According to the May 2008 ISM Manufacturing Report on Business (ROB) released on June 2, there were 30 commodities that registered higher prices in the last month. New additions to the list included acrylics, additives, phosphoric acid. On its 7-month trek of higher prices, sulfuric acid is also now in short supply, along with steel and caustic soda. Methanol did, however, drop in price for the second straight month.
