1. On 05/24/2023, Commerce published in the Federal Register its initiation of the antidumping duty investigation of brass rod from the Republic of Korea (88 FR 33575). The effective date of this initiation is 05/17/2023 (the applicable date stated in the FR notice). 2. The products covered by this investigation are brass rod and bar (brass rod), which is defined as leaded, low-lead, and no-lead solid brass made from alloys such as, but not limited to the following alloys classified under the Unified Numbering System (UNS) as C27450, C27451, C27460, C34500, C35000, C35300, C35330, C36000, C36300, C37000, C37700, C48500, C67300, C67600, and C69300, and their international equivalents. The brass rod subject to this investigation has an actual cross-section or outside diameter greater than 0.25 inches but less than or equal to 12 inches. Brass rod cross-sections may be round, hexagonal, square, or octagonal shapes as well as special profiles (e.g., angles, shapes). Standard leaded brass rod covered by the scope contains, by weight, 57.0 - 65.0 percent copper; 0.5 - 3.0 percent lead; no more than 1.3 percent iron; and at least 15 percent zinc. No-lead or low-lead brass rod covered by the scope contains by weight 59.0 - 76.0 percent copper; 0 - 1.5 percent lead; no more than 0.35 percent iron; and at least 15 percent zinc. Brass rod may also include other chemical elements (e.g., nickel, phosphorous, silicon, tin, etc.). Brass rod may be in straight lengths or coils. Brass rod covered by this investigation may be finished or unfinished, and may or may not be heated, extruded, pickled, or cold-drawn. Brass rod may be produced in accordance with ASTM B16, ASTM B124, ASTM B981, ASTM B371, ASTM B453, ASTM B21, ASTM B138, and ASTM B927, but such conformity to an ASTM standard is not required for the merchandise to be included within the scope. Excluded from the scope of this investigation is brass ingot, which is a casting of unwrought metal unsuitable for conversion into brass rod without remelting, that contains, by weight, at least 57.0 percent copper and 15.0 percent zinc. The merchandise covered by this investigation is currently classifiable under subheadings 7407.21.9000, 7407.21.7000, and 7407.21.1500 of the Harmonized Tariff Schedule of the United States (HTSUS). Products subject to the scope may also enter under HTSUS subheadings 7403.21.0000, 7407.21.3000, and 7407.21.5000. The HTSUS subheadings and UNS alloy designations are provided for convenience and customs purposes. The written description of the scope of the investigation is dispositive. 3. This proceeding has been assigned case number A-580-916. 4.
