UPDATE 1-U.S. sugar groups file trade complaint against Mexico

(Adds details of groups complaining, other background on imports)

WASHINGTON, March 28 (Reuters) - Several U.S. sugar cane and sugar beet groups on Friday asked the U.S. International Trade Commission to investigate what they called "dumped and subsidized" imports of certain sugar from Mexico, according to a filing with the commission.

"It is our intention to file countervailing duty and antidumping petitions against the Mexican sugar industry," said Phillip Hayes, a spokesman for the American Sugar Alliance, which represents U.S. producers.

The groups urging ITC action included the American Sugar Cane League, American Sugarbeet Growers Association, American Sugar Refining Inc, Florida Sugar Cane League, Hawaiian Commercial and Sugar Company, Rio Grande Valley Sugar Growers, Inc, Sugar Cane Growers Cooperative of Florida, and the United States Beet Sugar Association.

The U.S. sugar industry blames cheap imports from Mexico for driving down domestic prices.

The U.S. Department of Agriculture estimates sugar imports from Mexico in 2013/14 at 1.745 million short tons, but in a preliminary forecast in February said shipments would jump in the coming year to 2.26 million short tons.
