SDR (Special Drawing Rights) and Carrier Liability Limits
Interlink編集部What is SDR (Special Drawing Rights)?
SDR (Special Drawing Rights) is an international accounting unit defined by the IMF (International Monetary Fund).
Although SDR is not a currency itself, its value is calculated based on a basket of currencies comprising the US dollar, euro, Chinese yuan, Japanese yen, and British pound.
In Maritime Wiki, SDR is organized not as a general principle of international finance but as a unit used to calculate carriers’ and air carriers’ liability limits.
In cargo incidents, carriers’ liability under B/L terms, international conventions, domestic laws, and transport contracts may be limited in SDR terms. Therefore, SDR plays an important role in cargo claims, carriers’ subrogation, and marine cargo insurance in practice.

Why SDR Becomes Important in Logistics Practice
In international logistics practice, SDR is mainly used to calculate the carrier’s liability limit.
In maritime, air, and multimodal transport, even if cargo damage occurs, the carrier is not always liable to compensate the full cargo value. Liability may be limited to a certain amount by international conventions or transport terms.
SDR is sometimes used as the unit for calculating such liability limits.
Therefore, in cargo incidents, it is necessary to confirm not only the cargo value but also the weight, number of packages, descriptions on the B/L or Air Waybill, applicable terms, governing law, and SDR conversion date.
Main Situations Where the System Applies
| Situation | Why SDR Is Relevant | Documents to Check | Practical Points |
|---|---|---|---|
| Cargo Damage During Maritime Transport | The carrier may assert liability limits in SDR terms based on B/L terms or international conventions. | B/L, Invoice, Packing List, Weight Data, Survey Report | The liability limit may cap compensation below the full cargo value. |
| Damage or Loss of Air Cargo | Air carrier liability limits may be weight-based and calculated in SDR terms. | Air Waybill, Weight Data, Cargo Details, Incident Report | For high-value cargo, the carrier’s liability may not cover the actual loss amount. |
| Subrogation Claims by Cargo Insurers | When insurers claim subrogation against carriers after paying shippers, SDR liability limits become an issue. | Insurance Payment Documents, Claim Letter, B/L, AWB, Survey Documents | Insurance payment amounts and recovered subrogation sums may not match. |
| Liability Limits for Container Cargo | Whether one container counts as a single unit or individual packages are used affects liability limits based on B/L package notations. | B/L, Container Details, Packing List, Shipping Instructions | Package count entries can significantly impact liability limits. |
| Incidents Involving High-Value Cargo | Even with high cargo value, recovery amounts may be limited due to carrier liability limits. | Invoice, Insurance Policy, B/L, AWB, Weight Data | Arranging marine cargo insurance is crucial for precision machinery, electronic components, pharmaceuticals, etc. |
| When Shippers Demand Full Compensation | Shippers may claim full cargo value, but carriers may assert liability limits. | Claim Letters, Damage Details, B/L, Terms, Governing Law | It is important not to respond assuming full compensation will be paid without careful consideration. |
| Settlement Negotiations and Litigation | Conversion date of SDR, conversion currency, and applicability of liability limits may become disputed issues. | Terms, Governing Law, Court Documents, IMF Rates, Damage Documentation | Do not mechanically determine the conversion date; consult with the insurer and legal counsel. |
Relation to Maritime Carrier Liability Limits
In maritime cargo incidents, carriers’ liabilities may be limited in SDR terms based on the Hague-Visby Rules and other frameworks.
A common approach is to compare the limit per package or per unit with the limit per 1 kg of cargo gross weight, with the higher amount being set as the liability limit.
At this point, not only the cargo value is important. The total weight of the cargo, the number of packages or pieces, the units indicated on the B/L, the detailed listing within the container, the applicable terms and conditions, the governing law, and the conversion date of the SDR all become relevant issues.
Especially for container cargo, whether it is stated on the B/L as one container or whether the number of cartons or pallets is clearly indicated can affect the concept of the liability limit.
