Section 782.10 - Identification of commodities subject to end-use certificate regulations(a) The regulations in this part are applicable to wheat and barley, respectively, imported into the U.S. from any foreign country, as defined in 19 CFR 134.1 , or instrumentality of such foreign country that, as of April 8, 1994, required end-use certificates for imports of U.S.-produced wheat or barley.(b) Because Canada is the only country with such requirements on wheat, and no country has an end-use certificate requirement for barley, only wheat originating in Canada is affected by the regulations in this part.
