The Inspection Passed at 35°C. The Cargo Arrived at -5°C.
Quote from Guest on May 14, 2026, 10:13 amCommodities inspected in tropical conditions may behave differently in cold climates. How temperature changes during transit alter physical properties.
A palm oil trader shipped 8,000 MT of RBD palm olein from Port Klang, Malaysia, to Gdansk, Poland. Loading in August at 34°C ambient. The product was liquid, clear, and within specification — cloud point 10°C, iodine value 58, FFA 0.08%.
The vessel transited the Indian Ocean, Suez Canal, and Mediterranean. By the North Sea in September, ambient temperature dropped to 8°C. Cargo temperature in the tanks: approximately 12°C. At Gdansk, discharge temperature: 7°C. The palm olein began to crystallize — the cloud point was 10°C. At 7°C, the product was partially solidified. Discharge pumps could not handle the viscous material at normal rate. Discharge took 4 days instead of 2. The buyer's refinery needed reheating: additional cost of approximately $12,000.
The buyer filed a quality claim. The seller argued the product met all specifications at loading and that crystallization was caused by destination temperature, not product quality.
The Specification Describes the Product at Reference Temperature, Not at Every Temperature
Palm olein's cloud point — typically 8 to 12°C — defines the temperature below which the oil solidifies. At tropical load ports, this is not an issue. At northern European discharge ports in autumn, ambient temperature can be at or below the cloud point. Oil that was liquid in Malaysia becomes semi-solid in Poland.
This is not a quality defect. It is a physical property. The specification tells the buyer exactly what temperature the product will begin to solidify. A buyer purchasing for Gdansk in September should know that ambient temperature may be below the cloud point.
Contracts for temperature-sensitive commodities shipped to cold destinations typically include a heating clause — the seller must ensure the cargo is heated to a minimum discharge temperature, usually 5 to 10°C above cloud point. This requires the vessel's heating coils to be operational. Heating cost: typically $2 to $5 per MT.
This contract had no heating clause. The charter party specified the vessel had heating coils, but did not require heating to a minimum discharge temperature. No instruction was given to the master.
The Product Was On-Spec. The Delivery Was Not Fit for Purpose.
The distinction between meeting a specification and being fit for purpose at the destination is where temperature-sensitive disputes arise. The specification confirms characteristics at reference temperature. Fitness at the destination depends on whether those characteristics are maintained at ambient conditions.
Settlement: approximately $18,000 — additional port charges ($8,000) plus reheating ($12,000) minus buyer contribution for not specifying heating. Modest relative to the $6.4 million cargo value, but the dispute consumed 6 weeks.
Traders shipping temperature-sensitive commodities to cold destinations include heating clauses as standard. The clause specifies minimum cargo temperature at discharge, the responsible party for heating instructions, and cost allocation. The cost of the clause: zero. The cost of omitting it: the dispute that arises when liquid product arrives as paste — on-spec, but not in any condition the buyer can use.
