The MV Recife sailed from Durban to ports in the Americas in July 1991. Control Chemicals (Pty) Ltd, the appellant, shipped a container of calcium hypochlorite tablets (a dangerous oxidising substance) under a bill of lading governed by the Hague-Visby Rules. Approximately 50 days into the voyage, while off Florida, an explosion and fire occurred in the container stowed on the top tier of the deck, damaging the vessel and nearby cargo. The carrier (Safbank Line Ltd) and associated parties sued the shipper for damages, alleging that the explosion was caused by defective or contaminated calcium hypochlorite or improper stowage within the container. Negligence was conceded not to be proven, and the claim proceeded purely in contract under article IV rule 6 of the Hague-Visby Rules.
