Cases Commonly Causing Problems in Practice
| Case | Common Issues | Documents to Check | Practical Notes |
|---|---|---|---|
| Cases where the number of cases on the B/L does not match the number of cases received into storage | The key issue is identifying where the shortage occurred—during sea transport, CFS operations, devanning, or warehouse receipt. | B/L, D/O, devanning records, warehouse receiving records, POD, photos | Confirm the timing when the shortage in outer packaging quantity was discovered. |
| Cases where the number of pallets matches but the number of cartons is short | There can be confusion between pallet units and carton units, leading to misinterpretation of quantity discrepancies. | Packing List, pallet details, devanning records, warehouse receiving records, photos of carton marks | Check pallet count, carton count, and inner quantity separately. |
| Cases with correct outer packaging quantity but shortage in the number of items | The issue tends to be on the loading side with packing, inspection, or shipment quantity, rather than loss during transport. | Invoice, Packing List, photos of unpacking, inspection records, shipment details | Do not confuse the quantity of outer packaging on the B/L with the actual number of goods inside. |
| Cases where seal number discrepancies and quantity shortages are found simultaneously | It is necessary to differentiate between theft, customs inspection, resealing, document errors, and loading shortages. | B/L, Arrival Notice, D/O, EIR, photos of seals, resealing records, devanning records | Do not jump to conclusions based solely on seal irregularities; cross-check with quantity records. |
| Cases where shortages are discovered during delivery destination inspection rather than after devanning | The issue is determining at which stage—devanning, receiving, domestic transport, or post-delivery inspection—the discrepancy arose. | Devanning records, receiving records, POD, receipt acknowledgments, photos taken at delivery, inspection records | Organize the discovery point and notification point chronologically. |
| Cases where quantity shortages occurred in LCL cargo | It is necessary to check CFS sorting, co-load, mixed cargo, and handling-out records. | House B/L, Master B/L, CFS records, handling-out records, warehouse receiving records, carton marks | Check records from NVOCC, CFS, and warehouse separately. |
| Cases where shortages are claimed in FCL under "Shipper's Load and Count" | The premise that the carrier has not checked quantities inside the container becomes an issue. | B/L, Packing List, seal numbers, photos before opening, devanning records, loading records at origin | Verify both the loading records at origin and the receiving-side opening records. |
| Cases where notification was given only to the insurer and delayed notice to the carrier | Later, the carrier or NVOCC may claim a delay in notification. | Insurance notification, B/L claim letter, NVOCC notification, notification dates, quantity records | Manage insurance notifications and carrier notifications simultaneously. |
Example 1: Case of Shortage in Outer Packaging Quantity
In an import FCL shipment, the B/L and Packing List indicated 100 cartons, but after devanning at the warehouse, the received quantity was 98 cartons.
The first point to confirm in this case is whether the quantity of 100 cartons is treated consistently as the same unit across the B/L, Packing List, D/O, and warehouse receipt records.
The freight forwarder checked photos inside the container immediately after opening, quantity records during devanning, warehouse receiving records, seal numbers, EIR, and POD. Simultaneously, they requested confirmation of stuffing and shipment records at the place of origin from the NVOCC and overseas agents.
For quantity shortages, causes may include not only loss during sea transport but also shortages during stuffing at origin, discrepancies in document records, or counting errors upon warehouse receipt. In the case of outer packaging shortages, it is important to organize the B/L quantity, point of opening, devanning quantity, and warehouse receipt quantity in a timeline.
Example 2: Case Where Outer Packaging Quantity Matches but Inner Quantity Is Short
In an import shipment, the number of outer cartons matched the Packing List, but inspection upon delivery at the consignee’s site revealed fewer items inside the cartons than stated on the Invoice.
Since there was no shortage in outer packaging quantity, this differs from a case where cartons themselves were lost during sea transport.
The freight forwarder checked the Packing List, Invoice, unpacking photos, inspection records, the sealing status of cartons, and inspection records at the shipping origin. If the outer packaging shows no signs of tampering or damage, focus is placed on verifying packing, shipment quantities, and product details at the loading location.
When the quantity on the B/L refers to outer packaging units, it does not necessarily guarantee the number of items inside. For shortages in inner quantity, not only carrier responsibility but also exporters, manufacturers, packaging providers, and inspection processes need to be investigated.
Example 3: Cases Where Seal Number Mismatches and Quantity Shortages Were Found Simultaneously
Upon arrival of an import container at the warehouse, the seal number on the D/O did not match the seal number on the container. Photos were taken before opening, and after notifying relevant parties, devanning revealed a shortage in part of the cargo.
In this situation, it is important to carefully verify the relationship between the seal number discrepancy and the quantity shortage.
