Multilateral Treaties — Key Conventions Referenced in International Logistics and Maritime Transport

What Are Multilateral Treaties?

Multilateral treaties are international agreements concluded by three or more countries.

In fields such as international logistics, maritime transport, customs clearance, marine insurance, cargo incidents, and carrier liability, common rules are often established not only by domestic laws of individual countries but also through multilateral treaties.

On Maritime Wiki, multilateral treaties are treated not as general legal terms but as an index and guide article organized by field for key treaties referenced in international logistics and marine cargo insurance practice.

In practice, simply knowing the treaty name is not enough. It is necessary to check which countries are contracting parties, when it entered into force, whether it has been incorporated into domestic law, and which transport segments, cargo types, or incidents it applies to.

What Are Multilateral Treaties?

Multilateral treaties are international agreements in which multiple countries establish common rules.

While bilateral treaties are concluded between two countries, multilateral treaties involve three or more countries, making them important for creating common rules in international trade, transport, environmental protection, damage compensation, and ship safety.

In international logistics, cargo moves through multiple countries, involving multiple parties such as shipping companies, freight forwarders, shippers, insurance companies, ports, customs, and surveyors.

Therefore, when accidents or disputes occur, it is necessary to check applicable multilateral treaties involved rather than deciding solely based on the domestic law of one country.

Why Check Multilateral Treaties in Practice?

Multilateral treaties affect areas such as the scope of liability, limits of liability, claim deadlines, environmental responsibility, ship safety, customs procedures, and labor standards in international logistics.

For example, if cargo is damaged during maritime transport, one checks the B/L terms, Hague Rules, Hague-Visby Rules, domestic law, and the transport contract.

In the case of oil pollution or dangerous goods incidents, treaties such as the CLC Convention, Fund Convention, Bunkers Convention, and HNS Convention can become relevant.

Ship safety and dangerous goods transport involve treaties like SOLAS, MARPOL, STCW, IMDG Code, and others.

Thus, multilateral treaties are practical information directly linked to accident response, insurance claims, subrogation, defense, customs clearance, and carrier selection—not merely theoretical international law knowledge.

Conventions Related to Maritime Safety

A key example of multilateral conventions concerning maritime safety is the SOLAS Convention.

The SOLAS Convention is an important treaty that sets standards for ship construction, lifesaving appliances, fire safety, radio communication, navigation safety, dangerous goods transport, security, and international safety management.

To freight forwarders and shippers, SOLAS may appear to be a convention only applicable to carriers. However, through aspects such as VGM, IMDG Code, ISPS Code, ISM Code, container loading, ship fires, and dangerous goods acceptance conditions, it impacts actual logistics practice.

In ship accidents or container fires, safety management and dangerous goods management under SOLAS may become underlying issues.

Conventions Related to Marine Environmental Protection

The representative convention regarding marine environmental protection is the MARPOL Convention.

MARPOL regulates oil, harmful liquid substances, packaged harmful substances, sewage, waste, air pollution, and more from ships.

This affects practical matters such as oil pollution incidents, chemical spills, bunker oil contamination, marine pollution, port authority responses, fines, removal costs, and P&I insurance.

MARPOL Annex VI relates to air pollution, fuel sulfur content limits, EEXI, CII, GHG reduction, etc., impacting freight rates and environmental surcharges.

It is important to note that environmental regulation conventions impact not only carriers but also shippers’ supply chain management and insurance practice.

Conventions Related to Crew and Labor

Key multilateral conventions related to seafarers include the STCW Convention and MLC 2006.

The STCW Convention sets standards for seafarer training, certification, and watchkeeping.

In ship accidents or PSC Detention, crew qualifications, watchkeeping systems, fatigue management, and training status may become issues.

MLC 2006 governs seafarers’ working conditions, living environment, wages, health, and welfare.

While shippers and freight forwarders may rarely directly handle these conventions, they may become relevant in cases of ship delays, PSC Detention, validation of carrier risks, and P&I insurance matters.

