Nearly 5,000 counterfeit Apple iPhone products were confiscated by U.S. Customs and Border Protection (CBP) officers at the Port of San Diego, authorities said on Wednesday.

CBP officers inspected a shipment from Portugal last month at an airport warehouse which were labeled as "back covers" and "polarizers," according to CBP.

Officers found counterfeit iPhone backings and LCD screens for various iPhone models.

There were a total of 4,820 fake iPhone parts, valued at 222,113 U.S. dollars, if real, CBP said.

"One of our goals is to protect American consumers and U.S. industry from the threats posed by counterfeiting and piracy," said Port of San Diego Director Bill Snyder in a statement.

CBP has created a public awareness campaign that warns of the dangers of purchasing counterfeit goods. Impacts can include the loss of jobs in the United States, support of organized crime, and risks to health and safety.
