US finalizes antidumping duties on Vietnamese shrimp

The US Department of Commerce finalized antidumping duty margins ranging from 6.36% to 10.71% for certain Vietnamese exporters of frozen warmwater shrimp, with the applicable rate varying by company, according to final results published in the Federal Register and applicable Nov. 6.

Commerce determined that Vietnamese producers and exporters subject to the review sold certain frozen warmwater shrimp in the US at prices below normal value during the review period from Feb. 1, 2024, through Jan. 31, 2025.

Commerce calculated a final weighted-average dumping margin of 10.71% for the FIMEX Group, including Sao Ta Foods Joint Stock Company, slightly below the preliminary rate of 10.76%.

The final margin for Soc Trang Seafood Joint Stock Company, or STAPIMEX, increased to 6.36% from a preliminary 6.30%. Another 27 Vietnamese exporters eligible for a separate rate received a final margin of 7.59%, compared with 7.56% in the preliminary results.

Commerce also determined that another 131 Vietnamese producers and exporters were part of the Vietnam-wide entity and subject to the existing 25.76% Vietnam-wide rate.

Commerce will issue instructions to US Customs and Border Protection to assess antidumping duties on entries covered by the review. The final results also establish cash-deposit requirements for future entries, with applicable rates varying by exporter.

The changes in cash-deposit requirements vary significantly among the reviewed exporters. STAPIMEX's cash-deposit rate will fall to 6.36% from 25.76%, while FIMEX's rate will increase to 10.71% from 4.28%, according to the Southern Shrimp Alliance. The cash-deposit rate for the other 27 separate-rate exporters will increase to 7.59% from 4.28%.

The 10.71% margin calculated for FIMEX is the highest calculated dumping margin for an independent Vietnamese shrimp exporter since the antidumping duty order was implemented in February 2005, according to the Southern Shrimp Alliance. The rate surpassed the previous high of 9.75% calculated for STAPIMEX during the eighth administrative review.

Vietnamese exports to US down

The Southern Shrimp Alliance estimated that US importers of STAPIMEX shrimp could owe more than $9.2 million in additional antidumping duties on entries made during the review period, while importers of FIMEX shrimp could owe more than $6.3 million. The organization said the estimates were based on publicly reported shipment values submitted during the administrative review.

The final results come as Vietnamese shrimp shipments to the US have declined despite growth in overall US shrimp imports.

US imports under the broader shrimps and prawns category totaled 71,605.6 metric tons in September, up 12.6% from 63,565.4 mt in September 2025, according to USDA Foreign Agricultural Service Global Agricultural Trade System data. The trade category is broader than the frozen warmwater shrimp covered by Commerce's antidumping order.

Vietnam supplied 5,109.2 mt during September, down 8.1% from 5,561.3 mt a year earlier and accounting for about 7.1% of total US shrimp and prawn imports during the month.

By comparison, India supplied 27,205.7 mt, up 3.2% year over year, while Ecuadorian shipments increased 17.5% to 22,219.7 mt. Indonesian shipments increased 50.1% to 11,151.9 mt.

Vietnam's weaker shipments to the US contrast with growth in the country's broader shrimp sector. According to the S&P Global Energy Global Aquaculture Short-Term Outlook, Vietnamese shrimp production is expected to increase 6.5% in 2026 to 1.01 million mt. Vietnam's June shrimp exports totaled 44,553 mt, up 15.6% year over year, with first-half trade also 15.6% above the year-earlier period. China accounted for most of the export growth, with shipments nearly doubling year over year.

The revised margins could affect the relative cost of Vietnamese shrimp in the US, although the impact will vary by exporter and applicable cash-deposit rate. September trade data showed Vietnamese shipments declining even as overall US shrimp and prawn imports increased.
