A cargo of grain, metal or crude is loaded late. By the time it reaches the buyer, the market has fallen well below the contract price. The buyer refuses to pay in full; the seller insists the price was fixed the day the contract was signed. Both sides are technically right, which is exactly why these disputes end up in arbitration rather than at a negotiating table.
Delay Is Rarely the Real Dispute
Late shipment looks like the grievance, but it is usually only the trigger. The real fight is over which party absorbs the gap between the contract price and the price on the day the goods, or their notional substitute, actually change hands. A commodity dispute arbitrator starts by asking a narrower question than “who caused the delay”: was the delay a breach of a condition entitling the innocent party to treat the contract as at an end, or a lesser breach sounding only in damages for the delay itself? The answer determines whether the price fall is recoverable, because a party that affirms a late contract cannot then claim the market moved against it before performance was eventually rendered.
How the Standard Trade Forms Actually Price the Loss
Most physical commodity contracts are traded on GAFTA or FOSFA standard forms, and both carry a default clause that fixes how damages are measured once a breach is established: the difference between the contract price and the market or resale price on the date of default. The UK Supreme Court confirmed the modern approach to that calculation in
Sharp Corp Ltd v Viterra BV [2024] UKSC 14, holding that where an available market exists on the date of default, that market price ordinarily sets the default price, valued on a notional substitute contract on the same terms rather than the price of the actual goods sitting wherever they happen to be. A decade earlier,
Bunge SA v Nidera BV [2015] UKSC 43 held that the default clause is not a complete code: the ordinary compensatory principle of English law applies underneath it, so a party cannot recover more than its actual loss even where the clause, read literally, might suggest otherwise. Together the cases show a tribunal will not apply the formula mechanically; it tests it against what the innocent party truly lost.
GAFTA and FOSFA first-tier references are usually heard by a sole arbitrator, but an appeal, as in Sharp v Viterra, goes to a Board of Appeal sitting as a panel, and a party’s nominee there sits as a member of an arbitral tribunal rather than alone, which changes how the case should be argued and how much deference the eventual award is likely to receive from a reviewing court.
Risk, Delivery Terms and the Freight Leg
Where risk passes matters as much as when it passes. Under an FOB contract, risk in the goods generally transfers to the buyer once they cross the ship’s rail or are loaded, so a fall in price during the ocean leg is, in principle, the buyer’s problem, not the sellers. Under CIF terms, the seller’s documentary obligations, tendering conforming shipping documents on time, matter more than the physical condition of the cargo, which is why CIF disputes often turn on paperwork rather than the commodity itself. Delay caused by the carriage itself, rather than by the seller’s failure to ship on time, brings a different set of questions: demurrage, laytime and notice of readiness are creatures of the charterparty, not the sale contract, and a shipping dispute arbitrator will usually be brought in separately to apportion that piece of the loss under London Maritime Arbitrators Association practice, even while the sale-contract price dispute runs in parallel under GAFTA or FOSFA rules.
When the Paper Trail Becomes the Dispute
Physical commodity trades are rarely paid on trust; a letter of credit usually sits behind the contract, and banks examine documents strictly rather than the underlying facts of delay or market movement. A discrepant bill of lading or a late presentation can let an issuing bank refuse to pay regardless of who was commercially at fault, which is why a banking and bank documents dispute arbitrator is so often needed alongside the underlying price claim. Getting the documents right, or proving they were rejected wrongfully under UCP 600, can matter more to final recovery than the price dispute itself.
Cross-border trades add a further layer: export licensing, sanctions screening or a customs valuation dispute can independently delay a shipment before the market even moves, and an export import dispute arbitrator is often the one untangling whether a regulatory hold-up excuses the seller under force majeure or was foreseeable and should have been priced into the contract.
The Sector Rarely Changes the Principle
Whether the cargo is base metal, grain or crude, the legal test is the same, even though market mechanics differ. Metal priced against LME reference rates, oil priced off Brent or WTI, and agricultural commodities priced on GAFTA terms all share one starting point: a contract that fixes a price, a market that moves and a tribunal deciding whether the movement is the seller’s risk, the buyer’s risk or was never caused by the delay at all. These disputes increasingly draw on arbitrators equally comfortable applying English sale-of-goods principles and reading a documentary credit; an English Arbitrator in USA background applying London market practice to a dispute between American counterparties is a familiar profile.
The Bottom Line
A falling market does not, by itself, create a claim. It only crystallizes one that already existed in the contract’s allocation of risk, its delivery terms, and whatever breach, if any, actually occurred. Establishing the date of default precisely, and the market price on that date, usually does more to decide the outcome than arguing about why the ship was late in the first place.
