Updates with further details
SINGAPORE, Nov 10 (Reuters) - Taiwan's Formosa Petrochemical Corp (FPCC) has started offering term cargoes of 10ppm-sulphur and 500ppm-sulphur gasoil for loading next year, three sources familiar with the matter said on Monday.
The privately-owned refiner is seeking to sell at least one 750,000-barrel cargo of 10ppm-sulphur gasoil and one 300,000-barrel cargo of 500ppm-sulphur gasoil per month, one of the sources said.
The tender closes on Tuesday, two of the sources said, with one source adding that the validity is until the end of the month.
FPCC did not immediately respond to a Reuters request for comment.
For this year, FPCC's term cargoes for 10ppm were sold off at slight premiums of up to 30-40 cents per barrel linked to free on board Singapore quotes to several Western and regional trading houses, traders say.
