This document adopts as a final rule, without change, the interim rule amending the Customs Regulations that was published in the Federal Register on February 4, 2000, as T.D. 00-7. The interim rule set forth the form and manner by which an importer establishes that a valid export certificate is in effect for certain sugar-containing products subject to a tariff-rate quota, that are products of a participating country, as defined in regulations of the United States Trade Representative (USTR). The export certificate is necessary to enable the importer to claim the in-quota rate of duty on the sugar- containing products.
