Chemtura Increases Prices on Organotin Stabilizers

Effective September 1, 2008, or as contract terms allow, Chemtura Corporation(NYSE:CEM) will increase the base price of its organotin stabilizers globally by 6%. Previously announced increases have scarcely kept pace with the unprecedented escalation in tin metal prices, and, indeed, tin remains at historically high levels. While tin is a major component of organotin stabilizers, the cost of other raw materials such as energy, oil derivatives and sulfur, have also escalated dramatically. The increase is therefore necessary to offset the cost of these "non tin” raw materials. Chemtura has worked closely with customers to minimize the impact of this extraordinary raw materials inflation. However, it is essential to implement price increases to cover inflation in order to remain as a reliable supplier for the long term. Chemtura remains committed to the tin stabilizer industry and will continue to strive to provide customers with the best possible value.
