What Is Weight Limitation
Interlink編集部What Is Weight Limitation?
Weight Limitation is the concept of limiting the carrier’s liability amount based on the weight of the cargo.
In maritime transport, even when cargo is lost or damaged, the carrier is not always liable for the full amount of the loss. The liability limits per weight unit may be stipulated by the Bill of Lading’s back terms, international conventions, or domestic laws.
Under Japanese law and the Hague-Visby Rules framework, an important principle is to compare the liability limits per package or unit, equivalent to 666.67 SDR, and per kilogram of the total damaged or lost cargo weight, equivalent to 2 SDR, and apply the higher amount as the basis.
What is crucial with Weight Limitation is not merely reading the Gross Weight stated on the Bill of Lading. In practice, it is necessary to confirm which cargo was lost or damaged, which documents can verify the weight of that cargo, and whether the weight assessments are consistent between the House B/L and the Master B/L.
Terminology Used in This Article
In this article, “carrier” is used as the general legal term for the party whose liability is being assessed under the relevant B/L. “Contracting Carrier” refers to the party that undertakes carriage toward the shipper under the B/L, while “Actual Carrier” refers to the party that actually performs the carriage, especially where this distinction is necessary in House B/L and Master B/L structures.
“Shipping line” is used for the ocean carrier typically appearing under the Master B/L or Ocean B/L. This article does not use “shipping company” or “vessel operator” as separate running terms.
“Shipper” refers to the party that provides shipment instructions, cargo information, packing details, dangerous goods declarations, and other shipment-side declarations. “Cargo owner” is used where the economic cargo interest, claimant, insured party, or party receiving cargo insurance payment is specifically being discussed, especially in cargo insurance and subrogation contexts.

Why Weight Limitation Becomes an Issue
Weight Limitation becomes an issue because the recoverable amount from the carrier varies depending on the cargo weight.
For high-value light cargo, the recoverable amount tends not to increase significantly when calculated based on weight. On the other hand, for heavy cargo such as large machinery, steel products, heavy parts, and industrial equipment, the weight-based limit may exceed the Package Limitation.
In the event of cargo damage, it is essential to verify and reconcile not only the amount of damage but also the weight of the damaged cargo, the weight declared on the B/L, the Packing List, the Invoice, and the survey report, to determine which weight standard should be applied.
| Item to Confirm | Practical Perspective | Documents to Check | Points of Caution |
|---|---|---|---|
| Total Weight on B/L | Check how many kilograms are stated as Gross Weight. | Front side of B/L, Sea Waybill | In cases of partial damage, the total weight on the B/L may not be directly applicable. |
| Weight of Damaged Cargo | Confirm the weight of the damaged or lost portion. | Survey report, Packing List, photos | This is often the most disputed point regarding Weight Limitation. |
| Package Limitation | Compare with the limit per package or unit. | B/L, Packing List, cargo details | Package Limitation may be higher in some cases. |
| Cargo Type | Determine whether the cargo is heavy or high-value light cargo. | Invoice, product details, manufacturer data | Weight Limitation becomes more important for heavy cargo. |
| Containerized Cargo | Check whether the weight is for the entire container or only the damaged items. | Container loading list, EIR, survey report | Do not base the damaged weight solely on the total container weight. |
| Applicable Law | Confirm whether Japanese law, Hague-Visby Rules, or U.S. COGSA applies. | B/L back terms, Paramount Clause | Under U.S. COGSA, package or customary freight unit, not weight, is the basis for limitation. |
Concept of 2 SDR per kg
Under Japanese law and the Hague-Visby Rules regime, liability for damaged or lost cargo is typically limited to an amount equivalent to 2 SDR per kilogram of the cargo involved.
This weight-based limitation is generally applied to the weight of the damaged or lost cargo itself, not the total weight of the entire shipment.
For example, if only part of the cargo in a single container is damaged, the limitation applies to the weight of the damaged portion rather than the whole container’s weight.
Therefore, when handling claims, it is important to verify which cargo items were damaged, their respective weights, and how they are described on the B/L and packing list.
Comparison with Package Limitation
Weight Limitation is used in comparison with Package Limitation.
Package Limitation imposes a liability limit per package or unit. In contrast, Weight Limitation calculates the liability limit based on the weight of the damaged or lost cargo.
