Chubb Marine Cargo Insurance: UK Buyer's Guide

Written by the London Marine Insurance editorial team · reviewed by Anton Kuznetsov, founder

If you are a UK or EEA shipping company, freight forwarder, or cargo owner researching Chubb marine cargo insurance, the decision you are really making is whether a company-market policy placed through a specialist London-market broker gives your consignments the breadth of cover, claims service, and financial security your contracts demand. Chubb is one of the largest company-market marine underwriters accessible through the London market, and their cargo wordings are routinely benchmarked against Institute Cargo Clauses (A), the broadest standard form available under English law. This guide explains what that cover actually does for you, where the gaps sit, and what you need to bring to your broker before we approach underwriters on your behalf.

What Chubb Marine Cargo Cover Actually Provides

Chubb's marine cargo policies are typically written on an all-risks basis aligned to Institute Cargo Clauses (A), which cover all risks of physical loss or damage to your goods during transit unless a specific exclusion applies. That is materially broader than ICC (B) or ICC (C), which only cover named perils. If your sale contract is on CIF or CIP Incoterms 2020 terms, your counterparty will expect ICC (A) as the minimum — anything narrower can leave you in breach of the trade contract before a claim even arises.

Beyond the core all-risks cover, a well-structured Chubb cargo policy will include sue-and-labour provisions, which reimburse reasonable costs you incur to avert or minimise a loss. This matters practically: if your container is damaged at Felixstowe and you pay for emergency re-packing to prevent further deterioration, those costs should be recoverable under sue-and-labour rather than coming out of your own pocket. Your broker should confirm this clause is active and not subject to a sub-limit that makes it commercially useless.

General average is the other mechanism that catches cargo owners off-guard. Under the York-Antwerp Rules (most commonly the 2016 revision), if a vessel master declares general average — say, after jettisoning cargo to save the ship — every cargo interest must contribute to the shared loss proportionally, and your goods may be held at the discharge port until you provide a general average bond and, if required, a cash deposit. A properly structured cargo policy will pay your general average contribution and furnish the bond on your behalf. Without it, you are negotiating with a P&I club and a shipowner's average adjuster while your cargo sits in a bonded warehouse accruing storage charges.

Key Exclusions You Must Understand Before Binding

No cargo policy — Chubb's included — covers everything. The standard Institute Cargo Clauses exclusions that most frequently affect UK and EEA shippers are worth knowing before you sign a policy schedule, not after a claim is declined.

Inherent vice is the most commonly misunderstood exclusion. If your goods deteriorate because of their own nature — fresh produce that spoils, hygroscopic cargo that absorbs moisture, batteries that self-discharge — the loss is excluded regardless of how broad your cover is. Specialist temperature-controlled or perishables extensions exist, but they must be explicitly endorsed onto the policy.

War and strikes cover is excluded from the base ICC (A) wording and must be added separately under Institute War Clauses (Cargo) and Institute Strikes Clauses (Cargo). If your supply chain passes through the Red Sea, Bab-el-Mandeb, or the Strait of Hormuz — all currently listed as enhanced-risk trading areas — your broker needs to confirm that war cover is in place and that the policy responds to deviation, delay, and re-routing costs triggered by those threat areas, not just physical damage.

  • Inherent vice and gradual deterioration
  • Wilful misconduct of the assured
  • Ordinary leakage, wear and tear, and inadequate packing (ICC Clause 4)
  • War, strikes, riots, and civil commotion (unless separately endorsed)
  • Delay, even if caused by an insured peril (loss of market is not covered)
  • Insolvency of the carrier — a growing exposure on container trades
  • Nuclear and cyber perils (cyber exclusion CL380 is standard; affirmative cyber cover requires a separate endorsement)

How the Carriage Convention Affects Your Cargo Claim

Your cargo policy sits alongside — not instead of — your rights against the carrier. Under the Hague-Visby Rules, which govern most UK sea carriage under the Carriage of Goods by Sea Act 1971, the carrier's liability is limited per package or per kilogram, whichever is higher. For high-value or dense cargo, that limit is often a fraction of the actual loss. Your cargo insurer pays the gap, then exercises subrogation rights against the carrier in your name.

Hamburg Rules and Rotterdam Rules offer different liability frameworks, but Hague-Visby remains the operative regime for most UK-origin bills of lading. What this means practically is that your cargo policy needs to be sized to your full cargo value, not to what you think the carrier will pay. Underinsurance — whether through a stale declared value or a policy limit set below the replacement cost of your peak shipments — is the single most avoidable reason cargo claims are only partially settled.

If you are a freight forwarder issuing your own house bills of lading, you are stepping into the carrier's liability position. Your freight liability cover (often written under BIFA Standard Trading Conditions or FIATA terms) interacts directly with your cargo policy. Your broker should be reviewing both simultaneously, not treating them as separate placements.

Open Cover vs Specific Voyage: Choosing the Right Structure

If you are moving goods regularly — whether as a shipper, freight forwarder, or vessel operator — an open cover (also called a floating policy) is almost always more efficient than insuring each shipment individually. Under an open cover, you declare shipments as they arise against a master policy with agreed terms, rates, and conditions. Chubb and other specialist underwriters in the company market write open covers for UK and EEA cargo interests across a wide range of commodities and trade lanes.

The discipline an open cover imposes is declaration compliance. Your policy will require you to declare all shipments within a defined period — typically monthly. Failure to declare on time, or under-declaring values, can give underwriters grounds to reduce or void a claim. Your broker should build a declaration workflow into your placement from day one, not leave it as an administrative afterthought.

