Taiwan PET film dumped low, duties may rise.
Published Date: 10/2/2026
Notice
Summary
The U.S. Department of Commerce found that Nan Ya Plastics sold PET film from Taiwan at unfairly low prices from July 2024 to June 2025. Meanwhile, Shinkong companies didn’t have any sales to review during this time. This means some antidumping duties might change soon, and companies involved should pay close attention to upcoming updates and deadlines.
Analyzed Economic Effects
6 provisions identified: 1 benefits, 4 costs, 1 mixed.
Importer certificate to avoid double duties
Importers are reminded of their duty to file a certificate regarding the reimbursement of antidumping duties under 19 CFR 351.402(f)(2) prior to liquidation of relevant entries; failing to file this certificate could lead Commerce to presume reimbursement occurred and result in the assessment of double antidumping duties.
Nan Ya preliminarily found to be dumping
Commerce preliminarily found that Nan Ya Plastics sold PET film from Taiwan at less than normal value for the period July 1, 2024 through June 30, 2025, and calculated a weighted-average dumping margin of 3.95 percent for Nan Ya.
How antidumping duties will be assessed
If Nan Ya’s final weighted-average dumping margin is not zero or de minimis (i.e., not less than 0.5 percent) for July 1, 2024 through June 30, 2025, Commerce will calculate importer-specific assessment rates based on the ratio of total dumping to entered value; if the final margin or an importer-specific rate is zero or de minimis, Commerce will instruct CBP to liquidate the appropriate entries without regard to antidumping duties.
Cash deposit rules after final results
Effective for shipments of PET film from Taiwan entered, or withdrawn from warehouse, for consumption on or after the date of publication of the final results of this administrative review: (1) Nan Ya’s cash deposit rate will be the rate in the final results (unless the rate is zero or de minimis, in which case no deposit is required); (2) previously reviewed or investigated companies keep their most recent company-specific rate; (3) if an exporter is not covered but the manufacturer is, the deposit rate will be the manufacturer’s most recent rate; and (4) the cash deposit rate for all other producers/exporters is 2.40 percent.
Review rescinded for Shinkong companies
Commerce preliminarily found that Shinkong Materials Technology Corporation and Shinkong Synthetic Fiber Corporation (treated as one entity) had no suspended entries of PET film during July 1, 2024 through June 30, 2025, and intends to rescind the administrative review for those companies for that period.
Liquidation at 'all-others' rate for certain entries
For entries during July 1, 2024 through June 30, 2025 that were produced by Nan Ya but for which Nan Ya did not know the merchandise was destined for the United States, Commerce intends to instruct CBP to liquidate those entries at the all-others rate of 2.40 percent if there is no rate for any intermediate company in the transaction.
