The Mexico government has lost an appeal at the World Trade Organisation against a disputes panel ruling that it should review its 10.18% anti-dumping duties levied on American rice because it had used faulty procedures assessing whether the US had been dumping long grain rice.

Mexico claimed the original panel “erred” in its findings about the investigation staged by its economics ministry. However, the appellate body rejected 16 of the 17 claims made by Mexico and recommended it bring the tariffs in line with WTO anti-dumping, and subsidies & countervailing measures agreements, effectively ordering the duties be lowered, at the very least.
