SUBSCRIBER NOTE: Platts assesses ex-works China alumina basis Shanxi

Effective December 1, 2015, Platts has begun assessing its daily China spot alumina price (MMXCY00) basis ex-works Shanxi province. The assessment was previously basis ex-works Henan province. The related automated weekly average (MMXCY04) and monthly average (MMXCY03) prices for this series also are basis Shanxi effective December 1, 2015. The change to Shanxi basis follows a period of industry feedback and notification. The last price assessment basis Henan was published on November 30, 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.