The freight forwarder cross-checked the B/L, Arrival Notice, D/O, EIR, photos of the actual seals, resealing records, whether customs inspections were conducted, devanning records, and warehouse receipt records.
A seal number discrepancy does not immediately confirm theft or pilferage. Possibilities include resealing after customs inspection, document errors, transshipment, or record omissions.
In this case, it was crucial to treat the seal irregularity as an important factor for checking the quantity shortage, but without jumping to conclusions, necessary notifications and document sharing were made with the carrier on the B/L, NVOCC, and insurer.
Common Misunderstandings
| Common Misunderstandings | Actual Considerations | Practical Points |
|---|---|---|
| Quantity shortage definitively means loss during marine transportation | Shortages at the loading port, discrepancies in documentation, CFS operations, devanning, warehousing, domestic delivery, and inspection variances are also possible. | Confirm the point in time when the shortage was discovered and the unit of quantity. |
| If quantity is stated on the B/L, the exact count is guaranteed | B/L quantities may indicate outer packaging units, pallet count, or container numbers, and do not necessarily correspond to the number of items inside. | Avoid confusing B/L quantities with Invoice quantities. |
| If seal numbers match, quantity shortages cannot occur | Even if seal numbers match, shortages from insufficient loading at origin, item count mismatches, documentation errors, or inspection variances can still happen. | Do not rely solely on seal confirmation; verify and reconcile quantity records. |
| If outer packaging count matches, there is no quantity shortage | Even when outer packaging counts are correct, internal quantity shortages or discrepancies in item details may occur. | Confirm outer packaging counts separately from internal counts. |
| Internal quantity shortages are always the responsibility of the carrier | When outer packaging is intact but internal shortages exist, exporters, manufacturers, packing, and inspection processes may be main points for verification. | Check for signs of package opening, seal status, and shipping records. |
| Quantity shortages can be proven with photographs | Missing items cannot be photographed directly, so it is necessary to maintain records of the quantities that existed, comparison sheets, and condition upon opening. | Combine photos with devanning records, warehouse receipts, and inspection reports. |
| If the insurance company is notified, notifying the carrier is unnecessary | Notifying the insurance company of an incident and notifying the carrier or NVOCC shown on the B/L of damage are separate practical procedures. | Manage insurance notifications and carrier notifications concurrently. |
| Only organizing the damage amount is necessary for quantity shortages | Before determining the damage amount, it is necessary to organize the quantity units, discovery timing, segment where it occurred, and notification recipients. | Confirm claim amounts separately from the cause of responsibility. |
Practical Points
Quantity shortages are a type of issue where errors in judgment easily occur if the units of record are inconsistent. It is necessary to separately verify quantities on the B/L, Packing List quantities, outer packaging counts, internal counts, pallet numbers, and case counts.
Freight forwarders should organize B/L, Arrival Notices, D/O, seal numbers, devanning records, warehouse receipts, inspection records, and photos in chronological order, and distinguish whether shortages occurred during international transport, at the origin shipment, or after warehousing/domestic delivery. This is a fundamental practice.
Additionally, with quantity shortages, the missing cargo itself cannot be photographed. Therefore, it is important to keep records that reconcile the condition immediately after opening, the cargo that existed, devanned quantity, warehousing quantity, inspection counts, and quantities stated in documents.
If there is a possibility that the quantity shortage occurred during international transportation, it is advisable to consider notifying the carrier or NVOCC shown on the B/L to protect rights even if the cause or damage amount is not yet confirmed. It is important to manage notifications to the insurance company separately from notifications to the carrier as distinct practical tasks.
Summary
Quantity shortages during marine transportation refer to cases where quantities recorded on documents such as the B/L, Packing List, and Invoice do not match the quantities actually confirmed after import.
Even if a quantity shortage is discovered, it does not immediately confirm loss during marine transport or carrier responsibility. It is necessary to sequentially check for loading shortages at origin, documentation errors, shortages inside the container, missed confirmations during devanning, discrepancies in warehousing records, and quantity differences after domestic delivery.
In practice, distinguish whether the shortage is in outer packaging or internal contents, and reconcile B/L quantities, Packing List quantities, Invoice quantities, devanned quantities, warehousing quantities, and inspection quantities. Seal numbers, photos before opening, devanning records, POD, and delivery receipts are also important reference materials.
Quantity shortages cannot be determined solely by photos or B/L quantities. It is important to separately organize the quantity units, discovery timing, segment of occurrence, notification recipients, and insurance handling. Simultaneously advancing the submission of claim letters to the carrier, notifications to NVOCC, and claims reporting to the insurance company as needed is essential.
