Ex-warehouse price
Also written Ex-warehouse prices
The spot price quoted for a commodity as it sits in the warehouse, ready for pickup — including Mandi Cess but excluding GST, and the basis on which agricultural spot polling prices are collected.
In plain language
When exchanges poll traders for a commodity's spot price, that price has to mean the same thing to everyone quoting it. Otherwise a price that includes transport to a buyer's factory would not compare fairly with a price for the same goods sitting untouched in a warehouse.
An ex-warehouse price fixes that meeting point: it is the price for goods as they stand in the warehouse, before any onward transport or handling beyond that point.
How it works
Because agricultural spot markets operate across many mandis with many participants, polling can throw up multiple, differently-structured price quotations for the same product. The workbook resolves this by defining the polled figures as ex-warehouse prices, which are inclusive of Mandi Cess but exclusive of GST.
This is the raw input that then goes through bootstrapping to remove outliers, before becoming the day's declared spot polling price — which in turn feeds into the Final Settlement Price of futures and options contracts.
A worked example
A chana trader in Madhya Pradesh quotes his product at "Rs 5,400 per quintal, ex-warehouse." That figure already has the local Mandi Cess baked in — the state levy charged on produce entering the mandi system — but it has not added GST.
A buyer working out the actual landed cost of that chana must separately add applicable GST on top of the Rs 5,400 quoted, and any freight to move the goods out of the warehouse to its own premises. If the polling panel instead reported some quotes GST-inclusive and others GST-exclusive, the exchange's spot price and any futures price built on it would be internally inconsistent — which is exactly why the ex-warehouse definition standardises what is, and is not, included.
Why NISM asks about it
Chapter 3, section 3.10, defines ex-warehouse pricing in the same paragraph as bootstrapping, as the standardisation that makes multiple polled quotes comparable. Expect a question testing what an ex-warehouse price includes and excludes — Mandi Cess in, GST out.
Common exam traps
- Mandi Cess is included; GST is excluded. This is the single fact most likely to be tested and most likely to be reversed by a guessing candidate.
- Ex-warehouse pricing applies specifically to agricultural spot polling, where multiple mandi-based quotations are common — it is not a general rule for every commodity's Final Settlement Price.
- GST is added separately at the point of billing for delivery, calculated on the Final Settlement Price — it does not disappear, it is simply not part of the polled ex-warehouse figure itself.

Answer: (d) Mandi cess
The distinction between mandi tax (subsumed) and mandi cess (not subsumed) is the kind of fine line that exam papers are built on — and it is easy to lose because the two names differ by one word.
The reason mandi cess survives connects back to the regulatory chapter: spot trade in agricultural commodities is a State List subject under Schedule VII. The mandi is a State institution operating under State law, and a cess levied for its upkeep sits outside the GST settlement between Centre and States. It is the same constitutional line that keeps SEBI out of the mandi.
And it has a practical consequence in this syllabus: polled agricultural spot prices are "EX-WAREHOUSE PRICES INCLUSIVE OF MANDI CESS BUT EXCLUSIVE OF GST" — precisely because the two are separate levies, one inside the GST net and one outside it.
The other survivor is customs duty, which is likewise outside GST — relevant for imported commodities where the landed cost carries a duty that no GST credit will recover.
Where GST does bite in this market: at delivery, levied "BY SELLER OF GOODS ON BUYER OF GOODS AT THE TIME OF BILLING", on "the FINAL SETTLEMENT PRICE of the goods to be delivered" — and separately on brokerage and exchange trading or clearing fees.

- BootstrappingThe statistical method exchanges use to clean spot price polling data — removing outlier quotes and repeatedly testing random selections until the final polled price has the least standard deviation against the full set.
- Commodity Transaction TaxA transaction tax on non-agricultural commodity derivatives — 0.01% on the sale of a futures contract, paid by the seller, with separate rates for options.
- Empanelled polling participantsThe traders and commodity users an exchange formally registers to report spot prices from centres across the country, feeding the daily spot price polling process that underpins futures and final settlement pricing.
- Spot price pollingThe statistical process by which an exchange collects physical-market prices from an empanelled panel of traders and users, strips out outliers, and publishes a single daily spot price.
