US Anti-Dumping Duty on Korean Acrylates & Methacrylates
The US International Trade Commission has issued a final anti-dumping determination on multifunctional acrylate and methacrylate monomers and oligomers imported from South Korea. The decision concludes the investigation and establishes duties on these chemicals, which are used in coatings, adhesives, and specialty polymers. Importers of these products from South Korea must now account for anti-dumping tariffs in landed-cost calculations.

On 5 June 2026, the US Federal Register published the final anti-dumping determination for multifunctional acrylate and methacrylate monomers and oligomers sourced from South Korea. This supplemental schedule marks the conclusion of the Department of Commerce investigation and establishes binding duties on these chemical imports.
Product scope and HS classification
The investigation covers multifunctional acrylate and methacrylate monomers and oligomers from South Korea. These specialty chemicals fall primarily under HS Chapter 39 (plastics and articles thereof), with some overlap into Chapter 29 (organic chemicals) depending on specific molecular structure and end use. The products are widely used in UV-curable coatings, adhesives, sealants, inks, and the manufacture of specialty polymers.
What this means for shippers
All importers bringing multifunctional acrylate and methacrylate monomers and oligomers from South Korea into the US must immediately apply the anti-dumping duty rates published in this final determination. Failure to declare and deposit the correct duty at import will result in liquidation adjustments and potential penalties. Review your supplier's country of origin and product HS classification now—if your material originates in South Korea and fits the product definition, your landed cost and pricing models require an urgent update. Use our anti-dumping lookup to confirm the exact duty rate and HS chapters affected.
