HOUSTON: Colombia's state-run Ecopetrol has launched a tender to buy a 195,000-200,000 barrel cargo of gasoline RON 92 to be received from September 30 to October 4 at Pozos Colorados, according to a document seen by Reuters on Tuesday.

The oil company has been increasing imports of finished fuels since its 80,000 barrel per day (bpd) Cartagena refinery in March started a major expansion program that will last until the second quarter of 2015.

For this offer, the company will receive bids until September 5 and they must refer to unleaded gasoline 87 prices from the US Gulf Coast.

The company last month bought on the open market up to 28 cargoes of ultra low-sulfur diesel (ULSD) to be received from September to March and two gasoline cargoes for this month.
