Customs and Duties
Puerto Rico is considered a part of the United States for customs purposes, so you will not pass through customs on arrival if you're coming from the mainland. When leaving Puerto Rico, you must pass your bag through a checkpoint of the U.S. Department of Agriculture's (USDA) Animal and Plant Health Inspection Service (APHIS). The list of organic products that can be transported from Puerto Rico to the States includes avocados, bananas, breadfruits, citrus fruits, ginger, papayas, and plantains.
