An Overview of Coverage and Key Legal Considerations for Different Types of Marine Insurance Policies
Maritime transportation is a primary method of transporting goods in international trade. Large cargo volumes, long shipping distances, changing weather conditions, the possibility of accidents at ports and at sea, and the complexity of loading and unloading operations expose cargo owners and transportation companies to various risks. Consequently, marine insurance policies play an important role in managing potential losses and reducing the risks associated with commercial activities.
Marine insurance is a contractual arrangement under which an insurer, in exchange for an insurance premium, undertakes to indemnify the insured against specified losses arising from covered risks. The extent of the insurer’s obligations depends on the type of insurance policy, its general and special conditions, applicable exclusions, and any endorsement provisions.
This article examines the different types of marine insurance policies, their common coverage provisions, and the important legal considerations associated with their issuance and use.
What Is a Marine Insurance Policy and What Are Its Applications?
A marine insurance policy is a contract that establishes the insurer’s and the insured’s obligations for specified risks associated with maritime transportation. Such insurance may cover cargo, vessels, maritime equipment, or liabilities arising from maritime operations.
For example, consider a company shipping a consignment of raw materials by sea from a port in China to Bandar Abbas, Iran. During the voyage, the vessel may encounter adverse weather conditions, part of the cargo may be damaged by water ingress, or losses may occur during unloading operations.
If the relevant risk is covered under the insurance policy and the other conditions for indemnification are satisfied, the insurer must compensate the insured within the limits of its contractual liability.
Marine insurance serves several important purposes in international trade:
- Reducing financial losses arising from damage to or destruction of cargo.
- Protecting shipowners and vessel operators against operational risks.
- Providing coverage for certain legal liabilities of vessel owners and operators.
- Enhancing security and confidence in import and export transactions.
- Supporting risk management in transportation contracts and supply chain operations.
Types of Marine Insurance Policies by Subject Matter
Marine insurance policies can be classified into several principal categories according to the subject matter insured. Each category protects different assets and financial interests.
Marine Cargo Insurance
Marine cargo insurance is one of the most common forms of insurance used in international trade. It provides coverage for loss of or damage to goods during transportation, subject to the terms, conditions, and scope of coverage specified in the policy.
Marine cargo insurance policies may cover shipments of raw materials, industrial products, machinery, equipment, food products, commercial goods, and export commodities.
Depending on the contractual arrangements, insurance coverage may commence when the goods are dispatched from their point of origin and continue until they reach their final destination.
In multimodal transportation, the policy may also cover inland transportation, maritime transportation, and other stages of the journey.
Marine cargo insurance may be classified according to the transportation route as follows:
- Import Cargo Insurance: Covers goods purchased from foreign countries and imported into the country.
- Export Cargo Insurance: Covers shipments transported from Iran to destinations in other countries.
- Transit Cargo Insurance: Covers goods passing through one country when their final destination is in another country.
- Domestic Cargo Insurance: Covers shipments transported between points of origin and destination within Iran’s geographical boundaries. Although this type of insurance is more commonly associated with inland transportation, it also falls under the broader classification of transportation insurance.
Hull and Machinery Insurance
Hull and Machinery Insurance, commonly referred to as H&M Insurance, protects the vessel itself and its associated machinery and equipment.
Under this type of insurance, the insured value of the vessel’s hull, engines, technical equipment, and other components specified in the policy is particularly important.
Depending on the policy’s terms and conditions, it may cover risks such as collisions with other vessels, grounding, sinking, fire, and certain maritime accidents.
The scope of H&M coverage depends on several factors, including the type of vessel, operating conditions, trading routes, technical condition, and the agreement between the insurer and the insured.
Protection and Indemnity (P&I) Insurance
Insurance covering shipowners’ liabilities is commonly known as Protection and Indemnity Insurance, or P&I Insurance.
This form of insurance covers certain legal liabilities incurred by shipowners or vessel operators toward third parties.
For example, during vessel operations, cargo belonging to another party may be damaged, crew members may be injured, or pollution caused by the vessel may damage third parties or their property.
Depending on the applicable insurance contract or P&I club membership terms, certain liabilities arising from these incidents may be covered.
