【Premium for Japanese port primary aluminum in Q3 may reach US$175/ton】According to foreign media, three insiders directly involved in quarterly pricing negotiations said on Wednesday that a global aluminum producer has proposed a premium of US$175 per ton for primary metal shipments in July-September to Japanese buyers, an increase of 18%-21% from this quarter. Japan is a major importer of light metals in Asia, and its agreement to pay a premium higher than the cash price of the London Metal Exchange (LME) for primary metal shipments each quarter sets a benchmark for the region. In the April-June quarter, Japanese buyers agreed to pay a premium of US$145-148 per ton for PREM-ALUM-JP, an increase of 61%-64% from the previous quarter.
