When Your Customer Floods: The Offtake Loss No Supplier's BI Policy Sees

Autocar India reported on 29 July 2026 that Tata Motors halted production at its Sanand plants because of the Gujarat floods, and NDTV carried the same suspension the same day. Business Today reported on 28 July 2026 that the monsoon floods across Assam and Gujarat had affected over 5.24 lakh people, with dozens dead and the Army leading rescues. This was not a single-plant incident. scanx.trade reported on 3 August 2026 that DCW Limited suspended operations at its Dhrangadhra facility because of severe flooding, which puts a second listed manufacturer out of production in the same event.

For the plant owner, the insurance question is ordinary. Water entered an insured location, there is material damage to building, plant and stock, and the fire policy plus the business interruption section respond in the usual way.

For the Tier-1 and Tier-2 component suppliers feeding that plant, nothing happened at all in insurance terms. Their sheds are dry. Their machines run. Their stock is intact. What stopped is the schedule, and with it the offtake. A pressings supplier in the Sanand belt, a wiring harness unit in Vithalapur, a plastics moulder on the Ahmedabad-Viramgam corridor: each one holds a fire and BI policy that will pay nothing, because the BI section of an Indian fire policy is triggered by damage at the insured's own premises to property insured under the material damage section.

The loss lands in the same quarter. Fixed costs continue, contract labour has to be retained or paid off, working capital sits in finished goods nobody will take delivery of, and the shortfall in gross profit is measured in weeks of lost turnover. The only thing that turns that into an insurance recovery is an extension the supplier bought before the flood.

Almost every conversation an Indian broker has about contingent business interruption runs in one direction: what happens to my production when my supplier stops. That is the supplier extension, and the corpus covers it in detail in Contingent Business Interruption Claims in India and in Contingent Business Interruption Cover for Indian Corporates 2026. Both look upstream, at input failure.

Sanand is the other direction. The dependency that failed here is downstream. The supplier's inputs are fine and its plant is fine. Its customer, the single OEM that consumes most of its output, has stopped buying.

The market names this the customers extension, sometimes written as the customers premises extension or the customers and suppliers extension when one wording covers both legs. It sits in the BI section as an extension of the definition of the incident, so that damage at a named or described customer's premises is treated as if it were damage at the insured's own premises for the purpose of triggering the loss of gross profit calculation.

Indian manufacturers with concentrated customers have historically treated offtake risk as a commercial problem, handled through contracts and diversification. That works until the customer's plant floods.

This is the first question a supplier CFO should put to the broker, and it usually decides the size of the answer before anything else does.

Named customer basis. The extension schedules the customer by legal entity and, in the better wordings, by specific premises. Limits are meaningful, often a stated percentage of the BI sum insured or a standalone figure. Underwriters price it because they can see the accumulation. If Tata Motors and the Sanand premises are named on your schedule, you have a claim to build.

Unnamed customer basis. The extension covers damage at the premises of any customer, without naming. Limits are small, frequently a low single-digit percentage of the BI sum insured or a fixed sub-limit that has not been reviewed in years. Underwriters price it as a nuisance grant because they cannot model the exposure. A supplier with INR 40 crore of annual gross profit riding on one OEM and an unnamed sub-limit of INR 1 crore has bought a rounding error.

Direct customer only, or the chain? Tier-2 suppliers feed Tier-1s, not the OEM. If the flooded premises belong to the OEM and your contractual customer is the Tier-1, an extension worded around "premises of your customers" may not reach one link further up. Some wordings extend to customers of customers, most do not without an endorsement.

Three checks to run on the schedule this week:

1. Find every extension in the BI section that references premises other than your own, and note whether each points upstream, downstream, or both.
2. For each downstream extension, divide the sub-limit by your monthly gross profit. That quotient is how many weeks of protection you hold.
3. Check whether the sub-limit sits inside the BI sum insured or on top of it, and whether it is per event or in the aggregate for the policy year.

Standard customers extensions are damage-triggered. The wording requires physical loss or damage at the customer's premises, caused by a peril that would have been insured under the supplier's own material damage section had the property been the supplier's. Two consequences follow, and both matter in a flood event.

First, the peril has to line up. If the supplier's own fire policy excludes flood, or carries flood only as a named add-on that was not taken, then flood damage at the customer's premises does not trigger the extension even though the customer's own policy paid. The test is the supplier's insured perils, applied notionally to the customer's property. Suppliers in Gujarat who trimmed the flood add-on to save premium have removed the trigger for their own downstream cover.

Second, damage is required, not disruption. If the OEM had suspended production because the approach roads were under water, or because employees could not reach the plant, or because a district administration order closed industrial units, and the plant itself was dry, a damage-triggered extension does not respond. The Sanand suspension reported on 29 July sits in a flood event where physical water ingress at plant premises is plausible, but plausible is not evidenced. The supplier has to establish, through the customer, that insured-type damage occurred at the scheduled premises.

That evidentiary burden is the practical problem. Your customer is in the middle of its own large property loss, owes you nothing by way of claim documentation, and its legal team will not casually hand a supplier a statement about damage at its plants.

