Kuwait Petroleum Corp (KPC) has issued a tender to sell spot naphtha cargoes for July loading from its ports, marking its first such offer since the onset of the US-Iran conflict, according to trade sources and a document reviewed by Reuters.

The state-owned oil firm is offering either 55,000 metric tons (495,000 barrels) or 80,000 tons of the petrochemical feedstock, with loading scheduled for July 5-6 at any Kuwaiti port, the document showed.

The tender closes on June 22 with same-day validity.

The refiner’s last such naphtha tender was for February shipments in January, two of the sources said.
