What the free port means, and what it doesn’t
Margarita Island, the state of Nueva Esparta, has a special free-port regime (Puerto Libre): imported goods sold on the island are exempt from most of the customs duties charged on the Venezuelan mainland. Congress created the free zone on 16 August 1966, it took effect on 1 April 1975, and the law in force today dates from 2000. That status is why Venezuelans long flew in to pair a beach week with serious shopping, and why Porlamar grew into a city.
Duty-free on Margarita means cheaper than the Venezuelan mainland, not necessarily cheaper than U.S. retail. For a visitor from the U.S. or Canada, check the home price on your phone before you assume a bargain, especially for electronics. Treat the shopping as an afternoon of a Margarita trip, not the reason for it.
