Scope of the measure
The product covered by these orders is hexamine from China. For a complete description of the scope of the orders, see the Appendix to this notice. AD Order On September 3, 2025, in accordance with section 735(d) of the Act, the ITC notified Commerce of its final determination that an industry in the United States is materially injured within the meaning of section 735(b)(1)(A)(i) of the Act by reason of imports of hexamine from China that are sold in the United States at LTFV. Therefore, in accordance with section 735(c)(2) and 736 of the Act, Commerce is issuing this AD order. Because the ITC determined that imports of hexamine from China are materially injuring a U.S. industry, unliquidated entries of such merchandise from China, entered or withdrawn from warehouse for consumption, are subject to the assessment of antidumping duties. Id. Therefore, in accordance with section 736(a)(1) of the Act, Commerce will direct U.S. Customs and Border Protection (CBP) to assess, upon further instruction by Commerce, antidumping duties equal to the amount by which the normal value of the merchandise exceeds the export price (or constructed export price) of the merchandise on all relevant entries of hexamine from China. Antidumping duties will be assessed on unliquidated entries of hexamine entered, or withdrawn from warehouse, for consumption on or after May 6, 2025, the date of publication of the LTFV Preliminary Determination, but will not include entries occurring after the expiration of the provisional measures period and before publication of the ITC's final injury determination, as further described below. See Hexamethylenetetramine from the People's Republic of China: Preliminary Affirmative Determination of Sales at Less Than Fair Value 90 FR 19182 (May 6, 2025) (LTFV Preliminary Determination). Continuation of Suspension of Liquidation and Cash Deposits--AD Except as noted in the ``Provisional Measures--AD'' section of this notice, Commerce intends to instruct CBP to continue to suspend liquidation on all relevant entries of hexamine from China, in accordance with section 736 of the Act. These instructions suspending liquidation will remain in effect until further notice. Commerce also intends to instruct CBP to require cash deposits equal to the estimated weighted-average dumping margin indicated in the table below, adjusted by the relevant subsidy offsets. Accordingly, effective on the date of publication in the Federal Register of the notice of the ITC's final affirmative injury determination, CBP must require, at the same time as importers would normally deposit estimated customs duties on subject merchandise, a cash deposit equal to the rates listed in the table below. Estimated Weighted-Average Dumping Margins The estimated weighted-average dumping margin is as follows: Cash deposit rate Weighted-average (adjusted for Exporter/producer dumping margin subsidy offsets) (percent) (percent) China-wide Entity * 405.19 394.65 This rate is based on adverse facts available (AFA). Provisional Measures--AD See LTFV Final Determination. Section 733(d) of the Act states that suspension of liquidation pursuant to an affirmative preliminary determination may not remain in effect for more than four months, except where exporters representing a significant proportion of exports of the subject merchandise request that Commerce extend the four-month period to no more than six months. In the underlying investigation, Commerce published the LTFV Preliminary Determination on May 6, 2025. Therefore, the four-month period beginning on the date of the publication of the LTFV Preliminary Determination ended on September 2, 2025. Pursuant to section 737(b) of the Act, the collection of cash deposits at the rates listed above will begin on the date of publication of the ITC's final injury determinations. Therefore, in accordance with section 733(d) of the Act, Commerce will instruct CBP to terminate the suspension of liquidation and to liquidate, without regard to antidumping duties, unliquidated entries of hexamine from China entered, or withdrawn from warehouse, for consumption on or after September 3, 2025, the first day provisional measures were no longer in effect, until and through the day preceding the date of publication of the ITC's final injury determination in the Federal Register. Suspension of liquidation and the collection of cash deposits will resume on the date of publication of the ITC's final determination in the Federal Register. CVD Order As stated above, based on the ITC's final determination that an industry in the United States is materially injured within the meaning of section 705(b)(1)(A)(i) of the Act by reason of subsidized imports of hexamine from China, in accordance with section 705(c)(2) of the Act, Commerce is issuing this CVD order. Moreover, because the ITC determined that imports of hexamine from China are materially injuring a U.S. industry, unliquidated entries of subject merchandise from China entered, or withdrawn from warehouse, for consumption, are subject to the assessment of countervailing duties. See ITC Notification Letter.
