Brazil's Chamber of Deputies advances fuel price breakdown bill

A bill (PL 4788/25) introduced by Deputy Guilherme Boulos in Brazil's Chamber of Deputies would require fuel stations and LPG retailers to detail the full composition of the price on the consumer receipt. The required breakdown includes the producer or importer cost, any bio‑fuel surcharge, federal taxes (CIDE, PIS/Pasep, Cofins), the state ICMS tax and the gross commercial margin.

The proposal expands the existing Law 12.741/12, which already mandates the display of tax components, aiming to give consumers clearer insight into price swings and to strengthen competition. The text is under analysis by the Consumer Defense, Constitution and Justice, and Citizenship committees and could be fast‑tracked to a plenary vote. It still needs approval by both the Chamber and the Senate to become law. Data cited from the Instituto de Estudos Estratégicos de Petróleo, Gás Natural e Biocombustíveis (Ineep) show the distribution margin in gasoline prices rose from 16.1% in April 2024 to 20% in July 2025, underscoring the demand for greater transparency.