Relation to Air Carrier Liability Limits
In air cargo as well, international conventions and air transport terms may define the carrier's liability limit in terms of SDR.
In air cargo, liability limits are often calculated based on weight, and for high-value cargo, the carrier's liability limit alone may not cover the actual loss amount.
The liability limits for air cargo under the Montreal Convention may be changed due to international revisions. Therefore, rather than retaining outdated fixed amounts in this article's main text, it is important in practice to confirm the latest liability limits according to the timing of the incident, transport contract, and applicable convention.
For high-value cargo, precision instruments, pharmaceuticals, temperature-controlled cargo, etc., it is important to consider arranging marine cargo insurance rather than relying solely on carrier liability.
Comparison of Liability Limits: Marine vs. Air Transport
| Comparison Item | Marine Transport | Air Transport | Practical Notes |
|---|---|---|---|
| Main Documents | B/L, Sea Waybill, HOUSE B/L, MASTER B/L | Air Waybill, House Air Waybill, Master Air Waybill | Check document weight, number of packages, description, and declared value. |
| Concept of Liability Limit | The system comparing package/unit basis and weight basis is an issue. | Liability limit is mainly calculated based on weight. | Package Limitation is especially important for marine, while limit per kg is especially important for air. |
| Commonly Problematic Entries | Whether recorded as one container or by number of cartons/pallets is a problem. | How to view the damaged cargo weight rather than chargeable weight is an issue. | Weight for freight calculation and weight for liability limit calculation are distinguished. |
| Risk for High-Value Cargo | If the cargo value is high relative to weight or number of packages, the liability limit may be low. | For light-weight, high-value cargo, the liability limit could be far below actual loss. | Marine cargo insurance is important for electronics, pharmaceuticals, and precision equipment. |
| Subrogation Practice | Cargo insurers may subrogate claims to carriers, NVOCCs, and freight forwarders. | Cargo insurers may subrogate claims to airlines and air freight forwarders. | In both cases, liability limits affect subrogation recovery amounts. |
| Parties to Confirm | Shipping companies, NVOCCs, insurers, lawyers, surveyors | Airlines, air freight forwarders, insurers, lawyers, surveyors | Confirm terms and applicable laws for each transport mode. |
Applicable Conditions and Exceptions
| Category | Concept of Application/Exclusion | Documents to Confirm | Notes |
|---|---|---|---|
| Cases where SDR liability limits are relevant | Where the carrier asserts liability limits based on international conventions, domestic laws, B/L or AWB terms. | B/L, AWB, terms and conditions, governing law, incident documents | SDR calculation does not automatically apply merely because a cargo incident occurred. |
| Cases where the full cargo value cannot be the basis | Even if carrier liability is established, compensation may be limited by liability limits. | Invoice, packing list, weight documents, package counts | Separate confirmation for cargo value and liability limit is required. |
| Cases where liability limits may not apply | Intentional acts or gross negligence could cause loss of liability limits. | Accident investigation materials, communication records, carrier behavior logs | Determining loss of liability limits requires advanced legal judgment. |
| Cases handled by shipper's cargo insurance | Cargo insurance covers the cargo owner's loss and its role differs from SDR liability limits. | Cargo insurance policy, incident notification, insurance claim documents | SDR liability limits may arise in subrogation after insurance payment. |
| Cases with unknown terms or governing law | It is not possible to determine which liability system applies. | Terms on the back of B/L, AWB conditions, transport contracts, master service agreements | First confirm applicable terms and governing law. |
| Accidents only during domestic delivery | Different domestic transport terms or contracts may apply separately from international maritime or air liability limits. | Delivery slips, domestic transport terms, delivery records, contracts | Separate incidents in international transport segments from domestic delivery segments. |
