Marine Insurance.

The Risk Backbone of Every Consignment in Transit.

Published as on 22 July 2026

Marine insurance indemnifies goods, cargo, vessels and freight against physical loss or damage while they move — by sea, air, road or rail. Despite the name, it is not only for shipowners: the importer buying from China, the pharma company trucking medicines across states, the exporter shipping to Europe all carry marine exposure the moment goods leave the door. Governed by the Marine Insurance Act, 1963 and regulated by IRDAI, it is the oldest and most commercially important branch of general insurance in India. Standard Institute Cargo Clauses (ICC A/B/C) and Inland Transit Clauses set the width of cover; the market convention is to insure at CIF value + 10% for imports and invoice value + 10% domestically. For a business the premium is a deductible expense, with 18% GST generally reclaimable as input tax credit.

Executive Summary · 6 Findings

Every time goods move, they are exposed — fire on a vessel, a highway accident, theft at a container yard, water in the hold. Marine insurance transfers that risk to an insurer so a mid-journey disaster does not become an unrecoverable loss on the balance sheet. It answers one question for a trader: if this consignment never arrives intact, who absorbs the hit? The catch is precision — the cover only responds to what the clause covers, insured to the value you declared, subject to exclusions like delay and inherent vice.

Covers what marine insurance is and why it matters beyond shipping companies, its legal foundation in the Marine Insurance Act 1963 and the five governing principles, the five product types (cargo, hull, inland transit, marine liability, freight) and three policy structures, the ICC and ITC coverage clauses and the standard exclusions, the tax position under Sections 36(1)(i) and 37(1) with 18% GST input credit, the six-step claim process, and six questions Indian businesses ask.

Key Findings

It covers far more than ocean shipping.

Marine insurance indemnifies physical loss or damage to goods, cargo, ships and freight in transit by sea, air, road or rail — domestic or international. The "marine" label is a legal legacy: inland transit within India, entirely by truck or train, falls squarely under it. Any business that buys, sells or moves physical goods has exposure.

The Marine Insurance Act, 1963 sets the rules.

Modelled on the British Act of 1906 and in force since 1st August 1963, it codifies insurable interest, indemnity, utmost good faith, subrogation and contribution. IRDAI regulates the class but has not standardised it into one product; internationally recognised ICC and ITC clauses supply the common coverage framework.

Five types, three structures — match them to the risk.

Cargo, hull, inland transit, marine liability (P&I) and freight are the five product types. Structures range from a single voyage policy to an annual open cover that insures all shipments automatically, to a sales turnover policy priced on total turnover. Regular shippers use open cover to avoid ever leaving a consignment uninsured.

Insure at value + 10%, and mind the exclusions.

Market convention is CIF value + 10% for imports and invoice value + 10% domestically; the extra 10% is anticipated profit. As a contract of indemnity, under-insurance means you share the loss. Standard clauses exclude delay, inherent vice, poor packing, wilful misconduct, war and strikes, and all consequential loss of market.

The premium is a business expense, not an 80C/80D deduction.

For a business, premium on stock-in-trade is deductible under Section 36(1)(i); premium on other assets under Section 37(1) — both available under old and new regimes. An 18% GST applies and is generally claimable as input tax credit where the cover relates to taxable activity. This is commercial risk transfer, not a personal tax-saving product.

On a loss, claim from your insurer — not the carrier.

Notify immediately, file written notice on the carrier to preserve subrogation rights, retain the damaged goods for the surveyor, and assemble the documents. Carrier liability is capped and slow; claiming from your marine insurer is faster and more certain. Let the insurer pursue the negligent carrier through subrogation afterwards.

The Opening · Page 3

The Opening

Marine insurance is the oldest form of commercial cover, and it exists for a blunt reason: goods in motion are goods at risk. A consignment on a highway, a container on a vessel, a pallet in an aircraft hold — each is exposed to fire, collision, sinking, theft and water damage the moment it leaves the warehouse. Without insurance, any one of those events destroys the economic value of the shipment and lands, unrecovered, on the owner. Marine insurance bridges that gap: it pays for physical loss or damage in transit, so commerce continues even when disaster strikes mid-journey.

