Papers
We are the largest integrated manufacturer and marketer of uncoated freesheet paper in North America and the second largest in the world based on production capacity. We have 10 pulp and paper mills in operation (eight in the United States and two in Canada) with an annual paper production capacity of approximately 3.9 million tons of uncoated freesheet paper, after giving effect to the conversion of our Plymouth facility to 100% fluff pulp production in 2010. In addition, we have an annual production capacity of 238,000 tons of coated groundwood at our Columbus paper mill. Approximately 81% of our paper production capacity is domestic and the remaining 19% is located in Canada. Our paper manufacturing operations are supported by 15 converting and distribution operations, including a network of 12 plants located offsite of our paper making operations. Also, we have forms manufacturing operations at three of the offsite converting and distribution operations and two stand-alone forms manufacturing operations.
In addition, we manufacture and sell pulp in excess of our internal requirements, and we purchase papergrade pulp from third parties allowing us to optimize the logistics of our pulp capacity while reducing transportation costs. We have the capacity to sell approximately 1.6 million metric tonnes of pulp per year depending on market conditions, after giving effect to the conversion of our Plymouth facility to 100% fluff pulp production in 2010. Approximately 51% of our trade pulp production capacity is domestic, and the remaining 49% is located in Canada. We produce market pulp at our two non-integrated pulp mills in Kamloops and Dryden, as well as at our pulp and paper mills in Espanola, Ashdown, Hawesville, and Windsor. We also produce pulp at our Plymouth mill.
