Imperial Sugar Company and AmCane Sugar, two U.S. refiners that rely on imported raw sugar, have taken the second step in their fight to kill the settlements reached in December to suspend the antidumping and countervailing duty cases against Mexican sugar imports, Inside U.S. Trade reported today.

Both refiners say they support the notion of settling the trade dispute in principle, but they want an agreement on better terms, Inside U.S. Trade said.

On Wednesday the International Trade Commission announced the launch of the review of the agreement that the two companies had requested.

Inside U.S. Trade said sources had told the publication that “Specifically, the two U.S. refiners reject the spread between the floor price of raw sugar in the agreements and that for refined sugar as too small to allow them to profitably refine imported raw sugar and package it for consumer end use ... The suspension agreements increase the price of Mexican raw sugar, which will also affect the price of other imports because Mexico is such a large shipper.”

The suspension agreements allow Mexico to ship 53 percent of its total exports as refined sugar to the United States.
