Why It Matters

The United States-Mexico-Canada Agreement (USMCA), which entered into force in 2020 and replaced the North American Free Trade Agreement (NAFTA), included stronger labor provisions by placing labor obligations in the agreement's core text and subjecting them to enforceable dispute settlement mechanisms.

The agreement's labor rules have become a central part of U.S. trade enforcement, particularly in Mexico, where the United States has repeatedly invoked the Rapid Response Labor Mechanism (RRM) over alleged denials of workers' rights. At the same time, the Trump administration declined to renew the USMCA in its current form during the July 1 joint review, leaving labor enforcement among the issues likely to shape continued negotiations with Canada and Mexico.

The Big Picture

USMCA substantially changed how labor obligations operate in North American trade. Unlike NAFTA, which addressed labor through a separate side agreement, USMCA incorporated labor obligations into the core agreement and made them subject to the same general dispute settlement system as other enforceable commitments. The agreement requires the parties to adopt and maintain internationally recognized labor rights, effectively enforce their labor laws, prohibit imports of goods produced by forced labor, and address violence against workers exercising labor rights.

Congress provided $180 million through the USMCA Implementation Act to support labor law reform and technical assistance in Mexico and additional funding for federal monitoring and enforcement. The law also established the Independent Mexico Labor Expert Board to monitor and evaluate Mexico's implementation of its labor reform obligations and advise Congress and the executive branch.

The agreement's most novel labor enforcement tool is the Rapid Response Labor Mechanism, which allows the United States and Mexico to seek expedited reviews of alleged denials of freedom of association and collective bargaining rights at specific covered facilities. Remedies can ultimately include suspension of preferential tariff treatment, penalties on goods or services from a covered facility, or denial of entry for goods from repeat offenders.

The United States has repeatedly invoked the mechanism at Mexican facilities in industries including automobiles, auto parts, mining, food production, manufacturing, and services. Some cases have been resolved through remediation, while others have proceeded to formal panels. In March, the United States secured its second panel victory under the RRM in a dispute involving the Camino Rojo mine in Zacatecas.

Federal support for Mexican labor enforcement also remains active. In January, the Labor Department awarded $23.4 million for projects aimed at strengthening labor law enforcement in Mexico in sectors that compete with U.S. businesses. That continued investment contradicts the draft's assertion that the Trump administration broadly terminated technical assistance supporting USMCA labor enforcement.

Forced labor enforcement has nevertheless become a separate source of trade friction. The Office of the United States Trade Representative (USTR) determined that both Canada and Mexico had failed to effectively enforce their existing prohibitions on imports made with forced labor. On July 23, USTR imposed additional 10% Section 301 tariffs on products from both countries, subject to specified exemptions.

The action was broader than the USMCA, covering 60 economies. USTR found that Canada, Mexico, Ecuador, the European Union, Indonesia, and Pakistan had adopted forced labor import prohibitions but failed to enforce them effectively.

The Bottom Line

At the July 1 USMCA joint review, the United States declined to renew the agreement in its current form. USTR said the agreement therefore was not renewed but would remain in force while the United States continued negotiations with Canada and Mexico or until its eventual termination under the agreement's provisions.

U.S. and Mexican officials discussed labor during bilateral talks surrounding the joint review, alongside rules of origin, agriculture, economic security, and other trade issues.

The future of USMCA labor enforcement is tied to the broader renegotiation. The RRM has given the United States a facility-specific enforcement tool that did not exist under NAFTA, while recent U.S. action against Canada and Mexico over forced labor imports shows that the administration is also willing to use trade authorities outside USMCA to pressure both countries on labor-related practices.
