Sheinbaum report says 3,109 cases of fuel-tax fraud were detected and regularized

Mexico’s federal government says it detected 3,109 cases of “fiscal huachicol,” a term it uses for incorrect tariff classification involving petroleum products and hydrocarbons. According to President Claudia Sheinbaum’s second government report, the cases were later regularized to strengthen tax collection.

The report presented to Congress places the findings within a broader strategy to improve oversight, combat tax evasion and tackle smuggling in foreign trade. It also says authorities issued 72 information cards on illicit substances for the relevant agencies, seeking to strengthen intelligence, control and interception efforts involving substances considered a major threat to Mexico’s security.

A customs-law reform that took effect in 2026 introduced measures to modernize clearance procedures, improve the traceability of foreign-trade operations and refine risk-management systems. The government says tighter fiscal controls and the regulatory changes produced 9.676 billion pesos in additional revenue between September 2025 and June 2026, representing a real increase of 68.2%.

The National Customs Agency of Mexico collected 1.449 trillion pesos in 2025, equal to 27.1% of total tax revenue and 4.1% of gross domestic product. From January through June 2026, its collection reached 659.393 billion pesos, or 3.7% of GDP. Authorities also issued 930 seizure or retention orders over suspected under-valuation, with estimated productivity of 339.1 million pesos. The agency and the Tax Administration Service identified companies and authorized third parties accused of irregular conduct, unpaid contributions or breaches of trade rules. Those actions began procedures to cancel six strategic bonded facilities and 19 customs brokers.
