Mexico intensifies investigations into the fuel smuggling of drug cartels

Mexico has expanded its investigation into fuel smuggling in seaports, which was highlighted?in an investigation 2025 into cartel-linked crimes.

According to the February document, the anti-corruption minister is in charge of internal investigations at the ports of Guaymas and Tampico as well as Ensenada. It also oversees the Navy and Customs Agency.

The government had previously acknowledged investigations into suspected fuel smuggling in the Port of Tampico, and 14 people were arrested last year for allegedly being involved. These included customs agents and Navy officers.

The government's comments on fuel smuggling were in response to questions posed by the National Action Party (PAN), an opposition party, about the alleged?corruption in state agencies which allowed fuel smuggling in Mexico to flourish. The fuel smuggling part was part of a 217-page answer to senators' questions about the administration’s performance in achieving its policy goals.

Local media first reported on the section of this document that is available on the Senate's website.

Mexico's Attorney General, Navy, or Customs Agency did not respond to requests for comment. Neither did the port administrations in Guaymas and Tampico, nor Ensenada.

Fuel smuggling is a Mexican crime that involves falsifying customs and shipping paperwork, mainly on fuel imported from the United States. Smugglers avoid a high Mexican tax on gasoline and diesel by declaring that it is a different type of petroleum product exempt from duty. Savings can be as high as half the value of a shipment.

According to the U.S. Treasury Department, illicit fuel and stolen crude oil are now Mexico's cartels' second largest source of revenue behind narcotics.

Smugglers are now using oil tankers instead of trucks and rails, which is a sign that cartels may be working with corrupt port insiders.

In its investigation of 2025, the government tracked down a'vessel' that discharged imported diesel at the ports Ensenada, and Guaymas, which was declared by?Mexico as a?tax-free fuel, costing $7 million to the government in lost duties.

According to three Mexican security officials, and a document of undated government security that was viewed by us, the importer is suspected to be an unofficial front for the Jalisco New Generation Cartel.

PAN asked the federal government in its questions to explain the steps it was taking to investigate, dismantle, and punish those involved in the fuel-smuggling networks, including any high-ranking officials.

The?U.S. has put intense pressure on the Mexican President Claudia Sheinbaum. President Donald Trump is under pressure to crackdown on drug cartels.
