Shrimp exports to the US are enjoying a reduction in anti-dumping taxes.

The anti-dumping duties were placed on frozen warm water shrimp from Vietnam . The products were taxed from February 1, 2009 through January 31, 2010, reported the Vietnam Association of Seafood Exporters and Producers (VASEP).

The US Department of Commerce (DoC), after conducting their fifth administrative review, imposed new, reduced duties by between 1.28 percent and 2.56 percent to 1.36-1.67 percent on various exporters across the country.

For the past five years, the US has levied duties ranging from 2.5 to 25.76 percent on frozen shrimp imported from Vietnam .

Vietnam filed a case with the World Trade Organisation (WTO) in February 2010 to contest the tariffs. This marks the first time Vietnam has filed a complaint with the global trade body's dispute settlement system since it formally joined the WTO in January 2007.

Vietnam disagreed with the US 's method of calculating dumping by using periodic reviews, which is zeroing under US law. Vietnam argued that zeroing was inconsistent with WTO rules as well as with Vietnam 's protocol of accession to the trade organisation.

Last year, Vietnam exported 240,000 tonnes of shrimp worth of 2.08 billion USD to 92 markets, including the US. /.