Maritime liability insurance covers personal injury claims, cargo-related liabilities, crew liabilities, and marine pollution.
Container Insurance
Containers are essential components of international transportation and may be exposed to theft, accidental falls, collisions, fires, and physical damage during their use.
Container insurance is designed to provide compensation for loss of or damage to the container itself.
This coverage is distinct from insurance covering the cargo stored inside the container.
Consequently, cargo owners and container owners should determine which insurance policies cover their respective assets and ensure that the scope of coverage is clearly established.
Shipbuilders’ and Ship Repairers’ Liability Insurance
Shipbuilding, vessel maintenance, and repair operations involve numerous technical and financial risks.
Shipbuilders’ and Ship Repairers’ Liability Insurance is designed to cover certain losses and liabilities arising from these activities.
Depending on the contractual provisions, the insurance may cover liabilities associated with vessel construction, repairs, testing, and delivery.
The project’s nature should determine the scope of coverage, the stage of construction or repair, and the contractual responsibilities assumed by the contractor.
Types of Marine Insurance Policies by Scope of Coverage
One of the most important factors in selecting cargo insurance is the range of risks the insurer agrees to indemnify.
In international cargo insurance, the standard Institute Cargo Clauses are commonly classified into three principal categories: Clauses A, B, and C.
These categories differ in the extent of the risks covered.
Institute Cargo Clauses (A)
Institute Cargo Clauses (A) provide the broadest level of coverage among the three principal sets of standard cargo insurance clauses.
Under this form of insurance, loss of or damage to the insured cargo resulting from insured risks is generally covered, except where the loss falls within the exclusions specified in the policy.
For example, damage caused by cargo falling during loading operations, damage resulting from collisions, or certain unexpected incidents may be covered, provided that the relevant policy conditions are satisfied.
Despite being commonly described as all-risks coverage, Clause A does not provide compensation for every possible loss under all circumstances.
Risks associated with the inherent nature of the goods, inadequate packaging, delay, deliberate misconduct by the insured, and certain other circumstances may be excluded from coverage.
This type of insurance is generally considered suitable for high-value goods, sensitive or fragile products, and shipments involving substantial financial exposure.
Institute Cargo Clauses (B)
Under Institute Cargo Clauses (B), the policy identifies specific insured risks, and the insurer compensates losses arising from those risks under the contractual conditions.
Certain significant risks covered under these clauses include:
- Fire or explosion.
- Grounding, sinking, or capsizing of the vessel.
- Overturning or derailment of a land conveyance.
- Collision or contact of the vessel or conveyance with an external object.
- Earthquake, volcanic eruption, or lightning.
- Entry of seawater, lake water, or river water into the cargo storage area or conveyance, under the circumstances specified in the insurance contract.
- Sacrifice of part of the cargo as a general average measure.
Institute Cargo Clauses (C)
Institute Cargo Clauses (C) provide the most limited level of coverage among the three principal categories of Institute Cargo Clauses A, B, and C.
Under these clauses, insurance coverage applies to losses arising from a specified range of significant maritime and transportation incidents.
Some of the principal insured risks include:
- Fire or explosion.
- Grounding, stranding, or sinking of the vessel.
- Capsizing of the ship or other watercraft.
- Overturning or derailment of a land conveyance.
- Collision or contact of the conveyance with an external object.
- Emergency discharge of cargo at a port of distress, subject to the applicable conditions.
- General average sacrifice involving part of the cargo.
Total Loss Insurance
In certain insurance arrangements, Total Loss coverage is offered as a more limited form of cargo insurance.
Under this type of policy, the insurer’s liability is restricted to circumstances in which the insured goods suffer a total loss as defined in the insurance contract.
Consequently, partial damage to the cargo does not necessarily entitle the insured to insurance compensation.
When selecting this coverage, carefully examine the contractual definition of total loss and the conditions under which it is recognized.
Types of Marine Insurance Policies by Duration and Method of Issuance
Marine insurance policies may also be categorized by duration, period of validity, and the method used to define the insured transportation arrangements.
Voyage Policy
Under a Voyage Policy, insurance coverage is established for a particular voyage.
