Commerce Issues Duties on Korean Monomers and Oligomers – Yawn
Published Date: 7/28/2026
Notice
Summary
Based on affirmative final determinations by the U.S. Department of Commerce (Commerce) and the U.S. International Trade Commission (ITC), Commerce is issuing an antidumping duty (AD) order on certain monomers and oligomers (monomers and oligomers) from the Republic of Korea (Korea).
Analyzed Economic Effects
4 provisions identified: 2 benefits, 2 costs, 0 mixed.
Antidumping Duties Apply Since Jan 5
If you import the covered monomers and oligomers from Korea, antidumping duties will be assessed on unliquidated entries entered or withdrawn for consumption on or after January 5, 2026. Commerce will direct U.S. Customs and Border Protection to assess duties equal to the amount by which the normal value exceeds the export price, and suspension of liquidation and cash deposit requirements will be reinstituted effective on the date of publication of the ITC’s final injury determination (applicable July 28, 2026).
Specific Dumping Margins Set for Exporters
Commerce set estimated weighted-average dumping margins for subject Korean producers: Green Chemical Co., Ltd. and the all-others rate at 65.72 percent, and Miwon Specialty Chemical Co., Ltd. and Kukdo Chemicals Co. Ltd. at 155.42 percent (rates for Miwon and Kukdo are based on facts available with adverse inferences). These margins are the basis for required cash deposits and duties.
Refund of Deposits for Oct 7, 2025–Jan 5, 2026
Because the ITC found critical circumstances do not exist, Commerce intends to instruct CBP to lift the suspension of liquidation and to refund all cash deposits for entries of subject merchandise entered or withdrawn for consumption on or after October 7, 2025 and before January 5, 2026. Importers with entries in that date range will receive refunds of deposited estimated antidumping duties.
No Duties for Entries July 4–July 27, 2026
Commerce intends to instruct CBP to terminate the suspension of liquidation for the extended provisional measures period that ended July 3, 2026, and to liquidate, without regard to antidumping duties, unliquidated entries entered or withdrawn for consumption on or after July 4, 2026 through July 27, 2026 (the day before publication of the ITC's final injury determination in the Federal Register). Importers with entries in that window will not have duties applied to those entries.
