Platts to launch B30 Singapore biobunker assessments, update B24 LSFO volume

Platts, part of S&P Global Commodity Insights, will launch B30 Singapore biobunkers assessments and update the volume specification for the existing B24 low sulfur fuel oil (LSFO) assessments, to better reflect current market dynamics, effective Oct. 1, 2025.

B30 Biobunkers Singapore

Increased volumes of B30 biobunker grades were observed to be traded in Singapore, following the Maritime and Port Authority of Singapore raising the allowable biofuel blend carriage limit from 25% to 30% on conventional bunker tankers operating in Singapore from March 7, 2025.

The new assessments will reflect the marine fuel blend of 30% biodiesel with low sulfur and high sulfur fuel oil respectively delivered in Singapore. Platts will publish the market-based assessments as differentials to the respective Platts fuel oil FOB Singapore cargo assessment (AMFSA00), and as outright values. The other specifications will match those of the existing equivalent B24 biobunkers assessments.

The assessment specifications will be as follows:

Other delivery periods and volumes may be considered in the Platts Market on Close assessment process and normalized back to the above specifications.

The assessment will reflect specification standards in line with the ISO 8217:2017. Platts recognizes the latest ISO 8217:2024 specifications for marine fuels and will consider indications using this standard within the assessment.

The biobunker stems considered for the new Singapore biobunker assessments will reflect bio-components that hold proof of sustainability obtained in the framework of voluntary schemes approved by the European Commission, such as ISCC.

In addition, the biobunker stems will specify a minimum of 84% GHG savings for the biofuel component, which is equivalent to the default emissions value of 14.9 gCO2eq/MJ against the 94 gCO2eq/MJ comparator, under the EU Renewable Energy Directive.

Platts will not consider biobunkers that use palm oil methyl ester as a biocomponent.

The new daily biobunkers assessments will be timestamped to 5:30 pm Singapore time market close and will follow the Platts Singapore publishing schedule.

Platts spot price assessments consider market information reported to Platts and publishes the information throughout the day, including firm bids and offers, transactions and indications of value. In the absence of observable spot market activity, Platts may consider other verifiable data reported.

The assessment will be published on Platts Biofuels Alert, in the Bunkerwire Report, Biofuelscan Report and Biomass-Based Diesel Report.

B24 Biobunkers LSFO Singapore

In addition, Platts will update the volume of its current B24 biobunkers LSFO Singapore assessments (LSFOB00 and LSFOO00) to 500-1,500 mt, from 500-1,000 mt, effective Oct. 1, considering feedback from market participants and observable trade data from Platts on the increasing stem volumes of B24 LSFO transactions. Other specifications of the existing B24 LSFO assessments will remain unchanged.

This decision follows a proposal that was published here Aug. 14, 2025.