Conventions Related to Maritime Carrier Liability

Conventions on maritime carrier liability include the Hague Rules, Hague-Visby Rules, Hamburg Rules, and Rotterdam Rules.

The Hague Rules and Hague-Visby Rules are important for organizing carrier responsibility, exemptions, liability limits, notification, and claim deadlines in maritime cargo transport under Bills of Lading.

In cargo incidents, it is necessary to check the B/L terms, governing law, jurisdiction, carriage segments, and liability limit amounts.

Hamburg Rules and Rotterdam Rules require verification of international discussion status and applicability in certain countries.

In practice, it is important not to rely solely on the convention name but to confirm which rules are incorporated in the B/L and which country’s law applies.

Conventions on Liability Limitation

In maritime areas, the liability of shipowners and carriers is not unlimited but may be restricted under certain conditions.

The LLMC Convention (Convention on Limitation of Liability for Maritime Claims) is a significant treaty defining liability limits for maritime claims against shipowners, etc.

In cases of cargo damage, port facility damage, collisions, sinking, and removal costs, liability limitation systems may become an issue even if damage amounts are large.

Whether liability limitation applies depends on the convention, domestic law, the nature of the incident, intent or gross negligence, and claim details.

In insurance practice, confirming liability limitation conventions is important since actual damage and legally recoverable amounts may not align.

Conventions on Oil Pollution and Contamination Damage

Conventions related to oil pollution and contamination damage include the CLC Convention, Fund Convention, and Bunkers Convention.

The CLC Convention establishes shipowner liability for oil pollution damage from tankers.

The Fund Convention provides additional compensation for damages exceeding compensation under the CLC Convention, funded by contributions from the oil receivers.

The Bunkers Convention establishes shipowner responsibility and compulsory insurance for pollution damage caused by ship fuels.

These conventions relate to P&I insurance, oil pollution incidents, port authority responses, environmental damage, compensation funds, and compulsory insurance certificates.

Conventions on Hazardous and Harmful Substances

A representative convention related to hazardous and harmful substances is the HNS Convention.

The HNS Convention sets shipowner liability and compensation through the HNS Fund for damage caused by hazardous and harmful substances during maritime transport.

The substances covered relate to classifications in the IMDG Code, IBC Code, IGC Code, IMSBC Code, and others.

In incidents involving dangerous goods containers, chemicals, liquefied gases, or bulk hazardous cargo, it is necessary to check not only the HNS Convention but also the IMDG Code, SDS, dangerous goods declarations, B/L notation, P&I insurance, and cargo insurance.

The status of entry into force and domestic legislation should always be confirmed, positioning the convention as a framework for future practical logistics implementation.

Conventions on Wreck Removal and Salvage

Multilateral conventions concerning wreck removal and salvage also relate to maritime insurance and P&I insurance practices.

The Nairobi Wreck Removal Convention addresses wreck removal responsibilities, compulsory insurance, and certificates.

If a vessel sinks or grounds and creates navigational hazards or environmental risks, authorities may issue removal orders.

The Salvage Convention concerns marine salvage and salvage rewards.

Issues related to general average, salvage fees, cargo insurance, P&I insurance, and hull insurance sometimes involve these conventions and related rules.

Conventions on Road, Air, and Multimodal Transport

In international logistics, it is necessary to also confirm multilateral conventions related to road and air transport as well as maritime transport.

The CMR Convention governs international road transport of goods and is important mainly in Europe.

In multimodal transport, including inland Europe carriage, whether the road segment is subject to the CMR can become an issue.

In air transport, the Montreal Convention governs air carrier liability, liability limits, and claim deadlines.

In multimodal transport combining sea, road, and air, different conventions may apply depending on the transport segment where an incident occurs, so confirming the exact location of the incident is important.

Conventions on Customs Clearance and Transport Facilitation

Multilateral conventions on customs clearance and facilitation of international transport include the TIR Convention and the Container Convention.

The TIR Convention relates to simplifying customs procedures for international road transport.

The Container Convention concerns the temporary import and customs procedures for containers.

