The US Department of Commerce (USDOC) issued an amended final determination and anti-dumping (AD) duty order for corrosion-resistant steel products (CORE) from Mexico covering the investigation period from July 1, 2023, to June 30, 2024.

The revision complies with an October 19, 2026, final judgment by the US Court of International Trade (CIT) sustaining Commerce's first remand redetermination.

Under the amended determination, the weighted-average dumping margin for producer Galvasid S.A. De C.V. decreased from 24.09% to 14.54%. In addition, the dumping rate assigned to all other Mexican producers and exporters was reduced from 17.42% to 14.29%.