| Delay damages and indirect losses | Claims may be made for delay, lost profits, or factory shutdown damages separately from physical cargo damage. | Invoices, contracts, terms, damage details | These are often excluded or limited under carrier liability, so avoid easy acceptance. |
Comparison with Other Systems
| System / Concept | Main Meaning | Relationship with SDR | Documents Checked in Practice | Points to Note |
|---|---|---|---|---|
| SDR Liability Limitation | A mechanism to calculate carrier liability in SDR units. | Used when converting liability limits into yen, US dollars, etc. | IMF exchange rate, B/L, AWB, terms and conditions, weight documents | Check the latest rate and the exchange reference date. |
| Package Limitation | Liability limitation per package or unit. | There are cases where the SDR limit is calculated per number of packages or units. | B/L, Packing List, Shipping Instruction | For containerized cargo, the descriptions on the B/L are important. |
| Weight Limitation | A method to calculate liability limits based on cargo weight. | Sometimes calculated in SDR per kg. | Weight certificates, B/L, AWB, cargo details | Avoid confusing gross weight, damaged cargo weight, and chargeable weight. |
| Liability Limitation in B/L | Carrier liability limits based on the B/L terms and conditions. | SDR-based liability limits may be embedded in the terms and conditions. | B/L front page, reverse side terms, governing law clause | Conditions may differ between HOUSE B/L and MASTER B/L. |
| Marine Cargo Insurance | Insurance covering damage to cargo belonging to the cargo owner. | After insurance claim payment, SDR liability limitations become an issue during subrogation against the carrier. | Insurance policy, incident documents, subrogation records | Insurance sum and subrogation recovery amount may not match. |
| Carrier Exemptions | Reasons for exemption from carrier liability. | If exemption is established, liability may be denied before SDR calculations. | Incident cause documents, terms and conditions, survey reports | Exemptions and liability limitations are separate issues. |
Items to Check When Converting SDR
| Item to Check | Reason for Checking | Documents to Check | Points to Note |
|---|---|---|---|
| Applicable Carriage Terms | To determine which liability limitation system applies. | B/L reverse terms, AWB terms, carriage contract | Conditions may differ between HOUSE and MASTER. |
| Governing Law and Jurisdiction | Affects whether liability limits apply and which conversion date to use. | B/L, AWB, contracts, terms and conditions | Legal judgments may require confirmation with a lawyer. |
| Total Cargo Weight | To calculate the weight-based liability limitation. | Packing List, B/L, AWB, weight certificates | Confirm whether it refers to total cargo or only damaged parts. |
| Number of Packages / Units | To calculate the Package Limitation. | B/L, Packing List, Shipping Instruction | Whether it’s one container, carton count, or number of pallets can be disputed. |
| Descriptions on B/L and AWB | To verify the cargo information recognized by the carrier. | B/L front page, AWB, Booking Confirmation | Check consistency between document descriptions and actual cargo details. |
| SDR Conversion Date | SDR value varies, so amounts change depending on the conversion date. | Terms and conditions, governing law, court documents, insurer calculations | Confirm which date to use: incident date, judgment date, payment date, etc. |
| IMF Published Rate | To convert SDR into yen, US dollars, etc. | IMF public data, insurer calculation sheets | Do not keep fixed conversion rates in the text; always confirm the latest values. |
Application Flow of the System
- Confirm the transport segment where the cargo incident occurred.
- Identify whether it involves ocean, air, multimodal, or domestic transport.
- Check transport documents such as B/L, Sea Waybill, Air Waybill, HOUSE B/L, MASTER B/L, etc.
- Verify applicable terms, governing law, jurisdiction, and international conventions.
- Check if the carrier is liable or if any exemptions apply.
- If liability is possible, confirm whether the liability limitation applies.
- Determine whether to use package/unit basis, weight basis, or compare both.
- Check descriptions on B/L/AWB, cargo weight, number of packages, and damage range.
- Confirm the SDR conversion date and IMF published rate.
- Separate and organize cargo value, insurance payment amount, carrier liability limit, and subrogation amount.
