Mexico targets Japanese plate in new dumping case
Written by Laura Miller
Mexico has formally opened an anti-dumping investigation into imports of cut-to-length steel plate from Japan.
Mexico’s Ministry of Economy launched the trade case after a complaint by Grupo Acerero (GASA).
GASA, a San Luis Potosi-based steel producer, alleges price discrimination and injury to the Mexican industry, according to the announcement in Mexico’s Official Gazette of the Federation.
The case targets hot-rolled, uncoated, non-coil carbon steel plate in sheet form, at least 4.75 mm thick and 600 mm wide.
The investigation period covers the 2025 calendar year.
One Mexican trader SMU spoke to said the dumping allegations make sense. “Due to the free trade agreement, there are no tariffs against Japan,” he explained. “Japan has become the cheapest alternative to Mexico in all products.”
The trader noted that most Japanese products face tariffs or anti-dumping duties in the US, “so Japan has been dumping their excess production in Mexico.”
“I think we will see more cases of dumping against Japan,” the trader said.
