Mexico’s Congress has approved a sweeping Customs Law reform aimed at tightening control over imports and exports and tackling fiscal evasion linked to the so-called “huachicol fiscal.” The reform eliminates previous clauses that exempted customs agents from liability, making them jointly responsible with importers and exporters for tax compliance. It also introduces stricter digital oversight, new penalties for customs operators, and the creation of a Customs Council led by the Ministry of Finance.

The move comes as authorities investigate massive losses from illegal fuel imports, estimated at nearly 23 billion pesos this year. Critics argue that while the reform strengthens the government’s fiscal grip, it may overburden legitimate trade operations and increase bureaucratic complexity.

The Air Infrastructure, Communications, and Transportation Ministry (SICT) replaced General Miguel Vallín Osuna over alleged corruption and appointed retired General Emilio Avendaño García as the new director of the Federal Civil Aviation Agency (AFAC). 

The change was made effective October 1, 2025. Apart from leadership turnover, the move also included the dismissal of other top AFAC officials linked to Vallín’s team.

A new wave of dismissals is hitting the Federal Judiciary despite a call from the Supreme Court’s president to avoid such actions. Since mid-September, at least 5,000 trusted employees including clerks, secretaries, and officers with over a decade of experience have reportedly been removed, while around 40,000 unionized workers remain protected.

The dismissals have raised concerns about lack of severance, loss of seniority benefits, gender parity issues in appointments,and the risk that inexperienced staff could slow judicial efficiency.

Mexico’s Economy Secretary Marcelo Ebrard confirmed that Mexico will hold talks with China, South Korea, India, and other Asian nations regarding a proposal to raise tariffs on 1,463 product categories. The measure aims to reduce Mexico’s growing trade deficit with Asia, which expanded 83% from 2020 to 2024. 

Ebrard stressed that the action is not targeted at any single country but responds to unfair trade practices and dumping that have hurt domestic producers. He also dismissed the likelihood of retaliatory measures, noting that Mexico remains a key buyer of Asian exports.

Mexico faces a major challenge in transportation ahead of the 2026 FIFA World Cup. Experts warn that with over 5 million visitors expected, airports, highways, and urban infrastructure could experience significant congestion if preparations are not accelerated.

Mario Veraldo, a logistics specialist, stressed that early planning is critical. Without timely coordination between airports, cities, and government agencies, Mexico risks logistical chaos. The tournament is also seen as an opportunity to showcase Mexico as a modern, safe, and sustainable destination.
