Scope of the measure

The product covered by this order is R-32 from China. For a complete description of the scope of the order, see Appendix I to this notice. Antidumping Duty Order On March 2, 2021, in accordance with sections 735(b)(i)(A)(i) and 735(d) of the Act, the ITC notified Commerce of its final determination that an industry in the United States is materially injured by reason of imports of R-32 from China. Therefore, in accordance with section 735(c)(2) of the Act, we are issuing this order. Because the ITC determined that imports of R-32 from China are materially injuring a U.S. industry, unliquidated entries of such merchandise from China which are entered, or withdrawn from warehouse, for consumption are subject to the assessment of antidumping duties.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 subject merchandise, for all relevant entries of R-32 from China. Antidumping duties will be assessed on unliquidated entries of R-32 from China entered, or withdrawn from warehouse, for consumption on or after August 27, 2020, the date of publication of the Preliminary Determination. See Difluoromethane (R-32) from the People's Republic of China: Preliminary Affirmative Determination of Sales at Less Than Fair Value and Postponement of Final Determination, 85 FR 52950 (August 27, 2020) (Preliminary Determination). Continuation of Suspension of Liquidation In accordance with section 736 of the Act, Commerce will instruct CBP to continue to suspend liquidation on all relevant entries of R-32 from China, which are entered, or withdrawn from warehouse, for consumption on or after the date of publication of the ITC's final determination in the Federal Register. These instructions suspending liquidation will remain in effect until further notice. Commerce will also instruct CBP to require cash deposits for estimated antidumping duties equal to the cash deposit rates for each producer and exporter combination listed below. Accordingly, effective on the date of publication in the Federal Register of the ITC's final determination, CBP will require, at the same time as importers would normally deposit estimated duties on the subject merchandise, a cash deposit equal to the rates listed below: See section 736(a)(3) of the Act.

China-Wide Entity 221.06 Provisional Measures 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 that Commerce may extend the four-month period to no more than six months at the request of exporters representing a significant proportion of exports of the subject merchandise. At the request of Taizhou Qingsong Refrigerant New Material Co., Ltd. and Zibo Feiyuan Chemical Co., Ltd., exporters that account for a significant proportion of R-32 from China, we extended the four-month period to six months. Commerce published its Preliminary Determination on August 27, 2020. See Preliminary Determination, 85 FR at 52952. The extended provisional measures period, beginning on the date of publication of the Preliminary Determination, ended on February 22, 2021. Therefore, in accordance with section 733(d) of the Act and our practice, we will instruct CBP to terminate the suspension of liquidation and to liquidate, without regard to antidumping duties, unliquidated entries of R-32 from China, entered, or withdrawn, from warehouse, for consumption on or after February 23, 2021, 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 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.
