**AGENCY:**
Enforcement and Compliance, International Trade Administration, Department of Commerce.
**SUMMARY:**
On August 1, 2025, the U.S. Department of Commerce (Commerce) initiated the first sunset review of the antidumping duty (AD) order on polyethylene terephthalate (PET) sheet from the Republic of Korea (Korea). Because no domestic party responded to the sunset review notice of initiation by the applicable deadline, consistent with section 751(c)(3)(A) of the Tarriff Act of 1930, as amended (the Act), Commerce is revoking the AD order on polyethylene terephthalate sheet from Korea.
**DATES:**
Applicable January 12, 2026.

**SUPPLEMENTARY INFORMATION:**
**Background**
On September 10, 2020, Commerce published the *Order* on PET sheet from Korea. [^1] On August 1, 2025 Commerce initiated the first sunset review of the *Order* pursuant to section 751(c) of the Act. [^2]
[^1]*See Polyethylene Terephthalate Sheet from the Republic of Korea and the Sultanate of Oman: Antidumping Duty Orders,* 85 FR 55824, (September 10, 2020) ( *Order* ).
[^2]*See Initiation of Five-Year (Sunset) Reviews,* 90 FR 36139, dated August 1, 2025.
We did not receive a timely notice to participate in this sunset review from any domestic interested party, pursuant to 19 CFR 351.218(d)(1)(i). As a result, consistent with 19 CFR 351.218(d)(1)(iii)(B)(1), because Commerce “did not receive a Notice of Intent to Participate from a domestic party in the sunset review of the { *Order* },” Commerce notified the U.S. International Trade Commission (ITC) in writing pursuant to 19 CFR 315.218(d)(1)(iii)(B)(2). [^3] Further, we did not receive a timely substantive response to the notice of initiation of this sunset review from any domestic party, and, pursuant to section 751(c)(3)(A) of the Act and 19 CFR 351.218(e)(1)(i)(C)(3), notified the ITC of our intent to revoke this *Order* “not later than 90 days after the date of publication of the *Federal Register* notice of initiation.” [^4]

[^4]*See* Commerce's Letter, “Sunset Review Initiated on August 1, 2025,” dated September 11, 2025.
Due to the lapse in appropriations and Federal Government shutdown, on November 14, 2025, Commerce tolled all deadlines in administrative proceedings by 47 days. [^5] 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. [^6] Accordingly, the deadline for these final results is now January 6, 2026.
[^5]*See* Memorandum, “Deadlines Affected by the Shutdown of the Federal Government,” dated November 14, 2025.
[^6]*See* Memorandum, “Tolling of all Case Deadlines,” dated November 24, 2025.

Pursuant to section 751(c)(3)(A) of the Act, “{i}f no interested party responds to the notice of initiation . . . {Commerce} shall issue a final determination, within 90 days after the initiation of a review, revoking the order.” Because no domestic interested parties responded to the notice of initiation in these segments of the proceeding, Commerce is revoking the *Order.*
