Marine Insurance: Types of Marine Insurance Policies
India’s merchandise trade crosses $700 billion annually — one of the largest trading economies in the world. Goods move constantly between Indian ports and destinations across the globe — textiles from Surat to Frankfurt, electronics from Bangalore to Dubai, pharmaceuticals from Mumbai to São Paulo, machinery from Chennai to Lagos, handicrafts from Jaipur to New York. Every container, every shipment, every consignment loaded on a vessel at JNPT, Mundra, Chennai, or any Indian port represents financial value that is exposed to a specific set of risks the moment it leaves the factory. Marine insurance is the financial protection that makes international trade possible by eliminating the catastrophic risk of losing an entire shipment. This guide is for every Indian exporter and importer who moves goods internationally and domestically.
What Marine Insurance Is and Why It Is Indispensable
Marine insurance is one of the oldest forms of insurance in the world — the concept originated in Mediterranean trading ports in the 14th century specifically to enable merchants to trade without risking total ruin if a ship sank. The fundamental problem marine insurance solves has not changed: when goods travel thousands of kilometres across oceans, through ports, and via various transport modes, the probability of some loss or damage occurring is real and the financial magnitude can be devastating.
A container ship from Mumbai to Rotterdam takes approximately 25 to 30 days at sea. During that journey, the goods are exposed to: rough seas and weather-related physical damage, fire on the vessel, vessel collision or grounding, piracy in certain high-risk routes (Gulf of Aden, for example), loading and unloading damage at ports, theft or pilferage in transit, contamination or damage from other cargo, and the catastrophic possibility of general average — where goods from all shippers on a vessel are deliberately sacrificed to save the ship, with the cost distributed proportionately among all cargo owners.
Without marine insurance, any of these events could result in complete financial loss of the shipment value. With marine insurance, the insured value is recovered regardless of the cause of loss.
Types of Marine Insurance Policies
Single Voyage Policy covers a specific consignment for a single, defined voyage — from the point of origin to the specified destination. This is the simplest form of marine insurance and is appropriate for one-off or occasional shipments. Each shipment requires a new policy to be issued with specific details of the cargo, vessel, route, and sum insured.
Open Marine Policy or Open Cover is a pre-arranged policy framework that covers all shipments made by the insured within the policy period (usually one year), automatically and without the need to issue a separate policy for each shipment. The exporter or importer declares each shipment under the open cover as it is made, and insurance automatically attaches. Open covers are the standard arrangement for regular exporters and importers who make multiple shipments throughout the year — they eliminate the administrative burden of issuing individual policies for each shipment.
Annual Policy for Inland Transit covers goods moving within India by road, rail, or air. This is relevant for domestic trade and for the inland legs of international shipments (factory to port, port to distribution centre). Inland transit insurance covers goods against fire, accident, theft, and other perils during domestic movement.
Clauses — The Core of Marine Insurance Coverage
Marine insurance coverage is defined by specific international clauses developed by the Institute of London Underwriters (ILU), now called the International Underwriting Association. Indian marine insurance policies reference these Institute Cargo Clauses as the standard terms. Understanding which clause applies to your shipment determines exactly what is and is not covered.
Institute Cargo Clauses (A) — also called All Risks clauses — provides the broadest coverage available. All physical loss or damage to the insured goods from any external cause is covered, with only a limited list of specific exclusions. This is the most comprehensive and most commonly recommended clause for valuable, fragile, or high-risk cargoes. The exclusions from ICC(A) include: wilful misconduct of the assured, ordinary leakage and natural loss in weight, inherent vice of the goods, delay, insolvency of the carrier, war and strikes (available as separate add-ons), nuclear perils, and unseaworthiness of the vessel.
Institute Cargo Clauses (B) provides intermediate coverage — a named-perils basis where only losses from a specified list of perils are covered. The covered perils include fire or explosion, vessel stranding, sinking, or capsizing, overturning of land conveyance, collision, earthquake or volcanic eruption, lightning, general average sacrifice, jettison, washing overboard, entry of sea/lake/river water, and total loss of any package overboard or dropped during loading/unloading. Compared to ICC(A), coverage is narrower and does not include theft, pilferage, or rain damage unless these result from a covered event.
Institute Cargo Clauses (C) provides the most basic and narrowest coverage — major casualty perils only. Fire or explosion, vessel stranding/sinking/capsizing, overturning of land conveyance, collision, general average sacrifice, and jettison. For most modern cargo, ICC(C) is inadequate as it misses many common causes of partial loss.
