SQM ANNOUNCES PRICE INCREASE IN IODINE SQM announced that effective October 1st, 2008, or as contracts permit, the Company has increased the price of iodine by 25%. Increasing global demand, mainly driven by X-ray contrast media and LCD polarizing film applications, combined with lower than expected supply from other players in the industry, have reduced the availability of iodine in the market. These conditions explain the price increase.
