Authorities in Venezuela said they seized more than 3.4 metric tons of cocaine.
They were convicted in Washington's U.S. District Court after a four-week trial on one count each of conspiring to import and distribute cocaine in the United States.
The gradual implementation of the new rules started last June and is expected to be concluded by January 2016.
The Attorney General's Office (PGR) explained that agents were conducting a routine traffic stop when they found the drug hidden inside a vehicle's air conditioning compressor.
So far this year, authorities in Tamaulipas have taken down 65 antennas that the cartel used for radio communication.
