Fuel Regulations

Brazil: Diesel Fuel: Automotive Diesel Fuel

Overview

Specifications for transportation fuels are established by ANP (Agência Nacional do Petróleo, Gás Natural e Biocombustíveis) and published as ANP Resolutions.

Several grades of diesel are defined based on sulfur content. The most recent ANP 50/2013 specification [3129], Table 4, includes two sulfur content grades: S10 and S500. The resolution also defines where the different sulfur grades can be marketed.

Since 2009, the ANP resolutions define two types of diesel fuel:

  • Type A is diesel fuel that does not contain biodiesel, and
  • Type B is diesel fuel that contains biodiesel.

Vegetable oil is not permitted.

  1. Diesel fuel type permitted to be sold in large metropolitan areas of the country. A complete list can be found in Annex 1 of ANP Resolution 15/2006.
  2. Diesel fuel type permitted to be sold in the remaining cites.
  3. Not mandatory. If biodiesel is added, the content is to be reported. Biodiesel must meet specifications (ANP Resolution 42/2004 or its replacement) and contain a marker that allows verification of the biodiesel content.
  4. Alternatively, a minimum Cetane Index limit of 45 is allowed (NBR 14759 or ASTM D 4737). In case of dispute, ASTM D613 is the referee method.

  1. Starting January 1, 2014, S1800 shall not be sold for onroad use and will be fully replaced by S500.
  2. Applies to Type B diesel fuel only.
  3. Shall be within ± 0.5% volume of the percentage established by law. The determination of biodiesel content in Type B diesel fuel should be performed using EN 14078.
  4. Applies to Type A diesel fuel only.
  5. 820 to 853 kg/m³ for Type B diesel fuel.
  6. Alternatively, a minimum Cetane Index (NBR14759 or ASTM D4737) of 45 may be used for S500 and S1800 if the product contains no cetane improver. In case of dispute, ASTM D613 is the referee method.
  7. Applicable in production and imports.
  8. Alternatively, EN ISO 12937 may be used.
  9. Alternatively, EN 12662 may be used.
  10. Applicable to imports.
  11. Alternatively, EN 12916 may be used for Type B diesel fuel containing up to 5% biodiesel. ASTM D6591 and D5186 do not apply to Type B diesel fuel.
  12. Limit applies at the time and temperature of loading/pumping by the producer/distributor.
  13. Alternatively, ISO 12156 may be used with a limit of 460 µm max.
