The Retention Sample Was Lost. The Dispute Became Unresolvable.
Quote from chief_editor on May 4, 2026, 4:14 amWhen retention samples are lost or improperly stored, commodity quality disputes become impossible to resolve. How sample management determines dispute outcomes.
An iron ore trader shipped 60,000 MT of pellet feed from Brazil to China. The load port survey showed Fe content at 65.2% — within the contract minimum of 65.0%. The discharge survey showed Fe at 63.8% — below the minimum and below the rejection threshold of 64.0%. The buyer rejected the cargo.
The contract included a standard referee clause: if load port and discharge port results differed by more than a specified tolerance, the retained referee samples from both surveys would be sent to a mutually agreed third-party laboratory for final determination. The referee result would be binding on both parties.
The trader invoked the referee clause. The load port surveyor was contacted to provide the retained sample. The surveyor reported that the retention sample had been stored at their laboratory in Vitória, but due to a storage reorganization, the sample had been discarded after 60 days — 5 days before the referee request was received. The contract specified sample retention for 90 days. The surveyor's standard operating procedure specified 60 days. The surveyor had followed their own procedure, which conflicted with the contract requirement.
Without the load port retention sample, the referee analysis could only be conducted on the discharge port sample — which confirmed the discharge result of 63.8%. The trader lost the referee mechanism. The buyer's discharge result stood as the only complete evidence. The trader's claim that the cargo was on-spec at loading could not be supported by a referee analysis because the evidence had been destroyed.
The financial impact: a rejection on 60,000 MT of pellet feed worth approximately $7.2 million. The cargo was eventually accepted at a price reduction of $4 per MT — approximately $240,000. Without the referee mechanism, the trader had no commercial advantage to contest the discharge result.
The Referee Sample Is the Evidence. Without It, You Have No Case.
Quality disputes in commodity trade are resolved by evidence. The evidence is the sample. Not the certificate — the certificate is a report of the analysis of the sample. If the sample is lost, contaminated, improperly stored, or destroyed, the certificate cannot be independently verified. The party without a sample is the party without evidence, and the party without evidence loses the dispute.
Retention samples serve three functions: they allow re-analysis if the original result is questioned, they enable referee determination when load port and discharge port results conflict, and they provide evidence in arbitration proceedings. Without retention samples, the dispute collapses to a he-said-she-said argument between two certificates — and arbitration tribunals consistently give more weight to the party that can produce the sample over the party that can only produce the certificate.
The storage and preservation requirements for retention samples vary by commodity: iron ore samples should be stored in sealed, moisture-proof containers at ambient temperature; grain samples require temperature-controlled storage to prevent degradation; metal concentrate samples must be stored to prevent oxidation, which can change the analytical results. The retention period must match the contract's dispute resolution timeline — if the contract allows 90 days for quality claims and the referee process takes 30 additional days, the retention period should be at least 120 days.
The operational instruction for traders is to specify the retention period in the inspection contract — not rely on the surveyor's standard procedure — and to confirm, when the inspection is complete, that the surveyor has acknowledged and committed to the contractual retention period. This confirmation should be in writing. The cost of this confirmation is one email. The cost of a lost retention sample, in this case, was $240,000.
The Surveyor's Liability Does Not Cover the Trader's Loss
The trader explored a claim against the load port surveyor for destroying the retention sample before the contractual retention period expired. The surveyor's terms of business limited liability to 10 times the inspection fee — approximately $180,000. The trader's loss was $240,000. Even if the trader recovered the maximum from the surveyor, the recovery would not cover the full loss. And the recovery required demonstrating that the surveyor's failure to retain the sample for 90 days directly caused the trader's loss — a causation argument that the surveyor contested, arguing that even if the sample had been retained, the referee result might not have supported the trader's position.
The claim was settled for approximately $95,000 — the surveyor acknowledged the retention failure but disputed the quantum of damages. The trader's net unrecovered loss was approximately $145,000.
The iron ore was the same cargo at load and discharge. The Fe content did not change — or if it did, the change was likely minimal for iron ore pellet feed during a 30-day voyage. The discrepancy between 65.2% and 63.8% was most likely attributable to sampling methodology differences between the two ports. The referee mechanism was designed to resolve exactly this type of discrepancy. The mechanism required a sample. The sample was gone. The mechanism failed. The $240,000 price reduction was not the cost of bad cargo. It was the cost of a missing sample — 200 grams of iron ore dust in a sealed container that should have been on a shelf in Vitória for another 35 days.