What to ask the customer for, in writing, early, and through the commercial relationship rather than through your insurer:

• A dated confirmation that production was suspended, the premises affected, and the resumption date.
• Confirmation that the suspension followed physical damage or water ingress at the premises, without asking for quantum.
• The purchase order or schedule amendments that cancelled or deferred your deliveries, which is your own primary evidence regardless.

Ask for interruption-triggered wording at renewal, sometimes sold as a non-damage denial of access or a customer suspension extension. It costs more and carries tighter sub-limits, and it is the only version that responds when the customer's plant stops for a reason other than damage to its own property.

Suppliers consistently underestimate this. The OEM restarts, and the supplier assumes the loss ends on the restart date. It does not.

An automotive line coming back after a flood does not resume at full rate. The OEM works through its own damaged stock, re-qualifies wet or suspect components, and re-sequences the build plan. Call-offs return in steps over several weeks, and the supplier also carries the cost of the pipeline it built and could not ship, plus overtime and expedited freight once the schedule accelerates again.

The indemnity period in the loss of profits section is what decides whether any of that is recoverable. Three features to check:

1. Length. Many mid-market Indian manufacturing BI placements still run a 6 or 12 month indemnity period on the main section, but apply a shorter capped period to the contingent extensions, sometimes 30 or 60 days. A 30-day cap on a customers extension covers the shutdown window and nothing after it.
2. Start and end. The period should run from the date of damage at the customer's premises until the supplier's results are no longer affected, subject to the maximum. Wordings that end the period on the customer's resumption of production cut off the ramp entirely, which is exactly the part where the loss accumulates.
3. Increased cost of working. Check whether the extension carries ICOW and additional ICOW, or only gross profit. Expedited freight to recover a schedule, temporary storage for finished goods you could not ship, and labour retained through the gap are ICOW items. Without the grant they are absorbed.

The Times of India reported on 1 August 2026 that the Cabinet approved a move to fast-track insurance claims for flood-affected parties. A faster settlement environment helps a supplier only where the extension responds at all. Speed does not create a trigger, and it does not lengthen an indemnity period.

In a damage claim at your own plant, output stops for a visible physical reason and the loss is measured against what the plant would have produced. In a customers extension claim, the machines could have run. The measurement question is what turnover would have occurred but for the customer's shutdown, and the insurer will test every assumption in that counterfactual.

The standard Indian gross profit formula applies: turnover shortfall multiplied by the rate of gross profit, plus increased cost of working, less savings in insured standing charges. The contest is in the inputs.

Establishing the but-for turnover. Firm purchase orders and released call-off schedules covering the interruption weeks are the strongest evidence. Rolling forecasts are weaker but usable. A supplier who works to weekly call-offs against an annual nomination has a documented expectation; a supplier working on spot orders has an argument.

Deferred versus lost turnover. This is where most of the money moves. If the OEM catches up and takes the same annual volume, the insurer will argue the turnover was deferred, not lost, and that the shortfall reverses inside the indemnity period. The counter-arguments are specific and have to be evidenced at the time: capacity constraints that prevent recovery of the volume, seasonal model-year cutoffs, variants discontinued during the shutdown, and volume permanently reallocated to another supplier. Track these while the interruption is running, because reconstructing them nine months later is difficult.

Savings in standing charges. Power, consumables, contract labour that was released, and freight not incurred all reduce the claim, and the insurer's accountant will find them. Producing the savings schedule yourself is better than having it produced for you.

Uninsured working expenses. Check which cost lines the policy wording treats as variable in the gross profit definition. If the definition deducts power and contract labour as well as purchases, your rate of gross profit is lower than your accounting gross margin and the sum insured should have been set on the policy definition rather than the P&L line.

Mitigation. The duty to minimise applies. Short-time working, redeploying capacity to other customers, and holding rather than scrapping in-process stock need to be documented as decisions taken during the interruption, with dates.

The fortnight after the customer stops

1. Notify the insurer in writing even if you doubt the extension responds. Late notification is a defence you can hand the insurer at no cost to them. Describe the customer, the premises, the suspension date, and your dependency.
2. Freeze the evidence of expectation: the last released call-off schedules before the suspension, open purchase orders, the nomination letter or long-term agreement, and the delivery history for the preceding twelve months.
3. Open a cost-capture code in the ledger on the suspension date. Every rupee of expedited freight, temporary storage, retained idle labour and rework after restart goes to that code from day one.
4. Write to the customer for a dated suspension and resumption confirmation. Route it through purchasing or the plant SQA contact, not through legal.
5. Count and photograph finished goods and work in process built against the cancelled schedule, and record any material with a shelf life or a model-year cutoff.
6. Instruct your broker to give you four facts in writing: the extension wording, the sub-limit, the aggregate treatment and the indemnity period cap.

At renewal

The Sanand event is the argument. A supplier with a single OEM taking a large share of turnover should be pricing a named customers extension with a sub-limit set against months of gross profit rather than a token figure, an indemnity period on the extension that matches the main section, ICOW included, and the flood peril present on the material damage section so the notional peril test is satisfied.

The Gujarat property market is already absorbing the direct losses from this monsoon, covered in Gujarat's Rs 5,000 Crore Flood Claim Estimate. Capacity for downstream contingent extensions will not be cheaper after the event than it was before it, and the suppliers who ask for it now will at least be asking with a documented loss behind the request.
