 Maquiladoras (manufacturing plants that take in imported raw materials and produce goods for domestic consumption and export on behalf of foreign companies) have become the landmark of trade in Mexico.This sector has benefited from NAFTA, in that real income in the maquiladora sector has increased 15.5% since 1994, though from the non-maquiladora sector has grown much faster.Contrary to popular belief, this should be no surprise since maquiladora's products could enter the US duty-free since the 1960s industry agreement.
