Most trucks enrolled in the program pause at the border for just 20 seconds before entering the United States. And nine of 10 of them do so without anyone looking at their cargo.
But among the small fraction of trucks that are inspected, authorities have found multiple loads of contraband, including eight tons of marijuana seized during one week in April. Some experts now question whether the program makes sense at a time when drug traffickers are willing to do almost anything to smuggle their shipments into the U.S.
More than half of all U.S. imports now come from companies in the program, called the Customs-Trade Partnership Against Terrorism, or C-TPAT. Mexican trucking companies make up only 6 percent of global membership in the system, but they account for half of its 71 security violations during the past two years.
Participants kept secretThe trusted-shipper system "just tells the bad guys who to target," said Dave McIntyre, former director of the Integrative Center for Homeland Security at Texas A&M University.
The program works like this: Participating companies agree to adopt certain security measures in exchange for fast entry into the U.S.
They must put their employees through background checks, fence in their facilities and track their trucks. They also are asked to work with subcontractors who also have been certified under the program, which is run by the U.S. Customs and Border Protection agency.
The government keeps the list of participants secret, citing national security and trade secrets. But some of the 9,500 companies who are part of the system advertise their membership to drum up business, making them targets for smugglers, who can then threaten drivers or offer them bribes, critics say.
Mexican trucking companies face higher scrutiny than others. They get a full customs inspection every year, instead of every three years like other participating companies.