These are not core conventions for marine cargo insurance but are important for understanding customs and transport procedures in international logistics.

Especially for land transport, multimodal transport, and transit transport in Europe, Central Asia, and the Middle East, conventions different from those for maritime transport may be relevant.

Entry into Force, Ratification, and Domestic Legislation of Conventions

Multilateral conventions do not automatically apply to all countries once adopted.

Each country must complete procedures such as signing, ratification, accession, or acceptance to meet the conditions required for the convention to enter into force.

Even if a convention is in force, it may not apply in relation to a country that is not a contracting party.

Some conventions are only practically applicable once countries incorporate them into domestic law.

In practice, it is necessary to check not only the treaty text but also the date of entry into force, contracting parties, reservations, declarations, and domestic legislation status.

Depositary and Checking Convention Information

Multilateral conventions typically appoint a depositary who manages the original texts, contracting party information, ratification status, reservations, and declarations.

The UN Secretary-General is often the depositary for many conventions, and the UN Treaty Collection is a representative source for checking multilateral conventions.

For maritime conventions, it is important to check the IMO official site and the Status of IMO Treaties.

Since treaty statuses can change, caution is needed not to rely solely on secondary information or outdated materials.

Determining the applicability of a convention in practice requires combining official information, domestic laws, B/L terms, insurance certificates, and expert confirmation.

Points Freight Forwarders and Cargo Owners Should Confirm

Freight forwarders and cargo owners are not required to memorize all multilateral treaties.

However, in case of accidents or disputes, they need to identify which treaties might be involved.

For cargo incidents, check the B/L, transport segments, transport mode, accident location, carrier, governing law, and jurisdiction.

For dangerous goods incidents, review the IMDG Code, SDS, dangerous goods declarations, HNS Convention, P&I insurance, and cargo insurance.

Marine pollution and ship incidents may involve MARPOL, CLC, Bunkers, LLMC, and P&I insurance.

For multimodal transport, verify that not only the maritime segment but also road and air segments may fall under different treaties.

Comparison Table of Freight Forwarder Involvement Scope

Scenario	Support Easily Provided	What Should Not Be Conclusively Decided	Practical Response
Maritime Cargo Incident	Organize B/L, transport segments, ship line notifications, survey documents	Final judgment on applicability of Hague-Visby Rules or liability amount	Confirm transport terms, governing law, and notify insurance companies.
Dangerous Goods Incident	Organize SDS, dangerous goods declarations, IMDG classification, ship line declarations	Final determination of compensation applicability under HNS Convention or legal liability	Verify dangerous goods information transmission history and B/L entries.
Oil Pollution / Environmental Incident	Organize accident reports, port authority notifications, P&I information, vessel information	Specific compensation decisions under CLC, Bunkers, Fund Convention	Check vessel type, oil type, location, and compulsory insurance certificates.
Multimodal Transport Incident	Organize materials by road, sea, air, and domestic delivery segments	Legal judgment on which treaty applies ultimately	Confirm accident segments, delivery records, and transport documents by segment.
Customs Clearance / Transport Facilitation	Check customs documents, TIR, container-related documents, transit information	Final customs authority decisions or violation determinations	Verify with customs brokers, overseas agents, and authority announcements.
Insurance / Subrogation Response	Organize cargo insurance policies, P&I information, accident documents, and claim documents	Final decision on insurance payment, success of subrogation, or liability limit amounts	Coordinate with insurers and preserve evidence documents.

Relation to Marine Cargo Insurance and P&I Insurance

Multilateral treaties also affect the practical operations of marine cargo insurance and P&I insurance.

Cargo insurance issues include accident causation, general average, salvage charges, claims against carriers, liability limits, and claim deadlines.

P&I insurance concerns shipowner liability, oil pollution liability, wreck removal, dangerous goods incidents, general average, port facility damage, crew, and third-party liability.

Even when insurance payouts are made, the amount insurers can recover from carriers or third parties may be influenced by treaty liability limits.

Therefore, in insurance practice, it is necessary to confirm not only the damage amount but also who is liable under which treaty and to what extent their liability is limited.

