Cargo Insurance for UK Commodity Traders & Brokers

Institute Cargo Clauses A, B and C: What Each One Actually Covers

Institute Cargo Clauses (A) provide the broadest cover available under the standard London market wordings. They operate on an all-risks basis, meaning every physical loss or damage to your cargo is covered unless it falls within a named exclusion. For a commodity trader moving bulk metals or packaged chemicals, ICC (A) is the default starting point — not because it is the most expensive option, but because the exclusions in ICC (B) and (C) are wide enough to leave material gaps in cover for most traded commodities.

ICC (B) covers a defined list of named perils: fire, explosion, vessel stranding, grounding, sinking or capsizing, overturning or derailment of land conveyance, collision, discharge at a port of distress, earthquake, volcanic eruption, lightning, washing overboard, entry of sea, lake or river water, and total loss of any package lost overboard or dropped during loading or unloading. Theft, contamination, and most handling damage are not covered. If your commodity is susceptible to any of those risks — and most are — ICC (B) is rarely adequate.

ICC (C) is the most restrictive wording. It covers only major casualties: fire, explosion, vessel stranding, grounding, sinking, capsizing, overturning or derailment, collision, and discharge at a port of distress. It is sometimes used for low-value bulk cargoes where the premium saving justifies the narrower cover, but for a commodity trader with price exposure running into six or seven figures per shipment, ICC (C) is rarely the right choice. The question to ask yourself is not 'what is the cheapest clause?' but 'what is the maximum loss I can absorb if the clause does not respond?'

One point of practical importance: the current standard wordings are the 2009 revision of the Institute Cargo Clauses. Some legacy open covers — particularly those that have rolled over without a full re-broking — still incorporate the 1982 wordings. The exclusion structure and clause numbering differ between editions, and the 1982 wordings contain some provisions that were tightened or clarified in 2009. If you are not certain which edition your open cover incorporates, ask your broker to confirm this before your next renewal. Operating under the wrong edition can create unexpected gaps.

• ICC (A): all-risks less named exclusions — broadest cover, appropriate for most traded commodities
• ICC (B): named perils including entry of sea water and washing overboard — gaps in theft and handling damage
• ICC (C): major casualties only — suitable only where the premium saving is justified by low per-unit value
• All three clauses exclude inherent vice, delay, wilful misconduct of the assured, and war and strikes risks — see Clause 4 (general exclusions), Clause 6 (war exclusion) and Clause 7 (strikes exclusion)
• Confirm with your broker whether your open cover incorporates the 2009 or 1982 ICC wordings — the distinction matters for exclusion scope and claims handling

War, Strikes and the Exclusions That Matter Most to Commodity Traders

The standard ICC wordings exclude war, capture, seizure, derelict mines and torpedoes under Clause 6, and strikes, riots and civil commotions under Clause 7. Clause 4 sets out the general exclusions applicable to all three clause sets, including wilful misconduct of the assured, ordinary leakage and wear, inherent vice, delay, insolvency of shipowners, and unseaworthiness where the assured is privy to it. For commodity traders routing shipments through the Red Sea, the Strait of Hormuz, or transiting West African waters, these exclusions are not theoretical. You need Institute War Clauses (Cargo) and Institute Strikes Clauses (Cargo) endorsed onto your policy before the vessel enters a listed area — not after the incident is reported.

Joint War Committee (JWC) listed areas are reviewed regularly. When an area is added to the list, your open cover or voyage policy may require you to notify your broker immediately and pay an additional premium to maintain cover. Critically, for certain JWC-listed areas, Institute War Clauses (Cargo) cover may be unavailable entirely, or subject to held-covered provisions that require prior agreement with underwriters before the vessel sails. The assumption that war cover is always obtainable for an additional premium is wrong — in some areas, underwriters will decline to extend cover at any price, or will impose conditions that effectively restrict the transit. Your chartering desk, logistics team and insurance broker need to be in communication before a vessel is fixed for a voyage through a high-risk area, not after the bill of lading is issued.

