TOKYO, March 1 (Reuters) - Two aluminium buyers in Japan have agreed to pay producers a premium of $115 per tonne for lower-grade product for shipment during the three months to June, two sources directly involved in the matter said.
The two companies struck the deals after a U.S. producer asked for a premium of $115, sharply below Rio Tinto Alcan's offer of $132, sources said.
"Talks have just started but they have hit snags over premiums on higher-end products," said a source directly involved in the talks.
"It wiill take a while for the whole negotiation process to be complete," the source said.
