The International Association of Machinists and Aerospace Workers (IAM Union) participated in a recent briefing with labor experts and members of Congress to highlight labor priorities for the upcoming review of the U.S.-Mexico-Canada Agreement (USMCA). The event aimed to inform Congressional staff and leaders about ongoing concerns regarding wage disparities, enforcement challenges, and foreign exploitation that continue to affect American jobs.
Key topics discussed included proposals to strengthen Rules of Origin, which are intended to prevent companies from relocating production outside the United States. Participants also called for closing loopholes that allow goods assembled or transshipped through Mexico—particularly those originating from China—to enter the U.S. market without tariffs. Expanding enforcement tools such as the Rapid Response Mechanism was another priority raised, along with efforts to reduce wage gaps that can lead to job losses in key industries like aerospace, automotive, steel, and aluminum.
Peter Greenberg, IAM Union International Affairs Director, emphasized the importance of addressing vulnerabilities in the aerospace sector. “One of our great fears has been an interruption of the aerospace supply chain, particularly because it is very closely tied between the U.S. and Canada,” said Greenberg.
He also warned about potential exploitation by China: “China is using Mexico as a transshipment location,” Greenberg continued. “It allows goods to be repackaged and essentially enter the United States tariff-free.” He added that Mexico could serve as a final assembly point for Chinese aerospace products, posing risks to jobs at major manufacturers such as Boeing and Airbus, as well as U.S. jet engine makers. Greenberg referenced China’s expansion into commercial aviation with its COMAC C919 aircraft and noted that initiatives like Belt and Road financing are increasing competition for North American producers.
Other speakers at the briefing included U.S. Rep. Linda Sánchez (D-Calif.), Ranking Member of the House Ways and Means Trade Subcommittee; Riley Ohlson, Legislative Representative for AFL-CIO; Roy Houseman, Legislative Director for United Steelworkers; and Christopher Zatratz, Legislative Representative for United Auto Workers.
