1. On 06/11/2025 Commerce published in the Federal Register its antidumping duty order on certain alkyl phosphate esters from the People's Republic of China (China) (90 FR 24579). 2. The merchandise covered by the scope of this order are alkyl phosphate esters, which are halogenated and non-halogenated phosphorus-based esters with a phosphorus content of at least 6.5 percent (per weight) and a viscosity between 1 and 2000 mPa.s (at 20-25 °C). Merchandise subject to this order primarily includes Tris (2-chloroisopropyl) phosphate (TCPP), Tris(1,3-dichloroisopropyl) phosphate (TDCP), and Triethyl Phosphate (TEP). TCPP is also known as Tris (1-chloro-2-propyl) phosphate, Tris (1-chloropropan-2-yl) phosphate, Tris (monochloroisopropyl) phosphate (TMCP), and Tris (2-chloroisopropyl) phosphate (TCIP). TCPP has the chemical formula C9H18Cl3O4P and the Chemical Abstracts Service (CAS) Nos. 1244733-77-4 and 13674-84-5. It may also be identified as CAS No. 6145-73-9. TDCP is also known as Tris (1,3-dichloroisopropyl) phosphate, Tris (1,3-dichloro-2-propyl) phosphate, Chlorinated tris, tris {2- chloro-1-(chloromethyl ethyl)} phosphate, TDCPP, and TDCIPP. TDCP has the chemical formula C9H15Cl6O4P and the CAS No. 13674-87-8. TEP is also known as Phosphoric acid triethyl ester, phosphoric ester, flame retardant TEP, Tris(ethyl) phosphate, Triethoxyphosphine oxide, and Ethyl phosphate (neutral). TEP has the chemical formula (C2H5O)3PO and the CAS No. 78-40-0. Imported alkyl phosphate esters are not excluded from the scope of this order even if the imported alkyl phosphate ester consists of a single isomer or combination of isomers in proportions different from the isomers ordinarily provided in the market. Also included in this investigation are blends including one or more alkyl phosphate esters, with or without other substances, where the alkyl phosphate esters account for 20 percent or more of the blend by weight. Alkyl phosphate esters are classified under subheading 2919.90.5050, Harmonized Tariff Schedule of the United States (HTSUS). Imports may also be classified under subheadings 2919.90.5010 and 3824.99.5000, HTSUS. The HTSUS subheadings and CAS registry numbers are provided for convenience and customs purposes. The written description of the scope is dispositive. 3. For imports of certain alkyl phosphate esters from China, CBP shall suspend liquidation of entries of subject merchandise entered, or withdrawn from warehouse, for consumption on or after 06/06/2025 (date of publication of the International Trade Commission final determination in the Federal Register). Effective 06/06/2025, CBP shall require a cash deposit equal to the percentages identified below. These cash deposit rates have been adjusted to reflect the appropriate subsidy offsets determined in the companion countervailing duty proceeding.
