Commerce Probes Cheap Korean and Taiwanese Chemicals Dumping in US Markets
Published Date: 4/23/2025
Notice
Summary
The U.S. is starting investigations to see if certain chemicals called monomers and oligomers from South Korea and Taiwan are being sold unfairly cheap in the U.S. This affects companies importing these products and could lead to extra taxes to protect American makers like Arkema, Inc. The process kicked off on April 16, 2025, so changes and possible costs might come soon.
Analyzed Economic Effects
3 provisions identified: 1 benefits, 1 costs, 1 mixed.
Antidumping Probe Could Mean New Import Duties
The Department of Commerce initiated antidumping (less‑than‑fair‑value) investigations on April 16, 2025 into certain monomers and oligomers from the Republic of Korea and Taiwan. The petitioner reported estimated dumping margins of 137.84–188.01 percent for Korea and 112.81–286.12 percent for Taiwan, and Commerce will make preliminary determinations no later than 140 days after initiation. If duties are imposed, U.S. importers of the in‑scope products could face additional import charges tied to these investigations.
Domestic Producer Petition Gains Traction
Arkema, Inc. filed the petitions on March 27, 2025 on behalf of the U.S. domestic industry, and Commerce found that the petitioner demonstrated sufficient industry support to initiate the investigations. Because Commerce determined the petitions meet statutory requirements, domestic producers who supported the petition may obtain trade relief if investigations end affirmatively.
Which Products and Entries Are Covered
The investigations cover specified monomers and oligomers listed with CAS numbers and HTSUS subheadings (e.g., 2916.12.5050, 2916.14.2050, 3824.99.2900, 3907.29.0000, 3907.30.0000) and include blends or mixtures that contain at least 20 percent by weight of in‑scope products. Downstream products such as inks, coatings, and overprint varnishes are expressly excluded from the scope.