Sanctions exclusions are also standard across all London market cargo wordings. If your counterparty, the vessel, the flag state or the port of call triggers a UK, EU or UN sanctions regime, your underwriter will decline to pay. This is not a negotiating point — it is a hard exclusion. Your trade compliance team and your broker need to be aligned on sanctions screening before cover is bound, not at the time of a claim.

General Average, Sue-and-Labour and Why They Affect Your Cash Flow

General average is one of the oldest principles in maritime law. When a shipowner or master makes a voluntary sacrifice — jettisoning cargo, engaging salvors, diverting to a port of refuge — to save the common adventure, every cargo interest contributes to the loss in proportion to the value of their goods. The York-Antwerp Rules govern how that contribution is calculated and adjusted. The current edition is York-Antwerp Rules 2016, but your bill of lading may incorporate the 1994 or 2004 edition instead — and the edition matters. Different editions treat items such as crew wages, fuel costs during deviation, and the methodology for calculating the GA fund differently, which affects both the size of your cash deposit requirement and the timeline for final adjustment. Before signing a bill of lading for a high-value shipment, check which edition of the York-Antwerp Rules it incorporates.

Under whichever edition applies, you may be required to provide a general average bond and a cash deposit or bank guarantee before the shipowner releases your cargo. Without cargo insurance, that deposit comes from your own funds and may be tied up for months or years while the average is adjusted. Your ICC (A), (B) or (C) policy covers your general average contribution, salvage charges, and special charges — but only if the loss or damage giving rise to the general average act would itself have been covered under your policy. This is the 'as if separately insured' test. If your cargo was excluded from cover for any reason, your general average contribution is also excluded.

The sue-and-labour clause in your cargo policy requires you to take reasonable steps to avert or minimise a loss, and entitles you to recover the reasonable costs of doing so from your underwriter — even if those steps ultimately fail to prevent the loss. In practice, this means engaging surveyors, arranging emergency storage, or diverting a consignment to prevent further deterioration. Document every step and every cost. Underwriters will scrutinise sue-and-labour claims carefully, and your ability to recover depends on demonstrating that the expenditure was reasonable and necessary. Note also that hull underwriters writing the carrying vessel may invoke the Inchmaree clause to cover latent defects in machinery or hull that caused the casualty — if that triggers a general average, your cargo policy's GA contribution cover becomes directly relevant to your cash flow position even where the underlying cause was a machinery failure rather than a navigational incident.

Open Covers, MRC Slip Declarations and Claims Notification

If you are moving cargo regularly — weekly or monthly shipments of the same commodity type — an open cover is almost always more efficient than placing individual voyage policies. An open cover is a master agreement with your underwriter that automatically attaches to each shipment as you declare it, within agreed limits of liability per vessel, per location, and per commodity type. Under London market practice, each declaration is lined on the MRC slip and must include, at minimum: vessel name, IMO number, bill of lading value, commodity description, and ports of loading and discharge. Incomplete declarations — missing IMO numbers or undeclared transhipment legs, for example — can create attachment disputes at the time of a claim. Build the declaration discipline into your operations team's workflow, not just your broker's.

The declaration discipline matters for a further reason. Under a London market open cover, you are typically required to declare all shipments attaching to the cover, not just the ones you consider high-risk. If you selectively declare only the shipments you are worried about, you are in breach of the duty of fair presentation under the Insurance Act 2015, and your underwriter may have grounds to avoid the policy or reduce the claim payment. Declare everything, on time, and keep a record of your declarations.

When a loss occurs, the claims notification cascade is time-critical. First, notify your broker immediately — do not wait for a survey report or a carrier's response. Second, instruct a surveyor at the port of discharge before the cargo is moved or interfered with; survey evidence is often the only contemporaneous record of condition on arrival. Third, serve written notice of claim on the carrier within the time limits imposed by the applicable carriage convention — under the Hague-Visby Rules, that is one year from delivery or the date delivery should have taken place. Missing that time bar does not just affect your direct claim against the carrier; it extinguishes your underwriter's subrogation rights, which underwriters take seriously and which can affect their willingness to pay without argument. Preserve the subrogation chain from day one.

