USITC Votes to Continue Investigations on 2,4-Dichlorophenoxyacetic Acid (“2,4-D”) from China and India

The United States International Trade Commission (USITC) today determined that there is a reasonable indication that a U.S. industry is materially injured by reason of imports of 2,4-dichlorophenoxyacetic acid (“2,4-D”) from China and India that are allegedly sold in the United States at less than fair value and subsidized by the governments of China and India.

Chairman David S. Johanson and Commissioners Rhonda K. Schmidtlein, Jason E. Kearns, and Amy A. Karpel voted in the affirmative. 

As a result of the Commission’s affirmative determinations, the U.S. Department of Commerce will continue its investigations of imports of 2,4-D from China and India, with its preliminary countervailing duty determinations due on or about June 27, 2024, and its preliminary antidumping duty determinations due on or about September 10, 2024.

The Commission’s public report 2,4-Dichlorophenoxyacetic Acid (“2,4-D”) from China and India (Inv. Nos. 701-TA-710-711 and 731-TA-1673-1674 (Preliminary), USITC Publication 5511, May 2024) will contain the views of the Commission and information developed during the investigations.

The report will be available by June 7, 2024; when available, it may be accessed on the USITC website at:

2,4-Dichlorophenoxyacetic Acid (“2,4-D”) from China and India

Investigation Nos. 701-TA-710-711 and 731-TA-1673-1674 (Preliminary)

Product Description: The merchandise covered by these investigations is 2,4-dichlorophenoxyacetic acid (“2,4-D”) and its derivative products, including salt and ester forms of 2,4-D. The end use is as an herbicide with action against a variety of broadleaf weeds, but not grasses. 2,4-D has the Chemical Abstracts Service (CAS) registry number of 94-75-7 and the chemical formula C8H6Cl2O3. Salt and ester forms of 2,4-D include 2,4-D sodium salt (CAS 2702-72-9), 2,4-D diethanolamine salt (CAS 5742-19-8), 2,4-D dimethyl amine salt (CAS 2008-39-1), 2,4-D isopropylamine salt (CAS 5742-17-6), 2,4-D triisopropanolamine salt (CAS 3234180-3), 2,4-D choline salt (CAS 1048373-72-3), 2,4-D butoxyethyl ester (CAS 1929-733), 2,4-D 2-ethylhexylester (CAS 1928-43-4), and 2,4-D isopropylester (CAS 94-11-1). All 2,4-D, as well as the salt and ester forms of 2,4-D, is covered by the scope irrespective of purity, particle size, or physical form. The conversion of a 2,4-D salt or ester from 2,4-D acid, or the formulation of nonsubject merchandise with the subject 2,4-D, its salts, and its esters in the country of manufacture or in a third country does not remove the subject 2,4-D, its salts, or its esters from the scope. For any such formulations, only the 2,4-D, 2,4-D salt, and 2,4-D ester components of the mixture is covered by the scope of the investigations.