- Coordinate response plans with the cargo owner, insurer, carrier, freight forwarder, lawyer, and surveyor.
Role of Forwarders and Cargo Owners in Practice
SDR is not a currency that freight forwarders or cargo owners routinely use.
However, when a cargo incident occurs and carrier liability or subrogation is considered, liability limits denoted in SDR may become relevant.
In practice, freight forwarders may be asked by cargo owners why the full cargo value cannot be claimed from the carrier. In those cases, it is necessary to explain that carriers have liability limits under the terms and conditions and international conventions, and SDR may be used as the calculation unit.
That said, forwarders are not in a position to make definitive legal judgments. Whether liability exists, the applicability of liability limits, loss of limitation rights, and the conversion date should be confirmed and organized in cooperation with insurers, lawyers, and adjusters.
Relationship with Marine Cargo Insurance
Liability limitations expressed in SDR are also important in marine cargo insurance practice.
When an insurer pays insurance money to the cargo owner and then subrogates against the carrier, the carrier may claim liability limits based on SDR.
In such cases, the insurance payment amount and the amount recoverable from the carrier do not necessarily match.
For example, even if the cargo value is high, if the carrier's liability limit converted to SDR is low, the amount recoverable by the insurance company through subrogation may be limited.
Therefore, it is necessary to separately organize the presence or absence of cargo insurance, the insured amount, deductible amount, subrogation policy, and carrier liability limits.
Checking the IMF SDR Rate
The value of an SDR is checked using the SDR valuation rate published by the IMF.
The IMF calculates the SDR value based on a basket of major currencies and market exchange rates. In practice, the IMF's published rates are referenced when converting liability limits into Japanese Yen or US Dollars.
However, fixing the SDR conversion rate for a specific date within a wiki article becomes outdated over time. Therefore, in practice, it is important to check the latest IMF published values.
Also, the conversion date is not always the date of the incident. Depending on the terms and conditions, applicable law, courts, settlement practice, and insurance company policies, the relevant date could be the judgment date, payment date, settlement date, etc.
Typical Problematic Cases
| Case | What Becomes the Issue | Documents to Check | Practical Response |
|---|---|---|---|
| Cargo was damaged by water during maritime transport | The carrier may claim liability limits in SDR under the B/L terms and conditions. | B/L, Survey Report, Photos, Invoice, Packing List | Confirm presence or absence of liability, exclusions, number of packages and weight, and SDR conversion date. |
| High-value precision machinery was damaged during air transport | The carrier's liability limit based on weight may be lower than the cargo value. | AWB, weight documentation, Invoice, insurance policy, accident report | Separate the existence of marine cargo insurance and carrier liability limits. |
| Marine cargo insurer pursued subrogation claims | There may be a difference between the insurer's paid amount and what can be recovered from the carrier. | Insurance payment documents, subrogation letter, B/L, AWB, survey reports | Check the recoverable amount based on SDR liability limits. |
| Package count description was ambiguous for container cargo | Whether to consider one container as a unit, or count cartons or pallets, becomes the dispute point. | B/L, Shipping Instruction, Packing List, container details | Cross-check the units stated on the B/L against the actual cargo details. |
| The shipper demanded indemnification for the full cargo value | The shipper's claimed amount and the carrier's legal liability limit may not match. | Claim documents, Invoice, B/L, terms and conditions, accident documents | Explain liability limits rather than presuming full payment. |
| Disagreement over the SDR conversion date | Which date's rate to use—incident date, claim date, judgment date, payment date—becomes the issue. | Terms and conditions, applicable law, court documents, IMF rates, insurer's calculation documents | Confirm with the insurance company, lawyers, and adjusters. |
| Claims included delay damages or loss of profit | Indirect damages may be claimed in addition to physical cargo damage. | Claim details, contracts, terms and conditions, accident cause documents | Check whether carrier liability applies, is excluded, or subject to limitation. |
Example 1: When SDR Liability Limits Become an Issue in Water Damage During Maritime Transport
During maritime transport, if cargo inside a container is water damaged, the shipper may claim the full cargo value from the carrier or NVOCC. In such cases, first confirm the cause of the incident and the segment where it occurred. Even if the accident happened during maritime transport and the carrier may be liable, the carrier may invoke SDR liability limits based on B/L terms and applicable laws.
