SUBSCRIBER NOTE: Platts to assess ex-works China alumina basis Shanxi

Following a period of industry feedback, Platts will assess its current daily China spot alumina price (MMXCY00) basis ex-works Shanxi province, beginning December 1, 2015. The assessment is currently basis ex-works Henan province. Shanxi province is now the most active spot market for China domestic alumina trade, while Henan's focus has turned to mainly captive consumption within the province, and term contract trades. Market participants have provided feedback that Shanxi spot alumina trade is most representative of the current market. In response, Platts will publish the China daily spot alumina price basis ex-works Shanxi, as well as the related automated weekly average (MMXCY04) and monthly average (MMXCY03) prices, effective December 1, 2015. Platts will normalize all price information gathered from other major alumina-producing Chinese provinces -- Henan, Shandong, Guangxi, and Guizhou -- back to an ex-works Shanxi basis. Any further questions and feedback should be directed to joanna.lim@platts.com; yuencheng.mok@platts.com; and pricegroup@platts.com.
