The merchandise covered by the Orders includes all grades of aqueous acidic (non-neutralized) concentrations of HEDP, also referred to as hydroxyethylidenendiphosphonic acid, hydroxyethanediphosphonic acid, acetodiphosphonic acid, and etidronic acid. The Chemical Abstract Service (CAS) registry number for HEDP is 2809-21-4. The merchandise subject to the Orders is currently classified in the Harmonized Tariff Schedule of the United States (HTSUS) at subheading 2931.90.9043. It may also enter under HTSUS subheadings 2811.19.6090, 2931.90.9041, 2931.90.9051, 2811.19.6190, and 2931.39.0018. While HTSUS subheadings and the CAS registry number are provided for convenience and customs purposes only, the written description of the scope of the Orders is dispositive. On September 24, 2020, U.S. Customs and Border Protection (CBP) notified Commerce of additional HTSUS subheadings under which subject merchandise can be entered. Accordingly, the scope of the Orders now reflects those additional HTSUS subheadings. See AD Sunset Final, 87 FR at 42706; and CVD Sunset Final, 87 FR at 42707. Continuation of the Orders As a result of the determinations by Commerce and the ITC that revocation of the Orders would likely lead to a continuation or a recurrence of dumping and countervailable subsidies, as well as material injury to an industry in the United States, pursuant to section 751(d)(2) of the Act, Commerce hereby orders the continuation of the Orders. CBP will continue to collect AD and CVD cash deposits at the rates in effect at the time of entry for all imports of subject merchandise. The effective date of the continuation of the Orders will be the date of publication in the Federal Register of this notice of continuation. Pursuant to section 751(c)(2) of the Act, Commerce intends to initiate the next five-year reviews of the Orders not later than 30 days prior to the fifth anniversary of the effective date of continuation. Administrative Protective Order This notice serves as the only reminder to parties subject to an administrative protective order (APO) of their responsibility concerning the disposition of proprietary information disclosed under APO in accordance with 19 CFR 351.305(a)(3), which continues to govern business proprietary information in this segment of the proceeding. Timely notification of return/destruction of APO materials or conversion to judicial protective order is hereby requested. Failure to comply with the regulations and terms of the APO is a sanctionable violation. Notification to Interested Parties These five-year sunset reviews and this notice are in accordance with section 751(c) of the Act and published in accordance with section 777(i)(1) of the Act and 19 CFR 351.218(f)(4).
