US adds anti-dumping duties on chromium trioxide from India
The U.S. Department of Commerce has made a preliminary affirmative determination that chromium trioxide from India is being sold in the United States at less than fair value (LTFV), covering the period July 1, 2024 through June 30, 2025. This triggers provisional measures and sets the stage for a final anti-dumping duty determination. Importers of chromium trioxide and downstream manufacturers relying on Indian suppliers should prepare for potential duties and adjust sourcing or pricing strategies accordingly.

On May 22, 2026, the U.S. Department of Commerce issued a preliminary affirmative determination that chromium trioxide from India is being sold in the United States at less than fair value. The investigation covers the period of July 1, 2024 through June 30, 2025.
"The U.S. Department of Commerce (Commerce) preliminarily determines that chromium trioxide from India is being, or is likely to be, sold in the United States at less than fair value (LTFV)."
— Federal Register, May 22, 2026
This preliminary finding activates provisional measures under U.S. anti-dumping law and extends the timeline for a final determination. Chromium trioxide (HS code 2819.10) is a key chemical used in metal finishing, leather tanning, and specialized manufacturing. The preliminary ruling does not yet impose binding duties but signals a strong likelihood that anti-dumping duties will be assessed retroactively once Commerce issues its final determination.
Who is affected
U.S. importers of chromium trioxide from India—including chemical distributors, metal finishers, tanneries, and other industrial users—face immediate exposure. Any entry of the subject merchandise after the POI start date (July 1, 2024) may be subject to provisional cash deposits equivalent to the preliminary dumping margins once determined. Downstream manufacturers and end-users relying on Indian chromium trioxide will face cost pressures as suppliers pass through the provisional duties or pivot to alternative suppliers.
Interested parties have been invited to comment on the preliminary determination. Commerce will incorporate those comments into its final investigation, which typically concludes 120 days after the preliminary determination (unless postponed).
What this means for shippers
Importers must immediately review all outstanding chromium trioxide purchase orders and contracts from India. File comments with Commerce if you believe the preliminary finding is in error or if you can demonstrate non-dumped transactions. Prepare cash-flow models for provisional duty deposits on in-transit or pending shipments. Consider sourcing alternatives from countries not under anti-dumping investigation, or negotiate volume commitments with non-subject suppliers to lock in current pricing. Failure to adjust now risks margin compression if duties are backfilled to July 2024. /hs-codes/search
