This document is the preliminary determination by the U.S. International Trade Commission regarding antidumping and countervailing duty investigations of certain polyethylene terephthalate resin from Canada, China, India, and Oman. The Commission found a reasonable indication that the U.S. PET resin industry is materially injured by reason of imports of PET resin from the subject countries that are allegedly sold at less than fair value and subsidized. The Commission based this determination on the record developed during the preliminary phase of the investigations.
