In Paranagua, private warehouses reached their maximum storage capacity of 3.5 million tons, Luiz Teixeira da Silva, Paranagua’s operations director told Bloomberg. A terminal operated by VLI Logistics, one of the two at Santos port that store fertilizers, is also full, according to people with knowledge of the matter who asked not to be named as the information isn’t public.
