This final rule amends the U.S. Customs and Border Protection (CBP) regulations to reflect an extension of import restrictions on certain archaeological and ethnological materials from the Plurinational State of Bolivia ("Bolivia"). The restrictions, which were originally imposed by Treasury Decision (T.D.) 01-86 and last extended by CBP Dec. 11-24, are due to expire on December 4, 2016. The Assistant Secretary for Educational and Cultural Affairs, United States Department of State, has determined that conditions continue to warrant the imposition of import restrictions. Accordingly, these import restrictions will remain in effect for an additional five years, and the CBP regulations are being amended to reflect this extension through December 4, 2021. 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 in accordance with 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. 01-86 contains the Designated List of archaeological and ethnological materials from Bolivia to which the restrictions apply.
