The legality of bringing Cuban cigars back from Cuba depends on where you are traveling from and to.
If you are a U.S. citizen or resident, it is illegal to purchase or import Cuban cigars, even if you are traveling to Cuba. The U.S. government maintains a trade embargo on Cuba, which includes a ban on the importation of Cuban cigars and other goods into the United States.
There are some limited exceptions to this rule, such as for authorized travelers on official business, journalists, and those visiting close relatives in Cuba, but in general, U.S. citizens and residents are not permitted to bring back Cuban cigars from Cuba.
If you are traveling from a country where Cuban cigars are legal and are not subject to any import restrictions, you may be able to bring them back with you. However, it's important to check the specific laws and regulations of the country you are traveling from, as well as any restrictions that may apply in your destination country.
In general, it's always a good idea to check the customs and import regulations of your destination country to ensure that you are complying with all applicable laws and regulations.
