The International Union of Leather Technologists and Chemists Societies, a world-wide organization of professional societies, was originally organized in London in 1897. There are currently 18 Member Societies and 5 Associate Members representing some 3000 individual members.
According to the IULTCS statutes the aims of the Union are to foster cooperation between member societies, to hold congresses to further the advancement of leather science and technology, to form commissions for special studies and to establish international methods of samples and testing leather and materials associated with leather manufacture.
The IULTCS organization has held 35 Congresses in nineteen different countries on five continents. In 2021 the IULTCS will add another new country when the Congress will be held in Ethiopia.
