On February 12, 2026, the Korea Trade Commission issued a preliminary affirmative ruling in this case and requested the Ministry of Economy and Finance to impose provisional anti-dumping duties.

On April 22, 2026, the Ministry of Economy and Finance of Korea officially implemented provisional anti-dumping duties, with tax rates ranging from 9.53% to 19.17%, which remained in effect until the issuance of this final ruling.

III. Brief Analysis of the Impact on sector Exports

Butyl Acrylate is a core chemical raw material among acrylates and is broadly utilized in downstream industries such as coatings, adhesives, and emulsions. Once the five-year anti-dumping duties officially take effect, the export costs to relevant domestic companies to Korea will rise, and the export competitiveness of some companies will be weakened. Domestic manufacturers might adjust their export directions and explore other overseas markets to hedge against the trade barriers in the Korean market.
