1. On 07/20/2026, Commerce published in the Federal Register its initiation of the antidumping duty investigation of certain choline salts from the People's Republic of China (91 FR 45241). The effective date of this initiation is 07/14/2026 (the applicable date stated in the FR notice). 2. The merchandise covered by this investigation is certain choline salts, in all forms and purities, that are capable of delivering the nutrient choline. Subject choline salts may or may not contain additives such as a vegetable or mineral carrier or an anti-caking agent and may or may not be coated or encapsulated, such as in a lipid. For choline salts that contain non-choline salt components, such as a carrier or coating, the entire article is covered, including the non-choline salt content, provided that the choline salt content constitutes at least 30 percent by weight. Choline salts are organic compounds and quaternary ammonium salts. Subject merchandise includes, but is not limited to, the following choline salts in their aqueous, crystallized, dried, or encapsulated forms: Choline chloride, which exists as a colorless aqueous solution and as a white, crystalline powder which may or may not be mixed with vegetable, inorganic, or fat-based carriers. It has the molecular formula [(CH3)3NCH2CH2OH]+Cl-. It may also be referred to as (2-hydroxyethyl) trimethylammonium chloride, and its molecular formula may also be expressed as C5H14NO.Cl or C5H14ClNO. The Chemical Abstracts Service (CAS) registry number for choline chloride is 67-48-1; the Flavoring Extract Manufacturers' Association (FEMA) number is 4500; the PubChem number is 6209; and the European Community (EC) number is 200-655-4; Choline bitartrate, which is a white crystalline powder with the molecular formula (CH3)3NCH2CH2OH+HOOC−CH(OH)−CH(OH)−COO−. It may be referred to as (2-hydroxyethyl) trimethylammonium-L-(+)-tartrate salt, and its molecular formula may also be expressed as C5H14NO.C4H5O6 or C9H19NO7. Choline bitartrate has the CAS registry number 87-67-2; the PubChem number 6900; and the EC number 201-763-4; Choline dihydrogen citrate, which is a white crystalline powder with the molecular formula C11H21NO8 and may be referred to as (2-hydroxyethyl) trimethylammonium citrate. Choline dihydrogen citrate has the CAS registry number 77-91-8; the PubChem number 66170; and the EC number 201-068-6. This investigation covers choline salts for which the reaction of trimethylamine and ethylene oxide occurs in the subject country. The merchandise subject to this investigation includes choline salts in their aqueous or dried form that are processed in a third country, including, but not limited to, refining, drying, encapsulating, blending, or any other processing that would not otherwise remove the merchandise from the scope of this investigation if performed in the country of manufacture of the in-scope choline salt. Choline salts subject to this investigation are not excluded when commingled with choline salts from sources not subject to this investigation. Only the subject component of such commingled products is covered by the scope of this investigation. Excluded from the scope of this investigation is choline hydroxide, which has the molecular formula C5H15NO2, the CAS registry number 123-41-1, the PubChem number 31255, and the EC number 204-625-1. Also excluded is choline salicylate, which has the molecular formula C12H19NO4, the CAS registry number 2016-36-6, the PubChem number 54686350, and the EC number 217-948-8. Also excluded from the scope of the investigation are any products already covered by the scope of any extant antidumping and/or countervailing duty orders, including 2,4-Dichlorophenoxyacetic Acid from India and the People's Republic of China: Antidumping Duty Orders, 90 FR 22243 (May 27, 2025), and including 2,4-Dichlorophenoxyacetic Acid from the People's Republic of China and India: Countervailing Duty Orders, 90 FR 22232 (May 27, 2025). The choline salts subject to this investigation are classified under the Harmonized Tariff Schedule of the United States (HTSUS) subheading 2923.10.0000. Subject choline salts of dried choline chloride may also enter under HTSUS subheadings 2309.90.1005, 2309.90.1015, 2309.90.1020, 2309.90.1030, 2309.90.1032, 2309.90.1035, 2309.90.1045, 2309.90.1050, 2309.90.9500, and 3824.99.9397. Although the HTSUS subheadings and CAS registry numbers are provided for convenience and customs purposes, the written description of the scope of this investigation is dispositive. 3. This proceeding has been assigned case number A-570-238. 4.
