When Freight Doubles, Your Declared Value Is Wrong: Re-Basing CIF Sums Insured Before the Festive Peak

Container capacity stranded by port congestion reached a record 4.31 million TEU in late August 2026, above the 4 million TEU peak of 2022, on reporting by Maritime Executive and Port Technology International. The Platts Container Index reached USD 7,565 per FEU on 21 August 2026, its highest level of the year. FreightWaves put Asia to US West Coast spot rates at USD 7,621 per FEU and Asia to US East Coast at USD 9,791 per FEU in the same month. For Indian shippers, trade reporting at the end of August described ocean freight to the United States reaching USD 10,000 per 40-foot container on vessel shortages and redeployments.

Freightos attributed the trans-Pacific strength to carrier capacity cuts and severe congestion at major Chinese ports rather than to demand alone. India picks the problem up through a second channel: a container crunch at Singapore and Colombo has disrupted Indian export supply chains, with a shortage of feeder vessels connecting Indian ports to those transhipment hubs identified as the root cause, and bottlenecks reported at Cochin, Tuticorin and Chennai alongside Mumbai, JNPT and Mundra.

Most of the commentary reads this as a cost and scheduling problem for the logistics team. It is also an insurance problem, because on a CIF or CIP sale the freight sits inside the number the exporter declares to its marine insurer. A marine open cover carrying a freight loading agreed when trans-Pacific rates were half of today's is declaring less than the cargo is worth on the quay at destination. Nothing in the monthly declaration routine flags that, and the shortfall surfaces at a survey.

Marine cargo is conventionally insured at CIF plus 10 per cent: the cost of the goods, the insurance premium, the freight to the named destination, and a customary uplift for the profit the consignee expected on arrival. Three of those four components are stable across a policy year. Freight is the one that moves.

The contractual floor comes from the Incoterms rules. Under Incoterms 2020, a CIF seller must obtain cover complying at minimum with Institute Cargo Clauses (C) and a CIP seller with Institute Cargo Clauses (A), in both cases for at least 110 per cent of the contract price, in the currency of the contract, from the named delivery point to the named destination. Where a documentary credit is silent on the insured amount, UCP 600 article 28(f)(ii) sets the same floor. Our guide to Incoterms and marine insurance responsibility sets out which party owes the cover on each term.

A freight spike splits that single number in two, and the split is where exporters get caught.

• On new business, the CIF price quoted to the buyer already carries today's freight, so 110 per cent of the contract price rises with the market and the contractual floor moves on its own.
• On business booked earlier at a fixed CIF price, the contract price is stuck at the old freight assumption while the exporter pays the new rate out of margin. It now understates what it costs to place the goods at destination, so 110 per cent of it falls short of the cargo's real arrived value.

The sum insured on an open cover declaration should track the second number, the money actually sunk into getting the consignment to the destination, and not merely the contractual minimum the buyer can insist on.

Take a 40-foot container of engineering goods, FOB Nhava Sheva at USD 80,000, moving to the US East Coast, on an open cover whose declaration formula was built at renewal around a freight assumption of USD 3,500 per FEU, with premium of about USD 100.

1. Declared value on the old basis: 80,000 plus 3,500 plus 100, giving a CIF of USD 83,600, uplifted by 10 per cent to USD 91,960.
2. Correct declared value at the August 2026 rate of USD 9,791: a CIF of USD 89,891, uplifted to USD 98,880.
3. The declaration therefore stands at about 93 per cent of the value it should carry, a shortfall of roughly USD 6,900 per container.

The shortfall scales inversely with value density, which is where the exposure concentrates. On a container of pharmaceuticals or electronics worth USD 900,000 FOB, a USD 6,300 freight movement is under one per cent of the insured value and needs no action. On a container of ceramic tiles, cotton yarn, rice or processed food at USD 25,000 FOB, the old basis declares 25,000 plus 3,500 uplifted to USD 31,350 against a correct value of 25,000 plus 9,791 uplifted to USD 38,270. The declaration covers about 82 per cent of what it should, and the freight line is now larger than a third of the goods value.

One blended freight factor across lanes fails for a second reason. Asia to US West Coast at USD 7,621 and Asia to US East Coast at USD 9,791 differ by about 28 per cent on the same continent, so an exporter shipping to both coasts on one average loading over-declares one lane and under-declares the other. Only the under-declared side costs money at claim time.

The customary 10 per cent is often treated as slack in the number, headroom that will absorb whatever the declaration got wrong. It does no such job. The uplift represents anticipated or imaginary profit: the margin the consignee loses when goods sold on are never delivered, plus the incidental cost of arranging a replacement. It is a distinct head of loss, expressed as a percentage of the CIF base.

A percentage applied to an understated base is understated in the same proportion. In the tile example, the entire 10 per cent uplift on the old basis is USD 2,850 while the freight gap alone is USD 6,291. Raising the uplift does not rescue the position either: 15 per cent over the old CIF gives USD 32,775 against a correct value of USD 38,270, still short by 14 per cent, and uplifts above the customary 10 per cent invite underwriter questions about whether the assured can evidence the profit it is insuring.

Where actual freight cannot be computed before dispatch, because peak season, congestion and equipment imbalance surcharges are levied after the bill of lading, agree a monthly true-up declaration so the difference is picked up while the goods are in transit and before any loss is known.

Increased value cover insures the difference between the value originally declared on a consignment and its true value at destination, written either as a further declaration under the same open cover or as a separate policy on the same voyage. Clause 14 of the Institute Cargo Clauses (A) 1/1/2009, headed Increased Value, sets out how the two interact: the agreed value of the cargo is deemed increased to the total insured under the primary policy and all increased value insurances together, and each insurer bears its proportion of the loss.