The port of origin, destination, transportation route, and specifications of the insured cargo are important elements of the contract.
For example, a company intending to transport a shipment from the Port of Shanghai to Bandar Abbas may obtain a voyage policy specifically covering that journey.
Time Policy
A Time Policy provides insurance coverage for a specified period.
Hull and Machinery Insurance and certain forms of vessel liability insurance may be issued on this basis.
Under a time policy, the commencement and expiration dates of insurance coverage are particularly important and should correspond to the vessel’s intended operating schedule.
Mixed Voyage and Time Policy
A Mixed Voyage and Time Policy combines the characteristics of voyage-based and time-based insurance.
Under this arrangement, insurance coverage may be linked to both a specified voyage and a defined period.
Open Cover
Open Cover arrangements are particularly suitable for merchants and companies that regularly ship or receive multiple consignments.
Under this arrangement, the general insurance conditions, premium rates, scope of coverage, and procedures for declaring individual shipments are agreed upon with the insurer in advance.
Each shipment is then declared and insured under the mechanism established in the agreement.
Floating Policy
A Floating Policy establishes a general framework for insuring multiple shipments, with the details of individual consignments declared subsequently in accordance with the policy conditions.
This arrangement suits companies that transport numerous shipments under similar conditions.
The main difference between Open Cover and Floating Policies lies in the contractual structure and the procedures for declaring individual shipments.
In practice, terminology and implementation methods may vary among insurance providers. Therefore, carefully examine the contractual provisions and procedures governing the issuance of insurance certificates.
What Risks Are Covered Under Marine Insurance Policies?
The specific risks covered by a marine insurance policy depend on the selected insurance clauses and the policy’s special conditions.
Common insured risks may include:
- Fire and explosion aboard a vessel or other means of transportation.
- Sinking, capsizing, or grounding of a vessel.
- Collision of a vessel with another vessel or external object.
- Cargo damage during loading and unloading operations, where coverage applies.
- Water ingress into cargo storage areas, subject to the applicable insurance conditions.
- Losses arising from certain natural disasters.
- Losses and expenses associated with general average.
- Theft, breakage, or physical damage, where the insurance contract expressly covers such risks.
Recognize that including a particular event among maritime risks does not, by itself, establish entitlement to compensation.
The insured must demonstrate that the loss is attributable to an insured risk and that the contractual requirements for indemnification have been satisfied.
What Is Commonly Excluded From Marine Insurance Coverage?
Exclusions are an important component of marine insurance policies.
Certain losses may remain outside the scope of coverage even under policies offering extensive protection.
The following exclusions should be carefully considered when reviewing a marine insurance contract.
Inherent Vice of the Goods
Where goods deteriorate, become damaged, or lose quality because of their natural properties or inherent characteristics, the resulting loss may be excluded from insurance coverage.
For example, the deterioration of perishable goods resulting from the product’s inherent nature may fall within the policy exclusions if appropriate coverage has not been obtained.
Inadequate Packaging
Where cargo is damaged because of improper or insufficient packaging, the insurer may rely on the applicable contractual conditions to deny compensation.
Packaging should match the nature of the goods, the transportation route, and the anticipated loading and handling conditions.
Delay in Transportation
Standard cargo insurance policies generally exclude losses arising solely from delays in the arrival of goods.
For example, if delayed delivery results in the loss of a commercial opportunity to sell a shipment, that financial loss may not necessarily be recoverable from the insurer.
War and Strikes
Many standard marine insurance policies exclude risks arising from war, civil unrest, strikes, and certain related disturbances.
Where coverage for such risks is required, the relevant war and strikes clauses and endorsements must be reviewed, and additional coverage may need to be arranged.
Wilful Misconduct of the Insured
Where damage results from the deliberate conduct of the insured or other persons whose actions are legally attributable to the insured, the insurer may not be obligated to provide compensation.
Frequently Asked Questions About Types of Marine Insurance Policies
Depending on the type of insurance contract, a marine insurance policy may cover loss of or damage to cargo, vessels, containers, or liabilities arising from maritime operations. The scope of the insurer's obligations depends on the policy conditions and applicable exclusions.