Decision-Making Checklist

Confirmation Scenario	Parties to Confirm With	Items to Confirm	Actions When Problems Arise
When a cargo incident occurs	Shipping company, freight forwarder, shipper, insurance company	Incident segment, transport mode, B/L, carriage contract terms, cause of incident	First organize which segment it concerns: maritime, road, air, or domestic delivery.
When confirming applicability of conventions	Overseas agents, shipping company, experts, insurance company	Contracting states, effective date, domestic legislation, reservations, declarations	Cross-check official information with contract documents, avoid judging based only on outdated sources.

When considering insurance claims and subrogation	Cargo insurance company, P&I Club, lawyers, freight forwarder	Liability limits, claim deadlines, statutes of limitation, recoverable amount, insurance coverage scope	Check damage amounts separately from legally recoverable amounts.

Information and Documentation to Confirm

When confirming the applicability of multilateral conventions, check the following information and documents.

• Convention text
• List of contracting states
• Effective dates
• Ratification/accession status
• Reservations and declarations
• Status of domestic legislation
• B/L or Sea Waybill
• Carriage contract terms
• Charter party agreements
• Cargo insurance policy
• P&I insurance information
• Accident report
• Survey Report
• Dangerous goods declaration
• SDS
• PSC records
• Class information
• Customs documents

When judging convention applicability, it is important to check contract documents, incident materials, and insurance documents together with the convention text.

Common Practical Issues

Case	Frequently Problematic Points	Documents to Check	Practical Measures
Cargo damage during sea transport	B/L terms, Hague Rules, Hague-Visby Rules, liability limits, limitation periods are central issues.	B/L, Sea Waybill, accident report, Survey Report, cargo insurance policy	Confirm incident segment, governing law, carrier liability, and notification to insurance company.
Hazardous material container fire incident	IMDG Code, SDS, dangerous goods declaration, HNS Convention, shipper liability are key concerns.	SDS, dangerous goods declaration, B/L, loading records, shipping company notifications	Check declaration and transmission history of hazardous material information.
Tanker oil pollution accident	CLC Convention, Fund Convention, MARPOL, and P&I insurance are major considerations.	Accident report, oil type, vessel information, compulsory insurance certificate, P&I information	Verify vessel type, location of incident, contracting states, and compensation systems.
Bunker oil spill accident	Bunkers Convention, shipowner liability, compulsory insurance, port authority response are concerns.	Fuel oil data, authority notifications, P&I certificates, removal cost details	Differentiating whether it is fuel oil contamination or tanker oil pollution.
Accident during inland transport in Europe	CMR Convention, liability limits for road segment, statutes of limitation, CMR waybill issues	CMR waybill, road haulage contracts, pickup and delivery locations, accident report	Separate maritime and road segments and identify accident segment.
Unclear accident segment in multimodal transport	Disputes around which rules apply: maritime, road, air, warehouse regimes	Delivery records, photos, B/L, CMR waybill, AWB, delivery slips	Organize cargo condition at each handover point and check liability per segment.
Costs arising from wreck removal	Nairobi Wreck Removal Convention, P&I insurance, shipowner liability issues	Authority orders, sinking/grounding information, P&I certificates, removal cost statements	Confirm removal orders, compulsory insurance, and liability limits.
Delays caused by ship PSC Detention	SOLAS, STCW, MLC 2006, ship safety management, seafarer qualifications as background issues	PSC records, class information, shipping company notices, delay notifications	Confirm cause of delay, shipping company risks, and contract-based delay exemptions.

Example 1: Cargo Damage During Sea Transport

When container cargo is damaged during sea transport, first verify the B/L terms and governing law.

If the Hague Rules or Hague-Visby Rules apply, the carrier’s liability, exemptions, liability limits, notification deadlines, and limitation periods become key issues.

In this case, the shipper should check for marine cargo insurance coverage; the freight forwarder should confirm the B/L and the accident segment; and the insurance company should consider the possibility of subrogation.