Increased value cover is the right instrument for a value movement on a specific voyage:

• A congestion surcharge, peak season surcharge or emergency rate restoration levied by the carrier after the consignment was declared, which raises the freight actually paid above the freight in the declaration.
• A contract price revised upward under an escalation formula after cover attached, common in metals-linked engineering goods and chemicals.
• A single high-value sending accepted specifically above the open cover's limit per sending, where the excess is easier to write as a separate declaration than by amending the whole cover.

It is the wrong instrument for a systematic mis-basing. If every lane's freight assumption is half of the market rate, papering each shipment with an increased value declaration produces ad hoc rating, a pile of endorsements, and an insurer who reasonably asks why the base declaration was never corrected once the freight market was public knowledge. Correct the formula, and keep increased value cover for genuine single-voyage movements. In either case the timing rule is absolute: cover must be effected before the assured knows of a loss, and a casualty or a report of a missing container closes the window on that consignment.

Section 81 of the Marine Insurance Act, 1963 states that where the assured is insured for less than the insurable value, or on a valued policy for less than the policy valuation, the assured is deemed its own insurer for the uninsured balance. That is the average clause in statutory form, and it turns under-declaration into compulsory self-insurance of the gap on partial losses.

Most Indian marine cargo policies are valued policies, where the practical effect is blunter. The insurer pays the agreed value on a total loss and no more, so an exporter who has paid USD 9,791 of prepaid, non-refundable freight recovers a value computed on USD 3,500.

General average makes it worse on a congested voyage

Congestion, forced discharge and stretched routings raise the odds of a casualty that ends in a general average declaration. Contributions are assessed on the contributory value of the cargo where the adventure ends, which reflects real arrived value including freight. Under the general average provisions of the Marine Insurance Act, 1963, where cargo is not insured for its full contributory value the recovery of that contribution from insurers is reduced in proportion to the under-insurance. An exporter under-declared by 18 per cent contributes on the full arrived value to the adjuster and recovers about 82 per cent of it from the cargo policy.

The safety valve is honesty. The floating policy provisions of the Act allow an erroneous declaration to be rectified even after loss or arrival, provided it was made in good faith. An assumption overtaken by a market move is the case that rule was written for. A freight factor left untouched for months after the trade press reported rates at two-year highs is a harder story to tell, which is why the endorsement should be dated now.

The correction is an endorsement rather than a renewal exercise, and insurers generally accept it without argument because an upward revision brings premium against exposure they already carry. A working sequence:

1. Pull 60 days of freight invoices by lane. Record the all-in cost per FEU including surcharges, then express it as a percentage of FOB value for each lane and product family. The spread between lanes is the point of the exercise.
2. Replace the fixed freight assumption in the declaration formula with actual freight and insurance paid per consignment, by endorsement, effective from a stated date. Record that the change is prospective, because it does not repair a shipment that already sailed under-declared.
3. Re-size the limit per sending. The same physical container now carries a higher declared value, so a limit fixed in rupees absorbs fewer boxes. A consolidation that sat inside the limit in April can breach it in September on freight alone.
4. Re-check accumulation limits at congested nodes. Longer dwell at CFS, ICD and transhipment terminals raises peak accumulation at constant volume, and the Singapore and Colombo bottlenecks hold more of your cargo in one place than the limits were sized for. The same discipline applied to volume growth is set out in our note on re-basing marine turnover declarations mid-term.
5. Update the certificate templates the bank sees. Where a documentary credit requires insurance for 110 per cent of CIF, a certificate of insurance issued on the old freight basis can fall short of the required amount and be drawn as a discrepancy, delaying payment on a shipment that is already late.
6. Pay the additional premium and keep the workings. Rating runs on declared value, so a higher freight line raises premium in direct proportion. The file note showing which freight data the revision used is what makes the good faith position provable later.

Declarations covering the festive and year-end peak are being made now, and every one on the old formula is another consignment that will need explaining if it does not arrive.

The same congestion that raised the freight line lengthens the time the goods spend in the system, and that reaches two policies at once.

On the cargo side, the transit clause holds up better than exporters fear. Clause 8.3 of the Institute Cargo Clauses (A) 1/1/2009 keeps the insurance in force during delay beyond the control of the assured, deviation, forced discharge, reshipment or transhipment, and cargo held at Singapore or Colombo for want of feeder space sits squarely within that wording. The limit that bites is the 60-day cap in clause 8.1, which ends cover 60 days after discharge overside at the final port of discharge if the goods have not reached the named destination by then. A feeder-starved final leg is where that clock runs out. Where the delay is foreseeable, ask the insurer for a duration extension in writing before the 60 days expire.

On the receivables side, the exporter has extended more credit than it agreed to. Where sale terms run a fixed number of days from bill of lading date, a transit that stretches by three weeks hands the buyer goods with three fewer weeks of credit left to run, and payment slips. Trade credit policies are written around a maximum credit period per buyer and a defined window for reporting overdues, so a payment that drifts past the insured period without an approved extension can fall outside cover, and a default reported late can be declined on notification grounds even when the debt is good. The comparison between ECGC and commercial trade credit insurance sets out where those limits sit in each product.

Run the two reviews together. When the freight desk hands over lane data for the declaration re-base, ask for the change in average transit days per lane: the first number fixes the sum insured, the second tells credit control which buyers need an extension approved before the invoice ages past the insured period.
