State-owned Saudi Aramco has, in a rare move, placed a vessel on subjects to ship a July-loading cargo of naphtha to Japan from Saudi Arabia, market sources said.

Aramco typically sells naphtha on a FOB basis.

According to shipping sources, Aramco has the New Challenge on subjects to ship 55,000 mt of naphtha from Ras Tanura to Japan, loading July 30, at w127.5. Subjects are due to lift Monday.

The Middle Eastern giant supplies A180 and A310 naphtha from Ras Tanura.
