Platts to update the sustainable aviation fuel CIF ARA density specification

Platts, part of S&P Global Commodity Insights, will update the density reflected in its daily SAF assessments to better align it with industry standards for the HEFA production pathway, effective Oct. 20, 2023.

The density will be updated to 760 kg/cu m at 15 degrees Celsius, compared with the current assessment density of 776 kg/cu m at 15 C.

The change comes in line with the ASTM D7566 standard for Synthesized Paraffinic Kerosene from Hydroprocessed Esters and Fatty Acids, which provides a density range of 730-772 kg/cu m at 15 C, as well as market feedback that the reference density of HEFA SAF should be 760 kg/cu m.

In the Platts Market on Close assessment process, Platts may publish bids, offers and trades for SAF with other specific gravity or density values, but these may be normalized for assessment purposes.

The change affects the following assessments:

SAF CIF ARA AJNWD00 and SAF CIF ARA Premium AJNWF00.

Platts will also update the conversion rates to reflect the change in reference density. Platts will publish the SAF prices in $/mt, using a 347.594 conversion factor to $/gallon, which implies a $/mt to $/barrel conversion factor of 8.276.

These assessments appear in Biofuelscan, Weekly Biomass Based Diesel report and the Platts price database under the codes above.
