Updated on Oct. 5, 2026 in International Trade
The U.S. Department of Commerce has amended its final administrative review results concerning light-walled rectangular pipe and tube from Mexico. The move follows a court mandate to adjust dumping margins to align with the results of a second remand.
Why it matters
The amendment ensures federal regulatory actions remain in harmony with judicial rulings. It reflects the ongoing oversight of trade practices between the United States and international partners regarding steel products.
The dumping margin for Maquilacero and Tecnicas de Fluidos increased to 10.67 percent, while margins for non-selected companies rose to 6.06 percent. These figures cover goods imported during the administrative review period ending in 2021.
