If you buy cigars from America and have them shipped into your country, you will be responsible for duty. Every country has a different tax rate and the duty due will change based on the country where you live. Normally, shipping a single box of cigars that weighs less than 2 pounds will not be checked by Customs if it is declared as a gift. Packages over 2 pounds run a higher chance of checking by Customs. Packages over 5 pounds will generally be checked.
