The Andean Trade Preference Act was enacted in 1991 to combat drug production and trafficking in the Andean countries: Bolivia, Colombia, Ecuador and Peru. The program offers trade benefits to help these countries develop and strengthen legitimate industries. ATPA was expanded under the Trade Act of 2002, and is now called the Andean Trade Promotion and Drug Eradication Act. It provides duty-free access to U.S. markets for approximately 5,600 products.
