## Background

                    On March 19, 2008, Commerce published in the                     **Federal Register**                     the AD order on SHMP from China.[1]                                          On February 1, 2024, the ITC instituted,[2]                                          and Commerce initiated,[3]                                          the third sunset review of the                     *Order,*                     pursuant to section 751(c) of the Tariff Act of 1930, as amended (the Act). As a result of its review, Commerce determined that revocation of the                     *Order*                     would likely lead to the continuation or recurrence of dumping, and therefore, notified the ITC of the magnitude of the margins of dumping rates likely to prevail should the                     *Order*                     be revoked.[4] 

                    On October 2, 2024, the ITC published its determination, pursuant to sections 751(c) and 752(a) of the Act, that revocation of the                     *Order*                     would likely lead to continuation or recurrence of material injury to an industry in the United States within a reasonably foreseeable time.[5] 

## Scope of the Order

                    The merchandise subject to the                     *Order*                     is sodium hexametaphosphate (SHMP). SHMP is a water-soluble polyphosphate glass that consists of a distribution of polyphosphate chain lengths. It is a collection of sodium polyphosphate polymers built on repeating NaPO3 units. SHMP has a P2O5 content from 60 to 71 percent. Alternate names for SHMP include the following: Calgon; Calgon S; Glassy Sodium Phosphate; Sodium Polyphosphate, Glassy; Metaphosphoric Acid; Sodium Salt; Sodium Acid Metaphosphate; Graham's Salt; Sodium Hex; Polyphosphoric Acid, Sodium Salt; Glass H; Hexaphos; Sodaphos; Vitrafos; and BAC-N-FOS. SHMP is typically sold as a white powder or granule (crushed) and may also be sold in the form of sheets (glass) or as a liquid solution. It is imported under heading 2835.39.5000, HTSUS. It may also be imported as a blend or mixture under heading 3824.90.3900, HTSUS. The American Chemical Society, Chemical Abstract Service (CAS) has assigned the name “Polyphosphoric Acid, Sodium Salt” to SHMP. The CAS registry number is 68915-31-1. However, SHMP is commonly identified by CAS No. 10124-56-8 in the market. For purposes of the                     *Order,*                     the narrative description is dispositive, not the tariff heading, CAS registry number or CAS name.                

                    The product covered by the                     *Order*                     includes SHMP in all grades, whether food grade or technical grade. The product covered by the                     *Order*                     includes SHMP without regard to chain length                     *i.e.,*                     whether regular or long chain. The product covered by the                     *Order*                     includes SHMP without regard to physical form, whether glass, sheet, crushed, granule, powder, fines, or other form, and whether or not in solution.                

                    However, the product covered by the                     *Order*                     does not include SHMP when imported in a blend with other materials in which the SHMP accounts for less than 50 percent by volume of the finished product.                

## Continuation of the Order

                    As a result of the determinations by Commerce and the ITC that revocation of the                     *Order*                     would likely lead to continuation or recurrence of dumping and 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                     *Order.*                     U.S. Customs and Border Protection will continue to collect AD 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                     *Order*                     is October 2, 2024. Pursuant to section 751(c)(2) of the Act and 19 CFR 351.218(c)(2), Commerce intends to initiate the next five-year review of the                     *Order*                     not later than 30 days prior to the fifth anniversary of the date of the last determination by the Commission.                

## Administrative Protective Order (APO)

This notice also serves as the only reminder to parties subject to an APO of their responsibility concerning the return or destruction 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 proceedings. Timely written notification of the return or destruction of APO materials, or conversion to judicial protective order, is hereby requested. Failure to comply with the regulations and terms of an APO is a violation which is subject to sanction.

## Notification to Interested Parties