"Marine insurance does not stop the crate from breaking or the ship from sinking. It ensures that when they do, the loss lands on an insurer's books and not on a business that simply moved its goods from one place to another."
Risk Transfer, Not Risk Removal

Beyond shipping companies. It is a common error to think marine insurance is only for shipowners and freight forwarders. The importer buying from China, the pharma company moving medicines from a Himachal plant to distributors nationwide, the apparel exporter shipping to Europe, the distributor receiving stock from a manufacturer — all carry marine exposure. An uninsured consignment damaged in transit is a direct, unrecoverable loss.

Precision is everything. Marine insurance is not a blanket. It responds only to what the chosen clause covers — all-risks under ICC-A, or a short named-perils list under ICC-C — up to the value you declared, and subject to firm exclusions like delay, inherent vice and poor packing. Getting the clause, the sum insured and the Incoterms right is what separates a paid claim from a rejected one.

The Honest Boundary: Marine insurance is NOT a personal tax-saving product — the premium is a business expense, never an 80C/80D deduction. It is NOT a guarantee against delay or lost profit — only physical loss or damage is indemnified. It is NOT one-size-fits-all — the coverage you get is exactly the clause you bought. It IS the essential risk backbone of any business that moves physical goods, provided the cover is scoped and valued correctly.

What Marine Insurance Is, the Act That Governs It, and the Five Principles

Why goods-in-transit risk sits at the heart of commerce; how the Marine Insurance Act, 1963 codifies the contract; and the five principles — insurable interest, indemnity, utmost good faith, subrogation and contribution — that decide when and how a claim is paid.

Part I · Page 4

The Legal Foundation

Marine Insurance Act, 1963

In force since 1st August 1963 and closely modelled on the British Marine Insurance Act of 1906, it codifies the fundamental rules of every marine contract in India — what an insurable interest is, how loss is measured, when the insurer is liable, and the duties of the insured. It has seen no significant amendment and remains the governing statute in FY 2025-26.

IRDAI Oversight — but No Single Product

IRDAI regulates marine cover as part of general insurance — approving wordings and monitoring settlements — but, unlike home cover (Bharat Griha Raksha), it has not standardised marine into one mandatory product. Insurers offer varying terms, and the internationally recognised Institute Cargo Clauses (ICC) and Inland Transit Clauses (ITC) provide the common framework used across the market.

Because there is no single standardised policy, the burden is on the buyer to read the clause. Two policies both labelled "marine cargo" can differ enormously in what they actually pay for — which is why the ICC/ITC lettering matters more than the product name.

The Five Governing Principles

Principle	What It Means
Insurable interest	A genuine financial stake, existing at the time of loss
Indemnity	Recover actual loss, no profit from a claim
Utmost good faith	Disclose all material facts honestly
Subrogation	Insurer inherits your recovery rights vs third parties
Contribution	Multiple insurers share proportionately

Insurable interest must exist when the loss occurs, not merely when the policy is bought — decisive under Incoterms, where an FOB seller's interest ends the moment goods are loaded. Indemnity caps recovery at your actual loss, which is why the CIF/invoice + 10% convention exists to capture lost profit.

Why the principles bite: Non-disclosure of a material fact — the true nature of the goods, the route, the packing — can void the contract under utmost good faith, even if unintentional. And because subrogation transfers your right to sue a negligent carrier to the insurer, you cannot double-collect: claim from the insurer and let them chase the carrier.

Part II

The Five Product Types and the Three Ways to Structure the Cover

Cargo, hull, inland transit, marine liability and freight — what each protects and who needs it; and whether to buy a single voyage policy, an annual open cover that insures every shipment automatically, or a sales-turnover policy priced on the whole year's trade.

