Customs and Border Protection officers seized $8.1 million worth of methamphetamine during a routine inspection of a tractor trailer that entered the United States from Mexico last week.

The drugs were discovered concealed inside a shipment of tiles during the standard truck inspection. Officers found the methamphetamine hidden within the tile cargo as the vehicle underwent processing at the border crossing.

The seizure represents a significant drug bust for CBP, which regularly conducts inspections of commercial vehicles and cargo entering the United States. The methamphetamine was valued at $8.1 million according to agency estimates.

Details about the specific border crossing location, the exact date of the seizure, and whether any arrests were made in connection with the shipment were not immediately available. CBP has not released information about the origin or intended destination of the tile shipment.

The incident highlights ongoing efforts by federal agencies to intercept illegal drug trafficking operations that attempt to smuggle narcotics across the U.S.-Mexico border using commercial cargo as cover.
