Shortlanding Claims in Dry Bulk Commodity Trade

A shortlanding claim arises when the quantity of bulk commodity received at the discharge port is less than the quantity stated on the bill of lading or certified by the loading port draft survey. In international dry bulk trade, shortlandings are a routine occurrence: some difference between loading port and discharge port weight measurements is expected because of measurement tolerances, moisture evaporation during transit, and minor sampling losses during the voyage. The commercial question is whether the difference exceeds the contractual tolerance—in which case it is actionable—and whether the shortfall represents genuine cargo loss or a measurement discrepancy.
Establishing the Discharge Port Quantity
Discharge port quantity determination is most commonly done by one of three methods: discharge port draft survey, certified shore scales, or cargo scanning. The method depends on the commodity type, the port's available facilities, and what the contract specifies as the governing quantity method.
Discharge port draft survey measures the vessel's displacement before and after discharge, applies the same mechanics as the loading port survey—ballast deductions, fresh water allowance, trim correction—and produces a quantity figure that can be compared to the loading port figure. As discussed elsewhere, draft survey accuracy is approximately 0.3 to 0.5 percent, meaning that even with no actual cargo loss, the two surveys may produce results differing by 150 to 250 tonnes on a 50,000-tonne cargo. When the loading port and discharge port surveys are conducted by different surveyors using different instruments and in different water conditions, the combined measurement uncertainty is larger.
Certified shore scales—conveyor belt scales or truck scales at the discharge facility—provide more accurate quantity measurement when the equipment is properly calibrated. For grain discharged into storage facilities with belt scales, the scale total is often treated as the more reliable figure. The key requirement is that the scale is calibrated and certified to a recognized standard, and that a witness for the buyer was present during the weighing process.
Analyzing Whether the Shortfall Is Actionable
Once the discharge quantity is established, the shortfall is calculated by comparing it to the loading quantity as certified. The next step is to determine whether the difference falls within or outside the contractual tolerance. Most GAFTA and standard bulk commodity contracts allow a tolerance—typically 0.5 percent—within which weight differences are not actionable. A loading port figure of 50,000 tonnes and a discharge port figure of 49,800 tonnes represents a 200-tonne difference, which at 0.4 percent of cargo weight falls within the standard GAFTA tolerance. The same cargo arriving at 49,500 tonnes—a 500-tonne shortfall at 1 percent—exceeds the tolerance and is potentially actionable.
The contractual question is which party's weight figure governs. Under a loading-final contract, the loading port draft survey is the invoiced quantity—the buyer agreed to pay for the loading weight, and the discharge weight is not commercially relevant to payment. Under a discharge-final or outurn weight contract, the discharge measurement governs. A buyer who accepted loading-final terms and subsequently discovers a shortfall has limited commercial recourse for the quantity difference unless they can demonstrate that the loading port figure itself was incorrect.
Cargo loss during transit—from moisture evaporation, seawater entry, or theft—is distinct from survey measurement difference. If independent evidence suggests that cargo was removed from the holds during transit (damaged hatch covers, unexplained access by the vessel's crew, or third-party witnesses to cargo removal), the claim shifts from a weight dispute to a potential cargo theft or negligent carriage claim against the vessel owner. This requires different evidence and different claim mechanics than a standard quantity shortfall.
