Brazil dissolving pulp faces US dumping duty—preliminary ruling
The U.S. Department of Commerce has issued a preliminary affirmative determination that high-purity dissolving pulp from Brazil is being sold in the United States at less than fair value (LTFV), triggering anti-dumping investigation procedures. The investigation period runs July 1, 2024, through June 30, 2025. Importers and interested parties can submit comments on the preliminary ruling; a final determination is expected later in the anti-dumping process.

On May 27, 2026, the U.S. Department of Commerce issued a preliminary affirmative determination that high-purity dissolving pulp from Brazil is being, or is likely to be, sold in the United States at less than fair value. The investigation covers the period of July 1, 2024, through June 30, 2025.
Who This Affects
This preliminary determination subjects imports of dissolving pulp (HS 47.03 and related chapters) from Brazil to anti-dumping duty scrutiny. Importers of Brazilian dissolving pulp, domestic producers, exporters, and all interested parties are now part of an active anti-dumping case.
The U.S. Department of Commerce preliminarily determines that high purity dissolving pulp from Brazil is being, or is likely to be, sold in the United States at less than fair value.
Dissolving pulp is used in the manufacture of viscose fibers, cellulose acetate, and other specialty chemical products. A preliminary affirmative LTFV ruling signals that Commerce has found sufficient evidence—at this stage—that the Brazilian exporters are pricing below their home-market or constructed values.
What Happens Next
This preliminary determination triggers the standard anti-dumping process. Interested parties—including importers, domestic competitors, and the exporting company or government—are invited to submit comments and additional information for Commerce's consideration in its final determination. The case will proceed through the International Trade Commission's (ITC) injury investigation in parallel. Commerce will issue a final determination later in the process.
Pendency of the preliminary ruling means that provisional measures (such as preliminary duties or bonds) may be in effect on entries made after the determination. Importers should monitor the Federal Register for final duty rates and the effective date of any definitive anti-dumping duties.
What this means for shippers
Importers of Brazilian dissolving pulp must immediately review their sourcing, landed-cost models, and supply-chain strategy. Preliminary duties could be assessed retroactively or imposed on future shipments. Update your tariff classifications and duty estimates now, and track the final determination timeline to plan inventory and pricing adjustments before duties become definitive. Check /hs-codes/search to confirm your dissolving pulp HS code and prepare for duty recalculation.
