Overview

• Federal agents retained 91 million liters of imported diesel and about 115 tonnes of fuel additives worth more than R$290 million in two ships and containers bound for Rio de Janeiro and São Paulo.
• ANP ordered a precautionary, indefinite interdiction of Refit’s Manguinhos facility after inspections indicated the plant was not refining crude but mixing imported semi‑finished fuels, suspending operations.
• Authorities are examining suspected misclassification of inputs such as nafta or condensate, simulated sales through layered invoices, concealment of beneficiaries, and irregular disclosures to regulators, with samples sent for forensic testing.
• The action is part of Operação Cadeia de Carbono, an expansion of earlier probes into laundering and tax fraud linked to fuel chains investigated in Carbono Oculto, with officials signaling more operations in the coming weeks.
• Refit denies wrongdoing and says it will seek to reverse the measure, while ANP states Petrobras’ Reduc can supply the market and that there is no risk of fuel shortages.
