What is meant by 'duty-free' allowance for passengers?

The term 'duty-free' allowance refers to the limits on quantities of goods that passengers can bring into a country without having to pay import taxes or duties. This concept is essential for international travelers, as it outlines the maximum amount of certain items—such as alcohol, tobacco, perfumes, and other goods—that a passenger can purchase at a duty-free shop or bring in from abroad without incurring additional financial obligations to customs authorities. Each country has its own regulations regarding what goods are included in the duty-free allowance and the specific limits placed on those goods.

The other options do not accurately capture the meaning of 'duty-free' allowance. For instance, restrictions on passenger movement in the cabin pertain to safety and security regulations rather than financial allowances for goods. Allowances for free beverages during flights are related to in-flight services, not customs allowances. Finally, permits for carrying extra luggage without fees deal with baggage policies and fees, which do not intersect with the concept of duty-free goods and tax exemptions.
