All Risks vs Named Perils in Marine Cargo Insurance: What's the Difference

Two shippers can each buy "marine cargo insurance" and end up holding genuinely different products, because that phrase describes a category, not a single kind of coverage. The real question a policy answers isn't just "is this cargo insured" but "insured against what, exactly" — and that's where All Risks and Named Perils, the two dominant coverage structures, diverge in ways that matter a great deal at claim time.

Neither structure is inherently better; they're built on opposite logic. One starts from broad coverage and narrows it with exclusions. The other starts from no coverage and builds it up peril by peril. Understanding which logic a policy uses — and what that means practically when something actually goes wrong with a shipment — is the difference between buying coverage that matches the real risk and buying a policy without knowing what it actually protects against.

What All Risks Coverage Means

An All Risks policy is built on a broad default: loss or damage from any cause is covered, unless that cause falls under one of the exclusions specifically listed in the policy. In practice, that means the coverage question at claim time is framed around the exclusions rather than around whether the cause of loss happened to be on an approved list. If the cause of loss isn't specifically excluded, it's generally within scope.

This structure tends to favor the insured in disputed claims, because the practical burden sits with the insurer to identify and demonstrate that a specific exclusion applies in order to deny coverage — rather than the shipper having to prove the loss matches a named cause. That doesn't mean every claim under an All Risks policy is straightforward; disputes still happen over whether a stated exclusion genuinely applies to the facts of a particular loss. But the starting position is coverage, which is the defining feature that gives the "All Risks" name its meaning.

What Named Perils Coverage Means

A Named Perils policy works from the opposite starting point: nothing is covered by default, and coverage exists only for the specific causes of loss explicitly listed in the policy. Common named perils in marine cargo policies include things like fire, vessel sinking or stranding, collision, and general average sacrifice — but the exact list varies by policy, and a peril that isn't listed simply falls outside what's insured, regardless of how reasonable or common that cause of loss might be.

The practical consequence is a reversed burden compared to All Risks: if a claim is made, the party claiming generally needs to demonstrate that the actual cause of the loss matches one of the perils named in the policy. For a loss with an obvious, well-documented cause that clearly matches a listed peril — cargo damaged in a documented vessel fire, for instance — this isn't a heavy burden. But for a loss with an ambiguous or hard-to-pin-down cause, a Named Perils policy can leave more room for dispute over whether the loss actually falls within scope.

The Key Structural Difference: Where the Burden Sits

Stripping away the specifics, the essential difference between the two comes down to which party has to make an argument, and about what. Under All Risks, the shipper's baseline position is favorable — coverage applies unless the insurer identifies and proves a specific exclusion. Under Named Perils, the shipper's baseline position requires an affirmative step — coverage applies only once the claimant shows the loss matches a named cause.

This matters most in situations where the exact cause of a loss is genuinely unclear, which happens more often in real shipping than it might seem. Cargo can arrive damaged without a clean, single, documented cause — rough handling somewhere along a multi-leg journey, condensation from temperature swings inside a container, or a combination of contributing factors that aren't easy to isolate. In those ambiguous situations, the difference in where the burden sits can directly determine whether a claim succeeds.

What's Excluded Even Under an All Risks Policy

It's a common misconception that "All Risks" means literally every possible cause of loss is covered — it doesn't. Standard exclusions typically appear in All Risks policies regardless of insurer, and understanding them matters just as much as understanding what's included. Inherent vice — loss caused by the natural characteristic or tendency of the goods themselves, such as ordinary spoilage of a perishable product under normal conditions — is a near-universal exclusion, because it's a property of the goods rather than an external risk of transit.

Inadequate or improper packing is another common exclusion, since the insurer's coverage generally assumes the goods were prepared for shipment in a way suitable for the transit conditions they'd reasonably face — if packing itself was the failure point, that shifts responsibility away from a transit risk and toward a preparation issue. Loss caused by delay, as opposed to loss caused by a physical event, is also typically excluded, since delay-related loss (such as a market price drop while goods sit in transit longer than expected) is a different category of risk than physical loss or damage to the cargo itself. War and strikes risks are also commonly carved out as separate, often optional coverage rather than being bundled into a standard All Risks policy.

How Premium Reflects the Difference in Scope

Because All Risks starts from a broader default position, it generally carries a higher premium than Named Perils coverage for comparable cargo and route — the insurer is taking on a wider range of potential causes of loss, and that broader exposure is priced accordingly. Named Perils, by covering only a defined and typically narrower set of causes, generally comes at a lower premium, reflecting the more limited scope of what the insurer is actually on the hook for.

That premium difference is the practical trade-off shippers weigh: broader, more shipper-friendly coverage at a higher recurring cost, versus narrower, more sharply defined coverage at a lower cost that works fine as long as the cargo's actual risk exposure stays within what's named. Neither choice is automatically the more cost-effective one — it depends on how the premium difference compares to the realistic likelihood and cost of a loss falling outside a Named Perils list for that specific cargo and route.

How to Decide Which Policy Type Fits a Given Shipment

The decision generally starts with the nature of the cargo and how much handling and transit variability it's exposed to. High-value goods, fragile items, or cargo moving through multiple handling transfers and transshipment points carry more exposure to causes of loss that are hard to predict in advance — for that kind of cargo, the broader default protection of All Risks reduces the chance that an unusual but real cause of damage falls outside what's covered. Bulk commodities with well-understood, limited risk profiles moving on a straightforward route may be adequately protected by a Named Perils policy that names the realistic causes of loss for that specific trade.

Budget is a legitimate factor too, but it's worth weighing against how much is riding on a claim actually being paid without dispute. For cargo where even a single denied or contested claim would be costly, the lower burden of proof and broader default coverage of All Risks is often worth the higher premium. For lower-value, well-understood cargo shipped repeatedly on a stable route, a Named Perils policy that's been matched carefully to the real risks involved can be a reasonable and more economical choice.

Reading a Policy Document With This Distinction in Mind

Once the general structure is clear, reading an actual policy document becomes a much more targeted exercise. For an All Risks policy, the section worth reading most carefully is the exclusions clause — that's where the real boundaries of coverage live, since the insuring clause itself is usually a short, broad statement of coverage. For a Named Perils policy, the opposite is true: the list of named perils itself is the section that matters most, since anything not on that list is effectively outside the policy regardless of how the rest of the document is worded.

It's also worth checking whether a policy that's labeled "All Risks" in its marketing or cover page actually reads that way in its operative clauses, since terminology can vary between insurers and jurisdictions. The safest approach is to read the actual insuring clause and exclusions or perils list directly, rather than relying on the policy's name alone, and to ask the insurer or broker to clarify anything that reads ambiguously before a shipment moves rather than after a loss has already occurred.