• Open cover: automatic attachment on declaration — best for regular, repeat shipments
• MRC slip declarations must include vessel name, IMO number, bill of lading value, commodity, and ports of loading and discharge
• Voyage policy: standalone placement for one-off or unusual consignments
• Declarations must cover all attaching shipments — selective declaration risks a breach of fair presentation
• Claims cascade: immediate broker notification, surveyor instruction at port of discharge, written notice to carrier within convention time limits
• Limits per vessel, per location and per commodity type must reflect your actual maximum exposure, not your average shipment value

What to Bring to Your Broker When Placing or Renewing Cargo Cover

The Insurance Act 2015 replaced the Marine Insurance Act 1906 duty of disclosure with a duty of fair presentation. In practice, this means you must disclose every material circumstance that a prudent underwriter would want to know, in a manner that is reasonably clear and accessible. For commodity traders, this includes your commodity types and grades, annual shipment volumes and values, trading routes and ports of call, packaging and storage conditions, loss history for the past five years, and any known quality or condition issues with the goods at the time of shipment.

Your broker should be asking the underwriter, on your behalf, about the basis of valuation (agreed value versus invoice value plus a percentage), the currency of settlement, the survey requirements at destination, and the claims notification procedure. These are not administrative details — they determine how quickly you are paid and how much you receive. Agreed value policies avoid disputes about market price movements between shipment and loss; invoice-plus policies may leave you underinsured if commodity prices have risen sharply.

Premium is shaped by a range of factors that your broker should be presenting clearly to underwriters: commodity type and whether it is bulk or packaged, stowage position (on-deck versus under-deck), trading route and whether any JWC-listed areas are in scope, your loss history and its causes, and whether cover is placed on an agreed value or invoice-plus basis. Each of these affects how underwriters price and structure the risk. Understanding which factors are driving your premium allows you to have an informed conversation at renewal rather than simply accepting the number presented.

On renewal, bring your full declarations record for the expiring period, your updated trading programme for the coming year, and any changes to your counterparties, routes or commodity types. If your trading book has expanded into new geographies or new commodities, tell your broker before renewal, not after the first loss under the new programme.

• Commodity types, grades and annual shipment values
• Trading routes, ports of call and any JWC-listed areas in your programme
• Packaging, containerisation, on-deck or under-deck stowage details
• Five-year loss history with cause and quantum
• Bill of lading terms and any sale contract Incoterms (CIF, CFR, FOB) that affect who bears the insurable interest
• Any known quality or condition issues at the time of shipment
• Confirmation of which ICC edition (2009 or 1982) your current open cover incorporates

Carriage Conventions and Your Rights Against the Carrier

Your cargo insurance responds to physical loss or damage regardless of fault. But your underwriter, having paid your claim, will subrogate against the carrier if the carrier was at fault. The extent of that recovery — and therefore the underwriter's appetite to pay your claim without argument — depends on which carriage convention governs your bill of lading.

The Hague-Visby Rules, incorporated into English law by the Carriage of Goods by Sea Act 1971, apply where the bill of lading so provides or where the rules are compulsorily applicable by statute to the particular voyage. Applicability is not automatic for all UK-origin or UK-destination shipments — it depends on the bill of lading terms and the route. Where the Hague-Visby Rules do apply, they cap the carrier's liability per package or per kilogram. For high-value commodities, that cap is almost always less than your actual loss. The Hamburg Rules and the Rotterdam Rules offer different liability regimes and higher caps in some cases, but their adoption is uneven. What matters to you as a cargo owner is knowing that your insurance fills the gap between what the carrier pays and what you actually lost — which is precisely why the basis of valuation in your cargo policy matters so much.

