This document amends Customs and Border Protection (CBP) regulations to reflect the extension of import restrictions on certain categories of archaeological material from the Pre-Hispanic cultures of the Republic of Nicaragua. The restrictions, which were originally imposed by Treasury Decision (T.D.) 00-75 and extended by CBP Decision (Dec.) 05-33, are due to expire on October 20, 2010. The Assistant Secretary for Educational and Cultural Affairs, United States Department of State, has determined that factors continue to warrant the imposition of import restrictions. Accordingly, these import restrictions will remain in effect for an additional 5 years, and the CBP regulations are being amended to reflect this extension until October 20, 2015. These restrictions are being extended pursuant to determinations of the United States Department of State made under the terms of the Convention on Cultural Property Implementation Act that implemented the United Nations Educational, Scientific and Cultural Organization (UNESCO) Convention on the Means of Prohibiting and Preventing the Illicit Import, Export and Transfer of Ownership of Cultural Property. T.D. 00-75 contains the Designated List of archaeological material representing Pre-Hispanic cultures of Nicaragua to which the restrictions apply.
