Regulations about what you can bring into Barbados are fairly standard, apart from the prohibition on importing rum and foreign matches. Note that camouflage clothing is also a prohibited import.
Nearly all visitors will enter the country through Grantley Adams International Airport or Bridgetown’s cruise-ship terminal. All foreigners entering Barbados should be in possession of a valid passport and a return or onward ticket. Although it’s not often enforced, officers may ask for proof that you have a ticket back to your country of origin or residence. So if you are island hopping, show that you intend to eventually return home, and if you live outside the country of your passport, have your residency permit with you.
Cruise-ship passengers who stay less than 24 hours are not required to carry a valid passport.
Visas are not required for citizens of the US, Canada and most European and Commonwealth countries.
