JACKSONVILLE, Florida — Rayonier Advanced Materials (RYAM), together with the United Steel Paper and Forestry, Rubber, Manufacturing, Energy, Allied Industrial and Service Workers International Union (USW), announced the filing with the US Department of Commerce and the US International Trade Commission of parallel antidumping and countervailing duty petitions on Brazil, and an antidumping petition on Norway, concerning U.S. imports of High Purity Dissolving Pulp (HPDP). The petitions allege that Brazilian and Norwegian manufacturers are selling HPDP in the US market at unfair prices, below fair market value or based on government subsidies. …The petitions estimate dumping margins as high as 168% for Brazil and 226% for Norway. They also identify 30 Brazilian government programs that may be providing subsidies. …“Our members are seeing the devastating impact of dumped and subsidized imports in real time,” said USW Vice President Luis Mendoza.
