SUBSCRIBER NOTE: Platts uses Japan spot aluminum premium to calculate China all-in price

Effective November 1, 2017, S&P Global Platts will use the daily Japan spot aluminum premium assessment (MMANA00) as a component to calculate its daily China all-in aluminum price in yuan/mt (MMBAB00) and $/mt (MMBAA00). The China prices were previously using the weekly South Korean aluminum premium (MMAMX00) for the calculation. The final publication of the China price using the South Korean premium was on October 31, 2017. This change follows a period of industry feedback and notification, which affirmed earlier Platts research that the Japan spot premium is the more recognized benchmark for aluminum trades in Asia.
