A customs exam, also known as a customs inspection or examination, is a process conducted by customs authorities to scrutinize a shipment upon its import into a country. It is carried out to verify the accuracy of the customs declaration and ensure compliance with customs regulations. The purpose of a customs exam is to detect and prevent the entry of contraband, illegal goods, or prohibited items. During the examination, customs officials physically inspect the shipment to confirm that the actual contents match the information provided in the customs declaration. They may also assess the value of the goods to ensure accurate self-assessment. The customs exam is an important measure to maintain the integrity of the customs process and safeguard national security and trade interests.
