Cargo Damaged in Transit — What Your Insurance Should Pay For

Which Institute Cargo Clauses You Hold Changes Everything

The Institute Cargo Clauses (ICC) are the foundation of almost every marine cargo policy placed in the London market. There are three sets — A, B, and C — and they are not interchangeable. ICC (A) is the broadest, covering all risks of physical loss or damage except a defined list of exclusions. ICC (B) and ICC (C) are named-perils covers: if the cause of damage is not on the list, the claim does not respond. Most cargo owners assume they have 'all risks' cover; many discover on a claim that they placed ICC (C) because it was cheaper at renewal.

ICC (A) will respond to wetting, contamination, theft, breakage, and most accidental physical damage during the voyage. ICC (B) adds earthquake, volcanic eruption, and washing overboard to the ICC (C) perils of fire, explosion, stranding, sinking, collision, and discharge at a port of distress. If your cargo is containerised general freight moving on a liner service, ICC (A) is the standard you should insist on. If your broker is quoting ICC (B) or (C) without explaining the trade-off, ask why.

Exclusions apply across all three sets. Inherent vice — the natural tendency of a cargo to deteriorate — is excluded under every clause. Inadequate packing is excluded. Delay is excluded, even when the delay is caused by an insured peril. War and strikes are excluded from the base clauses but can be reinstated by endorsement under the Institute War Clauses (Cargo) and Institute Strikes Clauses (Cargo). If your trade lane passes through areas listed under the Joint Cargo Committee's current designated war zones, those endorsements are not optional.

What the Policy Should Pay — and the Valuation Trap

A marine cargo policy pays the insured value of the goods, not the market value at destination and not the replacement cost unless you have specifically agreed an agreed-value basis with the underwriter. The standard London-market approach is to insure CIF (cost, insurance, freight) plus a percentage uplift — typically described in your policy as the 'insured value' — to account for anticipated profit. If you insure at invoice value only and your goods appreciate in transit, you will be underinsured at the point of claim.

Total loss is straightforward: the underwriter pays the insured value. Partial loss is where disputes arise. The measure of indemnity for a partial loss under English law (Marine Insurance Act 1906) is the proportion that the damaged value bears to the sound arrived value, applied to the insured value. That calculation can produce a payment materially different from what you spent on repairs or what your buyer deducted from your invoice. Your surveyor's report needs to capture both the sound and damaged values at destination, not just the cost of remediation.

General average is a separate exposure that catches many cargo owners off guard. If the vessel's master declares general average under the York-Antwerp Rules — most commonly after a fire, grounding, or container loss overboard — every cargo interest is required to contribute to the shared sacrifice proportionally. Your cargo policy should include a general average clause that pays your contribution and advances the general average deposit so your goods are not held at the discharge port while the adjustment runs. Check your policy wording: some open covers exclude general average on shipments below a minimum value.

Sue and Labour, Forwarding Charges, and What Happens at the Port of Refuge

The sue-and-labour clause in your policy is not just a procedural formality. It obliges you to take reasonable steps to minimise loss after an insured peril occurs, and it entitles you to recover the reasonable costs of doing so from your underwriter — even if those costs exceed the value of the cargo saved. If your container is discharged at a port of refuge following a casualty, the costs of re-stuffing, fumigation, onward freight, and storage can dwarf the original freight cost. A policy that includes forwarding charges cover will pick up those expenses; one that does not will leave them with you.

Notify your underwriter or their appointed average agent as soon as you become aware of a casualty or suspected damage. Failure to give prompt notice is one of the most common reasons underwriters reserve their position on a claim. Under the Insurance Act 2015 (which governs most London-market placements), your duty is one of fair presentation — but that duty runs at inception, not just at claim. If your cargo description, packing method, or stowage arrangements were not accurately presented when the policy was placed, the underwriter has remedies that can reduce or void the claim payment.

Freight Liability, Carrier Defences, and Why Your Cargo Cover Is Not the Carrier's Problem

One of the most persistent misunderstandings in cargo claims is the assumption that if the carrier damaged your goods, the carrier pays. In practice, carriers operating under bills of lading governed by the Hague-Visby Rules — which apply to most UK and EEA international shipments by statute — benefit from package and unit limitation of liability. That limit is expressed in Special Drawing Rights and is almost always a fraction of the commercial value of a modern containerised shipment. The Hamburg Rules and Rotterdam Rules offer different liability frameworks, but Hague-Visby remains the operative convention on most trades your cargo will move on.

Your cargo policy responds first and then your underwriter pursues the carrier by subrogation. That is the correct commercial sequence. What it means for you is that your policy needs to be in place and properly structured before the shipment moves — not arranged after the damage is discovered. It also means you must preserve your rights against the carrier: note damage on the delivery receipt, issue a formal reservation of rights within the time limits in the bill of lading (typically three days for non-apparent damage under Hague-Visby), and do not settle or release the carrier without your underwriter's consent.

If you are a freight forwarder operating under your own house bills of lading, your exposure is different. You are the carrier of record to your shipper, and your liability to them is not capped by your own cargo policy — it is governed by your freight liability or freight forwarder's liability cover, which is a separate placement. Conflating the two is a structuring error that leaves a gap in your protection.

