In its final results published August 12, 2026, the U.S. Department of Commerce raised the antidumping duty on one Vietnamese pangasius exporter, NTSF Seafoods, by more than 440% compared to the preliminary rate issued earlier the same year — from $0.07 per kilogram to $0.38 per kilogram. Another exporter, Bien Dong Seafood, saw its rate jump from $0.29 to $1.00 per kilogram, a roughly 245% increase. For buyers who treat antidumping duty as a fixed cost baked into last year's landed price, this review cycle is a reminder that it isn't fixed at all.
Pangasius: the 21st review reset the numbers
This was the 21st administrative review of the antidumping order on frozen pangasius and basa fillets from Vietnam, covering the period August 1, 2023 to July 31, 2024 — reviews run on a roughly one-year lag, so the rate finalized in August 2026 reflects shipments already sold. Beyond NTSF and Bien Dong, Can Tho Seafood Import-Export (Caseamex) and Nam Viet (Navico) — both named in Commerce's Federal Register notice and covered in trade press releases at the time — moved from a $0/kg rate in the prior review to $0.84/kg in this one. Companies outside the named respondent list fall under the Vietnam-wide rate, which stands at $2.39/kg — effectively a prohibitive rate for any exporter without an individually calculated or separate rate on file.
The pattern buyers should take from this: a company's rate from the last review is not a reliable predictor of its rate in the next one. Preliminary and final results in the same cycle have differed by 3–5x. Any landed-cost model that locks in an exporter's duty rate for planning purposes beyond the current review period is building in real risk.
Shrimp faces two separate duty tracks
Shrimp sits under both an antidumping order and a countervailing duty order, and the two move on different schedules. On the antidumping side, Commerce's final results for the 2023–2024 period of review were published February 23, 2026, covering sales from February 1, 2023 through January 31, 2024. Twenty-four exporters qualified for individually calculated separate rates in that review; one respondent, Trang Khanh Seafood, was rescinded from the review entirely. Preliminary results for the following period (2024–2025) were already out by May 2026, so a further final adjustment is due before this order's next full cycle closes.
On the countervailing duty side, Commerce's final affirmative determination — issued October 28, 2024 and still the controlling CVD rate as of this writing — set Soc Trang Seafood (STAPIMEX), the sole mandatory respondent, at 2.84%. Companies that declined to cooperate with the investigation, such as Thong Thuan, were assigned 221.82% under adverse facts available — a rate that functions as a de facto export block. For context, Commerce's 2.84% rate for cooperating Vietnamese shrimp exporters compares to 3.78% for Ecuador and 5.63% for India in the same period, which is a data point worth keeping in mind before assuming Vietnam is automatically the higher-duty origin on shrimp.
Why the exporter's name matters more than the country of origin
The consistent thread across both products is that duty exposure is decided at the company level, not the country level. A pangasius buyer working with Caseamex or Navico is now looking at $0.84/kg they weren't paying under the prior review; a buyer working with a company that never registered for a separate rate is exposed to the $2.39/kg Vietnam-wide rate regardless of that company's actual pricing behavior. The same logic applies on shrimp — a cooperating, individually-rated exporter and a non-cooperating one sit on opposite sides of a 200-point percentage gap.
What this means for buyers sourcing now
Before finalizing a contract, ask your supplier directly which administrative review rate applies to their company by name, and get the citation — the Federal Register notice number, not a verbal assurance. If a factory can't produce that, treat it as a flag, not a formality. For pangasius specifically, confirm whether the exporter has an individually calculated rate from the 21st review or falls under the Vietnam-wide rate; for shrimp, confirm both the AD separate-rate status and the CVD rate, since they're determined independently and a company can be favorable on one and not the other. This is exactly the kind of verification I do before recommending a factory to a buyer — the duty rate is public record, but matching the right company to the right rate takes someone checking it against the current review, not last year's.