Specific voyage policies remain appropriate for one-off, high-value, or unusual shipments — project cargo, fine art, machinery, or consignments moving on non-standard routes. For these, your broker will approach underwriters with a full risk submission: commodity, packing, stowage, vessel details, and the full transit itinerary. The more complete the submission, the more competitive the terms you will receive.

What to Bring to Your Broker Before We Approach Underwriters

Underwriters price marine cargo risk on information. A thin submission produces either a wide deductible, a restrictive warranty, or a declination. The more precisely you can describe your operation, the more accurately we can negotiate terms that reflect your actual risk rather than a worst-case assumption.

For an open cover submission, you will typically need to provide a commodity description, annual shipment volume and aggregate value, primary trade lanes and ports of loading and discharge, packing and containerisation methods, any temperature or humidity requirements, your loss history for the past three to five years, and any existing carrier contracts or service level agreements that affect your liability exposure.

For a specific voyage or project cargo submission, add: vessel name and class, bill of lading terms, survey requirements at origin and destination, any pre-shipment inspection reports, and the full transit schedule including any transhipment ports. If the cargo is moving through a port with known congestion or security issues — Jebel Ali, for instance, during periods of regional tension — underwriters will want to know your contingency routing.

  • Commodity type, packing method, and containerisation details
  • Annual shipment values and frequency (for open cover)
  • Trade lanes, ports of loading and discharge, and transhipment points
  • Vessel details and classification society (for specific voyage)
  • Three to five years of claims history
  • Existing carrier contracts and any back-to-back liability arrangements
  • Any temperature, humidity, or handling requirements
  • Current policy schedule and expiry date

Renewal, Claims, and Getting the Most from Your Policy

Renewal is the moment to renegotiate, not just renew. If your trade lanes have changed, your commodity mix has shifted, or your shipment values have grown since the last placement, your existing policy may be misaligned with your current exposure. Bring your broker a full picture of changes at least 60 days before expiry — that gives us time to approach multiple underwriters in the company market and the London market rather than accepting the incumbent's terms by default.

When a loss occurs, notify your broker immediately and preserve all evidence: bills of lading, packing lists, survey reports, photographs, and any correspondence with the carrier. Under the sue-and-labour obligation, you are required to take reasonable steps to minimise the loss — but you are also entitled to be reimbursed for those steps. Do not wait for a formal claim to be lodged before acting; waiting can both worsen the loss and give underwriters grounds to argue you failed your duty.

Subrogation is your insurer's right to pursue the carrier or third party responsible for the loss in your name, after they have paid your claim. In practice, this means your insurer may require you to preserve your rights against the carrier — do not sign any release or limitation agreement with a carrier without first consulting your broker. Signing away your rights prematurely can reduce or eliminate your insurer's ability to recover, which in turn affects your claims record and your renewal terms.

Frequently asked questions

Do I need ICC (A) cover, or will ICC (B) or (C) be sufficient for my shipments?
It depends on your trade contract and your commodity. If you are selling on CIF or CIP Incoterms 2020, your buyer will typically require ICC (A) as the minimum. ICC (B) and (C) cover only named perils and leave significant gaps — for example, ICC (C) does not cover theft or contamination. For most general cargo moving on container trades, ICC (A) is the appropriate starting point, with specific extensions added for war, strikes, and any temperature or handling requirements.
What happens if the carrier limits their liability and my cargo loss exceeds that limit?
Under Hague-Visby Rules, the carrier's liability is capped per package or per kilogram. For many commodities, that cap is well below the actual value of the goods. Your cargo policy is designed to bridge that gap — it pays your full insured loss and then pursues the carrier through subrogation. This is precisely why insuring to full replacement value, not to what you expect the carrier to pay, is essential.
How long does it take to bind an open cover for regular shipments?
For a straightforward commodity on established trade lanes with a clean claims record, we can typically have terms agreed and a cover note issued within five to ten working days of receiving a complete submission. Complex risks — project cargo, hazardous materials, or routes through enhanced-risk areas — take longer because we need to approach specialist underwriters and may require a survey or additional information. Start the process at least 30 days before your current cover expires.
Does my cargo policy cover general average contributions if the vessel declares an emergency?
Yes, provided your policy is correctly structured. A standard ICC (A) policy includes general average and salvage charges under Clause 2. Your insurer will pay your proportional contribution and, critically, will provide the general average bond required to release your cargo from the shipowner's lien. Without this, your goods can be held at the discharge port indefinitely while the average adjustment is calculated — a process that can take months or years on a complex casualty.
I am a freight forwarder issuing house bills of lading. Do I need separate cover from my clients' cargo policies?
Yes. When you issue a house bill of lading, you are accepting carrier liability to your client. Your client's cargo policy will pay their loss and then subrogate against you as the contracting carrier. Your freight liability policy — written under BIFA, FIATA, or a bespoke wording — covers your exposure in that subrogation action. The two policies need to be reviewed together to ensure there are no gaps between what your client's cargo insurer can recover from you and what your liability policy actually covers.
What do you need from me to get a quote?
For an open cover: a description of your commodities, annual shipment values, primary trade lanes, packing and containerisation methods, and three to five years of claims history. For a specific voyage: all of the above plus vessel name and class, bill of lading terms, full transit itinerary including transhipment ports, and any pre-shipment survey reports. The more complete your submission, the more competitive the terms we can negotiate on your behalf.
