Platts to include Hydradd C9000 cetane improver in Singapore gasoil from Oct. 8

Platts, part of S&P Global Energy, would like to clarify that with effect from Oct. 8, 2026, following a review of recognized additives contained in the FOB Singapore gasoil assessment process, it will begin to reflect Hydradd C9000 cetane improver by Scandinavian Oil Services.

Platts understands that Hydradd C9000 cetane improver is a relabel of Cetpro Micet's 2-Ethyl Hexyl Nitrate, an additive which has been reflected in the FOB Singapore gasoil assessment process since Jan. 22, 2015.

For the full list of previously identified additives, please review the Asia Pacific and Middle East Refined Oil Products Specifications Guide.

The list of Platts gasoil recognized additives is intended to provide clarity to market participants regarding which additives are generally considered merchantable and accepted for cargoes delivered through the Platts Market on Close assessment process in Singapore. Platts does not align its FOB Singapore additives acceptance to any particular importing country.