In practice, the B/L, Packing List, Invoice, Survey Report, photos, and weight details are checked. Next, it is confirmed whether package-based limits or weight-based limits apply, or whether they are compared. For container cargo, it is important whether the B/L states one container or specifies cartons or pallets.
It is necessary to explain to the shipper that while they can claim the full cargo value, the amount legally recoverable from the carrier may differ.
Example 2: When High-Value Cargo is Damaged During Air Transport
When high-value precision machinery, electronic components, pharmaceuticals, etc. are damaged during air transport, the carrier’s liability limit may be calculated based on weight, even if the cargo value is high.
For example, with lightweight but high-value cargo, calculation based on liability limits per kilogram may result in a much lower recoverable amount from the carrier than the actual loss. Therefore, in air cargo, relying solely on carrier liability is insufficient; arranging marine cargo insurance on the shipper's side becomes important.
In freight forwarder practice, AWB weight, cargo value, presence of insurance arrangements, declared value, temperature control conditions, and packaging condition are all checked. When handling high-value cargo, it is advisable to explain to the shipper before shipment the difference between cargo insurance and carrier liability limits.
Example 3: When the Marine Cargo Insurer Pursues Subrogation Against the Carrier
After paying insurance benefits to the shipper, the cargo insurance company obtains the shipper's rights to that extent and may pursue subrogation claims against the carrier, NVOCC, airline, warehouse, etc.
At this time, the amount paid by the insurer is not necessarily fully recoverable from the carrier. Even if the carrier is liable, recovery may be limited due to SDR liability limits under the terms and international conventions.
In practice, the insurance payment amount, subrogation letter, B/L or AWB, accident cause documents, liability limits, and SDR conversion date are organized. The party subject to subrogation should not make payment decisions based solely on the claimed amount but must check liability and liability limits.
Example 4: When Package Counts on the B/L for Container Cargo Become a Dispute
For container cargo, sometimes the B/L only states "1 Container," and other times the number of cartons, pallets, or cases inside the container is specified.
When calculating carrier liability limits, how one views a single package or unit can significantly impact the liability ceiling. If the number of cartons is explicitly stated, calculations may be based on that information. On the other hand, when only a single container is noted, the liability limit could vary considerably.
In actual logistics practice, it is essential to cross-check the Shipping Instruction, Packing List, B/L draft, and final B/L to confirm that the cargo details intended by the shipper are correctly reflected on the B/L. Since it is difficult to revise the package count after an incident, pre-shipment document verification is crucial.
