Your Cargo Is Out at Sea — Who Pays When It Goes Wrong?
Cargo & Trade Insurance for China Sourcing — The Premium You Resent Until You Need It

Hello, this is GreenFrog Seoul.

"Is cargo actually getting damaged at sea a common thing? It sounds like someone else's problem."
"We signed CIF, so the seller buys the insurance — that means I don't have to worry about it, right?"
"Half my shipment arrived water-damaged and unusable. The forwarder says it's not their responsibility. Where do I recover this from?"

Cargo insurance is the line item most easily postponed in sourcing. The premium is visible; the accident isn't. After a few shipments arrive safely, "I probably don't need this" starts to feel reasonable. Then one problem hits and you lose, in a single stroke, dozens of times what you saved on premiums. Your cargo spends days to weeks in other people's hands and out on the water before it reaches your warehouse, and what happens in that stretch is beyond your control.

Here's the point up front: cargo insurance is less a "just in case" safeguard than a baseline cost of doing international shipping. You pay roughly 0.1–0.3% of the invoice value — a few thousandths of the goods' price — to transfer the risk of total loss. The question isn't "insure or not," it's "with what cover, in whose name, and for how much." Get this wrong and you can be insured and still recover nothing.

Today we work through that structure: who carries the insurance responsibility under each Incoterm, what separates ICC(A)/(B)/(C) cover, how you buy it and how you file a claim when something goes wrong, and finally what cargo insurance never covers and the different territory that trade insurance (K-SURE) fills.

1. Why Cargo Insurance Matters — The Risk in the Stretch You Can't Control

From the moment goods leave the factory until they reach your warehouse, they pass through a long chain: truck, port, ocean vessel, transshipment, and truck again. The accidents in that stretch come in more varieties than you'd expect, and most of them aren't your fault — yet the loss lands on you.

• Flooding & moisture damage — Waves hit a deck-stowed container, or a temperature swing produces condensation inside it, soaking paper, textiles, and electronics. The outside can look fine while the inside is growing mold
• Breakage — Drops during handling, or cargo shifting inside the container and knocking together. Common with impact-sensitive items like glass, ceramics, and appliances
• Loss & theft — A whole shipment goes missing during transshipment, or the container seal is broken and part of the quantity is missing on arrival
• Total loss — Ship fire, grounding, sinking. Rare, but it actually happens — a major container-ship fire or accident makes the news every few years. In these cases the cargo vanishes entirely

General Average — When You Pay Even Though Your Cargo Is Fine

The least-known but most alarming reason to carry cargo insurance is general average. If a ship in peril jettisons some cargo or incurs extraordinary expense to save the whole vessel, that loss is shared among all the surviving cargo owners in proportion to cargo value. Even if your goods arrive intact, once general average is declared you owe a contribution — and until you pay it, you can't collect your cargo. With insurance, the insurer handles it on your behalf; uninsured, you get an unexpected bill directly.

2. Incoterms and Insurance Responsibility — The CIF Trap

The Incoterms we covered in #39 are decisive for insurance too. The trade term determines when risk passes from the seller to you, and who takes out the insurance. Mistake the term and you end up in the situation where "I thought the other side had insurance, but it was actually an uninsured leg."

CIF is where the misunderstanding runs deepest. "The C stands for Insurance's cousin — the seller surely bought good cover," is easy to assume, but there are two traps.

So in practice, even under CIF, importers specify ICC(A) cover in the contract (#12), or they simply buy on FOB terms and insure it themselves on terms they trust. This is why you have to manage "what cover" more than "who buys it."

3. The Basics of Cargo Insurance — ICC(A)/(B)/(C) and the Insured Amount

The cover scope of marine cargo insurance is divided by the internationally standard ICC (Institute Cargo Clauses). There are three grades — A, B, and C — with A the broadest and C the narrowest. You only need the concept.

Insured Amount — Why 110% of the Invoice Value

The amount you insure for is the insured amount. By convention it's set at 110% of the invoice value (CIF value). The 100% is the goods' value, and the extra 10% is a margin to roughly cover freight, duty, expected profit, and other costs already spent but unrecoverable when an accident occurs. In other words, on a total loss you're designed to recover not just the goods' price but some of the incidental costs lost in that transaction. You can adjust the ratio for special circumstances, but 110% is a safe starting point.

Premium Level — How Much Does It Cost

The premium rate varies by cargo type, packing, shipping route, and cover scope, but for ordinary consumer goods moving by sea it's often set in the 0.1–0.3% of insured amount range. For example, insure a shipment with an invoice value of KRW 20 million at 110% and the insured amount is KRW 22 million; apply 0.2% and the premium lands around KRW 44,000. You're transferring total-loss risk for a few hundredths of a percent of the goods' value, so from a total-cost perspective (#18) this isn't a line item to begrudge. The exact rate comes only after you provide the cargo details and get a quote.