Part II · Page 6

The Five Types

Type	What It Covers	Who Needs It
Cargo	Goods in transit	Importers, exporters, traders
Hull	The vessel & machinery	Shipowners, operators
Inland transit	Road/rail goods in India	Almost every mover of goods
Liability (P&I)	Third-party legal liability	Shipping operators
Freight	Lost freight charges	Carriers, logistics firms

Inland Transit — the Everyday Workhorse

Despite the "marine" name, inland transit insurance has nothing to do with the sea. It protects goods moving entirely within India by truck or train — factory to warehouse, supplier to retailer. Insurance law has always treated goods-in-transit as marine risk, so it is governed by the 1963 Act. It is the most common form for domestic businesses, and the one that surprises first-time buyers most.

Hull covers the ship's body, engines and machinery against perils of the sea; it excludes loss of hire, war and ordinary wear. P&I (Protection & Indemnity) covers a shipowner's liability to third parties and is usually arranged through mutual P&I Clubs — not relevant for land-based businesses.

The Three Structures

Voyage / Trip Policy

A single policy for one consignment on one journey; a fresh policy for every shipment. Best for infrequent, one-off movements — a manufacturer importing a machine for a specific project, or an occasional overseas purchase.

Open Policy (Marine Open Cover)

An annual arrangement that covers all shipments automatically on pre-agreed terms. You declare shipments periodically and pay on the accumulated declared value. Its key advantage: no consignment is ever accidentally left uninsured because a voyage policy was not bought in time. Ideal for regular importers, exporters and distributors.

Sales Turnover Policy

An IRDAI-approved open-policy variant where premium is calculated on total sales turnover rather than individual shipment values. An advance premium is paid on estimated turnover and adjusted against actuals at year-end. Best for high-volume shippers of many small consignments — FMCG, pharma distribution.

The Certificate of Insurance

Under an Open Policy

Each consignment under an open cover gets its own Certificate of Insurance — a negotiable document confirming that specific shipment is covered. Banks require it for documentary-credit (LC) transactions, and it can be endorsed and transferred along with ownership of the goods.

Part III

The Coverage Clauses, What Is Never Covered, and How the Premium Is Taxed

ICC A/B/C for international shipments and ITC for domestic ones; the standard exclusions — delay, inherent vice, poor packing, war and strikes, loss of market — that survive every policy; and why the premium is a Section 36(1)(i)/37(1) business expense with 18% GST input credit, not a personal deduction.

Part III · Page 8

The Coverage Clauses

Clause	Scope	Use
ICC-A	All risks	Most importers/exporters
ICC-B	Named perils (medium)	Selective, cost-sensitive
ICC-C	Named perils (basic)	Major casualties only
ITC-A	All risks (ex-rainwater)	Most domestic cargo
ITC-B	Accidental damage only	Narrow domestic cover

ICC-A indemnifies all physical loss or damage except specific exclusions — the widest cover and the safe default. ICC-B adds events like earthquake, jettison, washing overboard and water ingress to major casualties; ICC-C covers only fire, explosion, stranding, sinking, capsizing and collision. Domestically, ITC-A mirrors all-risks (bar rainwater), ITC-B only accidental damage. Theft is included under all-risks wordings but not under named perils.

War & Strikes — Always Extra

Standard ICC and ITC clauses exclude war and losses from strikes, riots and civil commotion. Businesses exposed to conflict-prone regions or labour-disrupted ports buy separate Institute War Clauses and Institute Strikes Clauses as add-ons.

What Is Never Covered

Standard Exclusions

Delay — loss from late arrival, even via an insured peril. Inherent vice — natural rust, decay, evaporation, fermentation. Inadequate packing. Wilful misconduct of the insured. War & strikes (add-on only). NBC weapons. Consequential loss / loss of market — a missed sales window is not covered. Only physical loss or damage to the goods is indemnified.

