Are Cargo and Marine Insurance the Same?

What Marine Insurance Actually Covers

Marine insurance, in its full sense, is the framework of cover that protects every commercial interest connected to a sea voyage: the ship, the cargo, the freight revenue, and the legal liabilities arising from operating a vessel. In the London market, these interests are typically placed under separate policies, each governed by its own set of clauses and conventions.

Hull and machinery (H&M) cover protects your vessel against physical loss or damage — grounding, collision, fire, and the perils listed under the Institute Hull Clauses or the International Hull Clauses. The Inchmaree clause extends that cover to latent defects in machinery and negligence of crew, which would otherwise fall outside the basic perils. Sue-and-labour provisions require you to take reasonable steps to avert or minimise a loss, and your reasonable costs in doing so are recoverable — but only if you act promptly and document expenditure carefully.

Protection and indemnity (P&I) cover sits alongside H&M and addresses third-party liabilities: collision liability beyond the H&M three-quarters running-down clause, cargo damage claims brought against you as carrier, crew injury and repatriation under MLC 2006, wreck removal, and pollution. P&I is typically provided through a mutual club rather than a conventional insurer, and the rules of the club govern how claims are handled — your entry terms matter as much as the premium call.

Freight liability cover protects the revenue you stand to lose if cargo is lost or damaged and freight becomes irrecoverable, or if you face claims under a bill of lading. Whether you are subject to Hague-Visby Rules, the Hamburg Rules, or the Rotterdam Rules depends on your trading routes and the governing law of your contracts of carriage — each regime sets different liability limits and burden-of-proof rules, and your cover should be structured to match.

What Cargo Insurance Covers — and Who Needs It

Cargo insurance protects the owner of the goods against physical loss or damage during transit. It is the cargo owner's policy, not the carrier's. If you are a freight forwarder, importer, exporter, or trading company, your interest in the goods is not protected by the shipowner's H&M or P&I policy — those policies protect the shipowner's interests, and any recovery you might obtain from the carrier is capped by the applicable carriage convention and the carrier's P&I limits.

The Institute Cargo Clauses set the standard terms in the London market. Institute Cargo Clauses (A) provide the broadest cover — all risks of physical loss or damage subject to named exclusions. Institute Cargo Clauses (B) and (C) are named-perils policies covering progressively narrower lists of events. For most general cargo, Clauses (A) is the appropriate starting point; for bulk commodities or lower-value shipments, (B) or (C) may be commercially justified, but you should understand precisely what you are giving up.

General average is the mechanism by which all parties to a common maritime adventure — shipowner, cargo owners, freight interests — share in losses and expenditure incurred to save the voyage. Under the York-Antwerp Rules (the version incorporated into your bill of lading governs), if the master declares general average, your cargo may be detained until you provide a general average bond and, usually, a cash deposit or insurer's guarantee. Without cargo insurance, you fund that deposit from your own balance sheet. With it, your insurer provides the guarantee and handles the average adjuster's process on your behalf.

Cargo insurance also responds to sue-and-labour costs you incur to protect the goods — repackaging damaged cargo at a transhipment port, hiring security to guard a container held at a terminal, or arranging emergency forwarding. These costs are recoverable under a properly worded policy, but only if the policy is in place before the loss event.

Where the Two Policies Overlap — and Where They Do Not

The most common misunderstanding is that a shipowner's policy protects cargo interests. It does not. The P&I club will respond to cargo damage claims brought against the shipowner as carrier, but the recovery available to the cargo claimant is limited by the applicable carriage convention and the carrier's liability limits under the LLMC (Convention on Limitation of Liability for Maritime Claims). If your cargo loss exceeds those limits — and for high-value or bulk shipments it frequently does — the shortfall is unrecovered unless you hold your own cargo policy.

Conversely, a cargo policy does not protect the vessel. If you are a vessel operator carrying your own goods, you need both an H&M policy and a cargo policy — one for the ship, one for the freight. They are placed separately, often with different underwriters, and the claims processes are distinct.

There is a narrow area of genuine overlap in the context of freight liability. If you operate as a freight forwarder and issue your own house bills of lading, you are acting as a contractual carrier and your liability to cargo owners is not covered by a standard cargo policy. You need freight forwarder's liability or NVOCC liability cover for that exposure. Many forwarders carry cargo insurance on shipments they own or have a financial interest in, and separately carry liability cover for claims arising from their contractual obligations — the two policies serve different purposes and should not be conflated.

• H&M policy: covers the vessel against physical loss and damage; does not cover cargo interests
• P&I entry: covers the shipowner's third-party liabilities including cargo claims brought against the carrier; recovery is capped by convention limits
• Cargo policy (ICC A/B/C): covers the cargo owner's interest in the goods; does not protect the vessel or the carrier's liability
• Freight liability / NVOCC cover: covers the forwarder or NVOCC acting as contractual carrier against cargo claims under their own bills of lading
• General average: all interests exposed; cargo insurance provides the bond and deposit mechanism so your goods are released without a cash call

Choosing the Right Clauses for Your Trade

The choice between Institute Cargo Clauses (A), (B), and (C) should be driven by the nature of your cargo, your trading routes, and the terms of your sale contracts. If you are selling on CIF or CIP Incoterms, you are contractually obliged to provide cargo insurance — and under Incoterms 2020, CIP requires cover equivalent to ICC (A) as a minimum. If you are buying on FOB or CFR, the insurance obligation falls to you from the moment risk passes, which under those terms is at the ship's rail or on board at the port of loading.

