Mexico's President, Andrés Manuel López Obrador, has issued a decree to modify the temporary tariffs on white corn. The decree aims to stabilize grain prices and boost production and marketing. It eliminates the exemption of import tariffs on white flour corn, which did not significantly reduce market prices. The decree also sets a 50% import and export tariff quota per kilogram of white corn until December 31, 2023. The measures are designed to protect and strengthen national agriculture, particularly the white corn sector.