Example 2: Hazardous Material Incident

If a hazardous material container is suspected as the cause of a fire on board, verify the IMDG Code compliance, SDS, dangerous goods declaration, and B/L notations.

If hazardous material information notification is insufficient, the shipper or freight forwarder’s liability could be questioned.

The HNS Convention and P&I insurance issues may also be relevant.

In this case, the shipper should have accurately notified the hazardous materials information, and the freight forwarder should have reliably communicated the declaration details to the shipping company.

Example 3: Oil Pollution Incident

Tanker accidents and fuel oil spill incidents involve the CLC Convention, Fund Convention, Bunkers Convention, MARPOL, and P&I insurance.

Compensation to victims, shipowner liability, compulsory insurance, compensation from funds, and regulatory responses become key issues.

In this case, it is necessary to confirm the type of oil involved in the accident, vessel type, the sea area where the incident occurred, contracting states, and compulsory insurance certificate.

Example 4: Accident During Inland Transport in Europe

For cargo damage during road transport within Europe, the CMR Convention may apply.

Even for intermodal transport from Japan to Europe, rules applicable to the maritime and road segments may differ.

In this case, it is necessary to confirm the segment where the accident occurred, the carrier, the CMR consignment note, liability limits, and notification deadlines.

Common Misunderstandings

Misunderstanding	Correct Understanding	Practical Notes
Knowing the name of the convention is enough for practical decision-making	The name alone is insufficient; it is necessary to check contracting states, entry into force status, incorporation into domestic law, and contractual documents.	Check official information, B/L clauses, insurance policies, and domestic laws together.
International conventions always directly apply to international transport	Whether a convention applies depends on transport segments, contracting states, contract type, and domestic legislation.	Separate confirmation for maritime, road, air, and domestic delivery segments is needed.
There is only one applicable rule for the same cargo accident	In multimodal transport, different conventions and clauses may apply for maritime, road, and air segments.	Identifying the accident segment is essential.
The actual amount of damage can always be fully recovered despite liability limits under conventions	Liability limits may cause the legally recoverable amount to differ from the actual loss.	Separate confirmation of cargo insurance, P&I insurance, and liability limits is required.
Once a convention is adopted, it can be used in any country	It is necessary to confirm not only adoption but also entry into force, ratification, accession, incorporation into domestic law, reservations, and declarations.	Check the list of contracting states and effective dates.
Insurance company payment absolves responsibility under the convention	Subrogation by the insurer involves issues of liability limits and claim deadlines under the convention.	Confirm the recoverable amount after insurance payout.
Freight forwarders do not need to check conventions	Freight forwarders have a practical role in organizing accident segments, transport modes, B/Ls, hazardous goods information, and insurance responses.	Do not make definitive legal judgments; organize necessary documents and connect to specialists or insurers.

Points of Caution

Multilateral conventions cannot be practically applied by only knowing their names.

Whether they apply depends on contracting states, entry into force status, domestic legislation, transport segments, contractual documents, governing law, and accident location.

Even in the same cargo accident, applicable conventions and liability rules may differ for maritime, road, air segments, or warehousing.

Additionally, if the convention limits liability, the actual damage and the recoverable amount may not match.

In insurance practice, it is necessary to separately check liability under the convention and coverage under the insurance policy.

Summary

Multilateral conventions form the basic international rules underlying international logistics, maritime transport, customs, marine cargo insurance, cargo accidents, and carrier liability.

At Maritime Wiki, multilateral conventions are positioned not just as legal terminology, but as an index of practical conventions such as SOLAS, MARPOL, Hague-Visby Rules, LLMC, CLC, HNS, CMR, and MLC 2006, which are referenced in actual business practice.

Freight forwarders, shippers, and insurance practitioners need to confirm which conventions are relevant in accidents or disputes, which countries are contracting states, whether the conventions have been incorporated into domestic law, and what rules are included in contractual documents.

Understanding multilateral conventions is a prerequisite to properly organizing accident response, insurance claims, subrogation, defense, liability limits, and customs procedures.
