China Launches CV Duty Investigation Into US Polyphenylene

China began a countervailing duty investigation on imports of U.S. polyphenylene ether, an Aug. 14 notice said, according to an unofficial translation. China said it expects to complete the investigation by Aug. 14, 2021. The country recently launched an antidumping duty investigation into the same imports from the U.S. (see 2008030018).
