WASHINGTON (From the News Tribune) -- The U.S. International Trade Commission on Tuesday moved to crack down on the illegal dumping of foreign government-subsidized uncoated paper into the U.S. marketplace.

The agency ruled that China, Brazil, Indonesia, Australia and Portugal have violated U.S. trade laws and "materially injured" U.S. paper manufacturers by dumping uncoated paper into the United States "at less than fair market value."

All six commissioners voted in favor of the ruling, backing the U.S. Department of Commerce's preliminary ruling last year.

The decision means that the Department of Commerce will now issue anti-dumping and countervailing orders on uncoated paper from the five countries, assessing duties on uncoated paper from those nations.

The United Steelworkers Union, Packaging Corporation of America, Domtar Corporation, Finch Paper and Glatfelter Company jointly filed the original anti-dumping complaints.
