The 9/11 attacks in New York marked the beginning of a precautionary era of increased international terrorism, affecting the operations of international agencies and homeland security authorities. Before this, the main priority of the U.S. Customs and Border Protection services was to prevent the smuggling of illegal substances into the country and to avoid importers from misclaiming the value of imported goods. However, CBP’s responsibilities have now extended to protecting the country and monitoring any security risk that comes in from international grounds.
Nowadays, the U.S. Customs targets, pulls, and examines any questionable shipment that enters the United States. Customs cargo inspectors have a system in place that gives scores to each shipment, and if that score is over a certain number (standard), it triggers an interest in the further review and examination of these goods.