Under Japanese law and the Hague-Visby Rules system, the higher of 666.67 SDRs per package or unit and 2 SDRs per kilogram is used as the basis.
| Cargo Example | Package Limitation | Weight Limitation | Practical Perspective |
|---|---|---|---|
| 1 carton, 10 kg of light high-value cargo | Equivalent to 666.67 SDRs | 2 SDR × 10 kg = equivalent to 20 SDRs | Package Limitation tends to be higher. |
| 1 crate, 5,000 kg large machinery | Equivalent to 666.67 SDRs | 2 SDR × 5,000 kg = equivalent to 10,000 SDRs | Weight Limitation tends to be higher. |
| 10 cases, each 200 kg | 666.67 SDR × 10 = equivalent to 6,666.7 SDRs | 2 SDR × 2,000 kg = equivalent to 4,000 SDRs | Package Limitation may be higher. |
| 2 pallets, each 1,500 kg | 666.67 SDR × 2 = equivalent to 1,333.34 SDRs | 2 SDR × 3,000 kg = equivalent to 6,000 SDRs | Weight Limitation becomes important for heavy cargo. |
| 1 container, only 500 kg of cargo inside damaged | Varies depending on package/unit classification. | 2 SDR × 500 kg = equivalent to 1,000 SDRs becomes significant. | Identification of damaged cargo weight, not total container weight, is crucial. |
| Only parts of a single machine damaged | Whether the whole machine is considered one unit is an issue. | The debate is whether to use the parts’ weight or the whole machine’s weight. | Documentation should clearly demonstrate the relationship between damage scope and weight. |
Package Limitation often matters for light, high-value cargo, while Weight Limitation can significantly affect recoverable amounts for heavy cargo.
Differences Between Gross Weight, Net Weight, and Damaged Cargo Weight
In Weight Limitation cases, the key issue is which weight measure is used as the basis.
Typically, the Gross Weight is recorded on the B/L. Gross Weight refers to the total weight including the cargo itself plus packaging materials and other packing.
In contrast, the Invoice and Packing List may show both Net Weight and Gross Weight. Net Weight usually represents the weight of the cargo itself, excluding packaging, so it differs from Gross Weight.
| Weight Description | Meaning | Reference Documents | Notes |
|---|---|---|---|
| Gross Weight | Total weight including packaging materials. | B/L, Packing List | Commonly used as the weight displayed on the B/L, but may not be applicable as-is in cases of partial damage. |
| Net Weight | Weight of the cargo itself. | Invoice, Packing List, product details | Excludes packaging materials, so differs from Gross Weight. |
| Damaged Cargo Weight | Weight of the portion of the cargo that is damaged or lost. | Survey report, repair estimate, parts list, photographs | This weight is often the most disputed in Weight Limitation claims. |
| Container Gross Weight | Total weight of all cargo inside the container. | B/L, VGM, container loading details | If only part of the cargo in the container is damaged, this will not match the damaged weight. |
| Part Weight | Weight on a per-part basis. | Parts list, manufacturer documents, repair estimate | Important documentation in cases of partial damage to machinery or equipment. |
| Repair Scope Weight | Weight corresponding to the scope of repair work. | Repair estimate, manufacturer documents, survey report | Repair cost and weight for liability limitation purposes should be separately organized. |
When calculating liability limits, it is important to confirm whether the weight used is the B/L weight, actual damaged cargo weight, or weight including packaging. Survey reports and packing details play a key role in this verification.
Patterns for Identifying Damaged Weight
In Weight Limitation, accurately identifying the weight of damaged or lost cargo is crucial.
It is relatively straightforward when the entire cargo is lost, but when only part of the cargo is damaged, a component is damaged, or the damage is reparable, determining the scope of the damaged cargo weight becomes a challenge.
