Numerous free trade zones make the Dominican Republic attractive to export-import businesses. Some FTZ businesses moved to Mexico after the NAFTA agreement.
Clothing production brings in the majority of export revenues (32%), but the commodity market also supports the export of pig iron (7.8%), medical instruments (7.7%), sugar (5.6%), and electrical parts (5.1%). Dominican Republic imports include food, petroleum, cotton and fabrics, chemicals, and pharmaceuticals.
