HOUSTON, June 3 (Reuters) - Colombia's state-run company Ecopetrol ECO.CN has launched a tender to buy a 195,000-200,000 barrel cargo of gasoline RON 92 for delivery in June, according to an invitation seen by Reuters on Tuesday.

The oil firm bought several cargoes of gasoline, diluent naphtha and ultra low-sulfur diesel (ULSD) on the open market in May, while its 80,000 barrel per day (bpd) Cartagena refinery is ongoing a major expansion that started in March.

This cargo must be delivered on June 16-18 at the U.S. Gulf Coast or any port in the Caribbean, and it can also be unloaded on June 24-26 at Pozos Colorados, Colombia.

Ecopetrol will receive bids until June 3 and they must be indexed to unleaded gasoline 87 prices from the U.S. Gulf Coast.