| Damage Pattern | Weight Assessment | Required Documentation | Notes |
|---|---|---|---|
| Complete loss or total destruction of cargo | The total cargo weight listed on the B/L or Packing List is typically used as the reference. | B/L, Packing List, Invoice, survey report | Confirm whether the weight on the B/L matches the actual weight. |
| Partial damage to only some of multiple packages | Using the weight of only the damaged packages as the basis may be problematic. | Package-specific Packing List, photos, survey report, in-gate records | Carefully verify whether undamaged portions can be included in the weight. |
| Damage to only parts of a single machine | Whether to base the weight on the parts or on the entire machine is often disputed. | Parts list, repair estimate, manufacturer documents, survey report | Using only the damaged parts as the basis could significantly reduce the limitation amount. |
| Partial value loss due to water damage or contamination | Identify the physical extent and weight of the damaged portion. | Inspection records, photos, survey report, disposal certificates | Commercial value depreciation and weight assessment should be treated separately. |
| Reparable damage | The issue is whether to base on the weight of the repair target or the entire item. | Repair estimate, parts weight list, manufacturer documents, survey report | Separate the limitation of liability based on repair costs from that based on weight. |
| Shortage or pilferage | Confirm the weight corresponding to the missing quantity. | Counting records, Packing List, warehouse in/out records, photos | Verify the correspondence between item count shortage and weight shortage. |
| Partial discard due to temperature-related incidents | Confirm the weight of cargo discarded. | Temperature records, disposal certificates, survey report, inventory records | Distinguish between overall temperature deviations and actual discarded weight. |
| Collapse of cargo within container | Confirm the weight of damaged individual items, pallets, or cases. | Container loading details, unpacking photos, survey report | The total container weight may not always be considered as the damaged weight. |
Under Weight Limitation, documentation proving the correspondence between damage extent and weight is as important as the amount of damage itself.
In Case of Partial Damage
When only a part of the cargo is damaged rather than the entire shipment, the calculation of the Weight Limitation must be handled carefully.
For example, if 2 out of 10 machines are damaged, it becomes an issue whether to base the calculation on the weight of the 2 damaged machines alone or on the total cargo units stated on the B/L.
Similarly, if only some components of one machine are damaged, another point of dispute may be whether to base the calculation on the weight of just those components or the entire machine.
Therefore, it is necessary to organize the relationship between the extent and weight of the damage by preparing detailed damage statements, repair estimates, component weights, survey reports, and photographs.
Points to Note for Container Cargo
For container cargo, the weight shown on the B/L may not always match the actual weight of the damaged cargo.
The B/L often records the total weight per container, but in an actual incident, only part of the cargo inside the container may be damaged.
In such cases, the total container weight cannot necessarily be used as is. Documentation specifying the scope and weight of the damaged cargo is required.
For FCL cargo, terms such as Shipper's Load and Count, Said to Contain, and Shipper-packed Container should also be checked. When the carrier has not inspected the contents, the accuracy of the cargo details and weight statements becomes a separate issue.
Differences from U.S. COGSA
Under U.S. COGSA, the liability limitation is based on USD 500 per package or customary freight unit.
In contrast, the Weight Limitation of 2 SDR per kilogram applied under Japanese law and the Hague-Visby Rules follows a different liability limitation structure.
Therefore, for heavy cargo or large machinery, the amount recoverable can vary significantly depending on whether U.S. COGSA or Japanese law / Hague-Visby Rules apply.
For shipments originating from, destined for, or transiting through the U.S., it is important to check the Bill of Lading’s Paramount Clause, governing law clause, applicable U.S. local clauses, and the segment where the incident occurred.
Differences from Air Transport and Multimodal Transport
Weight-based liability limits are also relevant in air transport. However, the conventions, liability principles, limits, notice requirements, and statutes of limitation differ between maritime and air transport.
In multimodal transport, the applicable liability limits depend on whether the incident occurs during the maritime leg, the air leg, or inland transport.
The Weight Limitation on the Bill of Lading is treated separately from the weight-based liability limits under the Air Waybill.
Points to Note for House B/L and Master B/L
When NVOCCs or freight forwarders are involved, the Weight Limitation must be checked separately for the House B/L and Master B/L.
Responsibility limitations on the House B/L are relevant to the shipper, while the responsibility limits on the Master B/L apply when the NVOCC claims against the shipping line.
The House B/L may show the weight per individual item, whereas the Master B/L often only provides the total container weight.
This discrepancy can lead to situations where the liability amount payable to the shipper does not match the recoverable amount from the shipping line, creating a shortfall risk for the NVOCC or freight forwarder.
