Data on U.S. Food and Drug Administration import detentions and alerts are used to quantify regulatory barriers experienced by Asian food products entering the United States. These data offer the only comprehensive means of assessing regulatory barriers without relying on expert opinion, although they fall short of placing a dollar value on the volume of trade affected. The data show that meeting food regulations is a significant barrier to Asian food products entering the United States, especially for products originating in developing and newly industrialized countries.
