The U.S. Department of Commerce Announces End of Nearly Yearlong Investigation into Illegal Imports of Aluminum Extrusions

Per the U.S. Department of Commerce’s findings, China, Colombia, Ecuador, India, Indonesia, Italy, Malaysia, Mexico, South Korea, Taiwan, Thailand, Turkey, the United Arab Emirates and Vietnam sold dumped and subsidized aluminum extrusions into the U.S., violating international trade rules. As a result, antidumping duties have been imposed at rates ranging from 2.02% to 376.85%, along with countervailing duties ranging from 1.44% to 168.81%.

The investigation was prompted by a trade case filed in October 2023 by the U.S. Aluminum Extruders Coalition (USAEC), a coalition of 14 American extruders, and United Steelworkers union (USW), in which AEC officials said the domestic aluminum industry was in “a fight for [its] very existence.” The Aluminum Extruders Council alleged, “foreign producers of aluminum extrusions gained a significant and increasing share of the U.S. market at the direct expense of the U.S. industry.”  In 2022, AEC reported that the share of the U.S. market for aluminum extrusions decreased from 80% to 75% after tariffs were revoked. Officials say this translates to 300 million pounds of extrusions, equivalent to eight extrusion plants and 2,000 jobs.
