 2025. No appeal was filed against the DOC’s final determination and, accordingly, the DOC instructed the customs authorities to liquidate the corresponding refunds at the assessment rate of Tenaris’s imports from Argentina for the first review period, with such instructions becoming effective on August 4, 2025. Although no refunds had been liquidated by the customs authorities as of September 30, 2025, the resulting gain (including interest) was recognized in these Consolidated Condensed Interim Financial Statements.

On September 5, 2025, the DOC issued its final determination for imports from Mexico that occurred during the first review period, announcing a final rate of 26.10%. Both petitioners and Tenaris have indicated that they intend to appeal this determination. As a result, the DOC has not instructed the customs authorities to liquidate these entries and will not do so while the appeals are ongoing. On October 8, 2025, Tenaris began the process for appealing the DOC determination.

As a result of these periodic reviews, the deposit rates on future imports can change, and the antidumping duty deposits paid on imports during the relevant review period may be either returned to Tenaris (in whole or in part) or increased.