The Tax Position (FY 2025-26)

A Business Expense, Not 80C/80D

Premium to insure stock-in-trade in transit is explicitly deductible under Section 36(1)(i); premium on other business assets — vessels, machinery, freight — is deductible as ordinary business expenditure under Section 37(1). Both apply to business income under the old and new regimes, unaffected by the new regime's limits on personal Chapter VI-A deductions.

18% GST → Input Tax Credit

An 18% GST applies on the premium. A GST-registered business can generally claim it as input tax credit where the cover relates to taxable business activity — marine cargo insurance is not a blocked credit under Section 17(5) of the CGST Act. Confirm eligibility for your specific circumstances with a GST advisor.

Part IV

The Verdict

Cover the goods for what they are worth. Then claim it the right way.

Part IV: The Verdict · Page 10

30-Second Summary

Marine insurance indemnifies physical loss or damage to goods, cargo, ships and freight in transit — by sea, air, road or rail. Governed by the Marine Insurance Act, 1963 and regulated by IRDAI, it spans five product types (cargo, hull, inland transit, liability, freight) and three structures (voyage, open cover, sales turnover). ICC A/B/C and ITC clauses set the width of cover; the market convention is CIF/invoice value + 10%. Standard exclusions — delay, inherent vice, poor packing, war and strikes, loss of market — apply across the board.

For a business the premium is a deductible expense (Section 36(1)(i) for stock, Section 37(1) for other assets), with 18% GST generally claimable as input tax credit — never a personal 80C/80D benefit. On a loss, notify at once, file written notice on the carrier to protect subrogation, retain the goods for the surveyor, and claim from your insurer rather than chasing the carrier's capped liability. Get the clause, the sum insured and the Incoterms right, and marine insurance does exactly what it should.

"A marine policy is only as good as the clause you chose and the value you declared. Insure the goods for what they are truly worth — cost plus freight plus the profit you would lose — pick all-risks unless you have a reason not to, and when something goes wrong, claim from the insurer and let them chase the carrier. That is the whole discipline."
The Final Orientation

The Bottom Line: Any business that moves physical goods needs marine cover — and regular shippers should hold an open cover so no consignment is ever left uninsured. Insure at CIF/invoice value + 10%, choose ICC-A / ITC-A unless cost forces a narrower clause, and add war and strikes cover for exposed routes. Nail down who insures under the Incoterms. Treat the premium as a deductible business expense and reclaim the 18% GST where eligible. On a claim, act fast, preserve carrier-notice and subrogation rights, and keep the damaged goods for the surveyor. Read the clause, not the product name.

ADWIZR · July 2026

The Claim Process

Notify immediately.

Report the loss or damage to your insurer the moment you discover it. Do not wait.

Preserve rights against the carrier.

Issue formal written notice of loss to the shipping line, airline, railway or transporter on delivery — this protects subrogation. File within the Bill of Lading's time limit.

Do not dispose of damaged goods.

Retain damaged goods, broken packaging and containers until the surveyor inspects. Premature disposal can void the claim.

Gather documentation.

Policy/open-cover certificate, Bill of Lading or Airway Bill or Lorry Receipt, invoice and packing list, survey report, photographs, and carrier correspondence.

Surveyor assessment.

A licensed marine surveyor examines the goods and assesses the cause and extent of loss.

Settlement.

Indemnity on actual loss — repair cost for partial, replacement for total — subject to sum insured, deductibles and exclusions.

Business FAQ

Questions Indian Businesses Ask

Six questions, answered directly.

Business FAQ · Page 12

Frequently Asked Questions

Q1 Does marine insurance cover domestic road and rail transport within India?

Yes. Inland Transit Insurance, written under the Inland Transit Clauses (ITC), covers goods moving entirely within India by road truck or railway — factory to warehouse, city to city, supplier to retailer. Insurance law has historically treated all goods-in-transit as marine risk, so this cover is governed by the Marine Insurance Act, 1963. Neither the goods nor your business needs any connection to the sea; the word "marine" is a legal legacy that surprises most first-time buyers.

Q2 Who insures the goods — the buyer or the seller?