War and Strikes Clauses
War, mines, torpedoes, and similar perils of war are excluded from all three ICC clauses and covered separately under Institute War Clauses. Similarly, strikes, riots, civil commotions, and terrorism are excluded from standard ICC clauses and covered separately under Institute Strikes Clauses. For shipments through high-risk areas — routes passing through the Red Sea, Gulf of Aden, certain West African waters, or areas of active conflict — war and strikes clauses are essential additions that must be specifically requested and paid for. The additional premium for war and strikes clauses varies based on the route’s risk classification.
Valuation and Sum Insured — Getting It Right
The sum insured for marine insurance should reflect the CIF value — Cost, Insurance, Freight — which is the invoice value of the goods plus freight charges plus the insurance premium itself, plus an agreed addition of typically 10% for anticipated profit on the goods. This 10% uplift above CIF is standard and ensures that in addition to recovering the cost of the goods and their freight, the insured also recovers an approximation of the profit that would have been earned if the goods arrived safely.
Under-insurance of cargo is a mistake with significant consequences — the principle of average applies, meaning any claim settlement is reduced proportionately to the degree of underinsurance. Always insure at full CIF plus 10%.
The General Average Concept
General average is a principle unique to maritime law and one of the most misunderstood concepts in cargo insurance. General average is declared when the captain of a vessel decides to voluntarily sacrifice some cargo or incur extraordinary expenses to save the ship and its remaining cargo from a common peril. The classic example is jettisoning some containers into the sea during a storm to stabilise the ship and prevent sinking.
When general average is declared, all cargo owners on the vessel — whether or not their specific cargo was sacrificed — must contribute proportionately to the loss. A cargo owner whose goods arrived safely may still be required to pay a general average contribution (which can be 10 to 30% of cargo value) simply because they shared the vessel. Refusing to pay the general average contribution can result in the shipping line detaining the cargo at destination until payment is made.
Marine insurance covers general average contributions as a standard insured loss. Cargo owners without marine insurance who face a general average declaration can face significant out-of-pocket contributions with no coverage. This is one of the most practically important arguments for maintaining proper marine insurance even for otherwise routine shipments.
Marine Insurance for Indian Exporters — Specific Considerations
Indian exporters under CIF or CIP Incoterms (where the seller arranges insurance on behalf of the buyer) are responsible for placing marine insurance on the goods up to the destination port. Indian exporters under FOB or FCA Incoterms (where the buyer takes responsibility from the point of export) may choose to insure for the domestic inland transit from factory to port even if the ocean voyage insurance is the buyer’s responsibility.
The Exim Bank of India and ECGC (Export Credit Guarantee Corporation) are important organisations for Indian exporters beyond marine insurance. ECGC provides export credit insurance — coverage against the commercial risk of the buyer not paying (insolvency, default) and political risk of the buyer’s country (currency non-convertibility, war, government actions preventing payment). Marine insurance covers the physical goods; ECGC coverage protects the receivable. Both are often needed by active exporters.

Frequently Asked Questions
My freight forwarder says the shipping line’s cargo insurance is sufficient. Do I still need my own marine insurance? Shipping lines offer cargo insurance as an add-on service — typically at higher premiums than market rates and with terms that may not fully reflect ICC clause coverage. More importantly, the shipping line’s liability under the Hague-Visby Rules (governing most ocean freight) is capped at approximately $500 per package or $2 per kilogram of cargo — far below the actual value of most commercial shipments. For a container of textiles worth ₹50 lakh, the shipping line’s maximum liability under Hague-Visby may be only ₹1 to ₹3 lakh. Separate marine cargo insurance under ICC(A) terms is almost always both better coverage and more cost-effective than the shipping line’s add-on service.
Do I need marine insurance for goods shipped by air freight? Yes. Institute Air Cargo Clauses provide the marine insurance framework for air freight shipments. The all-risks equivalent for air freight is Air Cargo Institute Clauses (Air), which covers physical loss and damage from external causes, fire, lightning, and theft. Air freight shipments, while faster, are still exposed to physical damage during loading/unloading, theft at airports, and weather-related damage. For high-value, time-sensitive goods moved by air — electronics, pharmaceuticals, luxury goods, documents — air cargo insurance is equally important as ocean cargo insurance.