Comparison of Freight Forwarder Involvement
| Type of Involvement | Main Role | Aspects to Confirm Regarding Weight Limitation | Practical Considerations |
|---|---|---|---|
| Involved solely as an intermediary or arranger | Not a party to the contract of carriage, involved only as an arranger. | Verify the weight figures on the actual issued B/L, the damaged cargo weight, and the basis for claims. | Even if not the liable party, may become embroiled in disputes due to initial responses or insufficient explanations. |
| Issuing House B/L as an NVOCC | Acts as the Contracting Carrier vis-à-vis the shipper. | Confirm the weight shown on the House B/L, individual package weights, and damaged weight. | There may be discrepancies between the liability amount to the shipper and the recoverable amount under the Master B/L. |
| Using shipping line’s B/L | Arrangements and communication are based on the shipping line’s B/L. | Check the Gross Weight on the Master B/L, total container weight, and the B/L’s back terms. | The weight displayed on the Master B/L alone may not specify the damaged portion’s weight. |
| B/L issued by overseas agent | Need to clarify the relationship between the overseas agent, NVOCC, and freight forwarder. | Confirm whose B/L it is, which terms and conditions apply, and which weight indication is adopted. | If the applicable terms are unclear, the standard weight for limitation of liability will also be uncertain. |
| Arranging door-to-door transport | Coordinate both ocean and inland transport segments. | Check the accident segment, extension of liability limits to inland segments, and damaged weight. | Confirm whether the ocean segment’s Weight Limitation applies also to the inland segment. |
| Receiving subrogation claims from marine cargo insurers | Review defense and recourse strategies as the party being claimed against. | Check insurance payout amount, damaged weight, and responsibility limits on the B/L. | Do not accept the insurance payout amount as the full compensation amount by default. |
| Pursuing recovery claims against the shipping line | Involved as the claimant against the Actual Carrier. | Confirm the damaged weight and liability limit recognized under the Master B/L. | May not match the weight adopted on the House B/L side. |
| Involved in high-value cargo damage cases | Acts as coordinator among parties or handles claim responses. | Cross-check damage amount, damaged weight, Package Limitation, and Weight Limitation. | Avoid acknowledging full damage amount in initial responses. |
Common Practical Issues
| Case | Potential Issue | Documents to Check | Recommended Approach |
|---|---|---|---|
| Total loss of a single large machine | Weight Limitation may be higher than the Package Limitation. | B/L, Packing List, Invoice, survey report | Verify the machine’s total gross weight and compare it with the Package Limitation. |
| Damage to only some parts of a large machine | Whether to apply the weight of the parts or the entire machine is disputed. | Parts list, repair estimate, manufacturer documents, photos | Clarify the relationship between damage extent and weight. |
| Partial cargo wet damage inside a container | Whether the container’s total weight can be used is questioned. | Container packing details, unpacking photos, survey report | Identify the weight of the damaged individual items. |
| Damage to lightweight, high-value cargo | Calculation based on 2 SDR/kg often results in a low recovery amount. | Invoice, Packing List, B/L, cargo details | Compare with Package Limitation and confirm coverage under marine cargo insurance. |
| Weight discrepancies between House B/L and Master B/L | Possible mismatch between liability to the shipper and recoverable amount from the carrier. | House B/L, Master B/L, terms and conditions on both backs | Compare both weight representations and assess recognized damage weight. |
| FCL shipment marked as Shipper's Load and Count | The carrier may not have verified the contents or individual item weights. | B/L, Shipping Instruction, Packing List | Confirm the basis for shipper-declared weight versus actual damaged weight. |
| Incident during shipment to the United States | Package Limit under U.S. COGSA may become an issue. | B/L back terms, Paramount Clause, transport route | Check applicability of U.S. COGSA instead of defaulting to 2 SDR/kg. |
| Receiving a high claim in subrogation recovery | Insurance payout and carrier liability amounts may not align. | Subrogation notice, insurance payout documents, B/L, survey report | Verify damage weight, liability limits, exemptions, and claim filing deadlines. |
Example 1: Total Loss of a Single Large Machine
Consider a case where a single large machine weighing 5,000 kg, packed in one crate, is totally lost during marine transport.
Under Package Limitation, the limit relevant is 666.67 SDR per package. Under Weight Limitation, it is 2 SDR × 5,000 kg = 10,000 SDR equivalent.
| Item | Calculation Method | Example of Liability Limit | Practical Consideration |
|---|---|---|---|
| Package Limitation | 666.67 SDR × 1 package | Equivalent to 666.67 SDR | This calculation treats 1 crate as 1 package. |
| Weight Limitation | 2 SDR × 5,000 kg | Equivalent to 10,000 SDR | Weight-based calculation results in a higher limit. |
| Commonly Applied Standard | Comparison of the higher limit | Equivalent to 10,000 SDR | Weight Limitation significantly affects heavy cargo. |
For large machines, steel, and heavy components, omitting confirmation of the Weight Limitation may risk underestimating the recoverable amount.
