U.S. Department of Commerce Concludes Antidumping Review for PET Film from Taiwan
Estimated reading time: 4–6 minutes
The U.S. Department of Commerce (Commerce) has announced the final results of its antidumping duty administrative review concerning polyethylene terephthalate film, sheet, and strip (PET film) from Taiwan. The period of review (POR) for this investigation was from July 1, 2023, through June 30, 2024. The department has determined that these products were sold in the United States at less than normal value.
Background of the Investigation
Commerce initially published the Preliminary Results on October 3, 2025, and invited interested parties to comment. Due to unforeseen events like the Federal Government shutdown, which caused a delay in proceedings, Commerce extended its deadlines. The final results were due on April 7, 2026.
The review was based on the period specified, examining entries of PET film from Taiwan. Commerce reviewed comments and documents submitted by interested parties before reaching its final decisions.
Final Decisions and Rescission of Review
Commerce decided to rescind part of its review regarding entries from Shinkong Materials Technology Corporation and Shinkong Synthetic Fiber Corporation. The review found no entries of PET film from these entities during the POR for which duties could be assessed. Therefore, as there were no entries, the review was partially rescinded in accordance with the law.
Final Results of the Review
Commerce has concluded that Nan Ya Plastics Corporation, a producer/exporter, sold PET film in the U.S. at a weighted-average dumping margin of 1.06 percent. Commerce will now calculate and apply antidumping duties on the entries of subject merchandise based on these findings.
Details for Importers
Importers need to act in accordance with Commerce’s decision to file appropriate certificates regarding the reimbursement of antidumping duties. Failure to comply may result in double antidumping duties being assessed.
Cash Deposit and Assessment Rates
Following this notice’s publication, new cash deposit requirements will apply to shipments of PET film from Taiwan entered into the U.S. The cash deposit rate for companies covered by this review will reflect the final dumping margin. For companies not covered, the previous rates from completed segments will remain in effect.
Commerce will provide detailed instructions to the U.S. Customs and Border Protection for the assessment of duties. These instructions will be sent no earlier than 35 days after this notice’s publication to provide parties an opportunity to seek an injunction if necessary.
This announcement completes the administrative review in accordance with U.S. trade law, solidifying the process by which the U.S. monitors and enforces fair trade practices regarding imported goods.
