On December 5, 2017, U.S. Customs and Border Protection (CBP) published in the Federal Register a final rule [CBP Dec. 17–19] that amends the CBP regulations to reflect the imposition of emergency import restrictions on certain archaeological and ethnological materials from Libya. The Acting Under Secretary for Public Diplomacy and Public Affairs, United States Department of State, has determined that conditions warrant the imposition of emergency import restrictions on categories of archaeological and ethnological materials from Libya, which represent the cultural heritage of Libya. The Federal Register document contains the Designated List of Archaeological and Ethnological Material of Libya that describes the types of objects or categories of archaeological or ethnological material to which the import restrictions apply. The emergency import restrictions imposed on certain archaeological and ethnological materials from Libya will be in effect for a five-year period. These restrictions are being imposed pursuant to determinations of the United States Department of State made under the terms of the Convention on Cultural Property Implementation Act, which implements the 1970 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.
