1 Overview
Cargo insurance is not a single obligation that travels automatically with a shipment. It is a private contract between an insured party and an insurer, and it sits alongside the sale contract and the contract of carriage. The Incoterm chosen by the buyer and seller decides where risk passes and who is obliged to arrange cover. Only two Incoterms create a legal duty to insure: CIF and CIP. Under every other rule, including FCA, FOB, CFR, DAP, and DDP, neither side is obliged to buy insurance. That does not mean insurance is unnecessary. It means the decision belongs to whichever party carries the risk at each stage of the journey.
Because risk and cost can pass at different points, a shipment may be uninsured even though one party believes the other has arranged cover. A buyer who assumes the seller has insured under CFR may discover after a loss that the seller had no obligation to do so. A seller who delivers under DAP may carry risk to the destination but still have no contractual duty to insure. The practical answer is to read the Incoterm, identify who bears risk on each leg, and confirm in writing who is buying cover, for what value, and with what exclusions.
This article explains how risk transfer, cost allocation, and insurance obligations interact under the main Incoterms used in air and sea freight. It then walks through the documents that carry those obligations and the errors that most often leave a shipment exposed.
2 Where the risk and the cost actually land
Risk transfer and cost allocation are separate questions. Under FCA, the seller delivers the goods to the carrier nominated by the buyer, and risk passes at that point. The buyer pays the main carriage and any insurance. Under FOB, risk passes when the goods are on board the vessel, and the buyer again arranges and pays for the main carriage and insurance. Under CFR, the seller pays the main freight to the destination port, but risk still passes when the goods are on board at origin. That gap is important: the seller pays freight, yet the buyer bears risk during the sea voyage and should consider its own insurance.
CIF and CIP are the two rules that reverse the insurance obligation. Under CIF, the seller must arrange minimum cover, typically Institute Cargo Clauses (C), and pay the premium. Under CIP, the seller must arrange broader cover, typically Institute Cargo Clauses (A), unless the parties agree otherwise. In both cases, risk passes at the same point as the corresponding non-insurance rule: on board for CIF, and at delivery to the carrier for CIP. The seller's insurance obligation exists to protect the buyer, who bears risk after that point.
Under DAP, the seller bears risk until the goods are delivered to the named destination, ready for unloading. Under DDP, the seller bears risk to the same point and also pays import duty. Neither DAP nor DDP obliges the seller to insure, but a seller carrying risk across an ocean or through an airport hub has a strong commercial reason to do so. The buyer, meanwhile, may have little or no risk after delivery and may not need separate cover.
3 How the mechanics work end to end
The mechanics begin with the sale contract. The parties choose an Incoterm, and that choice determines the delivery point, the cost split, and the insurance default. If the term is CIF or CIP, the seller must obtain a cargo insurance policy or certificate and pass it to the buyer. The policy should name the buyer as insured or assign the benefit, cover the agreed value, and remain valid until the destination named in the rule. If the term is anything else, the parties should state in the contract who will insure, for what amount, and against which risks. Silence leaves each side to insure its own exposure, which can produce gaps.
Next comes the contract of carriage. The freight forwarder or carrier issues a bill of lading, air waybill, or sea waybill. That document shows the port or airport of loading and discharge, the consignee, and the freight terms. It does not by itself prove insurance. Insurance is evidenced separately by a certificate or policy. When a letter of credit is involved, the bank will usually require an insurance document in a specified form and amount, often 110 percent of the invoice value, and will reject a certificate that does not match the credit terms.
At the border, the customs declaration and the accompanying invoice, packing list, and transport document determine duty and taxes. Insurance cost is part of the customs value in many jurisdictions, so the premium can affect the duty base. A buyer who arranges insurance separately should keep the premium evidence, because customs may ask for it. The end-to-end chain is therefore sale contract, carriage contract, insurance contract, and customs declaration, each with its own documents and each capable of creating or closing a risk gap.
4 A worked example from door to destination
Suppose a buyer in Europe purchases machinery from a seller in Asia. The parties agree on CIF Rotterdam. The seller books sea freight, pays the main carriage, and arranges minimum cover under Institute Cargo Clauses (C). Risk passes when the goods are on board at the port of loading. The seller sends the buyer a bill of lading, an insurance certificate, a commercial invoice, and a packing list. The buyer pays import duty and takes delivery at Rotterdam. If the vessel encounters heavy weather and the machinery is damaged, the buyer claims under the seller's insurance certificate, because risk passed at loading and the seller's policy was arranged for the buyer's benefit.
Now suppose the same parties instead agree on CFR Rotterdam. The seller still pays the main freight, but there is no insurance obligation. Risk passes on board at loading, so the buyer bears the sea risk. If the buyer assumes the seller has insured, and the cargo is lost, the buyer has no policy to claim under. The buyer should have purchased its own cover from the loading port to Rotterdam. The freight invoice does not include insurance, and the bill of lading does not prove it.
