The Decree 7412/2006 regulates the 2748/2005 law (biofuel law). It obliges:
- Biodiesel to meet the requirements established by the Norm PNA 16 018 05 (or the latest edition of the norm).
- Ethanol related blends to meet the requirements established by the norm 025 approved by Decree 20.842/80.
In 2009, Decree 4952 amended Decree 7412 in order to allow E85 biofuel.
In 2013, Decree 10703 of 2013 consolidated these two decrees.
In 2015, Decree 2998 modified the decree 10703 to exempt aviation fuel and fuel above 97 octanes to have absolute ethanol in the mix.
The distribution companies must inform the ministry of industry and commerce between the 1st and 10th of each month the purchases of biofuels of the previous month.
