Tech goods lead 2011 seizures by Customs

China continues to be the leading source for seized counterfeit and pirated goods, accounting for 62 percent of the total domestic value of the seizures. Consumer electronics were the top commodity seized, with a third of the category made up of infringing cellphones and smartphones.

"The growth of websites selling counterfeit goods directly to consumers is one reason why CBP and ICE have seen a significant increase in the number of seizures at mail and express courier facilities," said acting CBP Commissioner David Aguilar.

"Although these websites may have low prices, what they do not tell consumers is that the true costs to our nation and consumers include lost jobs, stolen business profits, threats to our national security, and a serious risk of injury to consumers."

Other leading categories of products seized include critical technology components, electronic articles, cigarettes, batteries, perfumes and pharmaceuticals. The total value of the goods seized declined slightly, to $1.1 billion.
