NAPHTHA SPOT DEALS: South Korea's LG Chem bought two cargoes totalling an average of 50,000 tonnes of naphtha for first-half July delivery at premiums of about $2.00 a tonne to Japan quotes on a cost-and-freight (C&F) basis, traders said.

- They added that the cargoes could be delivered to Daesan.

- LG Chem operates two crackers in South Korea, one in Daesan and another in Yeosu.

- It had previously paid about $1.75 a tonne premium for a cargo scheduled for first-half July arrival at Yeosu.

- Cargoes delivered to Yeosu usually fetch a slightly lower price versus those shipped to Daesan.

- Since May 17, China, South Korea and Taiwan have bought at least 480,000 tonnes of naphtha through tenders from the spot market for first-half July delivery.

- But its naphtha inventories were down 290,000 barrels to 9.8 million barrels.

- Gasoline stocks in the United States were forecast to have fallen by 1 million barrels last week, a preliminary Reuters poll showed on Tuesday.