Four-Column Decision Checklist
| Situation for Verification | Party to Confirm With | Items to Confirm | Actions if Issues Are Found |
|---|---|---|---|
| Immediately After Incident | Shipper, Consignee, Warehouse, Delivery Company | Date and time discovered, location found, cargo condition, extent of damage | Preserve the actual cargo, take photographs, arrange for survey. |
| Confirming Transport Segments | Shipping Line, Airline, NVOCC, Freight Forwarder | Determine at which point maritime, air, domestic delivery, or warehouse handling the incident possibly occurred | Organize liable parties and applicable terms per transport segment. |
| Reviewing Shipping Documents | Shipper, Freight Forwarder, NVOCC, Airline Agent | B/L, AWB, HOUSE, MASTER, terms and conditions, governing law | Verify the liability limitation system and applicable conditions. |
| Confirming Number of Packages and Weight | Shipper, Packing Company, Warehouse, Freight Forwarder | Total cargo weight, damaged cargo weight, number of packages, B/L/AWB descriptions | Check for discrepancies between Packing List and transport documents. |
| Converting SDR | Insurance Company, Lawyer, Adjuster | Conversion date, IMF rate, conversion currency, liability limit | Do not convert mechanically based only on the incident date; confirm applicable standards. |
| Explaining to the Shipper | Shipper, Sales Representative, Incident Response Staff | Cargo value, carrier liability, marine cargo insurance, recoverable amount differences | Do not guarantee full compensation; explain the possibility of liability limits. |
| When Subrogation is Claimed | Marine Cargo Insurance Company, NVOCC, Carrier | Claim amount, insurance payment, liability limits, deductibles, cause of incident | Share the information early with your insurance company and legal counsel. |
| When Shipping High-Value Cargo | Shipper, Insurance Company, Freight Forwarder | Cargo value, marine cargo insurance, liability limits, declared value | Arrange cargo insurance and explain risks before shipment. |
Common Misunderstandings
| Misunderstanding | Correct Understanding | Practical Notes |
|---|---|---|
| SDR is a foreign currency actually used | SDR is not a currency itself; it is an international accounting unit defined by the IMF. | In practice, liability limits are confirmed after converting to Japanese Yen or US Dollars. |
| The carrier pays full compensation if cargo is damaged | Even if the carrier is liable, compensation amounts may be limited by liability restrictions. | Explain cargo value, liability limits, and cargo insurance separately. |
| SDR conversion is always based on the incident date's rate | The conversion date may vary depending on terms, governing law, court decisions, or settlement practices. | Check with insurance companies, lawyers, and adjusters. |
| Liability limits are the same for sea and air transport | Sea and air transport differ in applicable conventions, terms, and calculation methods. | Verify B/L and AWB separately. |
| If marine cargo insurance is in place, SDR is irrelevant | After insurance payouts, subrogation claims involve SDR liability limits issues. | Insurance payout amounts and recoveries from carriers may not match. |
| One container is always treated as one package | Package counts and units depend on B/L entries and cargo details. | Confirm package counts on B/L prior to shipment. |
| It is sufficient to include the latest SDR conversion amount in the article text | Because SDR amounts fluctuate, leaving fixed figures in the article will become outdated. | In practice, check IMF published rates each time. |
| If there is a liability limit, the carrier only needs to pay that amount | Deductibles may negate liability entirely, and in some cases, liability limits may be lost. | Separate deductibles, liability determination, liability limits, and loss of liability limits when checking. |
Points to Note
SDR is not a currency but an international accounting unit established by the IMF. It sometimes appears as a standard for calculating carrier liability limits in cargo incidents.
It is not always possible to recover the full cargo value from the carrier. Liability limits vary depending on terms and conditions, international conventions, domestic laws, and governing law.
Sea and air transport adopt different concepts regarding liability limits. For container cargo, how package counts and units are recorded on the B/L may become critical.
Since SDR conversion amounts fluctuate, avoid leaving fixed figures in the article text. In practice, verify IMF published rates, conversion dates, applicable terms, and governing law each time.
During subrogation or litigation, conversion date, applicability of liability limits, and loss of liability limits may become issues. It is important to consult insurance companies, legal counsel, and adjusters as needed.
Summary
SDR is an international accounting unit defined by the IMF, playing an important role in international logistics practice when calculating carrier liability limits.
In cargo incidents, it is crucial to confirm cargo value, weight, package counts, B/L or Air Waybill entries, applicable terms and conditions, governing law, and SDR conversion date to clarify the recoverable range from the carrier.
In maritime transportation, issues often arise regarding the comparison between package/unit-based and weight-based limits, the description of container cargo on the B/L, and package limitation. In air transportation, weight-based liability limits can impact the recovery amount for high-value cargo.
Even when cargo insurance is in place, the SDR liability limits become an issue at the stage where the insurer seeks subrogation against the carrier. It is fundamental for shippers, freight forwarders, NVOCCs, and insurance practitioners to separately organize the cargo value, insured amount, carrier’s liability limit, and the recoverable amount.
