Mexico Renews ‘Autos Chocolate’ Decree

Mexico’s Congress has reapproved the federal decree allowing the regularization of illegally imported used vehicles—known as autos chocolate—extending a policy that has already brought nearly 3 million units into the formal registry. According to figures cited in the decree’s latest renewal, about 2.99 million vehicles had been legalized by November 2024, up from fewer than 50,000 units when the program began in mid-2022. 

The measure, originally presented as a way to provide legal certainty to vehicle owners and improve road safety, remains in force as lawmakers expand its scope and duration. The decree allows owners of used vehicles imported mainly from the United States to register them after paying a fixed fee and meeting basic documentation requirements. Federal authorities argue that the program has generated billions of pesos in revenue earmarked for local road infrastructure and has reduced the number of unregistered vehicles circulating on public roads. Government data cited in congressional discussion show a steady month-by-month increase in regularizations, with cumulative totals rising sharply in 2023 and 2024.

However, the extension has drawn criticism from industry groups and environmental specialists. While the United States allows the entry of used vehicles only under limited conditions, critics argue that Mexico’s policy has effectively expanded its vehicle fleet with older models. Experts warn that this trend increases emissions, road safety risks, and long-term public costs. “By incorporating older vehicles into the national fleet, the country is assuming higher environmental and safety costs that are not immediately visible,” specialists cited in the report said, warning of long-term impacts on public health and infrastructure.

Data referenced alongside the decree indicate that most regularized vehicles are more than a decade old and have limited emissions controls compared with newer models. This has raised concerns that the policy runs counter to Mexico’s environmental and climate goals, particularly as the government promotes cleaner mobility solutions. Analysts quoted in the article said the measure may temporarily benefit households by providing legal status to low-cost vehicles, but also delays fleet renewal and the adoption of more efficient technologies.

Automotive industry representatives have also expressed concern about market distortions, arguing that the influx of legalized used vehicles competes directly with new and domestically sold used cars, affecting demand and pricing across the sector. “This program alters the competitive balance of the automotive market and discourages investment in newer, safer vehicles,” industry voices said in reactions cited by the publication.

From a fiscal perspective, the government maintains that the decree has provided resources to states and municipalities, particularly in border regions where autos chocolate have historically been more prevalent. Authorities have defended the extension by arguing that the policy responds to social realities and aims to bring informal assets into the formal economy. Critics, however, counter that the lack of stricter technical and environmental requirements undermines those benefits.

A presidential decree published on Dec. 31, 2025, had ended the legal framework that since 2022 allowed the regularization of nearly 3 million illegally imported vehicles. In January 2026, the Ministry of Security said there was “no valid provision” authorizing such procedures and warned that vehicles processed through irregular mechanisms could be seized.
