Commerce Releases Preliminary Results for Korean Low Melt Polyester Staple Fiber Review
Estimated reading time: 5–7 minutes
The U.S. Department of Commerce has released preliminary results in the 2023–2024 administrative review of the antidumping duty order on low melt polyester staple fiber (low melt PSF) from the Republic of Korea.
The review covers the period from August 1, 2023, to July 31, 2024.
Toray Advanced Materials Korea, Inc. (TAK), the sole producer and exporter examined in this review, was determined to have sold low melt PSF in the United States at prices below normal value during this period.
Commerce preliminarily determined a weighted-average dumping margin of 3.02 percent for TAK.
Background
The original antidumping duty order on low melt PSF from Korea was published on August 16, 2018 (83 FR 40752).
On August 1, 2024, Commerce opened the opportunity for interested parties to request an administrative review (89 FR 62714).
Following timely requests, Commerce initiated a review on September 20, 2024 (89 FR 77079).
Throughout the review process, multiple extensions and tolling of deadlines were issued:
- December 9, 2024: All deadlines tolled for 90 days.
- June 17, 2025: Deadline extended by 120 days to December 1, 2025.
- November 14, 2025: Deadlines tolled by 47 days due to a federal government shutdown.
- November 24, 2025: Deadlines tolled an additional 21 days due to a backlog in document processing.
The new deadline for preliminary results was set as February 5, 2026.
Scope of the Review
The merchandise covered is synthetic staple fibers that are not carded or combed.
They are specifically bi-component polyester fibers with one component that melts at a lower temperature.
Commerce’s Methodology
Commerce conducted the review under sections 751(a)(1)(B) and (2) of the Tariff Act of 1930.
Export price and normal value were calculated using sections 772 and 773, respectively.
The full description of the methodology is available in the Preliminary Decision Memorandum.
Public Comment Information
Interested parties may submit case briefs no later than 21 days following publication.
Rebuttal briefs are due five days after the deadline for case briefs.
Each brief must include a table of contents and authorities.
Commerce asks parties to submit concise public summaries of each argument—limited to 450 words, excluding citations.
Hearing requests must be filed within 30 days of publication.
They must include the requester’s contact details, number of participants, and list of discussion topics.
If a hearing is granted, Commerce will announce the date and time.
All submissions must be filed through ACCESS, the department’s electronic platform.
Final Determination and Assessment
Commerce intends to publish the final results within 120 days of this notice.
Antidumping duties will be assessed by U.S. Customs and Border Protection (CBP) based on importer-specific rates.
If the weighted-average margin or assessment rate is zero or de minimis (below 0.50 percent), duties will not be collected.
Where TAK did not know the destination of the U.S. entries, Commerce will instruct CBP to assess duties at the all-others rate of 16.27 percent, unless a rate for the intermediate company exists.
Cash Deposit Instructions
After the final results:
- If TAK’s final margin is above 0.50 percent, that rate becomes the new deposit rate.
- If below 0.50 percent, the rate becomes zero.
- If the exporter was not reviewed, but the producer was, that producer’s most recent rate applies.
- If neither was reviewed, the all-others rate of 16.27 percent will remain in effect.
Importer Responsibility
Importers must comply with 19 CFR 351.402(f)(2) by filing reimbursement certificates before liquidation.
Failure to do this may lead Commerce to presume reimbursement occurred and apply double duties.
Next Steps
Commerce will issue instructions to CBP within 35 days of final results publication, unless legal action delays the process.