Making the Claim — What to Prepare and What to Expect

A cargo damaged in transit insurance claim in the London market moves faster when you arrive with the right documentation. Underwriters and their appointed surveyors will expect to see the commercial invoice and packing list, the bill of lading or sea waybill, the survey or outturn report, photographs of the damage in context (not just close-ups), the carrier's delivery receipt with any damage notation, and your formal claim against the carrier. Missing documents do not kill a claim, but they slow it and give the underwriter grounds to request further information before agreeing quantum.

Appoint a surveyor at the port of discharge before the cargo is moved or repaired. This is not optional — it is a condition of most policies and a practical necessity. An independent survey report from a recognised average adjuster or cargo surveyor carries weight with the underwriter and protects you if the carrier disputes the cause or extent of damage. We can recommend surveyors at UK and EEA ports and at major transhipment hubs if you need a referral.

Expect the underwriter to ask about packing and stowage, particularly for fragile, temperature-sensitive, or high-value cargo. If the damage is consistent with inadequate packing, the underwriter will investigate that exclusion. Your response should be supported by evidence — packing specifications, third-party packing certificates, or pre-shipment inspection reports. If you are shipping regularly, building that documentation into your standard operating procedure costs very little and protects every future claim.

• Commercial invoice and packing list
• Bill of lading or sea waybill (original or copy as applicable)
• Survey or outturn report from an independent surveyor
• Photographs of damage taken before cargo is moved or repaired
• Carrier's delivery receipt with damage notation
• Formal written claim or reservation of rights issued to the carrier
• Packing specifications or third-party packing certificate if available

Structuring Your Cover Before the Next Shipment Moves

An open cover or floating policy is the right structure for any cargo owner or freight forwarder moving regular volumes. It binds cover automatically on each shipment within agreed parameters — commodity, packing, vessel type, trade lane — without requiring a separate placement each time. The declaration process keeps your underwriter informed and your premium accurate. A single-voyage policy is appropriate for one-off or unusual shipments, but relying on it for a regular trade programme creates gaps and administrative risk.

Your sum insured should reflect the full CIF value of each shipment plus your agreed uplift. If your commodity prices are volatile, build a review trigger into your open cover so the limit of liability per bottom and per location keeps pace with your actual exposure. Underinsurance at claim time is not a technicality — under the Marine Insurance Act 1906, the underwriter is only liable for that proportion of the loss that the insured value bears to the true value.

War and strikes cover, refrigeration breakdown endorsements for temperature-controlled cargo, and inland transit extensions for the pre-shipment and post-discharge legs are the most commonly omitted elements on policies we review when a client comes to us after a claim. Bring your current policy wording and your last three years of shipment data to your first conversation with us. We will identify the gaps before they cost you.

Frequently asked questions

Do I need a separate war risks endorsement for my cargo moving through the Red Sea or Gulf of Aden?

Yes. The base Institute Cargo Clauses exclude war risks. The Joint Cargo Committee publishes a list of designated areas where additional war risks premium applies, and Bab-el-Mandeb and the Gulf of Aden are currently on that list. If your cargo moves on a vessel transiting those waters without a war risks endorsement in place, you have no cover for loss or damage caused by a war peril. We can arrange Institute War Clauses (Cargo) cover as part of your open cover or on a voyage basis — but it must be in place before the vessel enters the listed area, not after.

What happens if the carrier says the damage was caused by inherent vice and refuses to pay?

Inherent vice is excluded under all three sets of Institute Cargo Clauses, so if the underwriter agrees with the carrier's assessment, your policy will not respond either. The key is to have an independent survey report that establishes the actual cause of damage — external impact, wetting, temperature excursion — rather than accepting the carrier's characterisation. A well-documented survey report from a recognised cargo surveyor is your primary defence against both the carrier and the underwriter invoking this exclusion.

How long do I have to notify my underwriter after discovering damage?

Your policy will specify a notification period, but the practical answer is: immediately. Delayed notification gives the underwriter grounds to argue that evidence has been lost, that the damage could have been mitigated, or that the cause cannot now be established. For cargo arriving at a UK or EEA port, appoint a surveyor before the goods leave the terminal. For damage discovered at your warehouse after delivery, notify us the same day and do not move or dispose of the damaged goods until a surveyor has inspected them.

My freight forwarder says their liability covers the damage — do I still need my own cargo policy?

Your freight forwarder's liability cover protects the forwarder against claims you make against them. It does not pay you directly, it is subject to the forwarder's own policy conditions and limits, and it will not respond if the forwarder can establish a defence under their standard trading conditions or the applicable carriage convention. Your own cargo policy responds to your loss regardless of who was at fault and without requiring you to prove negligence against anyone. The two covers serve different purposes and you need both.

What is a general average deposit and why would my cargo be held until I pay it?

When a vessel master declares general average, the shipowner is entitled to hold cargo until each cargo interest provides security for their proportional contribution to the shared sacrifice. That security is usually provided by a general average deposit or a general average guarantee from your cargo underwriter. If your policy includes a general average clause — as it should — your underwriter will issue the guarantee directly to the average adjuster and your cargo will be released. Without that clause, or without a policy in place at all, you will need to fund the deposit yourself before your goods are released.

Can I place cover after the shipment has already sailed?

In limited circumstances, yes — English law and London-market practice allow for retrospective cover where the assured had no knowledge of a loss at the time of placement. However, this is not a reliable fallback and underwriters will scrutinise the circumstances carefully. The correct approach is to have an open cover in place that binds automatically on each shipment at the time of sailing. If you are moving cargo without cover in place, contact us before the vessel arrives — do not wait until damage is confirmed.
