TOKYO, Sept 30 (Reuters) - Japan's aluminium premium for shipments during the October to December quarter was set at $75 per tonne, reflecting softer spot premiums, five sources directly involved in the quarterly pricing talks said.
The deal, which marks a 17 to 19 percent fall from the $90 to $93 per tonne premiums PREM-ALUM-JP in the previous quarter, is the second straight quarterly drop and the lowest in more than seven years.
Japan is Asia's biggest importer of aluminium and the surcharges, or premiums, which consumers pay on top of the London Metal Exchange cash price CMAL0 for primary metal shipments, set the benchmark for the region.
