CBP, or U.S. Customs and Border Protection, is a critical agency under the United States Department of Homeland Security. Formed in 2003, CBP's primary responsibilities include the regulation and facilitation of international travel and trade into the United States. The agency plays a crucial role in enhancing national security through comprehensive border management and control. CBP officers scrutinize import documents such as commercial invoices and packing lists to ensure compliance with U.S. laws and regulations. They also collect import duties which are crucial for the nation's economy. Additionally, CBP has the authority to select shipments for detailed examination, which helps prevent illegal and potentially harmful goods from entering the U.S. The agency's activities are essential in preventing terrorism, managing immigration, and protecting America's agricultural interests from pests and diseases by enforcing U.S. regulations.