Clause A provides the broadest coverage, indemnifying losses arising from insured risks subject to the applicable exclusions. Clause B covers a wider range of specified risks than Clause C. At the same time, Clause C offers the most limited level of coverage among these three options.
Hull and Machinery Insurance is designed to cover loss of or damage to the vessel itself and its equipment. P&I Insurance covers specified liabilities of the shipowner or vessel operator toward third parties.
No. Certain cargo insurance policies may cover multimodal transportation involving inland, maritime, and air transport from the point of origin to the final destination. The precise scope of coverage must be specified in the insurance policy.
War risks are generally excluded from standard marine insurance policies. To obtain coverage for such risks, the relevant war risk clauses and endorsements must be examined, and additional coverage may be purchased where available.
Depending on the nature of the loss, the insurer may request the insurance policy, bill of lading, commercial invoice, packing list, survey report, delivery and unloading records, and photographic evidence of the damage.
A Voyage Policy provides insurance coverage for a specified voyage and transportation route. In contrast, a Time Policy covers the insured subject matter for a defined period.
No. Cargo insurance provides compensation for loss of or damage to insured goods in accordance with the policy terms, whereas carrier liability insurance relates to the legal or contractual liabilities of the transportation company toward the cargo owner.

What is the difference between a Voyage Policy and a Time Policy?
Is cargo insurance the same as carrier liability insurance?
Our supplier arranged the cargo insurance, but the policy is in their company’s name. Can we still claim if the goods arrive damaged?
Possibly, but it depends on who is insured and whether the policy rights have been transferred to you. The sales terms, insurance certificate, and your financial interest in the goods would need to be reviewed.
We found water damage inside our container three days after delivery. Is it too late to report it to the insurance company?
Not necessarily. However, insurance policies often require prompt notification of damage. You should preserve the packaging, photographs, and delivery records, as the insurer may need evidence of when and how the damage occurred.
Our company has an open cover policy, but we forgot to declare one shipment before it left China. Does that mean it’s uninsured?
That depends on the declaration requirements in your agreement. Some policies provide mechanisms for late declarations under certain conditions. The insurer would need to review the policy wording and circumstances before determining whether coverage applies.
The ship changed its route and transferred our cargo to another vessel. Do we need to tell the insurance company about that?
It would be advisable to notify the insurer. Certain route changes or transshipments may affect the policy conditions, particularly where they represent a material change in risk. Whether additional approval is required depends on the coverage terms.
Our machinery was worth $200,000, but we only insured it for $120,000. What happens if part of it gets damaged?
Underinsurance can affect the amount recoverable, even where the loss is only partial. Some policies apply an average clause that reduces compensation proportionately. The valuation provisions and applicable insurance rules would need to be examined.
Our cargo got damaged during unloading, but the port operator says it wasn’t their fault. Do we have to prove who’s responsible before claiming insurance?
Not always. A cargo insurance claim generally focuses on whether the damage falls within the insured risks, rather than requiring you to establish another party’s liability first. However, you still need evidence of the loss and its circumstances.
The insurance company wants us to keep all the damaged products for inspection, but they’re taking up warehouse space. Can we dispose of them?
Disposing of damaged goods without the insurer’s agreement could complicate the claim. The insurer may have inspection or salvage rights. I would recommend obtaining written instructions before selling, repairing, or disposing of the goods.
Our shipment arrived safely, but now the shipping company is asking us to pay a general average deposit. Would our cargo insurance handle that?
Many cargo policies provide coverage for qualifying general average contributions, subject to their terms. The insurer may also arrange the required security. You should notify the insurer before making payment or signing any related guarantee.
We’re importing electronics into Iran, and the foreign insurance company says international payment restrictions are delaying our claim. What can we do?
Payment restrictions can create practical and legal complications, even where the loss is covered. The insurer’s obligations, applicable sanctions, and payment provisions would need to be examined to determine what lawful options are available.
The carrier offered to pay us directly for damaged cargo. If we accept, can we still claim the remaining loss from our insurer?
Potentially, but you should inform the insurer before accepting any settlement. Insurance policies may contain subrogation provisions, and settling with the carrier could affect the insurer’s recovery rights. The settlement terms should be reviewed carefully.
