Transit Loss Allowances Cover Less Than Traders Assume
Quote from chief_editor on June 29, 2026, 5:30 pmTransit loss allowances in commodity contracts cover natural loss within defined limits. They do not cover theft, contamination, or handling damage masquerading as transit loss.
The GAFTA 100 contract provided a 0.5% transit loss allowance — a standard provision reflecting natural moisture loss, dust, and handling attrition during bulk grain voyages. When a Panamax cargo of wheat arrived at Karachi with a measured weight shortfall of 0.8% versus the bill of lading quantity, the receiver's first calculation was: 0.8% minus 0.5% allowance equals 0.3% claimable loss. They filed a claim for the excess.
The shipper's response noted several things the receiver had not addressed. The transit loss allowance in the contract was designed to cover natural moisture evaporation and handling losses that occur during normal voyages. The cargo had been loaded in a humid Black Sea port in August, when grain moisture content is often near the upper specification limit. The voyage had been 22 days — on the longer side for a Black Sea to Pakistan voyage due to Suez Canal congestion. The receiver's discharge survey methodology had used draft survey, which the shipper argued had an inherent measurement error that accounted for part of the apparent shortfall.
The dispute went to GAFTA arbitration. The key question was not whether the transit loss allowance applied, but what portion of the measured shortfall fell within the scope of the allowance versus outside it.
What Transit Loss Allowances Are Designed to Cover
Transit loss allowances in commodity contracts exist because natural physical processes cause bulk commodities to lose measurable weight during ocean voyages. Grain loses moisture as it dries in the hold. Bulk sugar loses surface crystals to dust and fine material. Metal concentrates lose moisture that was present at loading. These losses are inherent to the commodity and the transit process and are not attributable to anyone's fault — they are simply the physics of moving hygroscopic or friable bulk materials across temperature and humidity gradients.
The allowance provides a no-fault tolerance zone: the buyer agrees not to claim for shortfalls within the allowance, and the seller agrees not to dispute shortfalls below the allowance threshold. The commercial purpose is to avoid disputes over small measurement differences that are within the range of natural variation and measurement error combined.
The allowance is not designed to cover: theft of cargo during loading, transit, or discharge; contamination that reduces the effective commercial quantity; handling damage that results in material loss through spillage; measurement fraud; or cargo that was simply not loaded despite being documented as such. These are separate events with separate liability regimes, and they do not fall within the transit loss allowance framework regardless of how they manifest in a weight measurement comparison.
The distinction matters because a party who suffers a loss from theft or handling damage but measures it as a weight shortfall may attempt to claim under the transit loss allowance framework. The allowance may apply to part of the apparent shortfall — the natural loss portion — while the balance requires a different claim theory.
Establishing What the Shortfall Actually Represents
When the measured shortfall exceeds the transit loss allowance, the claiming party faces the investigative challenge of establishing what caused the excess. Several categories of evidence bear on this.
Moisture analysis at loading and discharge: if moisture content was measured by the pre-shipment inspection at loading, and again by the discharge survey at destination, the moisture difference represents water lost during transit. Converting that moisture loss to weight loss using the cargo quantity and density provides an estimate of natural moisture loss. If natural moisture loss accounts for most of the measured shortfall, the excess over the allowance may still be within measurement tolerance.
Vessel hold condition: the pre-loading hold inspection report documents the condition of the vessel's holds before loading. A hold with residual moisture from a prior cargo, inadequate ventilation, or hatch seal deficiencies would produce higher natural loss and potentially moisture-related cargo damage. If the vessel's hold condition contributed to the loss, the shipowner may bear liability.
Survey methodology comparison: draft survey accuracy at load port and discharge port may differ based on sea conditions, surveyor competence, and vessel calibration records. Comparing the two surveys' estimated accuracy ranges may explain part of the apparent shortfall without any actual cargo loss.
The Karachi wheat case produced a GAFTA award that allocated the total measured shortfall between natural transit loss within allowance, measurement tolerance at both ends, and a residual unexplained shortfall that the shipper was required to compensate. The residual was approximately 0.1% of cargo weight — significantly less than the 0.3% the receiver had initially claimed. The allowance, combined with measurement tolerance analysis, absorbed most of the apparent loss.
Transit loss allowances reduce dispute frequency by setting a tolerance zone. They do not resolve disputes when measured shortfalls are larger than the allowance and the cause of the excess is ambiguous.
