Marine Cargo Insurance Basics for Ocean Freight from Japan
A carrier’s liability for cargo loss is capped and full of exclusions — it isn’t a substitute for insurance. Here’s why that gap exists, how the standard coverage tiers compare, and who should be the one arranging cover.
01Why You Need Insurance in the First Place
A carrier’s liability isn’t open-ended. International convention and the terms printed on the bill of lading both cap the amount a carrier has to pay out for lost or damaged cargo — and in most cases that cap sits well below the actual value of the goods.
On top of the cap, carriers are also broadly excused from liability in a long list of situations: heavy weather damage, poor stowage where the shipper loaded the container themselves, and deterioration that’s simply inherent to the nature of the goods. Even a container lost overboard doesn’t guarantee full recovery of its value.
Marine cargo insurance is what closes that gap between what a carrier is obligated to pay and what the cargo is actually worth.
02ICC (A), (B), and (C) Compared
The Institute Cargo Clauses (ICC) are the standard basis for cargo insurance policies, offered in three tiers.
| ICC (A) | Broadest cover. Insures against all risks of loss or damage except for the specific exclusions written into the policy |
|---|---|
| ICC (B) | Named perils — fire, explosion, sinking, stranding, general average, and seawater damage among them |
| ICC (C) | Narrowest cover. Limited to major casualty events — fire, explosion, sinking, stranding |
If you want theft and rough-handling damage covered, (A) is the tier to start from. (C) carries a lower premium, but it leaves out a lot of what actually causes claims in day-to-day shipping.
War and strikes risk sit outside all three tiers and have to be added as separate cover. Depending on the situation, insurers may apply route-specific loadings to that add-on.
03Who Insures, and for How Much
Who’s responsible for arranging insurance comes down to the trade terms agreed on the sale. Under CIF and CIP, the seller is obligated to insure the cargo; under FOB and CFR, it’s left to the buyer to arrange on their own. The real failure mode in practice is when neither side arranges it because the terms never spelled out whose job it was.
Standard practice is to set the insured amount at 110% of the CIF value. The extra 10% is there to account for the profit margin and incidental costs that would otherwise be lost on top of the cargo’s own value if a claim has to be made.
What happens at the receiving end matters just as much as the policy itself. Inspection and documentation on arrival — photos taken during devanning, a survey report, and prompt notice of loss to the carrier — form the evidence base that a claim actually depends on.
FAQFAQ
How much does the premium typically cost?
It varies by cargo type, destination, and coverage terms. For most general cargo, the rate applied to the insured amount is small relative to the exposure, so it tends to be cost-effective set against the potential loss.
Should I insure my own shipment even on FOB terms?
Under FOB, risk transfers to the buyer at shipment, so the buyer is normally the one who insures. A seller may still want to consider a short-haul policy covering the pre-shipment leg, since that portion isn’t the buyer’s risk yet.
Where do I actually arrange this?
Through a non-life insurer or an insurance broker. If you ship regularly, an open (blanket) policy is simpler to administer than arranging coverage for each shipment individually.
