Peru’s customs office (aduana) is notorious for being strict with travelers coming back from Miami with loads of imported goodies. That is why you will see a line of Limeños nervously waiting to pass through the stoplight at the Peruvian customs checkpoint. If you get the unlucky red light, you should know the rules. Travelers are allowed to bring three liters of alcohol and 20 packs of cigarettes into Peru duty-free. You can also bring in US$300 worth of gifts, but not to trade or sell.
On your way home, it is illegal to leave Peru with genuine archaeological artifacts, historic art, or animal products from endangered species. If you’re caught you will surely be arrested and prosecuted. Your home country will not let you bring in coca leaves but rarely do they hassle you about coca teabags.
