On 24 April 2006, Thailand requested consultations with the United States concerning anti-dumping measures on imports of frozen warmwater shrimp. Thailand requests consultations on the United States’ application in the Preliminary, Final and Amended Final Determinations of the practice known as “zeroing” negative dumping margins, the effect of which was to artificially create margins of dumping, and the consequent imposition of definitive anti-dumping measures on imports of certain frozen warmwater shrimp from Thailand.
