Which statement best describes the role of customs at an international airport?

The role of customs at an international airport primarily involves inspecting and appraising goods and credentials. This process is crucial to ensuring that all items entering a country comply with its laws and regulations, particularly in relation to trade and security. Customs officials check passports and travel documents to verify the identity and legality of passengers entering the country. They also examine luggage and goods to ensure that no prohibited items are brought in and that all applicable duties and taxes are properly assessed. This helps maintain national security, public health, and tax integrity, contributing to the overall regulatory framework governing international travel and trade.

Other roles mentioned, such as passenger comfort, airline efficiency, or food services, do not fall under the primary responsibilities of customs, which is focused specifically on regulation and enforcement concerning international commerce and travel.