Example 2: When Only Part of a Machine Is Damaged
Consider a case where the total weight of a single machine is 5,000 kg, and the weight of the damaged part is 500 kg.
The shipper may claim that the entire machine is commercially unusable, while the carrier may argue that only the 500 kg damaged part is physically affected.
| Perspective | Reference Weight | Calculation Example | Point of Dispute |
|---|---|---|---|
| Considering the whole machine as damaged cargo | 5,000 kg | 2 SDR × 5,000 kg = equivalent to 10,000 SDR | Whether the entire machine can be regarded as damaged cargo is the issue. |
| Considering only the damaged parts | 500 kg | 2 SDR × 500 kg = equivalent to 1,000 SDR | Whether damage can be limited only to the damaged parts is the issue. |
| Difference | Equivalent to 4,500 kg | Equivalent to 9,000 SDR | The discrepancy in recognizing the damaged weight directly corresponds to the risk difference. |
In such cases, documentation such as parts lists, repair estimates, manufacturer statements, survey reports, and photographs are used to specifically organize the correspondence between the damage scope and weight.
Example 3: When Only Part of the Cargo in a Container Is Damaged
Consider a case where the B/L Gross Weight for a 1-container shipment is 20,000 kg, but only 500 kg of cargo inside is damaged by water.
In this situation, the container’s total Gross Weight of 20,000 kg shown on the B/L cannot necessarily be used directly as the basis for Weight Limitation. If the actual damaged cargo weighs 500 kg, the liability limitation may be considered based on the 500 kg.
| Item | Weight | Calculation Example | Points to Check |
|---|---|---|---|
| Total Container Gross Weight | 20,000 kg | 2 SDR × 20,000 kg = equivalent to 40,000 SDR | Only applicable if the entire container is damaged; otherwise, it may not be used as is. |
| Actual Damaged Cargo Weight | 500 kg | 2 SDR × 500 kg = equivalent to 1,000 SDR | The damaged items’ weight must be identified from reliable documentation. |
| Difference | Equivalent to 19,500 kg | Equivalent to 39,000 SDR | There is a significant difference between total container weight and damaged cargo weight. |
For FCL cargo, as the Bill of Lading often includes marks such as Shipper’s Load and Count or Said to Contain, it is also necessary to confirm whether the carrier checked the contents or individual package weights.
Example 4: When Damage Weight Valuation Differs Between House B/L and Master B/L
Consider a case where an NVOCC issues a House B/L and holds responsibility toward the shipper.
On the House B/L side, the entire machine weighing 5,000 kg is treated as damaged cargo, and the NVOCC assumes liability based on 2 SDR × 5,000 kg = 10,000 SDR equivalent.
On the other hand, under the Master B/L, the shipping line may claim that only a 500 kg part was actually damaged and recognizes liability only up to 2 SDR × 500 kg = 1,000 SDR equivalent, leaving the NVOCC potentially exposed to a shortfall risk of 9,000 SDR equivalent.
| Item | Weight Consideration | Calculation Example | Practical Meaning |
|---|---|---|---|
| House B/L Liability | Entire machine 5,000 kg | 2 SDR × 5,000 kg = 10,000 SDR equivalent | The weight adopted for determining liability to the shipper. |
| Master B/L Recoverable Amount | Damaged part 500 kg | 2 SDR × 500 kg = 1,000 SDR equivalent | The weight recognized for claims against the Actual Carrier. |
| Shortfall Risk | Discrepancy in damage weight valuation | 9,000 SDR equivalent | Potentially remains with the NVOCC or freight forwarder. |
Under Weight Limitation, it is not only the weight shown on the B/L but also the extent and weight of actual damage recognized that directly impact the shortfall risk.
Relationship with the Himalaya Clause
Weight Limitation is also related to the Himalaya Clause.
Under a Himalaya Clause, not only the carrier but also their employees, agents, subcontractors, stevedores, terminal operators, inland carriers, and others may invoke the liability limitations stated on the Bill of Lading.
When a shipper, cargo owner, or insurer makes a direct claim against a subcontractor, Weight Limitation may still become an issue.
