The department said it received requests from the Ad Hoc Shrimp Trade Action Committee, the American Shrimp Processors Association (ASPA), the Louisiana Shrimp Association (LSA), and certain individual companies for new administrative reviews of the antidumping duty orders on shrimp from producers in the three countries.

In all, more than 100 companies will be covered by the review, which covers the one-year period from Feb. 1, 2009 through Jan. 31, according to the announcement Wednesday in the Federal Register.

A separate announcement on Friday in the Federal Register listed more than 100 Chinese and Vietnamese companies.
