The Margin Killers: Where Food Export Deals Quietly Lose Money

Last reviewed: August 2026

Nobody loses money on the price. They lose it on everything that happens after the price is agreed. A quote goes out at a margin you're happy with, and by the time the container clears, that margin has been eaten by charges nobody discussed, a weight discrepancy nobody expected, and a claim nobody planned for. This guide is a tour of where the money actually goes — and how to price and word your quotes so it stops going there.

1. Demurrage and detention — the two clocks most exporters confuse

These are different charges, they run on different clocks, and mixing them up is expensive. Demurrage accrues when your container sits inside the terminal past its free time. Detention accrues when the container is outside the terminal — at the buyer's warehouse, or yours — past its free time. Both are billed per container per day, and both escalate in tiers: the daily rate typically rises the longer it runs.

They are dangerous precisely because they're nobody's fault in particular. A customs inspection, a missing document, a buyer whose warehouse is full, a port congestion event — none of it is negligence, and all of it burns days. On a delayed clearance across a few containers, this line item alone can exceed the entire margin on the shipment.

What to do: know the free-time allowance on your booking before you quote, not after. State in your quote which party bears demurrage and detention at each end, and from when. If you're quoting a delivered term (DAP, DDP, CIP to an inland point), you are carrying that risk further than you may realise — a buyer who is slow to collect is spending your money.

2. The weight discrepancy nobody budgeted for

You ship what your scale says. The receiving weighbridge says something else. On bulk and semi-bulk food commodities — pulses, grains, nuts, dried fruit — a small percentage difference on a full container is real money, and the argument that follows is worse than the loss.

Moisture is usually the culprit. Product that leaves at one moisture content arrives at another, and the direction depends on the voyage, the packaging and the destination climate. There are also legitimate differences between scales, calibration dates, and whether the weight is net, gross, or gross-including-tare.

What to do: state on the invoice and packing list exactly which weight basis you're selling on. Where moisture is material, specify the moisture percentage in the contract and agree a tolerance in writing — a stated tolerance turns a dispute into arithmetic. For higher-value loads, an independent weight and sampling certificate at loading costs a fraction of the argument it prevents.

3. Quality claims — where the real money disappears

This is the biggest single margin killer in food trade, and the one exporters least like to plan for. Goods arrive, the buyer says they're off-spec, and now you're negotiating a discount from a position of total weakness: your product is in their country, in their warehouse, possibly perishing, and shipping it back costs more than the claim.

The pattern to recognise is that a claim's merit and a claim's cost are barely related. A buyer with a weak claim and possession of your goods is still in a strong commercial position. Some buyers know this.

What to do: three things, all cheap, all before shipment. First, agree the specification in writing with numbers and tolerances, not adjectives. Second, agree how quality will be determined at destination — whose lab, whose method, within how many days of arrival — because an undefined claim process favours whoever is holding the goods. Third, consider independent inspection at loading (SGS, Bureau Veritas, Intertek) for any load where a claim would hurt. It is not an admission of doubt; it is the cheapest insurance in the trade, and sophisticated buyers respect it.

4. Charges that live outside the freight rate

The freight number your forwarder quotes is rarely the freight number you pay. Around it sit terminal handling charges at both ends, documentation fees, seal fees, bunker and low-sulphur adjustments, peak season surcharges, general rate increases, congestion surcharges, and — for reefer cargo — plug-in and monitoring charges at the terminal.

The trap is not that these exist. It is that they change between the day you quote and the day you book, and that under a CFR, CIF, CPT or CIP term, most of them are yours.

What to do: ask your forwarder for an all-in rate, and ask specifically what is excluded. Put a validity period on your quote that does not outlive your freight quotation. Add one line stating that carrier surcharges are subject to change — it costs you nothing and gives you a legitimate basis for a conversation if rates move.

5. Currency drift on the quiet

You quote in USD or EUR. Your costs are in your own currency. Between quotation and payment — which on a documentary collection or a slow open-account arrangement can be months — the rate moves. On a thin-margin commodity trade, an adverse move of a few percent can exceed the entire profit on the deal.

What to do: know your break-even exchange rate before you quote, not after. Keep quote validity short enough that you can requote if the currency runs against you. For larger or longer-dated deals, talk to your bank about a forward contract — it removes the upside too, but a locked margin you can bank beats a speculative one you cannot.

6. Payment terms as a hidden cost

Extending 60 or 90 days to a buyer is not a courtesy — it is a loan, and it has a price. That money is not in your account financing your next purchase, and if you're drawing on a facility to bridge it, you're paying interest on your own sale. Letters of credit carry their own costs: issuance, advising, confirmation where you need it, amendment fees, and discrepancy fees when documents don't match — which, on first presentation, they frequently don't.

What to do: price the terms into the number. A 90-day open-account price and a cash-against-documents price should not be the same price, and stating that plainly ("net 90 available at +X%") often produces a buyer who suddenly prefers shorter terms. Where an L/C is involved, read the document requirements before you accept it, not at presentation.

7. The costs of a deal that dies late

The worst outcome is not a low margin. It is a deal that collapses after you've committed. Product bought or reserved against an order that evaporates, a booking cancelled after the cutoff, samples couriered, lab work done, certificates obtained for a market you're no longer shipping to — these are real cash costs, and they attach disproportionately to inquiries that were never serious in the first place.

What to do: qualify harder at the front. The cost of a lost afternoon is trivial; the cost of committing product and freight to a phantom order is not.

The quote-side fixes, in one place

Almost every leak above is closed by something written into the quote. If you change nothing else, change these:

1. A validity period that does not outlive your freight quotation or your currency assumption.
2. The Incoterm with its named place — and awareness of how far down the chain that carries your risk.
3. A stated weight basis, and a moisture tolerance where moisture is material.
4. A defined specification with numbers, and a defined claim process at destination.
5. Explicit allocation of demurrage and detention at both ends.
6. A note that carrier surcharges are subject to change.
7. Payment terms priced, not given away.

None of that makes your quote longer than a page. All of it makes the difference between a margin you projected and a margin you keep.

Price what you actually agreed to

Most of these leaks start the same way — something the buyer specified, or failed to specify, that didn't make it into the quote. AgrifoodQuote reads an inbound inquiry and pulls out the Incoterm, the destination port, the quantities, the certifications and the timeline, then flags what's missing before you reply. You set every price and every term; the tool makes sure you're pricing the deal that was actually asked for.
