Is cargo insurance worth it? What carriers actually owe you

$500. That's the maximum an ocean carrier owes you for a lost container under U.S. COGSA — per package, and if the bill of lading describes your container as one package, that's $500 for the whole box, whatever's inside it. Air is better and still brutal: 26 SDR per kilogram, roughly $35/kg at recent exchange rates. Cargo insurance exists because those caps are the law's default, not your recovery. Whether it's worth it comes down to one comparison: the capped amount the carrier actually owes you versus what the goods are worth to you. This article runs that comparison on real numbers and leaves you with a per-shipment decision rule.

A boundary first: this article covers goods in transit. Stock at rest — the warehouse copy of the same goods — is a different risk with its own product, covered in the inventory insurance guide.

What the carrier owes you: three regimes, three caps

One door-to-door journey crosses several liability regimes, and each has its own cap:

(SDR — special drawing right — is the IMF's basket currency unit; the dollar value moves with exchange rates.)

The air cap deserves a worked example, because the arithmetic shocks people. Jade International's: 100 kg of electronics worth $50,000. At 26 SDR/kg, the carrier's maximum is 2,600 SDR — roughly $3,500, exchange-rate dependent. A $50,000 loss recovering about 7% of its value, before you've spent a dollar on the claim.

The container trap: one package, $500, total loss

The ocean cap says "per package," which sounds fine until you meet the paperwork. If the bill of lading describes a full container as a single package — one line, "1 x 40FT HC CONTAINER" — then a total loss may recover $500 regardless of contents (Jade International, as of October 2026). A container holding $18,000 of goods can be legally, contractually, a $500 package.

The fix lives on the carrier's terms: declare a value on the bill of lading. Declared value both sets the recovery ceiling and usually settles the package-count argument. It costs a valuation charge — and it's still the carrier's claims process, subject to the carrier's defenses, which is why the next section compares it against a policy.

Three coverage routes compared

The policy route matters because of what it removes: fault. An all-risk marine cargo policy written under Institute Cargo Clauses (A) covers physical loss or damage "from any cause not specifically excluded" — you don't have to prove the carrier was negligent, only that the goods were lost or damaged. Narrower named-peril cover under ICC (C) costs less and pays out on a shorter list of causes; it's the budget option where the budget is the point (Jade International, as of October 2026).

A per-shipment decision rule, worked on $18,000

Take a container of enamel-pin counter displays, invoiced at $16,400, with an estimated $1,500 in ocean freight and a nominal insurance charge — call the CIF value $18,000 (illustrative). Marine cargo policies conventionally insure CIF value plus 10% (Jade International), so the insured value is $19,800.

Now the routes on a total loss:

• Self-insured, B/L reads "1 container": one package → recovery $500. That's 500 / 18,000 = 2.8% of CIF value.
• Same container described as 24 packages: 24 × $500 = $12,000. Better, still $6,000 short of CIF.
• Declared value at $18,000: full CIF recovery available, subject to the carrier's claims process and defenses.
• All-risk policy at $19,800: full insured value available, no fault to prove, minus your deductible.

The decision rule: insure any shipment whose total loss would hurt more than its premium — which, at the caps above, is nearly every containerized shipment carrying real value. Self-insurance is a deliberate choice for genuinely low-value or highly replaceable freight, not a default. Premiums vary by route, commodity, and volume; get quotes rather than guessing.

The exclusions that void otherwise-good cover

An all-risk policy is not "all-risk" in plain English. The exclusions that actually bite small importers:

• Inadequate packing. Goods lost or damaged because pallets were sloppy, cartons undersized, or crating insufficient are typically excluded. The packing decisions made at the factory are insurance decisions — and the documentation that survives a packing dispute is covered in the freight damage claim guide.
• Inherent nature or vice of the goods. Coffee beans that age in transit, candles that soften in a hot hold — the goods behaving as goods do isn't a covered peril.
• Delay. Even when the cause is covered, the delay itself usually isn't: the policy pays for the goods, not for the sales you missed while they were late.
• War and strikes. Usually excluded from base cover but addable by endorsement when the route calls for it (Jade International, as of October 2026).

General average: the clause most merchants meet only once

Here's the one most readers have never met. When a ship is in peril, the master may make an intentional sacrifice to save the voyage — jettisoning containers in a storm, hiring a tug after engine failure, running the vessel aground to keep it off the bottom. Under the maritime doctrine of general average, the cost of that sacrifice is shared pro-rata by all cargo interests, including the ones whose cargo was never touched (Jade International; Flexport glossary, as of October 2026).

The part that surprises people isn't the bill — it's the hold. Cargo can be retained until each owner posts security for their share of the contribution. Your undamaged container sits at the terminal until the money is arranged.

A cargo policy typically covers the general average contribution and, just as usefully, provides the security guarantee so your goods release without you posting a bond yourself. It's among the least glamorous arguments for carrying coverage: the policy earns its premium most visibly on the day your goods arrive fine and still need to get out of the yard.

When the answer is "yes," the arithmetic continues

If you insure, the insured value flows into your per-unit economics the same way freight does — a shipment's true cost per unit includes the premium and the worst-case gap you've decided to carry. how landed cost is assembled shows where that freight-and-risk slice sits.

Common questions

Is cargo insurance worth it for small importers? Decide per shipment: compare the carrier's capped liability — $500 per package by ocean, about $35/kg by air — against the shipment's CIF value. If a total loss would hurt more than the premium would, insure. For most containerized goods worth thousands, the cap recovers a fraction of value, which makes all-risk cover the sensible default.

What does the carrier pay if my container is lost at sea? Under COGSA, $500 per package or customary freight unit unless a higher value was declared on the bill of lading. If the B/L describes the whole container as one package, a total loss may recover $500 regardless of contents. Declared value raises the ceiling.

How is cargo insured value calculated? The standard convention is CIF value plus 10% — cost of goods, insurance, and freight, plus a 10% cushion for associated charges (Jade International). On an $18,000 CIF container load, that's an insured value of $19,800. Confirm the convention with your insurer when you bind cover.

What is general average in shipping? A maritime doctrine: when cargo is intentionally sacrificed to save a voyage — containers jettisoned in a storm, a tug hired after engine failure — all cargo interests share the cost pro-rata, even those whose goods were undamaged. Cargo can be held until security is posted; cargo policies typically cover the contribution and provide the guarantee.

What's the difference between all-risk and named-peril cargo cover? All-risk under Institute Cargo Clauses (A) covers physical loss or damage from any cause not specifically excluded — no proof of carrier fault needed. ICC (C) covers a named list of perils only, and costs less. Most merchants shipping goods they'd hate to lose want the (A) form.

Next step

Pull your last bill of lading and read two things: how many "packages" the container is described as, and whether any value was declared. Compute your actual capped recovery for a total loss — the worked example above shows the arithmetic. If the gap between that number and your CIF value made you wince, get two cargo insurance quotes (premiums vary more between brokers than between policies), and start building the packing and documentation habits from the freight damage claim guide before the next shipment books.
