What are the duty-free allowances for alcohol and tobacco products?

The duty-free allowances for alcohol and tobacco products vary depending on the traveler's age and the specific product. Generally, individuals aged 21 and above can bring in one liter (33.8 ounces) of alcohol duty-free, as long as it is for personal use and not for resale. They can also bring in up to 200 cigarettes or 100 cigars or 2 kilograms (4.4 pounds) of tobacco. However, additional restrictions may apply depending on the country of origin and destination. It is important for travelers to familiarize themselves with the specific regulations in order to comply with Customs and Border Protection requirements and avoid potential fines or confiscation of goods.
