**SUPPLEMENTARY INFORMATION:**
Effective May 6, 2025, the Commission established a general schedule for the conduct of the final phase of its countervailing duty and antidumping duty investigations on hexamethylenetetramine (“hexamine”) from China, Germany, India, and Saudi Arabia (90 FR 21948, May 22, 2025, and as revised in 90 FR 31241, July 14, 2025), following preliminary determinations by the U.S. Department of Commerce (“Commerce”) that imports of hexamine from China were being subsidized by the government of China (90 FR 19182, May 6, 2025) and that imports of hexamine from China were being sold in the United States at less than fair value (90 FR 11508, March 7, 2025). Notice of the scheduling of the final phase of the Commission's investigations and of a public hearing held in connection therewith was given by posting copies of the notice in the Office of the Secretary, U.S. International Trade Commission, Washington, DC, and by publishing the notice in the *Federal Register* on May 22, 2025 (90 FR 21948). The Commission conducted its hearing on July 18, 2025. All persons who requested the opportunity were permitted to participate.
Commerce has issued final affirmative countervailing duty and antidumping duty determinations with respect to hexamine from China (90 FR 33923 and 33922, July 18, 2025). The Commission subsequently issued its final determinations that an industry in the United States was materially injured by reason of imports of hexamine from China provided for in subheading 2933.69.50 of the Harmonized Tariff Schedule of the United States (“HTSUS”) that have been found by Commerce to be subsidized by the government of China and sold in the United States at less than fair value (90 FR 43234, September 8, 2025).
Commerce has issued final affirmative countervailing duty determinations with respect to imports of hexamine from India (90 FR 45720, September 23, 2025) and antidumping duty determinations with respect to imports of hexamine from Germany, India, and Saudi Arabia (90 FR 45728, 45725, and 45723, September 23, 2025). Accordingly, the Commission is currently issuing a supplemental schedule for its countervailing duty investigation on imports of hexamine from India and its antidumping duty investigations on imports of hexamine from Germany, India, and Saudi Arabia.
This supplemental schedule is as follows: the deadline for filing supplemental party comments on Commerce's final countervailing duty and antidumping duty determinations is 5:15 p.m. on October 3, 2025. Supplemental party comments may address only Commerce's final countervailing duty determinations regarding imports of hexamine from India and Commerce's final antidumping duty determinations regarding imports of hexamine from Germany, India, and Saudi Arabia. These supplemental final comments may not contain new factual information and may not exceed five (5) pages in length. The supplemental staff report in the final phase of the current investigations will be placed in the nonpublic record on October 17, 2025, and a public version will be issued thereafter.
For further information concerning this proceeding see the Commission's notice cited above and the Commission's Rules of Practice and Procedure, part 201, subparts A and B (19 CFR part 201), and part 207, subparts A and C (19 CFR part 207).
Additional written submissions to the Commission, including requests pursuant to section 201.12 of the Commission's rules, shall not be accepted unless good cause is shown for accepting such submissions, or unless the submission is pursuant to a specific request by a Commissioner or Commission staff.
In accordance with sections 201.16(c) and 207.3 of the Commission's rules, each document filed by a party to the investigations must be served on all other parties to the investigations (as identified by either the public or BPI service list), and a certificate of service must be timely filed. The Secretary will not accept a document for filing without a certificate of service.
Please note the Secretary's Office will accept only electronic filings during this time. Filings must be made through the Commission's Electronic Document Information System (EDIS, *https://edis.usitc.gov.* ) No in-person paper-based filings or paper copies of any electronic filings will be accepted until further notice.
