One of Brazil's largest orange juice processors continues to dump product into U.S. markets, even after the Department of Commerce was notified of the activity.

That's the assertion Lakeland-based Florida Citrus Mutual made in a supplementary document filed with the department.

Mike Sparks, Mutual executive vice president and chief executive officer, says the group based their complaint on recent monthly trade data that showed that Sao-Paulo-based Citrovita dumped orange juice into the U.S. market as late as May, according to a news release.

“A comparison of official import statistics to manifest data provides clear evidence that Citrovita has been dumping orange juice in the United States,” Sparks said in the release.

In April, Mutual filed its original anti-dumping petition, claiming Citrovita sold orange juice into the U.S. market below the cost of production.

In the petition, the Lakeland-based trade group wanted Citrovita added to the list of four processors on the current anti-dumping order. They are Citrosuco, Cutrale, a Louis Dreyfus affiliate and Montecitrus.

Those four are subject to Department of Commerce pricing scruitiny. In addition, they have to pay a deposit that is refunded only if they can show they didn't dump product.

The antidumping order is estimated to have increased the on-tree value of Florida orange crops by 4 percent to 6 percent, or $85 million to $125 million, over the 2005-06 and 2006-07 seasons, according to Citrus Mutual.
