Pakistan State Oil (PSO) is set to buy a January jet fuel cargo at slightly higher premiums than what it paid for previous cargoes, industry sources said on Friday.

The refiner was seeking 25,000 tonnes of jet A-1 fuel for delivery in January through a spot tender that closed on December 5 and is valid until December 10.

Oman Trading International had the lowest bid of $4.16 a barrel above Middle East quotes on a delivered basis, while Sahara Energy had the highest bid premium of $5.47 a barrel, one of the sources said.

BB Energy, Galana Oil, Mercuria and Total were the other companies which took part in the tender, the source said.

PSO last bought two 50,000 tonne cargoes of jet fuel for November-December delivery from Vitol at a premium of $4.04 a barrel CIF to Middle East quotes.

It also bought an optional cargo for delivery over the same period from Vitol at a premium of $5.25 a barrel CIF to Middle East quotes.
