**SUPPLEMENTARY INFORMATION:**
**Background**
On November 6, 2014, Commerce published the *Order* in the *Federal Register* . [^1] On September 2, 2025, Commerce published the notice of initiation of this second sunset review of the *Order,* pursuant to section 751(c) of the Tariff Act of 1930, as amended (the Act). [^2]
[^1]*See Steel Concrete Reinforcing Bar from Mexico: Antidumping Duty Order,* 79 FR 65925 (November 6, 2014) ( *Order* ).
[^2]*See Initiation of Five-Year (Sunset) Reviews,* 90 FR 42388 (September 2, 2025).
On September 16, 2025, Commerce received a timely and complete notice of intent to participate in the sunset review from a domestic interested party [^3] within the deadline specified in the 19 CFR 351.218(d)(1)(i). [^4] The domestic interested party claimed interested party status within the meaning of section 771(9)(F) of the Act as an association, a majority of whose members are composed of manufacturers, producers, or wholesalers in the United States of a domestic like product. [^5] On September 29, 2025, Commerce notified the U.S. International Trade Commission (ITC) that it had received a notice of intent to participate from the domestic interested party. [^6]
[^3] The domestic interested party is the Rebar Trade Action Coalition and its individual members, Nucor Corporation, Gerdau Ameristeel US Inc., Commercial Metals Company, Steel Dynamics, Inc., Byer Steel Group, Inc., and Optimus Steel, LLC.

[^6]*See* Commerce's Letter, “Sunset Reviews Initiated on September 2, 2025,” dated September 29, 2025.
On October 2, 2025, pursuant to 19 CFR 351.218(d)(3)(i), the domestic interested party filed a timely and adequate substantive response. [^7] On October 12, 2025, Commerce received a substantive response from Grupo Simec, [^8] a respondent interested party. [^9] Commerce determined that Grupo Simec's substantive response “did not, as required by 19 CFR 351.218(e)(1)(ii)(A), contain an adequate response demonstrating that its volume and value of exports of subject merchandise to the United States accounted, on average, for more than 50 percent, on a volume basis, of the total exports of subject merchandise to the United States over the five calendar years preceding the notice of initiation of this review.” [^10] Therefore, on December 8, 2025, Commerce notified the ITC that it did not receive an adequate substantive response from any respondent interested parties. [^11] As a result, pursuant to section 751(c)(3)(B) of the Act and 19 CFR 351.218(e)(1)(ii)(C)(2), Commerce is conducting an expedited (120-day) sunset review of the *Order.*

Due to the lapse in appropriations and Federal Government shutdown, on November 14, 2025, Commerce tolled all deadlines in administrative proceedings by 47 days. [^12] Additionally, due to a backlog of documents that were electronically filed via Enforcement and Compliance's Antidumping and Countervailing Duty Centralized Electronic Service System (ACCESS) during the Federal Government shutdown, on November 24, 2025, Commerce tolled all deadlines in administrative proceedings by an additional 21 days. [^13] Accordingly, the deadline for these final results is now March 9, 2026.
