Now Open: Antidumping Review on Adipic Acid
In brief
Brazil’s Foreign Trade Secretariat (SECEX) initiated the review of the antidumping measures applied to Brazilian imports of adipic acid (NCM 2917.12.10) originating from Germany, China, United States, France, and Italy.
Adipic acid is widely used in the production of polyurethanes, plasticizers such as dioctyl adipate, and polyamides, including nylon salt, which is employed in engineering plastics as well as textile and industrial yarns.
The investigation may result in the extension of the antidumping duties for an additional five years, thereby maintaining the cost of Brazilian imports of the investigated product at higher levels.
The importance of stakeholder participation
The active participation of importers, exporters, and any other interested parties in the investigation may be decisive in ensuring a final determination that is more favorable to the interested party concerned. Interested parties may request admission to the proceedings by April 20, 2026 [1], provided they demonstrate the extent to which they may be affected by the possible extension of the duty.
