On July 9, 2019 three firms (Advanced Extrusion, Inc., Ex-Tech Plastics, Inc., and Multi-Plastics Extrusions, Inc.) filed petitions seeking the imposition of antidumping duties on polyethylene terephthalate (PET) sheet from Korea, Mexico, and Oman. Subject goods are currently classified under HTSUS 3920.62.0090. 

On September 10, 2019 the United States International Trade Commission determined that there is a reasonable indication that a U.S. industry is materially injured by reason of these imports from Korea and Oman, but that imports of this product from Mexico are negligible. The U.S. Department of Commerce will therefore continue with its antidumping duty investigations concerning imports of this product from Korea and Oman, but the commission's finding terminated the investigation concerning Mexico.

On February 26, 2020 the U.S. Department of Commerce announced affirmative preliminary determinations in the antidumping duty investigations of imports of from Korea and Oman. Commerce preliminarily determined that exporters from Korea have dumped PET sheet in the United States at margins ranging from 8.02 to 52.01 percent, and that exporters from Oman have dumped PET sheet in the United States at a margin of 2.78 percent. As a result of today’s decision, Commerce will instruct U.S. Customs and Border Protection to collect cash deposits from importers of PET sheet from Korea and Oman based on the preliminary rates noted above.