Finally, suppose the parties agree on CIP by air to a European airport. The seller must arrange broader cover, typically Institute Cargo Clauses (A), and pay the premium. Risk passes when the goods are handed to the air carrier. The seller provides an air waybill and an insurance certificate. The buyer clears customs and pays duty. If the cargo is damaged in transit, the buyer claims under the seller's policy. In each case, the Incoterm, not the freight invoice, decides who insures and who claims.
5 Mistakes that cost money at the border
The most common mistake is assuming that the party paying freight also bears risk and insures. Under CFR and CIF, the seller pays freight, but under CFR the buyer bears risk and has no insurance obligation from the seller. Under CIF, the seller insures, but only at minimum cover. A buyer who needs all-risks protection must negotiate CIP or buy additional cover. Another frequent error is relying on a carrier's liability, which is limited by convention and typically far below the cargo's commercial value. Carrier liability is not cargo insurance.
A second mistake is insuring for the wrong value. Policies are often written for 110 percent of the invoice value, but if the buyer has paid freight and duty, the true loss may be higher. Under CIF and CIP, the seller's obligation is to insure at 110 percent of the contract price, but the buyer may need more. A third mistake is letting cover expire before the destination. A policy that ends at the port of discharge may not cover onward inland transit, storage, or delivery to the final warehouse. The Incoterm's delivery point should match the policy's termination point.
A fourth mistake is ignoring exclusions. Standard cargo clauses exclude inherent vice, inadequate packing, delay, and ordinary leakage. A shipment of hygroscopic cargo or fragile goods may need specific cover. Finally, failing to document the insurance arrangement in the sale contract leaves each side guessing. The contract should name the insured, the beneficiary, the cover, the value, and the period. At the border, customs may also question the declared value if insurance and freight are not properly shown.
6 Documents worth keeping
The commercial invoice is the starting document. It states the goods, the value, the Incoterm, and often the insurance and freight charges separately. Customs uses it to assess duty, and insurers use it to set the insured value. The packing list supports the invoice by describing how the goods are packed, which matters for both damage claims and customs inspection. The transport document, whether a bill of lading, sea waybill, or air waybill, proves the contract of carriage and shows the ports or airports and the consignee. It does not prove insurance, but it establishes where risk passed under the Incoterm.
The insurance certificate or policy is the key document for a claim. It should show the insured party, the beneficiary, the cover clauses, the insured value, the voyage, and the expiry. Under CIF and CIP, the seller must provide it to the buyer. Under other terms, whichever party buys cover should keep the original and provide a copy to the other if required by the sale contract or letter of credit. A certificate that names the wrong beneficiary or covers the wrong voyage can be rejected by a bank and can complicate a claim.
The customs declaration and duty payment evidence complete the set. They show the declared value, the tariff classification, and the taxes paid. Because insurance and freight can form part of the customs value, keeping the premium invoice and freight invoice helps justify the declaration if customs audits the entry. Together, these documents allow either party to prove what was shipped, who bore risk, who insured, and what was paid at the border.
7 Frequently asked questions
Does every shipment need cargo insurance? No. Insurance is a commercial decision unless the Incoterm is CIF or CIP, which oblige the seller to arrange cover. Under FCA, FOB, CFR, DAP, and DDP, neither party is obliged, but the party bearing risk should consider whether the exposure justifies the premium. High-value, fragile, or perishable goods usually warrant cover even when it is not required.
Who insures under CIF and CIP? The seller arranges and pays for the insurance. Under CIF, the default is minimum cover, typically Institute Cargo Clauses (C). Under CIP, the default is broader cover, typically Institute Cargo Clauses (A). The buyer is the beneficiary and can claim under the policy after risk passes. The parties can agree to different cover, but they must say so in the contract.
What happens if the seller pays freight but does not insure? Under CFR, the seller pays the main freight but risk passes on board at origin. The buyer bears the sea risk and has no insurance from the seller. The buyer should arrange its own cover from the loading port. Under CIF, the seller pays freight and insures, so the buyer is protected at the minimum level.
Can a buyer rely on the carrier's liability? No. Carrier liability is limited by international conventions and is usually much lower than the cargo's commercial value. It is not a substitute for cargo insurance. A buyer who wants full protection should buy a policy that covers the full voyage and the declared value.
How much insurance should be arranged? A common commercial practice is 110 percent of the invoice value, which covers the goods and a margin for freight, duty, and incidental costs. The exact figure should be stated in the sale contract. Under CIF and CIP, the seller's minimum obligation is 110 percent of the contract price, but the buyer may need more if freight and duty are significant.
