Protecting the nation's borders, the U.S. Customs Service is the only border agency with enforcement and intelligence forces. Customs inspects baggage and cargo entering the country for smuggled and illicit items. On a typical day, U.S. Customs Service seizes more than 4,000 pounds of narcotics, $32,000 in weapons and about $560,000 in currency. The agency also regulates some aspects of importing and exporting.
