Platts proposes to launch B99 Chicago, Houston and New York assessments, update B100 effective May 4, 2026

Platts, part of S&P Global Energy, proposes to launch B99 price assessments for Chicago, Houston, and New York, and update its B100 assessment specifications, effective May 4, 2026.

New proposed assessments

Platts proposes to launch three daily B99 biodiesel price assessments, basis FOB Chicago, FOB Houston and FOB New York. Platts proposes to publish the B99 assessments as a premium to NYMEX NY ULSD Settlement Mo01 (NMHO001), and as outright prices, and would also provide monthly averages.

The proposed new assessments would be as follows:

The B99 assessments would reflect 99% biodiesel or Fatty Acid Methyl Ester (FAME) blended with 1% fossil diesel and would exclude the D4 biomass-based diesel Renewable Identification Number, the Clean Fuel Production Credit (45Z) and any other state credits.

Normalization would apply to different fuel volumes, higher or lower carbon intensity, delivery dates, as well as delivery by truck and rail.

The assessments would consider market information reported to Platts and published as heards throughout the day, including firm bids and offers, trades, and indicative values, as well as any other data deemed relevant to the assessment process.

The new assessments would be published at 1:30 pm CST and would follow a US publishing schedule.

Proposed modification to existing B100 assessments

Platts also proposes to modify the B100 Chicago and Houston assessment volumes and quality, and clarify the assessment incoterms.

Platts proposes to adjust the minimum volume to 125,000 gallons (2,976 barrels) and remove the maximum volume limit for both assessments. Volumes below the minimum requirement may be considered and normalized to this level.

Platts would also update the quality from Soy Methyl Ester to FAME to allow the inclusion of other feedstocks.

Platts would additionally like to clarify that the relevant assessments reflect FOB barge. Rail and truck volumes would be considered and may be normalized to reflect in-tank volumes.

The impacted assessments would include Biodiesel B100 Chicago (AAURR00), Biodiesel B100 Houston (AAURS00), as well as their respective monthly averages. These assessments reflect 100% biodiesel and factor in both the D4 RIN and the Clean Fuel Production Credit (45Z).

These adjustments would more accurately represent the US biodiesel spot market, as indicated by market feedback.

The summary of proposed changes would be as follows:

In the absence of market indications Platts may assess the B100 prices using the B99 price assessment plus the D4 RIN and the Clean Fuel Production Credit (45Z).

B100 assessments are available on fixed pages PBF010, PBF011, PBF310 and PBF311, as well as in the Platts Biofuelscan and Biomass-Based Diesel Report. The new assessments would also be published within these same fixed pages and publications.
