Prospective buyers are advised that several countries prohibit altogether the importation of property containing such materials, and that other countries require a permit (e. g. , a CITES permit) from the relevant regulatory agencies in the countries of exportation as well as importation. The sale of ivory, tortoiseshell and other materials derived from endangered species is limited by CITES regulations to 'worked' pieces dating prior to 1947, and the export of such pieces outside the EU would require an export licence to be obtained from DEFRA.