War and strikes cover is excluded from the standard ICC clauses and must be added separately under the Institute War Clauses (Cargo) and Institute Strikes Clauses (Cargo). For shipments transiting areas currently listed under the Joint Cargo Committee's listed areas — including parts of the Red Sea, Gulf of Aden, and certain West African waters — war cover is not automatic and may require specific underwriter agreement. If your supply chain runs through any of these areas, confirm with us before the goods are loaded, not after.

For containerised cargo moving through major transhipment hubs — Felixstowe, Rotterdam, Hamburg, Singapore — the risk of theft, misdelivery, and damage during handling is material. ICC (A) responds to these perils; ICC (C) does not cover theft at all. If your goods are high-value, branded, or easily resaleable, the premium differential between (A) and (C) is rarely worth the coverage gap.

What to Bring When You Place or Renew

Whether you are placing cargo cover for a single shipment, an open cover for annual turnover, or a combined marine programme for a fleet with owned cargo, the quality of information you provide at placement determines the quality of the terms you receive. Underwriters price on the basis of commodity, packaging, stowage, routing, and loss history — gaps in that information produce either loaded premiums or restrictive conditions.

For an open cargo cover, your broker should be asking the underwriter on your behalf to confirm: the basis of valuation (invoice value plus agreed percentage for profit and charges), the automatic reinstatement provisions after a loss, the accumulation limit at any one location or vessel, and the survey requirements for claims above a specified threshold. These are not standard across all wordings and should be negotiated at inception, not discovered at claim stage.

For hull and P&I placement or renewal, bring your vessel's current class certificate, trading area, crew list with certificates, and a five-year claims history. If your vessel has been out of class for any period, disclose it — cover placed without disclosure of a classification lapse is voidable, and the consequences of a void policy at the time of a major casualty are severe.

• Cargo placement: commodity description, packaging, annual turnover or per-shipment value, Incoterms, routing including transhipment points, loss history for three years
• Hull placement: vessel particulars, class society and current status, trading limits, crew certificates, five-year claims history
• P&I / freight liability: trading pattern, bill of lading terms, cargo types carried, any known claims or notifications
• Open cover renewal: actual turnover vs declared estimate, any new commodities or routes added during the year, outstanding claims

Acting Promptly: When Cover Decisions Cannot Wait

Cargo insurance must be in place before the goods are at risk — not after the vessel has sailed, not after the container has been loaded. An open cover with automatic attachment provisions protects you for shipments that commence before you have time to declare each one individually, but only if the open cover is correctly structured and the goods fall within its scope. If you are placing one-off shipments, bind cover before loading.

On the hull and P&I side, a vessel trading without current class or with an expired P&I entry is not merely uninsured — it may be detained by port state control, and any cargo claims arising during that period fall entirely on the owner. The cost of maintaining continuous cover is always less than the cost of a single uninsured casualty.

If a general average is declared on a voyage carrying your cargo, contact your broker immediately. The average adjuster will require a general average bond from each cargo interest, and your insurer needs to be notified promptly to provide the necessary security. Delay in notifying your insurer can result in your goods being sold to satisfy the general average contribution — a recoverable loss that becomes an unrecovered one through inaction.

Frequently asked questions

Do I need cargo insurance if the carrier has P&I cover?

Yes. The carrier's P&I cover responds to claims brought against the carrier, but recovery is capped by the applicable carriage convention — Hague-Visby, Hamburg, or Rotterdam Rules depending on your bill of lading. For high-value or bulk cargo, those limits are frequently lower than your actual loss. Your own cargo policy under ICC (A), (B), or (C) covers your full insurable interest in the goods, not just what you can recover from the carrier.

What happens if a general average is declared and I have no cargo insurance?

The average adjuster will require a general average bond and, in most cases, a cash deposit or security before your cargo is released. Without an insurer to provide that security, you must fund it from your own resources — and the deposit can be a substantial proportion of the cargo value. Your cargo insurer provides the bond and manages the adjustment process on your behalf, which is one of the most practical reasons to hold cover even on lower-value shipments.

I am a freight forwarder issuing house bills of lading. Is my liability to cargo owners covered under a cargo policy?

No. A cargo policy covers your financial interest in goods you own or have a financial stake in. Your liability to cargo owners under your own house bills of lading is a separate exposure requiring freight forwarder's liability or NVOCC liability cover. Many forwarders need both: cargo insurance for shipments where they hold the financial interest, and liability cover for their contractual obligations as a contractual carrier.

What is the difference between ICC (A), (B), and (C) in practice?

ICC (A) is all-risks cover — it responds to any physical loss or damage not specifically excluded. ICC (B) and (C) are named-perils policies. ICC (C) covers only major casualties: fire, explosion, vessel stranding, grounding, sinking, capsizing, collision, and discharge at a port of distress. Theft, contamination, leakage, and damage during handling are not covered under ICC (C). For most general cargo, ICC (A) is the appropriate baseline; the choice of (B) or (C) should be a deliberate commercial decision, not a default.

Does my cargo policy cover war risks on Red Sea or Gulf of Aden transits?

Not automatically. War and strikes cover is excluded from the standard ICC clauses and attached separately under the Institute War Clauses (Cargo) and Institute Strikes Clauses (Cargo). Areas listed by the Joint Cargo Committee — which currently include parts of the Red Sea and Gulf of Aden — require specific underwriter agreement and may attract additional premium. Confirm your war cover is in place and correctly endorsed before goods are shipped through any listed area.

How quickly can cargo cover be bound for a shipment that is loading shortly?

For a single shipment under a new policy, binding typically takes one to two working days once we have the full cargo details, routing, and valuation. If you hold an open cover with automatic attachment, shipments within scope attach immediately on commencement of transit without individual binding. If you have a time-sensitive shipment, contact us as early as possible — cover cannot be backdated to attach before the goods were at risk.
