Notice
Summary
The U.S. Department of Commerce fixed some math and clerical mistakes in its early decision about certain chemicals (monomers and oligomers) imported from South Korea. This change confirms that these products were sold for less than their fair value during 2024, which could mean extra duties for Korean exporters. The update kicks in starting February 6, 2026, affecting companies like Arkema Inc. and others involved in this trade.
Analyzed Economic Effects
3 provisions identified: 0 benefits, 3 costs, 0 mixed.
Amended Dumping Margins Announced

These amended margins are part of the amended preliminary determination published February 6, 2026.
Cash Deposit Requirement Increased
The collection of cash deposits and suspension of liquidation for imports of the covered monomers and oligomers from Korea will be revised to reflect the amended preliminary rates, and the increased cash deposit rate is effective on the date this notice published, February 6, 2026.
