TOKYO, June 27 (Reuters) - Some Japanese aluminium buyers have agreed to pay producers a premium of $90 per tonne for metal to be shipped in the July-September quarter, two sources directly involved in the quarterly pricing talks said on Monday.
The deal, which marks a 22-23 percent fall from a $115-117 per tonne premium PREM-ALUM-JP in the previous quarter, is the first drop in three quarters, in line with a slide in overseas surcharges for physical aluminium.
Japan is Asia's biggest importer of aluminium and the premiums for primary metal shipments it agrees to pay each quarter over the London Metal Exchange (LME) cash price CMAL0 set the benchmark for the region.
