Freight Ate the 10 Percent Cushion: Why CIF Plus 10 Under-Insures Indian Cargo

For most of the last decade an Indian exporter could treat ocean freight as a small tail on the invoice. A container of engineering goods worth USD 40,000 moved to Jebel Ali or Rotterdam for a few hundred dollars, so the difference between insuring invoice value and insuring true landed cost was inside the 10 percent margin that every marine policy adds by convention.

That arithmetic has moved. The Economic Times reported on 7 August 2026 that uncertainty around the Strait of Hormuz had pushed landed costs up by as much as 50 percent, with the resulting pressure feeding into consumer prices. The Times of India reported on 5 August 2026 that the global ocean freight spike driven by the West Asia conflict was hitting traders in Mangaluru directly, with importers and exporters absorbing the rate increases. The Loadstar had reported on 22 July 2026 that carriers were rolling out heavy surcharges into Indian trades specifically because demand there was running hot.

The insurance side moved with it. Rediff reported on 24 July 2026 that marine war risk premiums had risen by 200 percent on West Asia routings. India Shipping News, citing S&P Global on 29 July 2026, described Red Sea traffic slowing as security threats and insurance restrictions reshaped which vessels took which route, which is the mechanism that turns a war risk surcharge into a longer voyage and a detention bill as well.

Each of those numbers lands on the same place in the policy: the amount actually at risk at destination. Almost nothing in the Indian marine market has changed to reflect it.

Open the marine open cover wording and find the clause headed basis of valuation or insured value. In the standard Indian form it reads close to this:

The insured value shall be the invoice cost of the goods plus freight and insurance charges, plus 10 percent.

That is the CIF plus 10 formula. It is not a coverage clause and it is not a limit clause. It is the agreed measure of value that governs both the premium you pay and the amount you recover, because a marine cargo policy is a valued policy: once the parties agree a value, that value is conclusive between them for the purposes of the insurance.

Three consequences follow, and buyers routinely miss the third.

1. The insurer charges rate on that value, so an understated basis produces a pleasingly small premium.
2. A total loss pays that value, no more, whatever the goods actually cost to replace at destination.
3. A partial loss is settled by reference to that value against the insurable value, which is where the average clause enters.

The formula was designed when freight and insurance together were a modest slice of C, I and F, and the 10 percent margin absorbed the exporter's anticipated profit plus incidental expenses. It has no elasticity built into it for freight that triples inside a policy year.

Take a consignment with an ex works value of INR 40,00,000 moving from Nhava Sheva to a Gulf port.

In a normal freight market the exporter books ocean freight at INR 1,20,000, marine premium at roughly INR 12,000, and the CIF figure lands near INR 41,32,000. Add 10 percent and the insured value is about INR 45,45,000. Comfortable.

Now apply the conditions the July and August 2026 reporting describes. Ocean freight on the route rises with the carrier surcharges The Loadstar described. A war risk premium at 200 percent of its prior level is loaded on the voyage. The vessel reroutes, which adds sea days, and the box sits at a transhipment port long enough to accrue detention and demurrage. Suppose freight and voyage-related charges together reach INR 5,60,000 against the original INR 1,20,000.

The exporter has two habits available, and both fail.

• If the declaration is made on the original invoice terms, the insured value stays near INR 45,45,000 while the actual value of the goods delivered at destination is closer to INR 45,60,000 before the profit margin, and above INR 50,00,000 with it. The 10 percent cushion has been consumed entirely by freight.
• If the declaration picks up the new freight but the basis clause is still CIF plus 10, the cushion is restored on paper but the exporter has quietly bought a policy where more than 12 percent of the sum insured is freight that, on many Incoterms, is not even a loss the exporter suffers.

Both problems come from the same source. The basis clause was written to track invoice value, and the cost structure of the shipment no longer tracks invoice value.

Under Section 81 of the Marine Insurance Act, 1963, where the assured is insured for less than the insurable value, the assured is deemed to be their own insurer for the balance. That is the statutory footing for average, and it applies to partial losses, which are the great majority of marine cargo claims.

Work a partial loss through the example. Say seawater damage during a rerouted voyage writes off 30 percent of the consignment, and the surveyor assesses the loss at destination values, as surveyors do. Loss assessed: INR 15,00,000. Insured value declared: INR 45,45,000. Insurable value at destination once the actual freight, war risk surcharge and detention are counted: INR 55,00,000.

The recovery is reduced in the ratio of insured value to insurable value, roughly 82.6 percent, so the settlement lands near INR 12,40,000 against an assessed INR 15,00,000. The exporter carries INR 2,60,000, plus the deductible, on a policy that was in force, in date, and correctly declared under a clause nobody amended.

This is the failure mode worth internalising. Under-insurance from a freight spike does not announce itself at inception, at declaration, or at survey. It shows up once in the adjustment, at the end, when there is nothing left to fix.

The basis of valuation is an endorsable clause. It can be replaced mid-term without waiting for renewal, and in a volatile freight market it should be.

There are three bases an Indian insurer will normally entertain on a commercial open cover.

1. CIF plus 10. The default. Adequate only while freight and insurance stay a small share of the total.
2. Landed cost plus a stated margin. Invoice value plus all charges incurred to deliver the goods to the named destination, which picks up ocean freight, war risk surcharge, bunker and congestion surcharges, inland haulage, and where agreed, customs duty. This is the direct fix for the current market because the clause tracks the cost line that is actually moving.
3. Selling price or market value at destination. Invoice value replaced by the contracted resale price or an agreed formula tied to it. Underwriters price this more cautiously because it insures the exporter's margin as well as the goods, and they will usually want the sales contract or the price formula disclosed.