As noted above, the one-year Hague-Visby time bar for claims against the carrier is not merely a procedural deadline — it is the mechanism by which your underwriter's subrogation rights are preserved or lost. If you fail to serve written notice of claim on the carrier within that period, your underwriter loses the ability to recover from the carrier after paying your claim. Some underwriters treat this as a condition of the policy. Serve notice, keep records, and instruct your broker and legal advisers promptly when a loss occurs.

If your sale contract is on FOB terms, the risk passes to you at the ship's rail and you are responsible for arranging cargo insurance from that point. If it is CIF, the seller provides insurance, but the policy is in their name and may be on minimum terms that do not reflect the full value of your purchase or the specific risks of the transit. If there is a loss, you may find the seller's policy does not respond adequately to your claim. Taking out your own cargo insurance, or requiring the seller to provide a policy that meets your minimum standards, protects your position. Your broker can advise on how to structure this without duplicating cover unnecessarily.

Frequently asked questions

Do I need Institute Cargo Clauses (A) or will (B) or (C) do for bulk commodity shipments?

For most traded commodities — metals, grains, chemicals, energy products — ICC (A) is the appropriate starting point. ICC (B) and (C) leave gaps in cover for theft, contamination and handling damage that are material risks for commodity cargoes. The question is not which clause is cheapest, but which clause responds to the losses you are most likely to suffer. Your broker should walk you through the specific exclusions in (B) and (C) — including the general exclusions in Clause 4 — against your commodity type before recommending a narrower wording.

What happens if my shipment transits a JWC-listed war risk area and I haven't endorsed war cover onto my policy?

The standard ICC wordings exclude war risks under Clause 6. If your vessel enters a JWC-listed area without Institute War Clauses (Cargo) endorsed onto your policy, your cargo is uninsured for war-related losses during that transit. You need to notify your broker before the vessel is fixed for the voyage, not after the bill of lading is issued. For some JWC-listed areas, war cover may not be available at any price, or may only be available subject to held-covered provisions requiring prior underwriter agreement. Do not assume that additional premium is always sufficient to secure cover.

How does the duty of fair presentation under the Insurance Act 2015 affect my open cover declarations?

You must declare all shipments attaching to your open cover, not just the ones you consider high-risk. Selective declaration — only declaring shipments you are worried about — is a breach of your duty of fair presentation and gives your underwriter grounds to avoid the policy or reduce a claim payment. Declare everything, on time, and keep a record of your declarations.

What do I need to provide to get a quote for a cargo open cover?

At a minimum: your commodity types and grades, estimated annual shipment values, trading routes and ports of call, packaging or stowage details, five-year loss history, and the Incoterms under which you typically trade. If you have an expiring policy, bring the declarations record and the current policy wording — including confirmation of whether it incorporates the 2009 or 1982 ICC edition. The more complete the information, the more accurately your broker can approach the market on your behalf. Timelines to bind depend on the complexity of your programme and the completeness of the submission.

My sale contract is CIF — does that mean I don't need my own cargo insurance?

Under CIF terms, the seller provides cargo insurance, but the policy is in the seller's name and may be on minimum terms that do not reflect the full value of your purchase or the specific risks of the transit. If there is a loss, you may find the seller's policy does not respond adequately to your claim. Taking out your own cargo insurance, or requiring the seller to provide a policy that meets your minimum standards, protects your position. Your broker can advise on how to structure this without duplicating cover unnecessarily.

What is the claims notification cascade and why does it matter?

When a loss occurs, notify your broker immediately — before moving or interfering with the cargo. Instruct a surveyor at the port of discharge to record condition on arrival. Then serve written notice of claim on the carrier within the time limits under the applicable carriage convention; under the Hague-Visby Rules, that is one year from delivery or the date delivery should have taken place. Missing that time bar extinguishes your underwriter's subrogation rights against the carrier, which can affect how your claim is handled. The cascade is: broker notification, surveyor instruction, written notice to carrier — in that order, as quickly as possible.