Expanding the scope of claim recipients beyond the carrier does not necessarily allow avoiding liability limits based on weight.
Challenges in Overcoming Weight Limitation
In certain cases, the carrier may not be able to invoke the Weight Limitation clause.
Typically, this issue arises when the act causing the damage was done intentionally or recklessly, with awareness of the possibility of damage occurring.
This relates to situations under the Hague-Visby Rules and various national laws where liability limits may be lost. However, which standard applies should be confirmed based on the Paramount Clause, governing law, jurisdiction, and the segment of the carriage where the incident occurred.
In Japanese logistics practice, it is generally considered difficult to override the liability limitation. Simple cargo mishandling, operational errors, or lack of attentiveness alone do not automatically nullify the liability limitation.
To disallow the limitation of liability, the carrier’s awareness, the manner of their actions, the cause of the incident, and evidential circumstances must be specifically verified.
Relationship with Cargo Insurance and Subrogation Claims
When cargo insurance is in place, the cargo owner or another insured party may receive insurance proceeds after a cargo incident. After payment, the insurer may pursue subrogation claims against the carrier, NVOCC, freight forwarder, shipping line, or Actual Carrier.
In such cases, Weight Limitation directly affects the amount recoverable from the liable party.
The amount paid to the cargo owner under marine cargo insurance and the amount recoverable from the carrier may not be the same. Weight-based liability limits, Package Limitation, deductibles, the Himalaya Clause, notification deadlines, and time bars all influence the recovery amount.
Even when cargo insurance is provided, confirming the Weight Limitation on the Bill of Lading should not be omitted.
Documents to Verify
| Document | Reason for Verification | Main Points to Check | Points of Caution |
|---|---|---|---|
| House B/L Front | To confirm the basis for determining liability to the shipper. | Cargo quantity, Gross Weight, number of packages, remarks | This serves as the reference document for claims from the shipper. |
| House B/L Back Terms | To check the liability limitations stated on the House B/L. | Weight Limitation, Package Limitation, Paramount Clause | Terms may differ from those on the Master B/L. |
| Master B/L Front | To verify conditions for claims against the shipping line and Actual Carrier. | Total container weight, cargo quantity, transport route | May sometimes show only container-unit weights. |
| Master B/L Back Terms | To confirm the liability limitations of the Actual Carrier. | Paramount Clause, liability limits, exemptions, jurisdiction | Directly affects the recoverable claim amount. |
| Invoice | To verify damage amount and cargo details. | Cargo value, item name, quantity | Cargo value and Weight Limitation amount should be treated separately. |
| Packing List | To check weight by individual item and packaging. | Gross Weight, Net Weight, individual item weight | Important in cases of partial damage. |
| Parts List / Manufacturer Documents | To verify weight of parts in case of damage to components. | Parts weight, component details, scope of replacement | Relevant for disputes over total machinery weight versus parts weight. |
| Repair Estimate | To confirm the scope of repairs. | Replacement parts, repair scope, labor cost, parts weight | Repair costs and liability limits should be checked separately. |
| Survey Report | To confirm damage extent and cause. | Damage condition, estimated cause, photos, weight information | Serves as evidence for damaged weight. |
| Container Loading Details | To identify which cargo inside the container was damaged. | Loading position, individual item weight, pallet configuration | Separate total container weight from damaged weight. |
| Claim Letter | To check claim content and notification timing. | Claim amount, basis for claim, incident details | Do not accept claim amounts before confirming liability limits. |
| Subrogation Documents | To verify the basis for claims from the insurer. | Insurance payout amount, scope of subrogation, cargo owner or insured party, claim target | Confirm insurance payout and carrier liability amounts separately. |
Practical Points for Verification
- Check the Gross Weight stated on the B/L.
- Verify the Net Weight and Gross Weight on the Invoice and Packing List.
- Confirm the scope of the damaged or lost cargo.
- Determine whether the weight of the damaged portion can be identified.
- For partial damage, check the weight of the affected components and the scope of repairs.
- Compare the Package Limitation and Weight Limitation provisions.
- Review the liability rules incorporated by the Paramount Clause.
- Confirm the potential applicability of U.S. COGSA and combined transport regulations.
- Check for weight differences between the House B/L and Master B/L.
- In initial responses, avoid acknowledging the full claimed damage amount and verify applicable liability limits.
