Lázaro Cárdenas, Michoacán — Mexican federal security authorities identified and seized a shipment of imported goods from Shanghai, China, containing 27,200 kilograms of tartaric acid at the customs office in the municipality of Lázaro Cárdenas, Michoacán.

The country’s Security Cabinet said in a post on X that risk analysis, customs controls and documentary tracking led to the detention of more than 27,200 kilograms of the substance, which is used to produce methamphetamine.

“These actions strengthen customs intelligence, surveillance at the country’s points of entry and the detection of operations that may be linked to illicit activities,” the cabinet said.

The seizure involved personnel from Mexico’s National Customs Agency (ANAM), the Secretariat of Security and Citizen Protection (SSPC), the Mexican Navy (Semar) and the Federal Prosecutor’s Office (FGR).

Tartaric acid is a controlled chemical precursor, and its interception adds to a series of recent seizures of precursor chemicals and synthetic drugs at Mexican ports, airports and laboratories.
