Message body

Full text as published by U.S. Customs and Border Protection

1. On 01/10/2025, Commerce published in the Federal Register its initiation of the countervailing duty investigation of erythritol from the People's Republic of China (90 FR 1962). The effective date of this initiation is 01/02/2025 (the applicable date stated in the FR notice). 2. The product within the scope of this investigation is erythritol, which is a sugar alcohol, commonly referred to as a polyol, typically produced by the fermentation of glucose using enzymes and yeast or yeast-like fungi (though the scope includes erythritol produced using any other feedstock or organism). Erythritol is an organic compound with the molecular formula C4H10O4 and a Chemical Abstracts Service (CAS) registry number of 149-32-6. Other names for erythritol include meso-erythritol, (2R, 3S)-butan-1,2,3,4-tetrol, butane-1,2,3,4-tetrol, or meso-1,2,3,4-Tetrahydryoxybutane. Erythritol typically appears as a white crystalline, odorless product that rapidly dissolves in water. While erythritol is typically produced in the crystalline form or as a fine powder or in directly compressible form, the scope of this investigation covers all physical forms and grades of erythritol, including organic erythritol. The merchandise covered by this investigation is classifiable under Harmonized Tariff Schedule of the United States (HTSUS) subheading 2905.49.4000. Erythritol may also enter under HTSUS subheading 2106.90.9998. Although the HTSUS subheadings are provided for convenience and customs purposes, the written description of the merchandise covered by this investigation is dispositive. 3. This proceeding has been assigned case number C-570-193. 4. If there are any questions by the importing public regarding this message, please contact the Call Center for the Office of AD/CVD Operations, Enforcement and Compliance, International Trade Administration, U.S. Department of Commerce at (202) 482-0984. CBP ports should submit their inquiries through authorized CBP channels only. (This message was generated by OIX:AKM.) 5. There are no restrictions on the release of this information.