It depends on the Incoterms agreed. Under CIF or CIP terms the seller arranges and pays for insurance; under FOB or EXW terms the buyer carries the risk from the point of loading. Because insurable interest must exist at the time of loss, an FOB seller's cover ends when the goods are loaded and the buyer must insure onward. For domestic deals, agree in writing who carries the transit risk — ambiguity is a common source of disputes when damage occurs.

Q3 How much should I insure my cargo for?

The established market convention is CIF (Cost + Insurance + Freight) value + 10% for international imports, and invoice value + 10% for domestic and export shipments. The extra 10% represents anticipated profit — the margin you lose if the consignment is destroyed before it reaches you — and insurers specifically permit this loading. Insure below the true value and, because marine insurance is a contract of indemnity, you bear a proportionate share of any loss yourself.

Q4 Is the premium tax-deductible, and can I claim GST input credit?

For a business, yes. Premium to insure stock-in-trade in transit is explicitly deductible under Section 36(1)(i) of the Income Tax Act, 1961; premium on other business assets such as vessels, machinery or freight is deductible under Section 37(1). Both apply to business income under the old and new regimes, and are unaffected by the new regime's limits on personal 80C/80D deductions. An 18% GST applies and a GST-registered business can generally claim it as input tax credit where the cover relates to taxable activity. It is a commercial expense, not a personal tax-saving deduction.

Q5 What is the difference between ICC-A, ICC-B and ICC-C clauses?

The Institute Cargo Clauses set the coverage width for international shipments. ICC-A is "all risks" — the widest cover, indemnifying all physical loss or damage except specific exclusions, and recommended for most importers and exporters. ICC-B is a named-perils cover for major casualties plus events like earthquake, jettison, washing overboard and water ingress. ICC-C is narrowest, covering only major vessel casualties — fire, explosion, stranding, sinking, collision. Theft is generally covered under ICC-A but not ICC-B or ICC-C. Domestic shipments use the parallel ITC-A and ITC-B clauses.

Q6 Does marine insurance cover theft, delay and lost profits?

Theft is generally covered under all-risks wordings (ICC-A or ITC-A) but not under named-perils clauses (ICC-B, ICC-C, ITC-B). Delay is excluded across the board — even loss caused by an insured peril that merely delays the goods is not payable. Consequential losses, such as a missed sales window or a lost market when goods arrive late, are also excluded; marine insurance indemnifies physical loss or damage to the goods themselves, not the commercial opportunity around them. War and strikes are excluded from standard clauses and need separate add-on cover.

Key Terms & Definitions

Institute Cargo Clauses (ICC)

Standard internationally recognised clauses defining the width of marine cargo cover for international shipments. ICC-A is all-risks; ICC-B and ICC-C are progressively narrower named-perils covers. The lettering, not the product name, tells you what is actually protected.

Inland Transit Clauses (ITC)

The domestic equivalent of the ICC, governing goods moving within India by road or rail. ITC-A is broad all-risks cover (excluding rainwater damage); ITC-B covers only accidental damage. Governed, despite the "marine" label, by the Marine Insurance Act, 1963.

Insurable Interest

A genuine financial stake in the insured property, such that you would suffer a real monetary loss if it were damaged or lost. It must exist at the time of loss, not merely when the policy is bought — decisive in Incoterms-based trade.

Indemnity

The principle that a claim restores your actual financial loss and no more — you cannot profit from insurance. It underpins the CIF/invoice + 10% convention, which captures the anticipated profit that would otherwise fall outside a pure cost-based indemnity.

Subrogation

After paying your claim, the insurer inherits your right to recover the amount from any third party responsible — typically a negligent carrier. You cannot double-collect: your recovery right transfers to the insurer once you are indemnified.

General Average

An ancient maritime principle: when part of a cargo or the vessel is deliberately sacrificed to save the whole venture (say, jettisoning goods in a storm), all parties with an interest share the loss proportionately. Marine policies typically cover the insured's general average contribution.