The endorsement mechanics are mundane and often done badly:

• Ask for the endorsement in writing, specifying the new clause text and the effective date. An oral confirmation from a servicing executive is not a change to the wording.
• Confirm whether the change applies to sendings that have already attached. Marine risk attaches when goods leave the warehouse, so a mid-term endorsement usually operates only on sendings attaching after the effective date unless the insurer agrees otherwise.
• Recheck the limit per sending and per bottom against the new, higher declared values. Raising the valuation basis without raising the limit per sending moves the shortfall from average to a hard cap.
• Expect an additional premium, since the rate now applies to a larger base. Compare it against the average deduction it removes rather than against last year's premium.
• Update the certificate template. Certificates issued from an old template will keep printing values on the old basis, and a certificate is what the bank and the buyer read.

Re-basing valuation is a different operation from re-basing turnover. If the volume of your shipments has also moved, that is a declaration problem, handled separately in our post on re-basing marine turnover declarations mid-term. A cover can be wrong on both axes at once, and fixing one does not touch the other.

Not every gap should be closed by rewriting the basis clause. Two named products exist precisely for the components that sit awkwardly inside a CIF calculation.

Duty insurance covers the customs duty paid or payable on imported goods that are lost or damaged. It matters because duty is assessed on the transaction value including freight and insurance, so a freight spike raises the duty bill on the same cargo. Where the importer has paid duty on goods that arrive damaged, the duty element is recoverable under a duty policy and not under the ordinary cargo cover, unless the basis clause was written to include it. Duty cover is normally rated lower than the main cargo rate and often carries its own average condition, so the duty sum insured has to track the actual assessable value rather than an old estimate.

Increased value cover insures the difference between the originally declared value and a higher true value on cargo already insured. It is the right instrument when the change is specific and after the fact:

• the contract price was revised upward after cover attached, common where pricing formulas track commodity indices
• the market value at destination has risen during a voyage that has been extended by rerouting
• a single high value sending has moved past the limit per sending and the insurer will write the excess as a specific declaration rather than amend the whole cover

The distinction is one of timing. Change the basis of valuation when the cost structure of all future shipments has shifted, which is what a sustained freight and war risk surcharge environment does. Use increased value when one voyage or one contract has moved and the rest of the book has not.

A war risk surcharge is a freight charge levied by the carrier, and it is separate from the war risk premium the cargo insurer charges under the Institute War Clauses. Both have moved, and the question of who insures which is decided by the Incoterm, not by who happened to pay the invoice.

FOB. Risk passes to the buyer on loading. The Indian seller insures only up to the ship's rail, and the buyer arranges cover for the voyage. If the buyer is paying freight, the carrier's war risk surcharge belongs in the buyer's insured value. An Indian exporter who adds the surcharge to an FOB declaration is insuring a cost that is not theirs, paying rate on it, and creating an overlap with the buyer's own policy.

CFR. The seller contracts and pays for carriage, including surcharges, but risk still passes on loading. This is the term that generates most confusion. The seller has the freight cost and the buyer has the risk, and the buyer arranges insurance. The seller's exposure to the surcharge is commercial rather than insurable, and it belongs in the price, not in a cargo declaration.

CIF. The seller contracts carriage and insurance and bears the cost, while risk passes on loading. Here the surcharge does belong inside the insured value, because the seller's own policy is the one that has to indemnify the buyer for the value at destination. Under CIF the seller's minimum obligation is Institute Cargo Clauses (C) at 110 percent of the contract price, which is exactly the formula this post is arguing has stopped being adequate. Sellers who wish to protect the buyer properly in this market should agree an upgraded basis in the sale contract rather than relying on the Incoterms minimum.

To avoid a double insurance dispute:

• State in the sale contract which party insures, on what clauses, and on what valuation basis. Incoterms allocates cost and risk; it does not settle valuation.
• Where both sides carry cover, disclose each policy to the other insurer. Undisclosed double insurance invites a contribution argument that delays settlement even when the loss itself is uncontested.
• Keep the carrier's surcharge invoice on file. Adjusters will ask for evidence that a claimed freight element was actually incurred by the claiming party.
• If the routing itself is the exposure, check the vessel quality conditions as well. Our post on vessel classification clauses on Hormuz routings covers how a rerouted or substandard bottom can defeat cover before valuation ever becomes relevant.

Valuation basis is not a renewal-time decision when the underlying costs move quarterly. A workable cadence for an Indian exporter or importer with a live open cover:

1. Monthly. Compare actual all-in landed cost per shipment against the declared insured value on the same shipment. The ratio is the number that matters. Once landed cost exceeds roughly 95 percent of declared value, the 10 percent cushion is gone.
2. On any surcharge announcement. Carrier surcharges arrive with notice periods. Treat the notice as the trigger to recheck the basis, not the first invoice that carries it.
3. On a routing change. A diversion adds sea days, transhipment handling and detention exposure. All three enter landed cost and none of them appear on the commercial invoice.
4. Quarterly with the insurer. Bring the ratio to the servicing team and ask directly whether the current basis of valuation still reflects value at destination. Record the answer.
5. At every claim. Ask the surveyor which value they assessed the loss at. If the answer is destination market value while your policy declares invoice CIF plus 10, you have found the gap before it costs you a second time.

None of this is expensive. The additional premium on a landed cost basis is charged on the incremental value only. The alternative is a proportionate reduction on every partial loss for as long as the freight cycle lasts, which is the more expensive way to discover that a clause written for a different market is still in your marine policy.
