Scope of the measure

The product covered by this order is MDI from China. For a complete description of the scope of the order, see the appendix to this notice. Amended Final Determination Commerce has reviewed the record and agrees that the ministerial errors alleged by Wanhua and the petitioner constitute ministerial errors within the meaning of section 705(e) of the Act and 19 CFR 351.224(f). Specifically, Commerce found that it made an error in calculating the surrogate values for both natural gas and nitrogen, and miscalculated the surrogate selling, general, and administrative expenses ratio and the surrogate profit ratio. Additionally, Commerce erred in calculating normal value. Pursuant to 19 CFR 351.224(e), Commerce is amending the Final Determination to reflect the correction of the ministerial errors as described in the Ministerial Error Memorandum. See Memorandum, ``Analysis of Ministerial Error Allegations,'' dated concurrently with, and hereby adopted by, this notice (Ministerial Error Memorandum). Antidumping Duty Order On May 29, 2026, in accordance with section 735(d) of the Act, the ITC published in the Federal Register its final determination in its investigation, in which it found that an industry in the United States is materially injured by reason of imports of MDI from China. Therefore, in accordance with sections 735(c)(2) and 736 of the Act, Commerce is issuing this antidumping duty order. Because the ITC determined that imports of MDI from China are materially injuring a U.S. industry, unliquidated entries of such merchandise from China, entered or withdrawn from warehouse for consumption, are subject to the assessment of antidumping duties. See ITC Final Determination. 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 MDI from China. Antidumping duties will be assessed on unliquidated entries of MDI entered, or withdrawn from warehouse, for consumption on or after September 16, 2025, the date of publication of the Preliminary Determination, but will not include entries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 under section 735(d) of the Act, as further described in the ``Provisional Measures'' section of this notice. See Methylene Diphenyl Diisocyanate from the People's Republic of China: Preliminary Affirmative Determination of Sales at Less-Than-Fair-Value, Postponement of Final Determination, and Extension of Provisional Measures, 90 FR 44629 (September 16, 2025) (Preliminary Determination). Continuation of Suspension of Liquidation and Cash Deposit Requirements Except as noted in the ``Provisional Measures'' section of this notice, in accordance with section 735(c)(1)(B) of the Act, Commerce intends to instruct CBP to continue to suspend liquidation on all relevant entries of MDI from China. 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 margins indicated in the table below. 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 tables below. The China-wide entity rate applies to all producer/exporter combinations not specifically listed. Estimated Weighted-Average Dumping Margins The estimated weighted-average dumping margins are as follows: Weighted-average Producer Exporter dumping margin (percent) Covestro Polymers (China) Co., Covestro Polymers 87.25 Ltd. (China) Co., Ltd. Wanhua Chemical Group Co., Ltd.. Shandong Mingko 87.25 Co., Ltd. China-Wide Entity 161.61 Provisional Measures Section 773(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. At the request of exporters that account for a significant proportion of MDI from China, Commerce extended the four-month period to six months in this investigation. Id. The extended provisional measures period, beginning on the date of publication of the Preliminary Determination on September 16, 2025, ended on March 14, 2026. Therefore, in accordance with section 733(d) of the Act and our practice, Commerce will instruct CBP to terminate suspension of liquidation and to liquidate, without regard to antidumping duties, unliquidated entries of MDI from China entered, or withdrawn from warehouse, for consumption on or after March 14, 2026, 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.
