1. On 03/20/2026, Commerce published in the Federal Register its initiation of the antidumping duty investigation of large diameter graphite electrodes (large graphite electrodes) from the People's Republic of China (China) (91 FR 13581). The effective date of this initiation is 03/16/2026 (the applicable date stated in the FR notice). 2. The merchandise covered by this investigation includes all large diameter graphite electrodes of any length, whether or not finished, of a kind used in furnaces, with a nominal or actual diameter exceeding 425 millimeters (16.7 inches), and whether or not attached to a graphite pin joining system or any other type of joining system or hardware. The merchandise covered by this investigation also includes graphite pin joining systems (commonly referred to as pins or nipples) for large diameter graphite electrodes, of any length, and with a minimum diameter of 228.6 mm (9 inches) at its widest transverse cross-section, whether or not finished, of a kind used in furnaces, and whether or not the graphite pin joining system is attached to, sold with, or sold separately from, the large diameter graphite electrode. Unfinished large diameter graphite electrodes are graphitized electrodes that have not undergone final machining. For purposes of this investigation, the country of origin is determined by the country of graphitization. Excluded from the scope of this investigation are large diameter graphite electrodes that are subject to the existing antidumping duty order on Small Diameter Graphite Electrodes from the People's Republic of China. See Antidumping Duty Order: Small Diameter Graphite Electrodes from the People's Republic of China, 74 FR 8775 (February 26, 2009) (SDGE China AD Order) due to an affirmative determination of circumvention that imports of graphite electrodes from the People's Republic of China, produced and/or exported by Sinosteel Jilin Carbon Co., Ltd. and Jilin Carbon Import & Export Company (collectively, Jilin Carbon), with an actual or nominal diameter of 17 inches and otherwise meeting the description of the scope of the SDGE China AD Order constitute merchandise subject to the SDGE China AD Order. See Small Diameter Graphite Electrodes from the People's Republic of China: Affirmative Final Determination of Circumvention of the Antidumping Duty Order and Rescission of Later-Developed Merchandise Anticircumvention Inquiry, 78 FR 56864 (September 16, 2013). In the case of graphite electrodes entering the United States determined to be subject to the SDGE China AD Order, such order controls. In the case of graphite electrodes entering the United States meeting the scope definition of this investigation and not covered by the scope of the SDGE China AD Order, the scope of this investigation controls. Large diameter graphite electrodes and graphite pin joining systems for large diameter graphite electrodes that are covered by this investigation are currently classified under the Harmonized Tariff Schedule of the United States (HTSUS) statistical reporting number 8545.11.0020. Merchandise covered by this investigation may also enter under HTSUS statistical reporting numbers 3801.10.5090 or 3801.90.0050. The HTSUS numbers are provided for convenience and customs purposes, but the written description of the scope is dispositive. 3. This proceeding has been assigned case number A-570-220. 4.
