The combination of new anti-dumping fees and the National Oceanic and Atmospheric Administration’s (NOAA) seafood import monitoring program (SIMP) rules will slow the amount of shrimp Vietnam sends to the US, the Vietnam Association of Seafood Exporters and Producers (VASEP) is warning.

Although they reached more than $1 billion during the first four months of 2018, up 13.8% over the same period in 2017, Vietnam shrimp exports were 0.4% lower in April 2018 than the same month in 2017, Vietnam Economic News reports.

The US Department of Commerce, in March, announced the preliminary results of its latest review of dumping practices related to Vietnamese shrimp imported by the US between February 1, 2016 and January 31, 2017, determining that it would charge a fee of 25.39%, much higher than previous fees.

Then, in April, NOAA gave notice that it was adding shrimp to the types of seafood required to comply with its SIMP rules, paperwork requirements aimed at reducing the amount of illegally and underreported seafood imported by the US.

VASEP has suggested that Vietnam’s Ministry of Agriculture and Rural Development adopt its solutions for sustainable shrimp production and exports, the news service notes. The group also is urging the government to continue engaging in high-level diplomacy to convince the US to remove trade barriers.
