US antidumping review: Portuguese uncoated paper faces preliminary duties
The U.S. Department of Commerce has issued preliminary findings in its administrative review of antidumping duties on uncoated paper from Portugal for the period March 1, 2024–February 28, 2025. Commerce determined that subject producers and exporters made sales below normal value during the review period. The agency is inviting interested parties to comment before issuing final results. Exporters and importers of Portuguese uncoated paper should monitor this review closely, as the final determination will set new duty rates effective retroactively to the start of the review period.

The U.S. Department of Commerce has preliminarily determined that producers and exporters of uncoated paper from Portugal engaged in dumping—selling subject merchandise at less than normal value—during the March 1, 2024 through February 28, 2025 administrative review period, according to a notice published in the Federal Register on June 3, 2026.
The U.S. Department of Commerce (Commerce) preliminarily determines that producers/exporters subject to this review made sales of subject merchandise at less than normal value (NV) during the period of review (POR), March 1, 2024, through February 28, 2025.
This determination comes as part of Commerce's ongoing antidumping duty administrative review, a mandatory annual examination of whether foreign manufacturers continue to dump goods in the U.S. market. Administrative reviews are standard practice under U.S. antidumping law and allow Commerce to adjust duty rates based on the actual pricing behavior of subject exporters during the review period.
Uncoated paper (typically classified in HS Chapter 48) from Portugal has been subject to antidumping duties following an earlier investigation. This preliminary results notice marks a critical juncture: Commerce has found evidence of dumping, but the determination is not yet final. The agency is formally inviting interested parties—including importers, end-users, and the Portuguese exporters themselves—to submit factual comments and arguments before the final determination is issued.
The final determination will establish new antidumping duty rates applicable to Portuguese uncoated-paper shipments. These rates will be retroactive to the start of the review period (March 1, 2024) and will remain in effect until the next administrative review is initiated, typically one year later.
What this means for shippers
Importers of Portuguese uncoated paper must assume preliminary duties will become final and prepare landed-cost models reflecting increased tariff exposure. File comments with Commerce immediately if you have pricing, volume, or sourcing data that contradicts the preliminary finding—silence now forecloses your ability to challenge the final rate. Expect retroactive-duty liability backdated to March 1, 2024 once Commerce issues final results; verify your broker has reserved adequate cash-flow for duties on all shipments in the review period.
