Counterfeiter Tricks of the Trade: How Fake Goods Might Get Past Inspectors

— -- U.S. Customs and Border Protection and U.S. Immigration and Customs Enforcement are inspecting suspicious boxes pulled off of planes, trains and cargo ships at several secret locations all over the country. Inside some of these boxes are countless counterfeit goods, and it’s the agents’ jobs to spot these fakes before they make it to store shelves and maybe even inside your home.

As part of a nearly year-long investigation into counterfeit goods, ABC News’ “20/20” was allowed inside these inspection locations in Newark, New Jersey, Miami and Los Angeles.

To get the knockoff items past inspectors, Robert Perez, U.S. Customs and Border Protection Director of Field Operations, says he’s seen counterfeiters utilize several tactics to conceal brand names on the fake goods.

"We see nationally well over 25 million cargo containers on vessels, trucks and rail cars every year,” Perez told “20/20.” “The same counterfeits not only undermine the economic security of the country, but they raise many health and safety concerns as well.”