4. Buying It in Practice — Where and How

Buying cargo insurance is simpler than you'd think. The real choice is picking, to match your shipping pattern, "through whom, and per-shipment or blanket."

Through the forwarder vs. direct with the insurer

The most common route is to ask the forwarder (#35) to arrange it together. The B/L and invoice details are already with the forwarder, so the process is fast, and for small shipments this is convenient. But you must get the policy and check directly that the cover isn't set to the minimum and that the insured amount is correct. If your shipments are large or frequent, contracting directly with an insurer or an insurance agency and tailoring the cover terms to your cargo is more advantageous.

Per-shipment (individual) vs. blanket (open cover)

Once importing becomes routine, open cover is the better fit. It eliminates at the source the accident of forgetting to insure and letting a ship sail uninsured, and as volume builds you gain room to negotiate the rate.

Documents you'll need

For both the purchase and any later claim, these documents should be organized as a set. Most overlap with your trade documents (#40).

• Commercial Invoice (CI) — the basis for the insured amount
• Packing List (PL) — quantity, weight, and packing details
• Bill of Lading (B/L) — the transport contract and cargo identification
• Insurance policy — issued after purchase; always verify the cover scope and insured amount

5. An Accident Happened — The Claim Procedure

Insurance is less about "having it" than about "getting paid properly when an accident hits." Mishandle the initial response and even a legitimate loss can't be proven, and you get pushed off the payout. Memorize the order.

6. What Cargo Insurance Does Not Cover — Don't Confuse Insurance with QC

Mistake cargo insurance for a cure-all and you fail to prepare where it actually matters. Cargo insurance covers "physical damage that occurs accidentally during transit." Everything outside that belongs to a different tool, not insurance.

• Loss from poor packing — Damage from flimsy packing unsuited to the cargo's nature is prone to being an exclusion. Packing is managed in the order specification (#15), not by insurance
• Loss from delay — A late ship that makes you miss a season or lose a sales window is, as a rule, not covered
• Market price drop — A loss from the market falling by the time of arrival is not an insurable event
• Defects & quality issues — Defects the factory made wrong in the first place are not transit losses. That's the territory of QC (#21), inspection (#47), and the contract (#12), not something cargo insurance fills
• Inherent nature & natural wastage — Ordinary loss in weight, changes arising from the material's own characteristics, and so on

7. Beyond Cargo Insurance — The Territory Trade Insurance (K-SURE) Fills

If cargo insurance handles "in-transit cargo loss," there's a separate system for the trade-transaction risks outside it: trade insurance, run by the Korea Trade Insurance Corporation (K-SURE). Many of its products are for exporters, but there are importer-relevant schemes too, so it's worth knowing the concept.

To sum up: goods breaking on the way is cargo insurance; sending money and getting no goods, or sending goods and getting no money is trade insurance territory. For most import sellers the first priority is cargo insurance, and where advance payments are large or you're handling big amounts with a new counterparty, you can review trade-insurance schemes alongside it. The specific eligibility and cover are finely segmented, so confirm with the relevant agency or an expert to get it right.

8. Cargo Insurance Checklist

Checkpoints stage by stage, from pre-purchase review to accident response.

Purchase Stage

• Confirmed who carries the transit risk under my Incoterm (FOB/EXW means my cover is mandatory)
• Verified from the policy whether CIF cover is set to the minimum (ICC(C))
• Specified cover matching the cargo's nature (mostly ICC(A))
• Set the insured amount at 110% of the invoice value
• Disclosed to the insurer whether the cargo needs endorsements (lithium batteries, dangerous goods)

Pre-Shipment Stage

• Completed the purchase so insurance is in force before the ship sails
• Reviewed open cover (floating policy) if importing is regular
• Organized the policy, CI, PL, and B/L as a set

Accident-Response Stage

• Inspected immediately on receipt and captured before/after in photos and video
• Notified the insurer, forwarder, and carrier of the accident within the deadline
• Preserved the damaged cargo instead of scrapping it at will
• Filed the claim with the survey report and claim documents accurately assembled

Closing — The Best Insurance Is the One You Never Use

Today's content, compressed one line each:

• Necessity: the transit stretch is a risk you can't control; carrier liability won't protect your cargo's value
• Incoterms: even under CIF the risk is yours and the cover may be minimum — "what cover" over "who buys it"
• Cover: most sourcing cargo is ICC(A), and 110% of the invoice value is the default insured amount
• Claim: photos, preservation, and notice right after receipt decide the payout
• Distinction: defect/quality loss is the territory of QC and the contract; payment risk is the territory of trade insurance

Cargo insurance is the kind you're best off never using. That's why it feels like a waste — but in international shipping, the "one time" comes eventually. Making sure that one time doesn't rock your business, by blocking the worst case for a few hundredths of your cargo's value — that's the whole of cargo insurance.
