Footwear maker RG Barry Corporation said today that the accelerated elimination of US and Mexican tariffs on slippers under the North American Free Trade Agreement (NAFTA), which came into effect on January 1, 2002, is an important part of its strategy to compete profitably in global markets. The 15 per cent duty on US slippers made in Mexico was removed as a part of round three of the NAFTA tariff acceleration exercise that eliminated tariffs on a range of Mexican products.
