Marine Cargo Insurance: All-Risk vs Total Loss Explained

Why Cargo Insurance Is Not Optional

Here is what many shippers learn too late: the shipping line’s or airline’s liability for lost or damaged cargo is legally limited — often to a small fraction of your goods’ actual value under international conventions. If your container goes overboard or your pallet is crushed, the carrier’s payout will not make you whole. Marine cargo insurance exists to close that gap, and it is inexpensive relative to the risk.

Institute Cargo Clauses: A, B and C in Plain English

Most marine cargo policies worldwide are built on the Institute Cargo Clauses — a standard set published by the London insurance market. There are three levels:

Clause A — All-Risk (the broadest). Covers loss or damage from any external cause except what is specifically excluded. Dropped cartons, water damage, theft, rough handling — covered. This is the default choice for general merchandise, electronics and anything fragile or valuable.

Clause B — Named perils plus. Covers a listed set of risks: fire, explosion, vessel sinking or stranding, collision, jettison, washing overboard, water ingress, earthquake/volcanic eruption/lightning, plus total loss in loading/unloading and a few extras. Broader than C, narrower than A — a middle-ground option for sturdy, low-value cargo.

Clause C — Minimum cover (major casualties). Covers only the big disasters: fire, explosion, vessel sinking, stranding, collision, jettison, general average. If your cartons arrive crushed but the ship is fine, Clause C pays nothing. Suitable for bulk commodities where minor damage is a cost of doing business.

When Each Makes Sense

• Choose A for electronics, furniture, fragile goods, high-value commercial shipments — anything where partial damage would hurt.
• Choose B for durable, lower-value goods where you want more than bare-minimum protection without the all-risk premium.
• Choose C for bulk raw materials and commodities where only a catastrophe would cause a meaningful loss.

What Is Typically Excluded

Even all-risk policies have standard exclusions. Common ones include: improper packing (if you packed it badly, the insurer will not pay), inherent vice (goods that spoil or degrade by nature), delay (late arrival alone is not covered), ordinary wear and tear, and war, strikes and terrorism — though war and strikes can usually be added back for an additional premium, which is worth considering on certain routes. Read the exclusions before you buy, not after a claim.

How to File a Claim: The Basics

1. Act immediately. Note damage on the delivery receipt before signing, and notify your insurer and forwarder in writing as soon as possible — policies have strict time limits.

2. Preserve the evidence. Do not dispose of damaged goods or packaging until the insurer’s surveyor has inspected them.

3. Gather documents: the insurance policy/certificate, commercial invoice, packing list, bill of lading or air waybill, the survey report, and photos of the damage.

4. Submit a formal claim letter quantifying the loss with supporting invoices. Your forwarder or broker can usually help assemble the file.

FAQs

Is marine insurance mandatory?
Not by law for most cargo, but many buyers, banks (under letters of credit) and trade contracts require it. Even when optional, it is strongly advised.

What does “general average” mean?
If a vessel sacrifices cargo or incurs extraordinary costs to save the ship (e.g., jettisoning containers in a storm), all cargo owners share the loss proportionally — even if your goods were untouched. Insurance covers your contribution.

Does all-risk cover absolutely everything?
No — the standard exclusions (improper packing, inherent vice, delay, war/strikes unless added) still apply. “All-risk” means all fortuitous external risks.

How much does cargo insurance cost?
Premiums are typically a small fraction of the cargo’s insured value, varying with the goods, route and clause level. Get a quote per shipment — it is usually far cheaper than shippers expect.