Four-Column Checklist
| Situation | Contact Party | Items to Verify | Response if Issues Arise |
|---|---|---|---|
| Upon receiving initial notification of a cargo incident | Shipper, cargo owner, insurer, overseas agent | Confirm claim amount, affected cargo, damage extent, and relevant B/L. | Do not accept full damage amount immediately; respond by confirming B/L terms and liability limits. |
| When verifying weight on B/L | NVOCC, shipping line, overseas agent | Check Gross Weight, number of packages, and container weight on the B/L. | If B/L weight alone is insufficient, request Packing List or detailed weight documentation. |
| If damaged weight is unknown | Surveyor, shipper, warehouse, delivery agent | Confirm which cargo items are damaged and whether their weights can be identified. | Obtain additional photos, inspection records, survey reports, and parts lists. |
| When partial damage or parts damage occurs | Manufacturer, repairer, surveyor | Confirm parts weight, scope of repair, and presence of replacement parts. | Estimate damage using both entire machine weight and parts weight. |
| When comparing with Package Limitation | Internal staff, insurer, legal counsel | Check whether the per-package/unit limit or the weight limit is higher. | Do not rely on just one criterion; calculate both for assessment. |
| When both House B/L and Master B/L are involved | NVOCC, shipping line, overseas agent | Verify weight indications, liability limits, and Paramount Clause on both. | Manage shipper handling and claims against the shipping line separately. |
| For shipments to or from the United States | Overseas agent, shipping line, local counsel | Check U.S. COGSA, U.S. local clauses, and jurisdiction provisions. | Do not assume 2 SDR/kg as default; confirm applicable rules. |
| When receiving a subrogation claim | Cargo owner, marine cargo insurer, shipper, NVOCC, shipping line | Confirm insurance payout, damaged weight, liability limits, exemptions, and claim deadlines. | Separate review of insurance payout and carrier liability amounts. |
Points to Note in Initial Responses
In incidents where Weight Limitation is a concern, it is important to avoid acknowledging the full extent of damages in the initial response.
In practice, it is safer for the initial response to be limited to the following points:
- Acknowledgment of receipt of the claim or notice
- Confirmation that the B/L terms and conditions and liability limitations are being reviewed
- Verification of Weight Limitation and Package Limitation clauses
- Review of damage extent, weight, and cause of the incident
- Statement that liability and the amount of damages are currently undetermined
- Clarification that the response does not imply acceptance of liability

Practical Points to Note
- The core issue with Weight Limitation is how to determine the weight of damaged or lost cargo.
- In addition to the Gross Weight stated on the B/L, the actual weight of the damaged cargo should be verified.
- Net Weight, Gross Weight, and Damaged Cargo Weight should be separately identified and organized.
- For partial damage, confirm the weight of parts, items subject to repair, and the extent of the damage.
- Compare with Package Limitation and verify which limitation applies if there is a conflict.
- Confirm the liability rules incorporated by the Paramount Clause.
- Check for discrepancies in weight declaration between the House B/L and Master B/L.
- When U.S. COGSA applies, do not automatically assume the 2 SDR/kg limitation as a given.
- Initial responses should not admit the full amount of damages but confirm the applicable liability limits.
- In subrogation claims, separate the insurance payout amounts from the carrier’s liability limits for verification.
Summary
Weight Limitation is a concept that limits the carrier’s liability based on the weight of the cargo.
Under Japanese law and the Hague-Visby Rules framework, liability is typically limited to 2 SDR per kilogram of the total weight of damaged or lost cargo. In practice, however, this is compared with the Package Limitation, and the higher amount should be confirmed.
The critical issue with Weight Limitation is not the total weight stated on the Bill of Lading but how the weight of the actual damaged or lost cargo is determined.
If there are differences in the weight declaration or assessment of damaged cargo between the House B/L and the Master B/L, discrepancies can arise between the liability to the shipper and the recoverable amount from the shipping line, leaving a risk of a shortfall for the NVOCC or freight forwarder.
The key takeaway from this article is that Weight Limitation should not be treated simply as a calculation of 2 SDR per kilogram, but rather as a practical judgment involving the scope of damage, weight verification, B/L documentation, and bridging the differences between House B/L and Master B/L.
Important Notes on Marine Cargo Insurance
Marine cargo insurance conditions can vary significantly depending on the coverage terms rather than just the premium. Choosing the right insurance coverage and understanding the policy wording should be consulted with specialized insurance companies or agents.
